+

+

+OVERVIEW

+========

+

+This package contains C software to implement JPEG image encoding, decoding,

+and transcoding.  JPEG (pronounced "jay-peg") is a standardized compression

+method for full-color and gray-scale images.

+

+This software implements JPEG baseline, extended-sequential, and progressive

+compression processes.  Provision is made for supporting all variants of these

+processes, although some uncommon parameter settings aren't implemented yet.

+We have made no provision for supporting the hierarchical or lossless

+processes defined in the standard.

+

+We provide a set of library routines for reading and writing JPEG image files,

+plus two sample applications "cjpeg" and "djpeg", which use the library to

+perform conversion between JPEG and some other popular image file formats.

+The library is intended to be reused in other applications.

+

+In order to support file conversion and viewing software, we have included

+considerable functionality beyond the bare JPEG coding/decoding capability;

+for example, the color quantization modules are not strictly part of JPEG

+decoding, but they are essential for output to colormapped file formats or

+colormapped displays.  These extra functions can be compiled out of the

+library if not required for a particular application.

+

+We have also included "jpegtran", a utility for lossless transcoding between

+different JPEG processes, and "rdjpgcom" and "wrjpgcom", two simple

+applications for inserting and extracting textual comments in JFIF files.

+

+The emphasis in designing this software has been on achieving portability and

+flexibility, while also making it fast enough to be useful.  In particular,

+the software is not intended to be read as a tutorial on JPEG.  (See the

+REFERENCES section for introductory material.)  Rather, it is intended to

+be reliable, portable, industrial-strength code.  We do not claim to have

+achieved that goal in every aspect of the software, but we strive for it.

+

+We welcome the use of this software as a component of commercial products.

+No royalty is required, but we do ask for an acknowledgement in product

+documentation, as described under LEGAL ISSUES.

+

+

+LEGAL ISSUES

+============

+

+In plain English:

+

+1. We don't promise that this software works.  (But if you find any bugs,

+   please let us know!)

+2. You can use this software for whatever you want.  You don't have to pay us.

+3. You may not pretend that you wrote this software.  If you use it in a

+   program, you must acknowledge somewhere in your documentation that

+   you've used the IJG code.

+

+In legalese:

+

+The authors make NO WARRANTY or representation, either express or implied,

+with respect to this software, its quality, accuracy, merchantability, or

+fitness for a particular purpose.  This software is provided "AS IS", and you,

+its user, assume the entire risk as to its quality and accuracy.

+

+This software is copyright (C) 1991-2012, Thomas G. Lane, Guido Vollbeding.

+All Rights Reserved except as specified below.

+

+Permission is hereby granted to use, copy, modify, and distribute this

+software (or portions thereof) for any purpose, without fee, subject to these

+conditions:

+(1) If any part of the source code for this software is distributed, then this

+README file must be included, with this copyright and no-warranty notice

+unaltered; and any additions, deletions, or changes to the original files

+must be clearly indicated in accompanying documentation.

+(2) If only executable code is distributed, then the accompanying

+documentation must state that "this software is based in part on the work of

+the Independent JPEG Group".

+(3) Permission for use of this software is granted only if the user accepts

+full responsibility for any undesirable consequences; the authors accept

+NO LIABILITY for damages of any kind.

+

+These conditions apply to any software derived from or based on the IJG code,

+not just to the unmodified library.  If you use our work, you ought to

+acknowledge us.

+

+Permission is NOT granted for the use of any IJG author's name or company name

+in advertising or publicity relating to this software or products derived from

+it.  This software may be referred to only as "the Independent JPEG Group's

+software".

+

+We specifically permit and encourage the use of this software as the basis of

+commercial products, provided that all warranty or liability claims are

+assumed by the product vendor.

+

+

+ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,

+sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.

+ansi2knr.c is NOT covered by the above copyright and conditions, but instead

+by the usual distribution terms of the Free Software Foundation; principally,

+that you must include source code if you redistribute it.  (See the file

+ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part

+of any program generated from the IJG code, this does not limit you more than

+the foregoing paragraphs do.

+

+The Unix configuration script "configure" was produced with GNU Autoconf.

+It is copyright by the Free Software Foundation but is freely distributable.

+The same holds for its supporting scripts (config.guess, config.sub,

+ltmain.sh).  Another support script, install-sh, is copyright by X Consortium

+but is also freely distributable.

+

+The IJG distribution formerly included code to read and write GIF files.

+To avoid entanglement with the Unisys LZW patent, GIF reading support has

+been removed altogether, and the GIF writer has been simplified to produce

+"uncompressed GIFs".  This technique does not use the LZW algorithm; the

+resulting GIF files are larger than usual, but are readable by all standard

+GIF decoders.

+

+We are required to state that

+    "The Graphics Interchange Format(c) is the Copyright property of

+    CompuServe Incorporated.  GIF(sm) is a Service Mark property of

+    CompuServe Incorporated."

+        Wallace, Gregory K.  "The JPEG Still Picture Compression Standard",

+        Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.

+(Adjacent articles in that issue discuss MPEG motion picture compression,

+applications of JPEG, and related topics.)  If you don't have the CACM issue

+handy, a PostScript file containing a revised version of Wallace's article is

+available at http://www.ijg.org/files/wallace.ps.gz.  The file (actually

+a preprint for an article that appeared in IEEE Trans. Consumer Electronics)

+omits the sample images that appeared in CACM, but it includes corrections

+and some added material.  Note: the Wallace article is copyright ACM and IEEE,

+and it may not be used for commercial purposes.

+

+A somewhat less technical, more leisurely introduction to JPEG can be found in

+"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by

+M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1.  This book provides

+good explanations and example C code for a multitude of compression methods

+including JPEG.  It is an excellent source if you are comfortable reading C

+code but don't know much about data compression in general.  The book's JPEG

+sample code is far from industrial-strength, but when you are ready to look

+at a full implementation, you've got one here...

+

+The best currently available description of JPEG is the textbook "JPEG Still

+Image Data Compression Standard" by William B. Pennebaker and Joan L.

+Mitchell, published by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1.

+Price US$59.95, 638 pp.  The book includes the complete text of the ISO JPEG

+standards (DIS 10918-1 and draft DIS 10918-2).

+Although this is by far the most detailed and comprehensive exposition of

+JPEG publicly available, we point out that it is still missing an explanation

+of the most essential properties and algorithms of the underlying DCT

+technology.

+If you think that you know about DCT-based JPEG after reading this book,

+then you are in delusion.  The real fundamentals and corresponding potential

+of DCT-based JPEG are not publicly known so far, and that is the reason for

+all the mistaken developments taking place in the image coding domain.

+

+The original JPEG standard is divided into two parts, Part 1 being the actual

+specification, while Part 2 covers compliance testing methods.  Part 1 is

+titled "Digital Compression and Coding of Continuous-tone Still Images,

+Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS

+10918-1, ITU-T T.81.  Part 2 is titled "Digital Compression and Coding of

+Continuous-tone Still Images, Part 2: Compliance testing" and has document

+numbers ISO/IEC IS 10918-2, ITU-T T.83.

+IJG JPEG 8 introduces an implementation of the JPEG SmartScale extension

+which is specified in two documents:  A contributed document at ITU and ISO

+with title "ITU-T JPEG-Plus Proposal for Extending ITU-T T.81 for Advanced

+Image Coding", April 2006, Geneva, Switzerland.  The latest version of this

+document is Revision 3.  And a contributed document ISO/IEC JTC1/SC29/WG1 N

+5799 with title "Evolution of JPEG", June/July 2011, Berlin, Germany.

+

+The JPEG standard does not specify all details of an interchangeable file

+format.  For the omitted details we follow the "JFIF" conventions, revision

+1.02.  JFIF 1.02 has been adopted as an Ecma International Technical Report

+and thus received a formal publication status.  It is available as a free

+download in PDF format from

+http://www.ecma-international.org/publications/techreports/E-TR-098.htm.

+A PostScript version of the JFIF document is available at

+http://www.ijg.org/files/jfif.ps.gz.  There is also a plain text version at

+http://www.ijg.org/files/jfif.txt.gz, but it is missing the figures.

+

+The TIFF 6.0 file format specification can be obtained by FTP from

+ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz.  The JPEG incorporation scheme

+found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.

+IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6).

+Instead, we recommend the JPEG design proposed by TIFF Technical Note #2

+(Compression tag 7).  Copies of this Note can be obtained from

+http://www.ijg.org/files/.  It is expected that the next revision

+of the TIFF spec will replace the 6.0 JPEG design with the Note's design.

+Although IJG's own code does not support TIFF/JPEG, the free libtiff library

+uses our library to implement TIFF/JPEG per the Note.

+FILE FORMAT WARS

+================

+

+The ISO/IEC JTC1/SC29/WG1 standards committee (also known as JPEG, together

+with ITU-T SG16) currently promotes different formats containing the name

+"JPEG" which is misleading because these formats are incompatible with

+original DCT-based JPEG and are based on faulty technologies.

+IJG therefore does not and will not support such momentary mistakes

+(see REFERENCES).

+There exist also distributions under the name "OpenJPEG" promoting such

+kind of formats which is misleading because they don't support original

+JPEG images.

+We have no sympathy for the promotion of inferior formats.  Indeed, one of

+the original reasons for developing this free software was to help force

+convergence on common, interoperable format standards for JPEG files.

+Don't use an incompatible file format!

+(In any case, our decoder will remain capable of reading existing JPEG

+image files indefinitely.)

+

+Furthermore, the ISO committee pretends to be "responsible for the popular

+JPEG" in their public reports which is not true because they don't respond to

+actual requirements for the maintenance of the original JPEG specification.

+

+There are currently distributions in circulation containing the name

+"libjpeg" which claim to be a "derivative" or "fork" of the original

+libjpeg, but don't have the features and are incompatible with formats

+supported by actual IJG libjpeg distributions.  Furthermore, they

+violate the license conditions as described under LEGAL ISSUES above.

+We have no sympathy for the release of misleading and illegal

+distributions derived from obsolete code bases.

+Don't use an obsolete code base!

+

+

+TO DO

+=====

+

+Version 8 is the first release of a new generation JPEG standard

+to overcome the limitations of the original JPEG specification.

+More features are being prepared for coming releases...

+

+Please send bug reports, offers of help, etc. to jpeg-info@jpegclub.org.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to

+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.

+#

+# Of course, Automake must honor this variable whenever it calls a

+# tool from the auxiliary directory.  The problem is that $srcdir (and

+# therefore $ac_aux_dir as well) can be either absolute or relative,

+# depending on how configure is run.  This is pretty annoying, since

+# it makes $ac_aux_dir quite unusable in subdirectories: in the top

+# source directory, any form will work fine, but in subdirectories a

+# relative path needs to be adjusted first.

+#

+# $ac_aux_dir/missing

+#    fails when called from a subdirectory if $ac_aux_dir is relative

+# $top_srcdir/$ac_aux_dir/missing

+#    fails if $ac_aux_dir is absolute,

+#    fails when called from a subdirectory in a VPATH build with

+#          a relative $ac_aux_dir

+#

+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

+# are both prefixed by $srcdir.  In an in-source build this is usually

+# harmless because $srcdir is `.', but things will broke when you

+# start a VPATH build or use an absolute $srcdir.

+#

+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:

+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

+# and then we would define $MISSING as

+#   MISSING="\${SHELL} $am_aux_dir/missing"

+# This will work as long as MISSING is not called from configure, because

+# unfortunately $(top_srcdir) has no meaning in configure.

+# However there are other variables, like CC, which are often used in

+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+#

+.TH ANSI2KNR 1 "19 Jan 1996"

+.SH NAME

+ansi2knr \- convert ANSI C to Kernighan & Ritchie C

+.SH SYNOPSIS

+.I ansi2knr

+[--varargs] input_file [output_file]

+.SH DESCRIPTION

+If no output_file is supplied, output goes to stdout.

+.br

+There are no error messages.

+.sp

+.I ansi2knr

+recognizes function definitions by seeing a non-keyword identifier at the left

+margin, followed by a left parenthesis, with a right parenthesis as the last

+character on the line, and with a left brace as the first token on the

+following line (ignoring possible intervening comments).  It will recognize a

+multi-line header provided that no intervening line ends with a left or right

+brace or a semicolon.  These algorithms ignore whitespace and comments, except

+that the function name must be the first thing on the line.

+.sp

+The following constructs will confuse it:

+.br

+     - Any other construct that starts at the left margin and follows the

+above syntax (such as a macro or function call).

+.br

+     - Some macros that tinker with the syntax of the function header.

+.sp

+The --varargs switch is obsolete, and is recognized only for

+backwards compatibility.  The present version of

+.I ansi2knr

+will always attempt to convert a ... argument to va_alist and va_dcl.

+.SH AUTHOR

+L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and

+continues to maintain the current version; most of the code in the current

+version is his work.  ansi2knr also includes contributions by Francois

+Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

+ * brace as the first token on the following line (ignoring possible

+ * intervening comments and/or preprocessor directives), except that a line

+ * consisting of only

+ *      identifier1(identifier2)

+ * will not be considered a function definition unless identifier2 is

+ * the word "void", and a line consisting of

+ *      identifier1(identifier2, <<arbitrary>>)

+ * will not be considered a function definition.

+ * ansi2knr will recognize a multi-line header provided that no intervening

+

+        lpd 2000-04-12 backs out Eggert's changes because of bugs:

+        - concatlits didn't declare the type of its bufend argument;

+        - concatlits didn't recognize when it was inside a comment;

+        - scanstring could scan backward past the beginning of the string; when

+        - the check for \ + newline in scanstring was unnecessary.

+

+        2000-03-05  Paul Eggert  <eggert@twinsun.com>

+

+        Add support for concatenated string literals.

+        * ansi2knr.c (concatlits): New decl.

+        (main): Invoke concatlits to concatenate string literals.

+        (scanstring): Handle backslash-newline correctly.  Work with

+        character constants.  Fix bug when scanning backwards through

+        backslash-quote.  Check for unterminated strings.

+        (convert1): Parse character constants, too.

+        (appendline, concatlits): New functions.

+        * ansi2knr.1: Document this.

+

+        lpd 1999-08-17 added code to allow preprocessor directives

+                wherever comments are allowed

+        lpd 1999-04-12 added minor fixes from Pavel Roskin

+                <pavel_roskin@geocities.com> for clean compilation with

+                gcc -W -Wall

+        lpd 1999-03-22 added hack to recognize lines consisting of

+                identifier1(identifier2, xxx) as *not* being procedures

+        lpd 1999-02-03 made indentation of preprocessor commands consistent

+        lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an

+                endless loop; quoted strings within an argument list

+                confused the parser

+        lpd 1999-01-24 added a check for write errors on the output,

+                suggested by Jim Meyering <meyering@ascend.com>

+        lpd 1998-11-09 added further hack to recognize identifier(void)

+                as being a procedure

+        lpd 1998-10-23 added hack to recognize lines consisting of

+                identifier1(identifier2) as *not* being procedures

+        lpd 1997-12-08 made input_file optional; only closes input and/or

+                output file if not stdin or stdout respectively; prints

+                usage message on stderr rather than stdout; adds

+                --filename switch (changes suggested by

+                <ceder@lysator.liu.se>)

+        lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with

+                compilers that don't understand void, as suggested by

+                Tom Lane

+        lpd 1996-01-15 changed to require that the first non-comment token

+CHANGE LOG for Independent JPEG Group's JPEG software

+

+

+Version 8d  15-Jan-2012

+-----------------------

+

+Add cjpeg -rgb option to create RGB JPEG files.

+Using this switch suppresses the conversion from RGB

+colorspace input to the default YCbCr JPEG colorspace.

+This feature allows true lossless JPEG coding of RGB color images.

+The recommended command for this purpose is currently

+cjpeg -rgb -block 1 -arithmetic.

+SmartScale capable decoder (introduced with IJG JPEG 8) required.

+Thank to Michael Koch for the initial suggestion.

+

+Add option to disable the region adjustment in the transupp crop code.

+Thank to Jeffrey Friedl for the suggestion.

+

+Thank to Richard Jones and Edd Dawson for various minor corrections.

+

+Thank to Akim Demaille for configure.ac cleanup.

+

+

+Version 8c  16-Jan-2011

+-----------------------

+

+Add option to compression library and cjpeg (-block N) to use

+different DCT block size.

+All N from 1 to 16 are possible.  Default is 8 (baseline format).

+Larger values produce higher compression,

+smaller values produce higher quality.

+SmartScale capable decoder (introduced with IJG JPEG 8) required.

+

+

+Version 8b  16-May-2010

+-----------------------

+

+Repair problem in new memory source manager with corrupt JPEG data.

+Thank to Ted Campbell and Samuel Chun for the report.

+

+Repair problem in Makefile.am test target.

+Thank to anonymous user for the report.

+

+Support MinGW installation with automatic configure.

+Thank to Volker Grabsch for the suggestion.

+

+

+Version 8a  28-Feb-2010

+-----------------------

+

+Writing tables-only datastreams via jpeg_write_tables works again.

+

+Support 32-bit BMPs (RGB image with Alpha channel) for read in cjpeg.

+Thank to Brett Blackham for the suggestion.

+

+Improve accuracy in floating point IDCT calculation.

+Thank to Robert Hooke for the hint.

+

+

+Version 8  10-Jan-2010

+----------------------

+

+jpegtran now supports the same -scale option as djpeg for "lossless" resize.

+An implementation of the JPEG SmartScale extension is required for this

+feature.  A (draft) specification of the JPEG SmartScale extension is

+available as a contributed document at ITU and ISO.  Revision 2 or later

+of the document is required (latest document version is Revision 3).

+The SmartScale extension will enable more features beside lossless resize

+in future implementations, as described in the document (new compression

+options).

+

+Add sanity check in BMP reader module to avoid cjpeg crash for empty input

+image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error).

+

+Add data source and destination managers for read from and write to

+memory buffers.  New API functions jpeg_mem_src and jpeg_mem_dest.

+Thank to Roberto Boni from Italy for the suggestion.

+

+

+Version 7  27-Jun-2009

+----------------------

+

+New scaled DCTs implemented.

+djpeg now supports scalings N/8 with all N from 1 to 16.

+cjpeg now supports scalings 8/N with all N from 1 to 16.

+Scaled DCTs with size larger than 8 are now also used for resolving the

+common 2x2 chroma subsampling case without additional spatial resampling.

+Separate spatial resampling for those kind of files is now only necessary

+for N>8 scaling cases.

+Furthermore, separate scaled DCT functions are provided for direct resolving

+of the common asymmetric subsampling cases (2x1 and 1x2) without additional

+spatial resampling.

+

+cjpeg -quality option has been extended for support of separate quality

+settings for luminance and chrominance (or in general, for every provided

+quantization table slot).

+New API function jpeg_default_qtables() and q_scale_factor array in library.

+

+Added -nosmooth option to cjpeg, complementary to djpeg.

+New variable "do_fancy_downsampling" in library, complement to fancy

+upsampling.  Fancy upsampling now uses direct DCT scaling with sizes

+larger than 8.  The old method is not reversible and has been removed.

+

+Support arithmetic entropy encoding and decoding.

+Added files jaricom.c, jcarith.c, jdarith.c.

+

+Straighten the file structure:

+Removed files jidctred.c, jcphuff.c, jchuff.h, jdphuff.c, jdhuff.h.

+

+jpegtran has a new "lossless" cropping feature.

+

+Implement -perfect option in jpegtran, new API function

+jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch)

+

+Better error messages for jpegtran fopen failure.

+(DP 203_jpegtran_errmsg.dpatch)

+

+Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c:

+according to Netpbm, the de facto standard implementation of the PNM formats,

+the most significant byte is first. (DP 203_rdppm.dpatch)

+

+Add -raw option to rdjpgcom not to mangle the output.

+(DP 205_rdjpgcom_raw.dpatch)

+

+Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch)

+

+Add extern "C" to jpeglib.h.

+This avoids the need to put extern "C" { ... } around #include "jpeglib.h"

+in your C++ application.  Defining the symbol DONT_USE_EXTERN_C in the

+configuration prevents this. (DP 202_jpeglib.h_c++.dpatch)

+

+

+Version 6b  27-Mar-1998

+-----------------------

+

+jpegtran has new features for lossless image transformations (rotation

+and flipping) as well as "lossless" reduction to grayscale.

+

+jpegtran now copies comments by default; it has a -copy switch to enable

+copying all APPn blocks as well, or to suppress comments.  (Formerly it

+always suppressed comments and APPn blocks.)  jpegtran now also preserves

+JFIF version and resolution information.

+

+New decompressor library feature: COM and APPn markers found in the input

+file can be saved in memory for later use by the application.  (Before,

+you had to code this up yourself with a custom marker processor.)

+

+There is an unused field "void * client_data" now in compress and decompress

+parameter structs; this may be useful in some applications.

+

+JFIF version number information is now saved by the decoder and accepted by

+the encoder.  jpegtran uses this to copy the source file's version number,

+to ensure "jpegtran -copy all" won't create bogus files that contain JFXX

+extensions but claim to be version 1.01.  Applications that generate their

+own JFXX extension markers also (finally) have a supported way to cause the

+encoder to emit JFIF version number 1.02.

+

+djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather

+than as unknown APP0 markers.

+

+In -verbose mode, djpeg and rdjpgcom will try to print the contents of

+APP12 markers as text.  Some digital cameras store useful text information

+in APP12 markers.

+

+Handling of truncated data streams is more robust: blocks beyond the one in

+which the error occurs will be output as uniform gray, or left unchanged

+if decoding a progressive JPEG.  The appearance no longer depends on the

+Huffman tables being used.

+

+Huffman tables are checked for validity much more carefully than before.

+

+To avoid the Unisys LZW patent, djpeg's GIF output capability has been

+changed to produce "uncompressed GIFs", and cjpeg's GIF input capability

+has been removed altogether.  We're not happy about it either, but there

+seems to be no good alternative.

+

+The configure script now supports building libjpeg as a shared library

+on many flavors of Unix (all the ones that GNU libtool knows how to

+build shared libraries for).  Use "./configure --enable-shared" to

+try this out.

+

+New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio.

+Also, a jconfig file and a build script for Metrowerks CodeWarrior

+on Apple Macintosh.  makefile.dj has been updated for DJGPP v2, and there

+are miscellaneous other minor improvements in the makefiles.

+

+jmemmac.c now knows how to create temporary files following Mac System 7

+conventions.

+

+djpeg's -map switch is now able to read raw-format PPM files reliably.

+

+cjpeg -progressive -restart no longer generates any unnecessary DRI markers.

+

+Multiple calls to jpeg_simple_progression for a single JPEG object

+no longer leak memory.

+

+

+Version 6a  7-Feb-96

+--------------------

+

+Library initialization sequence modified to detect version mismatches

+and struct field packing mismatches between library and calling application.

+This change requires applications to be recompiled, but does not require

+any application source code change.

+

+All routine declarations changed to the style "GLOBAL(type) name ...",

+that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the

+routine's return type as an argument.  This makes it possible to add

+Microsoft-style linkage keywords to all the routines by changing just

+these macros.  Note that any application code that was using these macros

+will have to be changed.

+

+DCT coefficient quantization tables are now stored in normal array order

+rather than zigzag order.  Application code that calls jpeg_add_quant_table,

+or otherwise manipulates quantization tables directly, will need to be

+changed.  If you need to make such code work with either older or newer

+versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is

+recommended.

+

+djpeg's trace capability now dumps DQT tables in natural order, not zigzag

+order.  This allows the trace output to be made into a "-qtables" file

+more easily.

+

+New system-dependent memory manager module for use on Apple Macintosh.

+

+Fix bug in cjpeg's -smooth option: last one or two scanlines would be

+duplicates of the prior line unless the image height mod 16 was 1 or 2.

+

+Repair minor problems in VMS, BCC, MC6 makefiles.

+

+New configure script based on latest GNU Autoconf.

+

+Correct the list of include files needed by MetroWerks C for ccommand().

+

+Numerous small documentation updates.

+

+

+Version 6  2-Aug-95

+-------------------

+

+Progressive JPEG support: library can read and write full progressive JPEG

+files.  A "buffered image" mode supports incremental decoding for on-the-fly

+display of progressive images.  Simply recompiling an existing IJG-v5-based

+decoder with v6 should allow it to read progressive files, though of course

+without any special progressive display.

+

+New "jpegtran" application performs lossless transcoding between different

+JPEG formats; primarily, it can be used to convert baseline to progressive

+JPEG and vice versa.  In support of jpegtran, the library now allows lossless

+reading and writing of JPEG files as DCT coefficient arrays.  This ability

+may be of use in other applications.

+

+Notes for programmers:

+* We changed jpeg_start_decompress() to be able to suspend; this makes all

+decoding modes available to suspending-input applications.  However,

+existing applications that use suspending input will need to be changed

+to check the return value from jpeg_start_decompress().  You don't need to

+do anything if you don't use a suspending data source.

+* We changed the interface to the virtual array routines: access_virt_array

+routines now take a count of the number of rows to access this time.  The

+last parameter to request_virt_array routines is now interpreted as the

+maximum number of rows that may be accessed at once, but not necessarily

+the height of every access.

+

+

+Version 5b  15-Mar-95

+---------------------

+

+Correct bugs with grayscale images having v_samp_factor > 1.

+

+jpeg_write_raw_data() now supports output suspension.

+

+Correct bugs in "configure" script for case of compiling in

+a directory other than the one containing the source files.

+

+Repair bug in jquant1.c: sometimes didn't use as many colors as it could.

+

+Borland C makefile and jconfig file work under either MS-DOS or OS/2.

+

+Miscellaneous improvements to documentation.

+

+

+Version 5a  7-Dec-94

+--------------------

+

+Changed color conversion roundoff behavior so that grayscale values are

+represented exactly.  (This causes test image files to change.)

+

+Make ordered dither use 16x16 instead of 4x4 pattern for a small quality

+improvement.

+

+New configure script based on latest GNU Autoconf.

+Fix configure script to handle CFLAGS correctly.

+Rename *.auto files to *.cfg, so that configure script still works if

+file names have been truncated for DOS.

+

+Fix bug in rdbmp.c: didn't allow for extra data between header and image.

+

+Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data.

+

+Fix several bugs in rdrle.c.

+

+NEED_SHORT_EXTERNAL_NAMES option was broken.

+

+Revise jerror.h/jerror.c for more flexibility in message table.

+

+Repair oversight in jmemname.c NO_MKTEMP case: file could be there

+but unreadable.

+

+

+Version 5  24-Sep-94

+--------------------

+

+Version 5 represents a nearly complete redesign and rewrite of the IJG

+software.  Major user-visible changes include:

+  * Automatic configuration simplifies installation for most Unix systems.

+  * A range of speed vs. image quality tradeoffs are supported.

+    This includes resizing of an image during decompression: scaling down

+    by a factor of 1/2, 1/4, or 1/8 is handled very efficiently.

+  * New programs rdjpgcom and wrjpgcom allow insertion and extraction

+    of text comments in a JPEG file.

+

+The application programmer's interface to the library has changed completely.

+Notable improvements include:

+  * We have eliminated the use of callback routines for handling the

+    uncompressed image data.  The application now sees the library as a

+    set of routines that it calls to read or write image data on a

+    scanline-by-scanline basis.

+  * The application image data is represented in a conventional interleaved-

+    pixel format, rather than as a separate array for each color channel.

+    This can save a copying step in many programs.

+  * The handling of compressed data has been cleaned up: the application can

+    supply routines to source or sink the compressed data.  It is possible to

+    suspend processing on source/sink buffer overrun, although this is not

+    supported in all operating modes.

+  * All static state has been eliminated from the library, so that multiple

+    instances of compression or decompression can be active concurrently.

+  * JPEG abbreviated datastream formats are supported, ie, quantization and

+    Huffman tables can be stored separately from the image data.

+  * And not only that, but the documentation of the library has improved

+    considerably!

+

+

+The last widely used release before the version 5 rewrite was version 4A of

+18-Feb-93.  Change logs before that point have been discarded, since they

+are not of much interest after the rewrite.

+.SH NAME

+cjpeg \- compress an image file to a JPEG file

+.SH SYNOPSIS

+.B cjpeg

+[

+.I options

+]

+[

+.I filename

+]

+.LP

+.SH DESCRIPTION

+.LP

+.B cjpeg

+compresses the named image file, or the standard input if no file is

+named, and produces a JPEG/JFIF file on the standard output.

+The currently supported input file formats are: PPM (PBMPLUS color

+format), PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster

+Toolkit format).  (RLE is supported only if the URT library is available.)

+.SH OPTIONS

+All switch names may be abbreviated; for example,

+.B \-grayscale

+may be written

+.B \-gray

+or

+.BR \-gr .

+Most of the "basic" switches can be abbreviated to as little as one letter.

+Upper and lower case are equivalent (thus

+.B \-BMP

+is the same as

+.BR \-bmp ).

+British spellings are also accepted (e.g.,

+.BR \-greyscale ),

+though for brevity these are not mentioned below.

+.PP

+The basic switches are:

+.TP

+.BI \-quality " N[,...]"

+Scale quantization tables to adjust image quality.  Quality is 0 (worst) to

+100 (best); default is 75.  (See below for more info.)

+.TP

+.B \-grayscale

+Create monochrome JPEG file from color input.  Be sure to use this switch when

+compressing a grayscale BMP file, because

+.B cjpeg

+isn't bright enough to notice whether a BMP file uses only shades of gray.

+By saying

+.BR \-grayscale ,

+you'll get a smaller JPEG file that takes less time to process.

+.TP

+.B \-rgb

+Create RGB JPEG file.

+Using this switch suppresses the conversion from RGB

+colorspace input to the default YCbCr JPEG colorspace.

+Use this switch in combination with the

+.BI \-block " N"

+switch (see below) for lossless JPEG coding.

+.TP

+.B \-optimize

+Perform optimization of entropy encoding parameters.  Without this, default

+encoding parameters are used.

+.B \-optimize

+usually makes the JPEG file a little smaller, but

+.B cjpeg

+runs somewhat slower and needs much more memory.  Image quality and speed of

+decompression are unaffected by

+.BR \-optimize .

+.TP

+.B \-progressive

+Create progressive JPEG file (see below).

+.TP

+.BI \-scale " M/N"

+Scale the output image by a factor M/N.  Currently supported scale factors are

+M/N with all N from 1 to 16, where M is the destination DCT size, which is 8

+by default (see

+.BI \-block " N"

+switch below).

+.TP

+.B \-targa

+Input file is Targa format.  Targa files that contain an "identification"

+field will not be automatically recognized by

+.BR cjpeg ;

+for such files you must specify

+.B \-targa

+to make

+.B cjpeg

+treat the input as Targa format.

+For most Targa files, you won't need this switch.

+.PP

+The

+.B \-quality

+switch lets you trade off compressed file size against quality of the

+reconstructed image: the higher the quality setting, the larger the JPEG file,

+and the closer the output image will be to the original input.  Normally you

+want to use the lowest quality setting (smallest file) that decompresses into

+something visually indistinguishable from the original image.  For this

+purpose the quality setting should be between 50 and 95; the default of 75 is

+often about right.  If you see defects at

+.B \-quality

+75, then go up 5 or 10 counts at a time until you are happy with the output

+image.  (The optimal setting will vary from one image to another.)

+.PP

+.B \-quality

+100 will generate a quantization table of all 1's, minimizing loss in the

+quantization step (but there is still information loss in subsampling, as well

+as roundoff error).  This setting is mainly of interest for experimental

+purposes.  Quality values above about 95 are

+.B not

+recommended for normal use; the compressed file size goes up dramatically for

+hardly any gain in output image quality.

+.PP

+In the other direction, quality values below 50 will produce very small files

+of low image quality.  Settings around 5 to 10 might be useful in preparing an

+index of a large image library, for example.  Try

+.B \-quality

+2 (or so) for some amusing Cubist effects.  (Note: quality

+values below about 25 generate 2-byte quantization tables, which are

+considered optional in the JPEG standard.

+.B cjpeg

+emits a warning message when you give such a quality value, because some

+other JPEG programs may be unable to decode the resulting file.  Use

+.B \-baseline

+if you need to ensure compatibility at low quality values.)

+.PP

+The

+.B \-quality

+option has been extended in IJG version 7 for support of separate quality

+settings for luminance and chrominance (or in general, for every provided

+quantization table slot).  This feature is useful for high-quality

+applications which cannot accept the damage of color data by coarse

+subsampling settings.  You can now easily reduce the color data amount more

+smoothly with finer control without separate subsampling.  The resulting file

+is fully compliant with standard JPEG decoders.

+Note that the

+.B \-quality

+ratings refer to the quantization table slots, and that the last value is

+replicated if there are more q-table slots than parameters.  The default

+q-table slots are 0 for luminance and 1 for chrominance with default tables as

+given in the JPEG standard.  This is compatible with the old behaviour in case

+that only one parameter is given, which is then used for both luminance and

+chrominance (slots 0 and 1).  More or custom quantization tables can be set

+with

+.B \-qtables

+and assigned to components with

+.B \-qslots

+parameter (see the "wizard" switches below).

+.B Caution:

+You must explicitly add

+.BI \-sample " 1x1"

+for efficient separate color

+quality selection, since the default value used by library is 2x2!

+.PP

+The

+.B \-progressive

+switch creates a "progressive JPEG" file.  In this type of JPEG file, the data

+is stored in multiple scans of increasing quality.  If the file is being

+transmitted over a slow communications link, the decoder can use the first

+scan to display a low-quality image very quickly, and can then improve the

+display with each subsequent scan.  The final image is exactly equivalent to a

+standard JPEG file of the same quality setting, and the total file size is

+about the same --- often a little smaller.

+.PP

+Switches for advanced users:

+.TP

+.B \-arithmetic

+Use arithmetic coding.

+.B Caution:

+arithmetic coded JPEG is not yet widely implemented, so many decoders will be

+unable to view an arithmetic coded JPEG file at all.

+.TP

+.BI \-block " N"

+Set DCT block size.  All N from 1 to 16 are possible.

+Default is 8 (baseline format).

+Larger values produce higher compression,

+smaller values produce higher quality

+(exact DCT stage possible with 1 or 2; with the default quality of 75 and

+default Luminance qtable the DCT+Quantization stage is lossless for N=1).

+.B Caution:

+An implementation of the JPEG SmartScale extension is required for this

+feature.  SmartScale enabled JPEG is not yet widely implemented, so many

+decoders will be unable to view a SmartScale extended JPEG file at all.

+.TP

+.B \-dct int

+Use integer DCT method (default).

+.TP

+.B \-dct fast

+Use fast integer DCT (less accurate).

+.TP

+.B \-dct float

+Use floating-point DCT method.

+The float method is very slightly more accurate than the int method, but is

+much slower unless your machine has very fast floating-point hardware.  Also

+note that results of the floating-point method may vary slightly across

+machines, while the integer methods should give the same results everywhere.

+The fast integer method is much less accurate than the other two.

+.TP

+.B \-nosmooth

+Don't use high-quality downsampling.

+.TP

+.BI \-restart " N"

+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is

+attached to the number.

+.B \-restart 0

+(the default) means no restart markers.

+.TP

+.BI \-smooth " N"

+Smooth the input image to eliminate dithering noise.  N, ranging from 1 to

+100, indicates the strength of smoothing.  0 (the default) means no smoothing.

+.TP

+.BI \-maxmemory " N"

+Set limit for amount of memory to use in processing large images.  Value is

+in thousands of bytes, or millions of bytes if "M" is attached to the

+number.  For example,

+.B \-max 4m

+selects 4000000 bytes.  If more space is needed, temporary files will be used.

+.TP

+.BI \-outfile " name"

+Send output image to the named file, not to standard output.

+.TP

+.B \-verbose

+Enable debug printout.  More

+.BR \-v 's

+give more output.  Also, version information is printed at startup.

+.TP

+.B \-debug

+Same as

+.BR \-verbose .

+.PP

+The

+.B \-restart

+option inserts extra markers that allow a JPEG decoder to resynchronize after

+a transmission error.  Without restart markers, any damage to a compressed

+file will usually ruin the image from the point of the error to the end of the

+image; with restart markers, the damage is usually confined to the portion of

+the image up to the next restart marker.  Of course, the restart markers

+occupy extra space.  We recommend

+.B \-restart 1

+for images that will be transmitted across unreliable networks such as Usenet.

+.PP

+The

+.B \-smooth

+option filters the input to eliminate fine-scale noise.  This is often useful

+when converting dithered images to JPEG: a moderate smoothing factor of 10 to

+50 gets rid of dithering patterns in the input file, resulting in a smaller

+JPEG file and a better-looking image.  Too large a smoothing factor will

+visibly blur the image, however.

+.PP

+Switches for wizards:

+.TP

+.B \-baseline

+Force baseline-compatible quantization tables to be generated.  This clamps

+quantization values to 8 bits even at low quality settings.  (This switch is

+poorly named, since it does not ensure that the output is actually baseline

+JPEG.  For example, you can use

+.B \-baseline

+and

+.B \-progressive

+together.)

+.TP

+.BI \-qtables " file"

+Use the quantization tables given in the specified text file.

+.TP

+.BI \-qslots " N[,...]"

+Select which quantization table to use for each color component.

+.TP

+.BI \-sample " HxV[,...]"

+Set JPEG sampling factors for each color component.

+.TP

+.BI \-scans " file"

+Use the scan script given in the specified text file.

+.PP

+The "wizard" switches are intended for experimentation with JPEG.  If you

+don't know what you are doing, \fBdon't use them\fR.  These switches are

+documented further in the file wizard.txt.

+.SH EXAMPLES

+.LP

+This example compresses the PPM file foo.ppm with a quality factor of

+60 and saves the output as foo.jpg:

+.IP

+.B cjpeg \-quality

+.I 60 foo.ppm

+.B >

+.I foo.jpg

+.SH HINTS

+Color GIF files are not the ideal input for JPEG; JPEG is really intended for

+compressing full-color (24-bit) images.  In particular, don't try to convert

+cartoons, line drawings, and other images that have only a few distinct

+colors.  GIF works great on these, JPEG does not.  If you want to convert a

+GIF to JPEG, you should experiment with

+.BR cjpeg 's

+.B \-quality

+and

+.B \-smooth

+options to get a satisfactory conversion.

+.B \-smooth 10

+or so is often helpful.

+.PP

+Avoid running an image through a series of JPEG compression/decompression

+cycles.  Image quality loss will accumulate; after ten or so cycles the image

+may be noticeably worse than it was after one cycle.  It's best to use a

+lossless format while manipulating an image, then convert to JPEG format when

+you are ready to file the image away.

+.PP

+The

+.B \-optimize

+option to

+.B cjpeg

+is worth using when you are making a "final" version for posting or archiving.

+It's also a win when you are using low quality settings to make very small

+JPEG files; the percentage improvement is often a lot more than it is on

+larger files.  (At present,

+.B \-optimize

+mode is always selected when generating progressive JPEG files.)

+.SH ENVIRONMENT

+.TP

+.B JPEGMEM

+If this environment variable is set, its value is the default memory limit.

+The value is specified as described for the

+.B \-maxmemory

+switch.

+.B JPEGMEM

+overrides the default value specified when the program was compiled, and

+itself is overridden by an explicit

+.BR \-maxmemory .

+Independent JPEG Group

+.SH BUGS

+(Conversion of GIF files to JPEG is usually a bad idea anyway.)

+Not all variants of BMP and Targa file formats are supported.

+.PP

+The

+.B \-targa

+switch is not a bug, it's a feature.  (It would be a bug if the Targa format

+designers had not been clueless.)

+IJG JPEG LIBRARY:  CODING RULES

+

+Copyright (C) 1991-1996, Thomas G. Lane.

+This file is part of the Independent JPEG Group's software.

+For conditions of distribution and use, see the accompanying README file.

+

+

+Since numerous people will be contributing code and bug fixes, it's important

+to establish a common coding style.  The goal of using similar coding styles

+is much more important than the details of just what that style is.

+

+In general we follow the recommendations of "Recommended C Style and Coding

+Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and

+Brader).  This document is available in the IJG FTP archive (see

+jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl).

+

+Block comments should be laid out thusly:

+

+/*

+ *  Block comments in this style.

+ */

+

+We indent statements in K&R style, e.g.,

+        if (test) {

+          then-part;

+        } else {

+          else-part;

+        }

+with two spaces per indentation level.  (This indentation convention is

+handled automatically by GNU Emacs and many other text editors.)

+

+Multi-word names should be written in lower case with underscores, e.g.,

+multi_word_name (not multiWordName).  Preprocessor symbols and enum constants

+are similar but upper case (MULTI_WORD_NAME).  Names should be unique within

+the first fifteen characters.  (On some older systems, global names must be

+unique within six characters.  We accommodate this without cluttering the

+source code by using macros to substitute shorter names.)

+

+We use function prototypes everywhere; we rely on automatic source code

+transformation to feed prototype-less C compilers.  Transformation is done

+by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).

+ansi2knr is not very bright, so it imposes a format requirement on function

+declarations: the function name MUST BEGIN IN COLUMN 1.  Thus all functions

+should be written in the following style:

+

+LOCAL(int *)

+function_name (int a, char *b)

+{

+    code...

+}

+

+Note that each function definition must begin with GLOBAL(type), LOCAL(type),

+or METHODDEF(type).  These macros expand to "static type" or just "type" as

+appropriate.  They provide a readable indication of the routine's usage and

+can readily be changed for special needs.  (For instance, special linkage

+keywords can be inserted for use in Windows DLLs.)

+

+ansi2knr does not transform method declarations (function pointers in

+structs).  We handle these with a macro JMETHOD, defined as

+        #ifdef HAVE_PROTOTYPES

+        #define JMETHOD(type,methodname,arglist)  type (*methodname) arglist

+        #else

+        #define JMETHOD(type,methodname,arglist)  type (*methodname) ()

+        #endif

+which is used like this:

+        struct function_pointers {

+          JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));

+          JMETHOD(void, term_entropy_encoder, (void));

+        };

+Note the set of parentheses surrounding the parameter list.

+

+A similar solution is used for forward and external function declarations

+(see the EXTERN and JPP macros).

+

+If the code is to work on non-ANSI compilers, we cannot rely on a prototype

+declaration to coerce actual parameters into the right types.  Therefore, use

+explicit casts on actual parameters whenever the actual parameter type is not

+identical to the formal parameter.  Beware of implicit conversions to "int".

+

+It seems there are some non-ANSI compilers in which the sizeof() operator

+is defined to return int, yet size_t is defined as long.  Needless to say,

+this is brain-damaged.  Always use the SIZEOF() macro in place of sizeof(),

+so that the result is guaranteed to be of type size_t.

+

+

+The JPEG library is intended to be used within larger programs.  Furthermore,

+we want it to be reentrant so that it can be used by applications that process

+multiple images concurrently.  The following rules support these requirements:

+

+1. Avoid direct use of file I/O, "malloc", error report printouts, etc;

+pass these through the common routines provided.

+

+2. Minimize global namespace pollution.  Functions should be declared static

+wherever possible.  (Note that our method-based calling conventions help this

+a lot: in many modules only the initialization function will ever need to be

+called directly, so only that function need be externally visible.)  All

+global function names should begin with "jpeg_", and should have an

+abbreviated name (unique in the first six characters) substituted by macro

+when NEED_SHORT_EXTERNAL_NAMES is set.

+

+3. Don't use global variables; anything that must be used in another module

+should be in the common data structures.

+

+4. Don't use static variables except for read-only constant tables.  Variables

+that should be private to a module can be placed into private structures (see

+the system architecture document, structure.txt).

+

+5. Source file names should begin with "j" for files that are part of the

+library proper; source files that are not part of the library, such as cjpeg.c

+and djpeg.c, do not begin with "j".  Keep source file names to eight

+characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers.  Keep

+compression and decompression code in separate source files --- some

+applications may want only one half of the library.

+

+Note: these rules (particularly #4) are not followed religiously in the

+modules that are used in cjpeg/djpeg but are not part of the JPEG library

+proper.  Those modules are not really intended to be used in other

+applications.

+\`configure' configures libjpeg 8.4.0 to adapt to many kinds of systems.

+

+Usage: $0 [OPTION]... [VAR=VALUE]...

+

+To assign environment variables (e.g., CC, CFLAGS...), specify them as

+VAR=VALUE.  See below for descriptions of some of the useful variables.

+

+Defaults for the options are specified in brackets.

+

+Configuration:

+  -h, --help              display this help and exit

+      --help=short        display options specific to this package

+      --help=recursive    display the short help of all the included packages

+  -V, --version           display version information and exit

+  -q, --quiet, --silent   do not print \`checking ...' messages

+      --cache-file=FILE   cache test results in FILE [disabled]

+  -C, --config-cache      alias for \`--cache-file=config.cache'

+  -n, --no-create         do not create output files

+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+

+Installation directories:

+  --prefix=PREFIX         install architecture-independent files in PREFIX

+                          [$ac_default_prefix]

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX

+                          [PREFIX]

+

+By default, \`make install' will install all the files in

+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify

+an installation prefix other than \`$ac_default_prefix' using \`--prefix',

+for instance \`--prefix=\$HOME'.

+

+For better control, use the options below.

+

+Fine tuning of the installation directories:

+  --bindir=DIR            user executables [EPREFIX/bin]

+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]

+  --libdir=DIR            object code libraries [EPREFIX/lib]

+  --includedir=DIR        C header files [PREFIX/include]

+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]

+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

+  --infodir=DIR           info documentation [DATAROOTDIR/info]

+  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

+  --enable-silent-rules          less verbose build output (undo: `make V=1')

+  --disable-silent-rules         verbose build output (undo: `make V=0')

+  --disable-dependency-tracking  speeds up one-time build

+  --enable-dependency-tracking   do not reject slow dependency extractors

+  --enable-maintainer-mode  enable make rules and dependencies not useful

+                          (and sometimes confusing) to the casual installer

+  --enable-ld-version-script

+                          enable linker version script (default is enabled

+                          when possible)

+  --enable-shared[=PKGS]  build shared libraries [default=yes]

+  --enable-static[=PKGS]  build static libraries [default=yes]

+  --enable-fast-install[=PKGS]

+                          optimize for fast installation [default=yes]

+  --disable-libtool-lock  avoid locking (might break parallel builds)

+  --enable-maxmem=N     enable use of temp files, set max mem usage to N MB

+

+Optional Packages:

+  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]

+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)

+  --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use

+                          both]

+  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]

+  --with-sysroot=DIR Search for dependent libraries within DIR

+                        (or the compiler's sysroot if not specified).

+

+Some influential environment variables:

+  CC          C compiler command

+  CFLAGS      C compiler flags

+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+              nonstandard directory <lib dir>

+  LIBS        libraries to pass to the linker, e.g. -l<library>

+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

+              you have headers in a nonstandard directory <include dir>

+  CPP         C preprocessor

+

+Use these variables to override the choices made by `configure' or to help

+it to find libraries and programs with nonstandard names/locations.

+

+Report bugs to the package provider.

+.SH NAME

+djpeg \- decompress a JPEG file to an image file

+.SH SYNOPSIS

+.B djpeg

+[

+.I options

+]

+[

+.I filename

+]

+.LP

+.SH DESCRIPTION

+.LP

+.B djpeg

+decompresses the named JPEG file, or the standard input if no file is named,

+and produces an image file on the standard output.  PBMPLUS (PPM/PGM), BMP,

+GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected.

+(RLE is supported only if the URT library is available.)

+.SH OPTIONS

+All switch names may be abbreviated; for example,

+.B \-grayscale

+may be written

+.B \-gray

+or

+.BR \-gr .

+Most of the "basic" switches can be abbreviated to as little as one letter.

+Upper and lower case are equivalent (thus

+.B \-BMP

+is the same as

+.BR \-bmp ).

+British spellings are also accepted (e.g.,

+.BR \-greyscale ),

+though for brevity these are not mentioned below.

+.PP

+The basic switches are:

+.TP

+.BI \-colors " N"

+Reduce image to at most N colors.  This reduces the number of colors used in

+the output image, so that it can be displayed on a colormapped display or

+stored in a colormapped file format.  For example, if you have an 8-bit

+display, you'd need to reduce to 256 or fewer colors.

+.TP

+.BI \-quantize " N"

+Same as

+.BR \-colors .

+.B \-colors

+is the recommended name,

+.B \-quantize

+is provided only for backwards compatibility.

+.TP

+.B \-fast

+Select recommended processing options for fast, low quality output.  (The

+default options are chosen for highest quality output.)  Currently, this is

+equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR.

+.TP

+.B \-grayscale

+Force gray-scale output even if JPEG file is color.  Useful for viewing on

+monochrome displays; also,

+.B djpeg

+runs noticeably faster in this mode.

+.TP

+.BI \-scale " M/N"

+Scale the output image by a factor M/N.  Currently supported scale factors are

+M/N with all M from 1 to 16, where N is the source DCT size, which is 8 for

+baseline JPEG.  If the /N part is omitted, then M specifies the DCT scaled

+size to be applied on the given input.  For baseline JPEG this is equivalent

+to M/8 scaling, since the source DCT size for baseline JPEG is 8.

+Scaling is handy if the image is larger than your screen; also,

+.B djpeg

+runs much faster when scaling down the output.

+.TP

+.B \-bmp

+Select BMP output format (Windows flavor).  8-bit colormapped format is

+emitted if

+.B \-colors

+or

+.B \-grayscale

+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color

+format is emitted.

+.TP

+.B \-gif

+Select GIF output format.  Since GIF does not support more than 256 colors,

+.B \-colors 256

+is assumed (unless you specify a smaller number of colors).

+.TP

+.B \-os2

+Select BMP output format (OS/2 1.x flavor).  8-bit colormapped format is

+emitted if

+.B \-colors

+or

+.B \-grayscale

+is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color

+format is emitted.

+.TP

+.B \-pnm

+Select PBMPLUS (PPM/PGM) output format (this is the default format).

+PGM is emitted if the JPEG file is gray-scale or if

+.B \-grayscale

+is specified; otherwise PPM is emitted.

+.TP

+.B \-rle

+Select RLE output format.  (Requires URT library.)

+.TP

+.B \-targa

+Select Targa output format.  Gray-scale format is emitted if the JPEG file is

+gray-scale or if

+.B \-grayscale

+is specified; otherwise, colormapped format is emitted if

+.B \-colors

+is specified; otherwise, 24-bit full-color format is emitted.

+.PP

+Switches for advanced users:

+.TP

+.B \-dct int

+Use integer DCT method (default).

+.TP

+.B \-dct fast

+Use fast integer DCT (less accurate).

+.TP

+.B \-dct float

+Use floating-point DCT method.

+The float method is very slightly more accurate than the int method, but is

+much slower unless your machine has very fast floating-point hardware.  Also

+note that results of the floating-point method may vary slightly across

+machines, while the integer methods should give the same results everywhere.

+The fast integer method is much less accurate than the other two.

+.TP

+.B \-dither fs

+Use Floyd-Steinberg dithering in color quantization.

+.TP

+.B \-dither ordered

+Use ordered dithering in color quantization.

+.TP

+.B \-dither none

+Do not use dithering in color quantization.

+By default, Floyd-Steinberg dithering is applied when quantizing colors; this

+is slow but usually produces the best results.  Ordered dither is a compromise

+between speed and quality; no dithering is fast but usually looks awful.  Note

+that these switches have no effect unless color quantization is being done.

+Ordered dither is only available in

+.B \-onepass

+mode.

+.TP

+.BI \-map " file"

+Quantize to the colors used in the specified image file.  This is useful for

+producing multiple files with identical color maps, or for forcing a

+predefined set of colors to be used.  The

+.I file

+must be a GIF or PPM file. This option overrides

+.B \-colors

+and

+.BR \-onepass .

+.TP

+.B \-nosmooth

+Don't use high-quality upsampling.

+.TP

+.B \-onepass

+Use one-pass instead of two-pass color quantization.  The one-pass method is

+faster and needs less memory, but it produces a lower-quality image.

+.B \-onepass

+is ignored unless you also say

+.B \-colors

+.IR N .

+Also, the one-pass method is always used for gray-scale output (the two-pass

+method is no improvement then).

+.TP

+.BI \-maxmemory " N"

+Set limit for amount of memory to use in processing large images.  Value is

+in thousands of bytes, or millions of bytes if "M" is attached to the

+number.  For example,

+.B \-max 4m

+selects 4000000 bytes.  If more space is needed, temporary files will be used.

+.TP

+.BI \-outfile " name"

+Send output image to the named file, not to standard output.

+.TP

+.B \-verbose

+Enable debug printout.  More

+.BR \-v 's

+give more output.  Also, version information is printed at startup.

+.TP

+.B \-debug

+Same as

+.BR \-verbose .

+.SH EXAMPLES

+.LP

+This example decompresses the JPEG file foo.jpg, quantizes it to

+256 colors, and saves the output in 8-bit BMP format in foo.bmp:

+.IP

+.B djpeg \-colors 256 \-bmp

+.I foo.jpg

+.B >

+.I foo.bmp

+.SH HINTS

+To get a quick preview of an image, use the

+.B \-grayscale

+and/or

+.B \-scale

+switches.

+.B \-grayscale \-scale 1/8

+is the fastest case.

+.PP

+Several options are available that trade off image quality to gain speed.

+.B \-fast

+turns on the recommended settings.

+.PP

+.B \-dct fast

+and/or

+.B \-nosmooth

+gain speed at a small sacrifice in quality.

+When producing a color-quantized image,

+.B \-onepass \-dither ordered

+is fast but much lower quality than the default behavior.

+.B \-dither none

+may give acceptable results in two-pass mode, but is seldom tolerable in

+one-pass mode.

+.PP

+If you are fortunate enough to have very fast floating point hardware,

+\fB\-dct float\fR may be even faster than \fB\-dct fast\fR.  But on most

+machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is

+not worth using, because its theoretical accuracy advantage is too small to be

+significant in practice.

+.SH ENVIRONMENT

+.TP

+.B JPEGMEM

+If this environment variable is set, its value is the default memory limit.

+The value is specified as described for the

+.B \-maxmemory

+switch.

+.B JPEGMEM

+overrides the default value specified when the program was compiled, and

+itself is overridden by an explicit

+.BR \-maxmemory .

+ *      djpeg [options]  inputfile outputfile

+ *      djpeg [options]  [inputfile]

+ * In the second style, output is always to standard output, which you'd

+ * normally redirect to a file or pipe to some other program.  Input is

+ * either from a named file or from standard input (typically redirected).

+ * The second style is convenient on Unix but is unhelpful on systems that

+ * don't support pipes.  Also, you MUST use the first style if your system

+ * doesn't do binary I/O to stdin/stdout.

+ * To simplify script writing, the "-outfile" switch is provided.  The syntax

+ *      djpeg [options]  -outfile outputfile  inputfile

+ * error_exit routine.  To do this, we make a private extension of the

+ * standard JPEG error handler object.  (If we were using C++, we'd say we

+IJG JPEG LIBRARY:  FILE LIST

+

+Copyright (C) 1994-2009, Thomas G. Lane, Guido Vollbeding.

+This file is part of the Independent JPEG Group's software.

+For conditions of distribution and use, see the accompanying README file.

+

+

+Here is a road map to the files in the IJG JPEG distribution.  The

+distribution includes the JPEG library proper, plus two application

+programs ("cjpeg" and "djpeg") which use the library to convert JPEG

+files to and from some other popular image formats.  A third application

+"jpegtran" uses the library to do lossless conversion between different

+variants of JPEG.  There are also two stand-alone applications,

+"rdjpgcom" and "wrjpgcom".

+

+

+THE JPEG LIBRARY

+================

+

+Include files:

+

+jpeglib.h       JPEG library's exported data and function declarations.

+jconfig.h       Configuration declarations.  Note: this file is not present

+                in the distribution; it is generated during installation.

+jmorecfg.h      Additional configuration declarations; need not be changed

+                for a standard installation.

+jerror.h        Declares JPEG library's error and trace message codes.

+jinclude.h      Central include file used by all IJG .c files to reference

+                system include files.

+jpegint.h       JPEG library's internal data structures.

+jdct.h          Private declarations for forward & reverse DCT subsystems.

+jmemsys.h       Private declarations for memory management subsystem.

+jversion.h      Version information.

+

+Applications using the library should include jpeglib.h (which in turn

+includes jconfig.h and jmorecfg.h).  Optionally, jerror.h may be included

+if the application needs to reference individual JPEG error codes.  The

+other include files are intended for internal use and would not normally

+be included by an application program.  (cjpeg/djpeg/etc do use jinclude.h,

+since its function is to improve portability of the whole IJG distribution.

+Most other applications will directly include the system include files they

+want, and hence won't need jinclude.h.)

+

+

+C source code files:

+

+These files contain most of the functions intended to be called directly by

+an application program:

+

+jcapimin.c      Application program interface: core routines for compression.

+jcapistd.c      Application program interface: standard compression.

+jdapimin.c      Application program interface: core routines for decompression.

+jdapistd.c      Application program interface: standard decompression.

+jcomapi.c       Application program interface routines common to compression

+                and decompression.

+jcparam.c       Compression parameter setting helper routines.

+jctrans.c       API and library routines for transcoding compression.

+jdtrans.c       API and library routines for transcoding decompression.

+

+Compression side of the library:

+

+jcinit.c        Initialization: determines which other modules to use.

+jcmaster.c      Master control: setup and inter-pass sequencing logic.

+jcmainct.c      Main buffer controller (preprocessor => JPEG compressor).

+jcprepct.c      Preprocessor buffer controller.

+jccoefct.c      Buffer controller for DCT coefficient buffer.

+jccolor.c       Color space conversion.

+jcsample.c      Downsampling.

+jcdctmgr.c      DCT manager (DCT implementation selection & control).

+jfdctint.c      Forward DCT using slow-but-accurate integer method.

+jfdctfst.c      Forward DCT using faster, less accurate integer method.

+jfdctflt.c      Forward DCT using floating-point arithmetic.

+jchuff.c        Huffman entropy coding.

+jcarith.c       Arithmetic entropy coding.

+jcmarker.c      JPEG marker writing.

+jdatadst.c      Data destination managers for memory and stdio output.

+

+Decompression side of the library:

+

+jdmaster.c      Master control: determines which other modules to use.

+jdinput.c       Input controller: controls input processing modules.

+jdmainct.c      Main buffer controller (JPEG decompressor => postprocessor).

+jdcoefct.c      Buffer controller for DCT coefficient buffer.

+jdpostct.c      Postprocessor buffer controller.

+jdmarker.c      JPEG marker reading.

+jdhuff.c        Huffman entropy decoding.

+jdarith.c       Arithmetic entropy decoding.

+jddctmgr.c      IDCT manager (IDCT implementation selection & control).

+jidctint.c      Inverse DCT using slow-but-accurate integer method.

+jidctfst.c      Inverse DCT using faster, less accurate integer method.

+jidctflt.c      Inverse DCT using floating-point arithmetic.

+jdsample.c      Upsampling.

+jdcolor.c       Color space conversion.

+jdmerge.c       Merged upsampling/color conversion (faster, lower quality).

+jquant1.c       One-pass color quantization using a fixed-spacing colormap.

+jquant2.c       Two-pass color quantization using a custom-generated colormap.

+                Also handles one-pass quantization to an externally given map.

+jdatasrc.c      Data source managers for memory and stdio input.

+

+Support files for both compression and decompression:

+

+jaricom.c       Tables for common use in arithmetic entropy encoding and

+                decoding routines.

+jerror.c        Standard error handling routines (application replaceable).

+jmemmgr.c       System-independent (more or less) memory management code.

+jutils.c        Miscellaneous utility routines.

+

+jmemmgr.c relies on a system-dependent memory management module.  The IJG

+distribution includes the following implementations of the system-dependent

+module:

+

+jmemnobs.c      "No backing store": assumes adequate virtual memory exists.

+jmemansi.c      Makes temporary files with ANSI-standard routine tmpfile().

+jmemname.c      Makes temporary files with program-generated file names.

+jmemdos.c       Custom implementation for MS-DOS (16-bit environment only):

+                can use extended and expanded memory as well as temp files.

+jmemmac.c       Custom implementation for Apple Macintosh.

+

+Exactly one of the system-dependent modules should be configured into an

+installed JPEG library (see install.txt for hints about which one to use).

+On unusual systems you may find it worthwhile to make a special

+system-dependent memory manager.

+

+

+INSTALLATION INSTRUCTIONS for the Independent JPEG Group's JPEG software

+

+Copyright (C) 1991-2011, Thomas G. Lane, Guido Vollbeding.

+This file is part of the Independent JPEG Group's software.

+For conditions of distribution and use, see the accompanying README file.

+

+

+This file explains how to configure and install the IJG software.  We have

+tried to make this software extremely portable and flexible, so that it can be

+adapted to almost any environment.  The downside of this decision is that the

+installation process is complicated.  We have provided shortcuts to simplify

+the task on common systems.  But in any case, you will need at least a little

+familiarity with C programming and program build procedures for your system.

+

+If you are only using this software as part of a larger program, the larger

+program's installation procedure may take care of configuring the IJG code.

+For example, Ghostscript's installation script will configure the IJG code.

+You don't need to read this file if you just want to compile Ghostscript.

+

+If you are on a Unix machine, you may not need to read this file at all.

+Try doing

+        ./configure

+        make

+        make test

+If that doesn't complain, do

+        make install

+(better do "make -n install" first to see if the makefile will put the files

+where you want them).  Read further if you run into snags or want to customize

+the code for your system.

+

+

+BEFORE YOU START

+================

+

+Before installing the software you must unpack the distributed source code.

+Since you are reading this file, you have probably already succeeded in this

+task.  However, there is a potential for error if you needed to convert the

+files to the local standard text file format (for example, if you are on

+MS-DOS you may have converted LF end-of-line to CR/LF).  You must apply

+such conversion to all the files EXCEPT those whose names begin with "test".

+The test files contain binary data; if you change them in any way then the

+self-test will give bad results.

+

+Please check the last section of this file to see if there are hints for the

+specific machine or compiler you are using.

+

+

+CONFIGURING THE SOFTWARE

+========================

+

+To configure the IJG code for your system, you need to create two files:

+  * jconfig.h: contains values for system-dependent #define symbols.

+  * Makefile: controls the compilation process.

+(On a non-Unix machine, you may create "project files" or some other

+substitute for a Makefile.  jconfig.h is needed in any environment.)

+

+We provide three different ways to generate these files:

+  * On a Unix system, you can just run the "configure" script.

+  * We provide sample jconfig files and makefiles for popular machines;

+    if your machine matches one of the samples, just copy the right sample

+    files to jconfig.h and Makefile.

+  * If all else fails, read the instructions below and make your own files.

+

+

+Configuring the software using the automatic "configure" script

+---------------------------------------------------------------

+

+If you are on a Unix machine, you can just type

+        ./configure

+and let the configure script construct appropriate configuration files.

+If you're using "csh" on an old version of System V, you might need to type

+        sh configure

+instead to prevent csh from trying to execute configure itself.

+Expect configure to run for a few minutes, particularly on slower machines;

+it works by compiling a series of test programs.

+

+Configure was created with GNU Autoconf and it follows the usual conventions

+for GNU configure scripts.  It makes a few assumptions that you may want to

+override.  You can do this by providing optional switches to configure:

+

+* Configure will build both static and shared libraries, if possible.

+If you want to build libjpeg only as a static library, say

+        ./configure --disable-shared

+If you want to build libjpeg only as a shared library, say

+        ./configure --disable-static

+Configure uses GNU libtool to take care of system-dependent shared library

+building methods.

+

+* Configure will use gcc (GNU C compiler) if it's available, otherwise cc.

+To force a particular compiler to be selected, use the CC option, for example

+        ./configure CC='cc'

+The same method can be used to include any unusual compiler switches.

+For example, on HP-UX you probably want to say

+        ./configure CC='cc -Aa'

+to get HP's compiler to run in ANSI mode.

+

+* The default CFLAGS setting is "-g" for non-gcc compilers, "-g -O2" for gcc.

+You can override this by saying, for example,

+        ./configure CFLAGS='-O2'

+if you want to compile without debugging support.

+

+* Configure will set up the makefile so that "make install" will install files

+into /usr/local/bin, /usr/local/man, etc.  You can specify an installation

+prefix other than "/usr/local" by giving configure the option "--prefix=PATH".

+

+* If you don't have a lot of swap space, you may need to enable the IJG

+software's internal virtual memory mechanism.  To do this, give the option

+"--enable-maxmem=N" where N is the default maxmemory limit in megabytes.

+This is discussed in more detail under "Selecting a memory manager", below.

+You probably don't need to worry about this on reasonably-sized Unix machines,

+unless you plan to process very large images.

+

+Configure has some other features that are useful if you are cross-compiling

+or working in a network of multiple machine types; but if you need those

+features, you probably already know how to use them.

+

+

+Configuring the software using one of the supplied jconfig and makefile files

+-----------------------------------------------------------------------------

+

+If you have one of these systems, you can just use the provided configuration

+files:

+

+Makefile        jconfig file    System and/or compiler

+

+makefile.manx   jconfig.manx    Amiga, Manx Aztec C

+makefile.sas    jconfig.sas     Amiga, SAS C

+makeproj.mac    jconfig.mac     Apple Macintosh, Metrowerks CodeWarrior

+mak*jpeg.st     jconfig.st      Atari ST/STE/TT, Pure C or Turbo C

+makefile.bcc    jconfig.bcc     MS-DOS or OS/2, Borland C

+makefile.dj     jconfig.dj      MS-DOS, DJGPP (Delorie's port of GNU C)

+makefile.mc6    jconfig.mc6     MS-DOS, Microsoft C (16-bit only)

+makefile.wat    jconfig.wat     MS-DOS, OS/2, or Windows NT, Watcom C

+makefile.vc     jconfig.vc      Windows NT/95, MS Visual C++

+make*.vc6       jconfig.vc      Windows NT/95, MS Visual C++ 6

+make*.v10       jconfig.vc      Windows NT/95, MS Visual C++ 2010 (v10)

+makefile.mms    jconfig.vms     Digital VMS, with MMS software

+makefile.vms    jconfig.vms     Digital VMS, without MMS software

+

+Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or

+whatever your system uses as the standard makefile name).  For more info see

+the appropriate system-specific hints section near the end of this file.

+

+

+Configuring the software by hand

+--------------------------------

+

+First, generate a jconfig.h file.  If you are moderately familiar with C,

+the comments in jconfig.txt should be enough information to do this; just

+copy jconfig.txt to jconfig.h and edit it appropriately.  Otherwise, you may

+prefer to use the ckconfig.c program.  You will need to compile and execute

+ckconfig.c by hand --- we hope you know at least enough to do that.

+ckconfig.c may not compile the first try (in fact, the whole idea is for it

+to fail if anything is going to).  If you get compile errors, fix them by

+editing ckconfig.c according to the directions given in ckconfig.c.  Once

+you get it to run, it will write a suitable jconfig.h file, and will also

+print out some advice about which makefile to use.

+

+You may also want to look at the canned jconfig files, if there is one for a

+system similar to yours.

+

+Second, select a makefile and copy it to Makefile (or whatever your system

+uses as the standard makefile name).  The most generic makefiles we provide

+are

+        makefile.ansi:  if your C compiler supports function prototypes

+        makefile.unix:  if not.

+(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES"

+in jconfig.h.)  You may want to start from one of the other makefiles if

+there is one for a system similar to yours.

+

+Look over the selected Makefile and adjust options as needed.  In particular

+you may want to change the CC and CFLAGS definitions.  For instance, if you

+are using GCC, set CC=gcc.  If you had to use any compiler switches to get

+ckconfig.c to work, make sure the same switches are in CFLAGS.

+

+If you are on a system that doesn't use makefiles, you'll need to set up

+project files (or whatever you do use) to compile all the source files and

+link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom.

+See the file lists in any of the makefiles to find out which files go into

+each program.  Note that the provided makefiles all make a "library" file

+libjpeg first, but you don't have to do that if you don't want to; the file

+lists identify which source files are actually needed for compression,

+decompression, or both.  As a last resort, you can make a batch script that

+just compiles everything and links it all together; makefile.vms is an example

+of this (it's for VMS systems that have no make-like utility).

+

+Here are comments about some specific configuration decisions you'll

+need to make:

+

+Command line style

+------------------

+

+These programs can use a Unix-like command line style which supports

+redirection and piping, like this:

+        cjpeg inputfile >outputfile

+        cjpeg <inputfile >outputfile

+        source program | cjpeg >outputfile

+The simpler "two file" command line style is just

+        cjpeg inputfile outputfile

+You may prefer the two-file style, particularly if you don't have pipes.

+

+You MUST use two-file style on any system that doesn't cope well with binary

+data fed through stdin/stdout; this is true for some MS-DOS compilers, for

+example.  If you're not on a Unix system, it's safest to assume you need

+two-file style.  (But if your compiler provides either the Posix-standard

+fdopen() library routine or a Microsoft-compatible setmode() routine, you

+can safely use the Unix command line style, by defining USE_FDOPEN or

+USE_SETMODE respectively.)

+

+To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE".

+

+Selecting a memory manager

+--------------------------

+

+The IJG code is capable of working on images that are too big to fit in main

+memory; data is swapped out to temporary files as necessary.  However, the

+code to do this is rather system-dependent.  We provide five different

+memory managers:

+

+* jmemansi.c    This version uses the ANSI-standard library routine tmpfile(),

+                which not all non-ANSI systems have.  On some systems

+                tmpfile() may put the temporary file in a non-optimal

+                location; if you don't like what it does, use jmemname.c.

+

+* jmemname.c    This version creates named temporary files.  For anything

+                except a Unix machine, you'll need to configure the

+                select_file_name() routine appropriately; see the comments

+                near the head of jmemname.c.  If you use this version, define

+                NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files

+                are removed if the program is aborted.

+

+* jmemnobs.c    (That stands for No Backing Store :-).)  This will compile on

+                almost any system, but it assumes you have enough main memory

+                or virtual memory to hold the biggest images you work with.

+

+* jmemdos.c     This should be used with most 16-bit MS-DOS compilers.

+                See the system-specific notes about MS-DOS for more info.

+                IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in

+                jconfig.h, and include the assembly file jmemdosa.asm in the

+                programs.  The supplied makefiles and jconfig files for

+                16-bit MS-DOS compilers already do both.

+

+* jmemmac.c     Custom version for Apple Macintosh; see the system-specific

+                notes for Macintosh for more info.

+

+To use a particular memory manager, change the SYSDEPMEM variable in your

+makefile to equal the corresponding object file name (for example, jmemansi.o

+or jmemansi.obj for jmemansi.c).

+

+If you have plenty of (real or virtual) main memory, just use jmemnobs.c.

+"Plenty" means about ten bytes for every pixel in the largest images

+you plan to process, so a lot of systems don't meet this criterion.

+If yours doesn't, try jmemansi.c first.  If that doesn't compile, you'll have

+to use jmemname.c; be sure to adjust select_file_name() for local conditions.

+You may also need to change unlink() to remove() in close_backing_store().

+

+Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM

+setting to a reasonable value for your system (either by adding a #define for

+DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile).

+This value limits the amount of data space the program will attempt to

+allocate.  Code and static data space isn't counted, so the actual memory

+needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory

+setting.  Larger max-memory settings reduce the amount of I/O needed to

+process a large image, but too large a value can result in "insufficient

+memory" failures.  On most Unix machines (and other systems with virtual

+memory), just set DEFAULT_MAX_MEM to several million and forget it.  At the

+other end of the spectrum, for MS-DOS machines you probably can't go much

+above 300K to 400K.  (On MS-DOS the value refers to conventional memory only.

+Extended/expanded memory is handled separately by jmemdos.c.)

+

+

+BUILDING THE SOFTWARE

+=====================

+

+Now you should be able to compile the software.  Just say "make" (or

+whatever's necessary to start the compilation).  Have a cup of coffee.

+

+Here are some things that could go wrong:

+

+If your compiler complains about undefined structures, you should be able to

+shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h.

+

+If you have trouble with missing system include files or inclusion of the

+wrong ones, read jinclude.h.  This shouldn't happen if you used configure

+or ckconfig.c to set up jconfig.h.

+

+There are a fair number of routines that do not use all of their parameters;

+some compilers will issue warnings about this, which you can ignore.  There

+are also a few configuration checks that may give "unreachable code" warnings.

+Any other warning deserves investigation.

+

+If you don't have a getenv() library routine, define NO_GETENV.

+

+Also see the system-specific hints, below.

+

+

+TESTING THE SOFTWARE

+====================

+

+As a quick test of functionality we've included a small sample image in

+several forms:

+        testorig.jpg    Starting point for the djpeg tests.

+        testimg.ppm     The output of djpeg testorig.jpg

+        testimg.bmp     The output of djpeg -bmp -colors 256 testorig.jpg

+        testimg.jpg     The output of cjpeg testimg.ppm

+        testprog.jpg    Progressive-mode equivalent of testorig.jpg.

+        testimgp.jpg    The output of cjpeg -progressive -optimize testimg.ppm

+(The first- and second-generation .jpg files aren't identical since the

+default compression parameters are lossy.)  If you can generate duplicates

+of the testimg* files then you probably have working programs.

+

+With most of the makefiles, "make test" will perform the necessary

+comparisons.

+

+If you're using a makefile that doesn't provide the test option, run djpeg

+and cjpeg by hand and compare the output files to testimg* with whatever

+binary file comparison tool you have.  The files should be bit-for-bit

+identical.

+

+If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you

+need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t.

+Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h.  A less likely

+configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE

+as long should take care of that one.

+

+If the cjpeg test run fails with "Missing Huffman code table entry", it's a

+good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED.  Go back to the

+configuration step and run ckconfig.c.  (This is a good plan for any other

+test failure, too.)

+

+If you are using Unix (one-file) command line style on a non-Unix system,

+it's a good idea to check that binary I/O through stdin/stdout actually

+works.  You should get the same results from "djpeg <testorig.jpg >out.ppm"

+as from "djpeg -outfile out.ppm testorig.jpg".  Note that the makefiles all

+use the latter style and therefore do not exercise stdin/stdout!  If this

+check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined.

+If it still doesn't work, better use two-file style.

+

+If you chose a memory manager other than jmemnobs.c, you should test that

+temporary-file usage works.  Try "djpeg -bmp -colors 256 -max 0 testorig.jpg"

+and make sure its output matches testimg.bmp.  If you have any really large

+images handy, try compressing them with -optimize and/or decompressing with

+-colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large.

+

+NOTE: this is far from an exhaustive test of the JPEG software; some modules,

+such as 1-pass color quantization, are not exercised at all.  It's just a

+quick test to give you some confidence that you haven't missed something

+major.

+

+

+INSTALLING THE SOFTWARE

+=======================

+

+Once you're done with the above steps, you can install the software by

+copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom)

+to wherever you normally install programs.  On Unix systems, you'll also want

+to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1)

+in the man-page directory.  The pre-fab makefiles don't support this step

+since there's such a wide variety of installation procedures on different

+systems.

+

+If you generated a Makefile with the "configure" script, you can just say

+        make install

+to install the programs and their man pages into the standard places.

+(You'll probably need to be root to do this.)  We recommend first saying

+        make -n install

+to see where configure thought the files should go.  You may need to edit

+the Makefile, particularly if your system's conventions for man page

+filenames don't match what configure expects.

+

+If you want to install the IJG library itself, for use in compiling other

+programs besides ours, then you need to put the four include files

+        jpeglib.h jerror.h jconfig.h jmorecfg.h

+into your include-file directory, and put the library file libjpeg.a

+(extension may vary depending on system) wherever library files go.

+If you generated a Makefile with "configure", it will do what it thinks

+is the right thing if you say

+        make install-lib

+

+

+OPTIONAL STUFF

+==============

+

+Progress monitor:

+

+If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display

+of percent-done progress reports.  The routine provided in cdjpeg.c merely

+prints percentages to stderr, but you can customize it to do something

+fancier.

+

+Utah RLE file format support:

+

+We distribute the software with support for RLE image files (Utah Raster

+Toolkit format) disabled, because the RLE support won't compile without the

+Utah library.  If you have URT version 3.1 or later, you can enable RLE

+support as follows:

+        1.  #define RLE_SUPPORTED in jconfig.h.

+        2.  Add a -I option to CFLAGS in the Makefile for the directory

+            containing the URT .h files (typically the "include"

+            subdirectory of the URT distribution).

+        3.  Add -L... -lrle to LDLIBS in the Makefile, where ... specifies

+            the directory containing the URT "librle.a" file (typically the

+            "lib" subdirectory of the URT distribution).

+

+Support for 12-bit-deep pixel data:

+

+The JPEG standard allows either 8-bit or 12-bit data precision.  (For color,

+this means 8 or 12 bits per channel, of course.)  If you need to work with

+deeper than 8-bit data, you can compile the IJG code for 12-bit operation.

+To do so:

+  1. In jmorecfg.h, define BITS_IN_JSAMPLE as 12 rather than 8.

+  2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED,

+     because the code for those formats doesn't handle 12-bit data and won't

+     even compile.  (The PPM code does work, as explained below.  The GIF

+     code works too; it scales 8-bit GIF data to and from 12-bit depth

+     automatically.)

+  3. Compile.  Don't expect "make test" to pass, since the supplied test

+     files are for 8-bit data.

+

+Currently, 12-bit support does not work on 16-bit-int machines.

+

+Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa;

+so you'll want to keep around a regular 8-bit compilation as well.

+(Run-time selection of data depth, to allow a single copy that does both,

+is possible but would probably slow things down considerably; it's very low

+on our to-do list.)

+

+The PPM reader (rdppm.c) can read 12-bit data from either text-format or

+binary-format PPM and PGM files.  Binary-format PPM/PGM files which have a

+maxval greater than 255 are assumed to use 2 bytes per sample, MSB first

+(big-endian order).  As of early 1995, 2-byte binary format is not

+officially supported by the PBMPLUS library, but it is expected that a

+future release of PBMPLUS will support it.  Note that the PPM reader will

+read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming

+data is automatically rescaled to either maxval=255 or maxval=4095 as

+appropriate for the cjpeg bit depth.

+

+The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM

+format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12.  Since this

+format is not yet widely supported, you can disable it by compiling wrppm.c

+with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a

+standard 1-byte/sample PPM or PGM file.  (Yes, this means still another copy

+of djpeg to keep around.  But hopefully you won't need it for very long.

+Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.)

+

+Of course, if you are working with 12-bit data, you probably have it stored

+in some other, nonstandard format.  In that case you'll probably want to

+write your own I/O modules to read and write your format.

+

+Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in

+order to generate valid Huffman tables.  This is necessary because our

+default Huffman tables only cover 8-bit data.

+

+Removing code:

+

+If you need to make a smaller version of the JPEG software, some optional

+functions can be removed at compile time.  See the xxx_SUPPORTED #defines in

+jconfig.h and jmorecfg.h.  If at all possible, we recommend that you leave in

+decoder support for all valid JPEG files, to ensure that you can read anyone's

+output.  Taking out support for image file formats that you don't use is the

+most painless way to make the programs smaller.  Another possibility is to

+remove some of the DCT methods: in particular, the "IFAST" method may not be

+enough faster than the others to be worth keeping on your machine.  (If you

+do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST

+to a supported method, by adding a #define in jconfig.h.)

+

+

+OPTIMIZATION

+============

+

+Unless you own a Cray, you'll probably be interested in making the JPEG

+software go as fast as possible.  This section covers some machine-dependent

+optimizations you may want to try.  We suggest that before trying any of

+this, you first get the basic installation to pass the self-test step.

+Repeat the self-test after any optimization to make sure that you haven't

+broken anything.

+

+The integer DCT routines perform a lot of multiplications.  These

+multiplications must yield 32-bit results, but none of their input values

+are more than 16 bits wide.  On many machines, notably the 680x0 and 80x86

+CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32

+bit multiply.  Unfortunately there is no portable way to specify such a

+multiplication in C, but some compilers can generate one when you use the

+right combination of casts.  See the MULTIPLYxxx macro definitions in

+jdct.h.  If your compiler makes "int" be 32 bits and "short" be 16 bits,

+defining SHORTxSHORT_32 is fairly likely to work.  When experimenting with

+alternate definitions, be sure to test not only whether the code still works

+(use the self-test), but also whether it is actually faster --- on some

+compilers, alternate definitions may compute the right answer, yet be slower

+than the default.  Timing cjpeg on a large PGM (grayscale) input file is the

+best way to check this, as the DCT will be the largest fraction of the runtime

+in that mode.  (Note: some of the distributed compiler-specific jconfig files

+already contain #define switches to select appropriate MULTIPLYxxx

+definitions.)

+

+If your machine has sufficiently fast floating point hardware, you may find

+that the float DCT method is faster than the integer DCT methods, even

+after tweaking the integer multiply macros.  In that case you may want to

+make the float DCT be the default method.  (The only objection to this is

+that float DCT results may vary slightly across machines.)  To do that, add

+"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h.  Even if you don't change

+the default, you should redefine JDCT_FASTEST, which is the method selected

+by djpeg's -fast switch.  Don't forget to update the documentation files

+(usage.txt and/or cjpeg.1, djpeg.1) to agree with what you've done.

+

+If access to "short" arrays is slow on your machine, it may be a win to

+define type JCOEF as int rather than short.  This will cost a good deal of

+memory though, particularly in some multi-pass modes, so don't do it unless

+you have memory to burn and short is REALLY slow.

+

+If your compiler can compile function calls in-line, make sure the INLINE

+macro in jmorecfg.h is defined as the keyword that marks a function

+inline-able.  Some compilers have a switch that tells the compiler to inline

+any function it thinks is profitable (e.g., -finline-functions for gcc).

+Enabling such a switch is likely to make the compiled code bigger but faster.

+

+In general, it's worth trying the maximum optimization level of your compiler,

+and experimenting with any optional optimizations such as loop unrolling.

+(Unfortunately, far too many compilers have optimizer bugs ... be prepared to

+back off if the code fails self-test.)  If you do any experimentation along

+these lines, please report the optimal settings to jpeg-info@jpegclub.org so

+we can mention them in future releases.  Be sure to specify your machine and

+compiler version.

+

+

+HINTS FOR SPECIFIC SYSTEMS

+==========================

+

+We welcome reports on changes needed for systems not mentioned here.  Submit

+'em to jpeg-info@jpegclub.org.  Also, if configure or ckconfig.c is wrong

+about how to configure the JPEG software for your system, please let us know.

+

+

+Acorn RISC OS:

+

+(Thanks to Simon Middleton for these hints on compiling with Desktop C.)

+After renaming the files according to Acorn conventions, take a copy of

+makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and

+change these definitions as indicated:

+

+CFLAGS= -throwback -IC: -Wn

+LDLIBS=C:o.Stubs

+SYSDEPMEM=jmemansi.o

+LN=Link

+AR=LibFile -c -o

+

+Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'.  Remove the

+lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h'

+dependency section.

+

+Copy jconfig.txt to jconfig.h.  Edit jconfig.h to define TWO_FILE_COMMANDLINE

+and CHAR_IS_UNSIGNED.

+

+Run the makefile using !AMU not !Make.  If you want to use the 'clean' and

+'test' makefile entries then you will have to fiddle with the syntax a bit

+and rename the test files.

+

+

+Amiga:

+

+SAS C 6.50 reportedly is too buggy to compile the IJG code properly.

+A patch to update to 6.51 is available from SAS or AmiNet FTP sites.

+

+The supplied config files are set up to use jmemname.c as the memory

+manager, with temporary files being created on the device named by

+"JPEGTMP:".

+

+

+Atari ST/STE/TT:

+

+Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st

+to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively.  The

+project files should work as-is with Pure C.  For Turbo C, change library

+filenames "pc..." to "tc..." in each project file.  Note that libjpeg.prj

+selects jmemansi.c as the recommended memory manager.  You'll probably want to

+adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K

+less than your normal free memory.  Put "#define DEFAULT_MAX_MEM nnnn" into

+jconfig.h to do this.

+

+To use the 68881/68882 coprocessor for the floating point DCT, add the

+compiler option "-8" to the project files and replace pcfltlib.lib with

+pc881lib.lib in cjpeg.prj and djpeg.prj.  Or if you don't have a

+coprocessor, you may prefer to remove the float DCT code by undefining

+DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float

+code will be too slow to be useful).  In that case, you can delete

+pcfltlib.lib from the project files.

+

+Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp,

+or jpegtran.ttp.  You'll have to perform the self-test by hand.

+

+We haven't bothered to include project files for rdjpgcom and wrjpgcom.

+Those source files should just be compiled by themselves; they don't

+depend on the JPEG library.  You can use the default.prj project file

+of the Pure C distribution to make the programs.

+

+There is a bug in some older versions of the Turbo C library which causes the

+space used by temporary files created with "tmpfile()" not to be freed after

+an abnormal program exit.  If you check your disk afterwards, you will find

+cluster chains that are allocated but not used by a file.  This should not

+happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly

+close temp files before exiting.  But if you use the JPEG library with your

+own code, be sure to supply a signal catcher, or else use a different

+system-dependent memory manager.

+

+

+Cray:

+

+Should you be so fortunate as to be running JPEG on a Cray YMP, there is a

+compiler bug in old versions of Cray's Standard C (prior to 3.1).  If you

+still have an old compiler, you'll need to insert a line reading

+"#pragma novector" just before the loop 

+    for (i = 1; i <= (int) htbl->bits[l]; i++)

+      huffsize[p++] = (char) l;

+in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c).

+[This bug may or may not still occur with the current IJG code, but it's

+probably a dead issue anyway...]

+

+

+HP-UX:

+

+If you have HP-UX 7.05 or later with the "software development" C compiler,

+you should run the compiler in ANSI mode.  If using the configure script,

+say

+        ./configure CC='cc -Aa'

+(or -Ae if you prefer).  If configuring by hand, use makefile.ansi and add

+"-Aa" to the CFLAGS line in the makefile.

+

+If you have a pre-7.05 system, or if you are using the non-ANSI C compiler

+delivered with a minimum HP-UX system, then you must use makefile.unix

+(and do NOT add -Aa); or just run configure without the CC option.

+

+On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior

+to A.08.07.  If you get complaints about "not a typedef name", you'll have to

+use makefile.unix, or run configure without the CC option.

+

+

+Macintosh, generic comments:

+

+The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to

+provide a Unix-style command line interface.  You can use this interface on

+the Mac by means of the ccommand() library routine provided by Metrowerks

+CodeWarrior or Think C.  This is only appropriate for testing the library,

+however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want

+to develop a Mac-style user interface.  There isn't a complete example

+available at the moment, but there are some helpful starting points:

+1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to

+JPEG under System 7 and later.  This only illustrates how to use the

+compression half of the library, but it does a very nice job of that part.

+The CodeWarrior source code is available from http://www.pobox.com/~jsam.

+2. Jim Brunner prepared a Mac-style user interface for both compression and

+decompression.  Unfortunately, it hasn't been updated since IJG v4, and

+the library's API has changed considerably since then.  Still it may be of

+some help, particularly as a guide to compiling the IJG code under Think C.

+Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu

+or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx.

+

+jmemmac.c is the recommended memory manager back end for Macintosh.  It uses

+NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific

+implementation of jpeg_mem_available().  It also creates temporary files that

+follow Mac conventions.  (That part of the code relies on System-7-or-later OS

+functions.  See the comments in jmemmac.c if you need to run it on System 6.)

+NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c.

+

+You can also use jmemnobs.c, if you don't care about handling images larger

+than available memory.  If you use any memory manager back end other than

+jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and

+"DisposePtr", because Mac C libraries often have peculiar implementations of

+malloc/free.  (For instance, free() may not return the freed space to the

+Mac Memory Manager.  This is undesirable for the IJG code because jmemmgr.c

+already clumps space requests.)

+

+

+Macintosh, Metrowerks CodeWarrior:

+

+The Unix-command-line-style interface can be used by defining USE_CCOMMAND.

+You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout.

+This means that when using the cjpeg/djpeg programs, you'll have to type the

+input and output file names in the "Arguments" text-edit box, rather than

+using the file radio buttons.  (Perhaps USE_FDOPEN or USE_SETMODE would

+eliminate the problem, but I haven't heard from anyone who's tried it.)

+

+On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended

+float.  jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power

+of 2.  Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.

+

+The supplied configuration file jconfig.mac can be used for your jconfig.h;

+it includes all the recommended symbol definitions.  If you have AppleScript

+installed, you can run the supplied script makeproj.mac to create CodeWarrior

+project files for the library and the testbed applications, then build the

+library and applications.  (Thanks to Dan Sears and Don Agro for this nifty

+hack, which saves us from trying to maintain CodeWarrior project files as part

+of the IJG distribution...)

+

+

+Macintosh, Think C:

+

+The documentation in Jim Brunner's "JPEG Convert" source code (see above)

+includes detailed build instructions for Think C; it's probably somewhat

+out of date for the current release, but may be helpful.

+

+If you want to build the minimal command line version, proceed as follows.

+You'll have to prepare project files for the programs; we don't include any

+in the distribution since they are not text files.  Use the file lists in

+any of the supplied makefiles as a guide.  Also add the ANSI and Unix C

+libraries in a separate segment.  You may need to divide the JPEG files into

+more than one segment; we recommend dividing compression and decompression

+modules.  Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is

+called.  You must also define TWO_FILE_COMMANDLINE because stdin/stdout

+don't handle binary data correctly.

+

+On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float.

+jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2.

+Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint.

+

+jconfig.mac should work as a jconfig.h configuration file for Think C,

+but the makeproj.mac AppleScript script is specific to CodeWarrior.  Sorry.

+

+

+MIPS R3000:

+

+MIPS's cc version 1.31 has a rather nasty optimization bug.  Don't use -O

+if you have that compiler version.  (Use "cc -V" to check the version.)

+Note that the R3000 chip is found in workstations from DEC and others.

+

+

+MS-DOS, generic comments for 16-bit compilers:

+

+The IJG code is designed to work well in 80x86 "small" or "medium" memory

+models (i.e., data pointers are 16 bits unless explicitly declared "far";

+code pointers can be either size).  You may be able to use small model to

+compile cjpeg or djpeg by itself, but you will probably have to use medium

+model for any larger application.  This won't make much difference in

+performance.  You *will* take a noticeable performance hit if you use a

+large-data memory model, and you should avoid "huge" model if at all

+possible.  Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use

+a small-data memory model; be sure it is NOT defined if you use a large-data

+model.  (The supplied makefiles and jconfig files for Borland and Microsoft C

+compile in medium model and define NEED_FAR_POINTERS.)

+

+The DOS-specific memory manager, jmemdos.c, should be used if possible.

+It needs some assembly-code routines which are in jmemdosa.asm; make sure

+your makefile assembles that file and includes it in the library.  If you

+don't have a suitable assembler, you can get pre-assembled object files for

+jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip.  (DOS-oriented

+distributions of the IJG source code often include these object files.)

+

+When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set

+MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value).  If your

+C library's far-heap malloc() can't allocate blocks that large, reduce

+MAX_ALLOC_CHUNK to whatever it can handle.

+

+If you can't use jmemdos.c for some reason --- for example, because you

+don't have an assembler to assemble jmemdosa.asm --- you'll have to fall

+back to jmemansi.c or jmemname.c.  You'll probably still need to set

+MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc()

+more than 64K at a time.  IMPORTANT: if you use jmemansi.c or jmemname.c,

+you will have to compile in a large-data memory model in order to get the

+right stdio library.  Too bad.

+

+wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB

+work area to hold the comment text.  If your C library's malloc can't

+handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c.

+

+Most MS-DOS compilers treat stdin/stdout as text files, so you must use

+two-file command line style.  But if your compiler has either fdopen() or

+setmode(), you can use one-file style if you like.  To do this, define

+USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode.

+(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.)  You

+should test that I/O through stdin/stdout produces the same results as I/O

+to explicitly named files... the "make test" procedures in the supplied

+makefiles do NOT use stdin/stdout.

+

+

+MS-DOS, generic comments for 32-bit compilers:

+

+None of the above comments about memory models apply if you are using a

+32-bit flat-memory-space environment, such as DJGPP or Watcom C.  (And you

+should use one if you have it, as performance will be much better than

+8086-compatible code!)  For flat-memory-space compilers, do NOT define

+NEED_FAR_POINTERS, and do NOT use jmemdos.c.  Use jmemnobs.c if the

+environment supplies adequate virtual memory, otherwise use jmemansi.c or

+jmemname.c.

+

+You'll still need to be careful about binary I/O through stdin/stdout.

+See the last paragraph of the previous section.

+

+

+MS-DOS, Borland C:

+

+Be sure to convert all the source files to DOS text format (CR/LF newlines).

+Although Borland C will often work OK with unmodified Unix (LF newlines)

+source files, sometimes it will give bogus compile errors.

+"Illegal character '#'" is the most common such error.  (This is true with

+Borland C 3.1, but perhaps is fixed in newer releases.)

+

+If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.

+jconfig.bcc already includes #define USE_SETMODE to make this work.

+(fdopen does not work correctly.)

+

+

+MS-DOS, Microsoft C:

+

+makefile.mc6 works with Microsoft C, DOS Visual C++, etc.  It should only

+be used if you want to build a 16-bit (small or medium memory model) program.

+

+If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE.

+jconfig.mc6 already includes #define USE_SETMODE to make this work.

+(fdopen does not work correctly.)

+

+Note that this makefile assumes that the working copy of itself is called

+"makefile".  If you want to call it something else, say "makefile.mak",

+be sure to adjust the dependency line that reads "$(RFILE) : makefile".

+Otherwise the make will fail because it doesn't know how to create "makefile".

+Worse, some releases of Microsoft's make utilities give an incorrect error

+message in this situation.

+

+Old versions of MS C fail with an "out of macro expansion space" error

+because they can't cope with the macro TRACEMS8 (defined in jerror.h).

+If this happens to you, the easiest solution is to change TRACEMS8 to

+expand to nothing.  You'll lose the ability to dump out JPEG coefficient

+tables with djpeg -debug -debug, but at least you can compile.

+

+Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn

+off optimization entirely (remove -O from CFLAGS).  6.00A is better, but it

+still generates bad code if you enable loop optimizations (-Ol or -Ox).

+

+MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ...

+which is on by default.  To work around this bug, compile that one file

+with /Oo-.

+

+

+Microsoft Windows (all versions), generic comments:

+

+Some Windows system include files define typedef boolean as "unsigned char".

+The IJG code also defines typedef boolean, but we make it "int" by default.

+This doesn't affect the IJG programs because we don't import those Windows

+include files.  But if you use the JPEG library in your own program, and some

+of your program's files import one definition of boolean while some import the

+other, you can get all sorts of mysterious problems.  A good preventive step

+is to make the IJG library use "unsigned char" for boolean.  To do that,

+add something like this to your jconfig.h file:

+        /* Define "boolean" as unsigned char, not int, per Windows custom */

+        #ifndef __RPCNDR_H__    /* don't conflict if rpcndr.h already read */

+        typedef unsigned char boolean;

+        #endif

+        #define HAVE_BOOLEAN    /* prevent jmorecfg.h from redefining it */

+(This is already in jconfig.vc, by the way.)

+

+windef.h contains the declarations

+        #define far

+        #define FAR far

+Since jmorecfg.h tries to define FAR as empty, you may get a compiler

+warning if you include both jpeglib.h and windef.h (which windows.h

+includes).  To suppress the warning, you can put "#ifndef FAR"/"#endif"

+around the line "#define FAR" in jmorecfg.h.

+(Something like this is already in jmorecfg.h, by the way.)

+

+When using the library in a Windows application, you will almost certainly

+want to modify or replace the error handler module jerror.c, since our

+default error handler does a couple of inappropriate things:

+  1. it tries to write error and warning messages on stderr;

+  2. in event of a fatal error, it exits by calling exit().

+

+A simple stopgap solution for problem 1 is to replace the line

+        fprintf(stderr, "%s\n", buffer);

+(in output_message in jerror.c) with

+        MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR);

+It's highly recommended that you at least do that much, since otherwise

+error messages will disappear into nowhere.  (Beginning with IJG v6b, this

+code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in

+jconfig.h to enable it.)

+

+The proper solution for problem 2 is to return control to your calling

+application after a library error.  This can be done with the setjmp/longjmp

+technique discussed in libjpeg.txt and illustrated in example.c.  (NOTE:

+some older Windows C compilers provide versions of setjmp/longjmp that

+don't actually work under Windows.  You may need to use the Windows system

+functions Catch and Throw instead.)

+

+The recommended memory manager under Windows is jmemnobs.c; in other words,

+let Windows do any virtual memory management needed.  You should NOT use

+jmemdos.c nor jmemdosa.asm under Windows.

+

+For Windows 3.1, we recommend compiling in medium or large memory model;

+for newer Windows versions, use a 32-bit flat memory model.  (See the MS-DOS

+sections above for more info about memory models.)  In the 16-bit memory

+models only, you'll need to put

+        #define MAX_ALLOC_CHUNK 65520L  /* Maximum request to malloc() */

+into jconfig.h to limit allocation chunks to 64Kb.  (Without that, you'd

+have to use huge memory model, which slows things down unnecessarily.)

+jmemnobs.c works without modification in large or flat memory models, but to

+use medium model, you need to modify its jpeg_get_large and jpeg_free_large

+routines to allocate far memory.  In any case, you might like to replace

+its calls to malloc and free with direct calls on Windows memory allocation

+functions.

+

+You may also want to modify jdatasrc.c and jdatadst.c to use Windows file

+operations rather than fread/fwrite.  This is only necessary if your C

+compiler doesn't provide a competent implementation of C stdio functions.

+

+You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library

+will accept or deliver color pixels in BGR sample order, not RGB; BGR order

+is usually more convenient under Windows.  Note that this change will break

+the sample applications cjpeg/djpeg, but the library itself works fine.

+

+

+Many people want to convert the IJG library into a DLL.  This is reasonably

+straightforward, but watch out for the following:

+

+  1. Don't try to compile as a DLL in small or medium memory model; use

+large model, or even better, 32-bit flat model.  Many places in the IJG code

+assume the address of a local variable is an ordinary (not FAR) pointer;

+that isn't true in a medium-model DLL.

+

+  2. Microsoft C cannot pass file pointers between applications and DLLs.

+(See Microsoft Knowledge Base, PSS ID Number Q50336.)  So jdatasrc.c and

+jdatadst.c don't work if you open a file in your application and then pass

+the pointer to the DLL.  One workaround is to make jdatasrc.c/jdatadst.c

+part of your main application rather than part of the DLL.

+

+  3. You'll probably need to modify the macros GLOBAL() and EXTERN() to

+attach suitable linkage keywords to the exported routine names.  Similarly,

+you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers

+are declared in a way that lets application routines be called back through

+the function pointers.  These macros are in jmorecfg.h.  Typical definitions

+for a 16-bit DLL are:

+        #define GLOBAL(type)            type _far _pascal _loadds _export

+        #define EXTERN(type)            extern type _far _pascal _loadds

+        #define METHODDEF(type)         static type _far _pascal

+        #define JMETHOD(type,methodname,arglist)  \

+                type (_far _pascal *methodname) arglist

+For a 32-bit DLL you may want something like

+        #define GLOBAL(type)            __declspec(dllexport) type

+        #define EXTERN(type)            extern __declspec(dllexport) type

+Although not all the GLOBAL routines are actually intended to be called by

+the application, the performance cost of making them all DLL entry points is

+negligible.

+

+The unmodified IJG library presents a very C-specific application interface,

+so the resulting DLL is only usable from C or C++ applications.  There has

+been some talk of writing wrapper code that would present a simpler interface

+usable from other languages, such as Visual Basic.  This is on our to-do list

+but hasn't been very high priority --- any volunteers out there?

+

+

+Microsoft Windows, Borland C:

+

+The provided jconfig.bcc should work OK in a 32-bit Windows environment,

+but you'll need to tweak it in a 16-bit environment (you'd need to define

+NEED_FAR_POINTERS and MAX_ALLOC_CHUNK).  Beware that makefile.bcc will need

+alteration if you want to use it for Windows --- in particular, you should

+use jmemnobs.c not jmemdos.c under Windows.

+

+Borland C++ 4.5 fails with an internal compiler error when trying to compile

+jdmerge.c in 32-bit mode.  If enough people complain, perhaps Borland will fix

+it.  In the meantime, the simplest known workaround is to add a redundant

+definition of the variable range_limit in h2v1_merged_upsample(), at the head

+of the block that handles odd image width (about line 268 in v6 jdmerge.c):

+  /* If image width is odd, do the last output column separately */

+  if (cinfo->output_width & 1) {

+    register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */

+    cb = GETJSAMPLE(*inptr1);

+Pretty bizarre, especially since the very similar routine h2v2_merged_upsample

+doesn't trigger the bug.

+Recent reports suggest that this bug does not occur with "bcc32a" (the

+Pentium-optimized version of the compiler).

+

+Another report from a user of Borland C 4.5 was that incorrect code (leading

+to a color shift in processed images) was produced if any of the following

+optimization switch combinations were used: 

+        -Ot -Og

+        -Ot -Op

+        -Ot -Om

+So try backing off on optimization if you see such a problem.  (Are there

+several different releases all numbered "4.5"??)

+

+

+Microsoft Windows, Microsoft Visual C++:

+

+jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory

+model.  makefile.vc is intended for command-line use.  (If you are using

+the Developer Studio environment, you may prefer the DevStudio project

+files; see below.)

+

+IJG JPEG 7 adds extern "C" to jpeglib.h.  This avoids the need to put

+extern "C" { ... } around #include "jpeglib.h" in your C++ application.

+You can also force VC++ to treat the library as C++ code by renaming

+all the *.c files to *.cpp (and adjusting the makefile to match).

+In this case you also need to define the symbol DONT_USE_EXTERN_C in

+the configuration to prevent jpeglib.h from using extern "C".

+

+

+Microsoft Windows, Microsoft Visual C++ 6 Developer Studio:

+

+We include makefiles that should work as project files in DevStudio 6.0 or

+later.  There is a library makefile that builds the IJG library as a static

+Win32 library, and application makefiles that build the sample applications

+as Win32 console applications.  (Even if you only want the library, we

+recommend building the applications so that you can run the self-test.)

+

+To use:

+1. Open the command prompt, change to the main directory and execute the

+   command line

+        NMAKE /f makefile.vc  setup-vc6

+   This will move jconfig.vc to jconfig.h and makefiles to project files.

+   (Note that the renaming is critical!)

+2. Open the workspace file jpeg.dsw, build the library project.

+   (If you are using DevStudio more recent than 6.0, you'll probably

+   get a message saying that the project files are being updated.)

+3. Open the workspace file apps.dsw, build the application projects.

+4. To perform the self-test, execute the command line

+        NMAKE /f makefile.vc  test-build

+5. Move the application .exe files from `app`\Release to an

+   appropriate location on your path.

+

+

+Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10):

+

+We include makefiles that should work as project files in Visual Studio

+2010 or later.  There is a library makefile that builds the IJG library

+as a static Win32 library, and application makefiles that build the sample

+applications as Win32 console applications.  (Even if you only want the

+library, we recommend building the applications so that you can run the

+self-test.)

+

+To use:

+1. Open the command prompt, change to the main directory and execute the

+   command line

+        NMAKE /f makefile.vc  setup-v10

+   This will move jconfig.vc to jconfig.h and makefiles to project files.

+   (Note that the renaming is critical!)

+2. Open the solution file jpeg.sln, build the library project.

+   (If you are using Visual Studio more recent than 2010 (v10), you'll

+   probably get a message saying that the project files are being updated.)

+3. Open the solution file apps.sln, build the application projects.

+4. To perform the self-test, execute the command line

+        NMAKE /f makefile.vc  test-build

+5. Move the application .exe files from `app`\Release to an

+   appropriate location on your path.

+

+Note:

+There seems to be an optimization bug in the compiler which causes the

+self-test to fail with the color quantization option.

+We have disabled optimization for the file jquant2.c in the library

+project file which causes the self-test to pass properly.

+

+

+OS/2, Borland C++:

+

+Watch out for optimization bugs in older Borland compilers; you may need

+to back off the optimization switch settings.  See the comments in

+makefile.bcc.

+

+

+SGI:

+

+On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile.

+If you are using configure, you can do this by saying

+        ./configure RANLIB='ar -ts'

+This change is not needed on all SGIs.  Use it only if the make fails at the

+stage of linking the completed programs.

+

+On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2"

+reportedly speeds up the float DCT method substantially, enough to make it

+faster than the default int method (but still slower than the fast int

+method).  If you use -mips2, you may want to alter the default DCT method to

+be float.  To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h.

+

+

+VMS:

+

+On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1"

+qualifier with MMS when building the JPEG package.

+

+VAX/VMS v5.5-1 may have problems with the test step of the build procedure

+reporting differences when it compares the original and test images.  If the

+error points to the last block of the files, it is most likely bogus and may

+be safely ignored.  It seems to be because the files are Stream_LF and

+Backup/Compare has difficulty with the (presumably) null padded files.

+This problem was not observed on VAX/VMS v6.1 or AXP/VMS v6.1.

+

+/*

+ * YCbCr is defined per CCIR 601-1, except that Cb and Cr are

+ * normalized to the range 0..MAXJSAMPLE rather than -0.5 .. 0.5.

+ * The conversion equations to be implemented are therefore

+ *      Y  =  0.29900 * R + 0.58700 * G + 0.11400 * B

+ *      Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B  + CENTERJSAMPLE

+ *      Cr =  0.50000 * R - 0.41869 * G - 0.08131 * B  + CENTERJSAMPLE

+ * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)

+ * Note: older versions of the IJG code used a zero offset of MAXJSAMPLE/2,

+ * rather than CENTERJSAMPLE, for Cb and Cr.  This gave equal positive and

+ * negative swings for Cb/Cr, but meant that grayscale values (Cb=Cr=0)

+ * were not represented exactly.  Now we sacrifice exact representation of

+ * maximum red and maximum blue in order to get exact grayscales.

+ *

+ * To avoid floating-point arithmetic, we represent the fractional constants

+ * as integers scaled up by 2^16 (about 4 digits precision); we have to divide

+ * the products by 2^16, with appropriate rounding, to get the correct answer.

+ *

+ * For even more speed, we avoid doing any multiplications in the inner loop

+ * by precalculating the constants times R,G,B for all possible values.

+ * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);

+ * for 12-bit samples it is still acceptable.  It's not very reasonable for

+ * 16-bit samples, but if you want lossless storage you shouldn't be changing

+ * colorspace anyway.

+ * The CENTERJSAMPLE offsets and the rounding fudge-factor of 0.5 are included

+ * in the tables to save adding them separately in the inner loop.

+ * jcsample.c

+ *

+ * Copyright (C) 1991-1996, Thomas G. Lane.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains downsampling routines.

+ *

+ * Downsampling input data is counted in "row groups".  A row group

+ * is defined to be max_v_samp_factor pixel rows of each component,

+ * from which the downsampler produces v_samp_factor sample rows.

+ * A single row group is processed in each call to the downsampler module.

+ *

+ * The downsampler is responsible for edge-expansion of its output data

+ * to fill an integral number of DCT blocks horizontally.  The source buffer

+ * may be modified if it is helpful for this purpose (the source buffer is

+ * allocated wide enough to correspond to the desired output width).

+ * The caller (the prep controller) is responsible for vertical padding.

+ *

+ * The downsampler may request "context rows" by setting need_context_rows

+ * during startup.  In this case, the input arrays will contain at least

+ * one row group's worth of pixels above and below the passed-in data;

+ * the caller will create dummy rows at image top and bottom by replicating

+ * the first or last real pixel row.

+ *

+ * An excellent reference for image resampling is

+ *   Digital Image Warping, George Wolberg, 1990.

+ *   Pub. by IEEE Computer Society Press, Los Alamitos, CA. ISBN 0-8186-8944-7.

+ *

+ * The downsampling algorithm used here is a simple average of the source

+ * pixels covered by the output pixel.  The hi-falutin sampling literature

+ * refers to this as a "box filter".  In general the characteristics of a box

+ * filter are not very good, but for the specific cases we normally use (1:1

+ * and 2:1 ratios) the box is equivalent to a "triangle filter" which is not

+ * nearly so bad.  If you intend to use other sampling ratios, you'd be well

+ * advised to improve this code.

+ *

+ * A simple input-smoothing capability is provided.  This is mainly intended

+ * for cleaning up color-dithered GIF input files (if you find it inadequate,

+ * we suggest using an external filtering program such as pnmconvol).  When

+ * enabled, each input pixel P is replaced by a weighted sum of itself and its

+ * eight neighbors.  P's weight is 1-8*SF and each neighbor's weight is SF,

+ * where SF = (smoothing_factor / 1024).

+ * Currently, smoothing is only supported for 2h2v sampling factors.

+ * YCbCr is defined per CCIR 601-1, except that Cb and Cr are

+ * The conversion equations to be implemented are therefore

+ *

+ *      R = Y                + 1.40200 * Cr

+ *      G = Y - 0.34414 * Cb - 0.71414 * Cr

+ *      Y = 0.29900 * R + 0.58700 * G + 0.11400 * B

+ *

+ * where Cb and Cr represent the incoming values less CENTERJSAMPLE.

+ * (These numbers are derived from TIFF 6.0 section 21, dated 3-June-92.)

+ *

+ * To avoid floating-point arithmetic, we represent the fractional constants

+ * as integers scaled up by 2^16 (about 4 digits precision); we have to divide

+ * the products by 2^16, with appropriate rounding, to get the correct answer.

+ * Notice that Y, being an integral input, does not contribute any fraction

+ * so it need not participate in the rounding.

+ *

+ * For even more speed, we avoid doing any multiplications in the inner loop

+ * by precalculating the constants times Cb and Cr for all possible values.

+ * For 8-bit JSAMPLEs this is very reasonable (only 256 entries per table);

+ * for 12-bit samples it is still acceptable.  It's not very reasonable for

+ * 16-bit samples, but if you want lossless storage you shouldn't be changing

+ * colorspace anyway.

+ * The Cr=>R and Cb=>B values can be rounded to integers in advance; the

+ * values for the G calculation are left scaled up, since we must add them

+/*

+ * In the current system design, the main buffer need never be a full-image

+ * buffer; any full-height buffers will be found inside the coefficient or

+ * postprocessing controllers.  Nonetheless, the main controller is not

+ * trivial.  Its responsibility is to provide context rows for upsampling/

+ * rescaling, and doing this in an efficient fashion is a bit tricky.

+ *

+ * Postprocessor input data is counted in "row groups".  A row group

+ * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size)

+ * sample rows of each component.  (We require DCT_scaled_size values to be

+ * chosen such that these numbers are integers.  In practice DCT_scaled_size

+ * values will likely be powers of two, so we actually have the stronger

+ * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.)

+ * Upsampling will typically produce max_v_samp_factor pixel rows from each

+ * row group (times any additional scale factor that the upsampler is

+ * applying).

+ *

+ * The coefficient controller will deliver data to us one iMCU row at a time;

+ * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or

+ * exactly min_DCT_scaled_size row groups.  (This amount of data corresponds

+ * to one row of MCUs when the image is fully interleaved.)  Note that the

+ * number of sample rows varies across components, but the number of row

+ * groups does not.  Some garbage sample rows may be included in the last iMCU

+ * row at the bottom of the image.

+ *

+ * Depending on the vertical scaling algorithm used, the upsampler may need

+ * access to the sample row(s) above and below its current input row group.

+ * The upsampler is required to set need_context_rows TRUE at global selection

+ * time if so.  When need_context_rows is FALSE, this controller can simply

+ * obtain one iMCU row at a time from the coefficient controller and dole it

+ * out as row groups to the postprocessor.

+ *

+ * When need_context_rows is TRUE, this controller guarantees that the buffer

+ * passed to postprocessing contains at least one row group's worth of samples

+ * above and below the row group(s) being processed.  Note that the context

+ * rows "above" the first passed row group appear at negative row offsets in

+ * the passed buffer.  At the top and bottom of the image, the required

+ * context rows are manufactured by duplicating the first or last real sample

+ * row; this avoids having special cases in the upsampling inner loops.

+ *

+ * The amount of context is fixed at one row group just because that's a

+ * convenient number for this controller to work with.  The existing

+ * upsamplers really only need one sample row of context.  An upsampler

+ * supporting arbitrary output rescaling might wish for more than one row

+ * group of context when shrinking the image; tough, we don't handle that.

+ * (This is justified by the assumption that downsizing will be handled mostly

+ * by adjusting the DCT_scaled_size values, so that the actual scale factor at

+ * the upsample step needn't be much less than one.)

+ *

+ * To provide the desired context, we have to retain the last two row groups

+ * of one iMCU row while reading in the next iMCU row.  (The last row group

+ * can't be processed until we have another row group for its below-context,

+ * and so we have to save the next-to-last group too for its above-context.)

+ * We could do this most simply by copying data around in our buffer, but

+ * that'd be very slow.  We can avoid copying any data by creating a rather

+ * strange pointer structure.  Here's how it works.  We allocate a workspace

+ * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number

+ * of row groups per iMCU row).  We create two sets of redundant pointers to

+ * the workspace.  Labeling the physical row groups 0 to M+1, the synthesized

+ * pointer lists look like this:

+ *                   M+1                          M-1

+ * master pointer --> 0         master pointer --> 0

+ *                    1                            1

+ *                   ...                          ...

+ *                   M-3                          M-3

+ *                   M-2                           M

+ *                   M-1                          M+1

+ *                    M                           M-2

+ *                   M+1                          M-1

+ *                    0                            0

+ * We read alternate iMCU rows using each master pointer; thus the last two

+ * row groups of the previous iMCU row remain un-overwritten in the workspace.

+ * The pointer lists are set up so that the required context rows appear to

+ * be adjacent to the proper places when we pass the pointer lists to the

+ * upsampler.

+ *

+ * The above pictures describe the normal state of the pointer lists.

+ * At top and bottom of the image, we diddle the pointer lists to duplicate

+ * the first or last sample row as necessary (this is cheaper than copying

+ * sample rows around).

+ *

+ * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1.  In that

+ * situation each iMCU row provides only one row group so the buffering logic

+ * must be different (eg, we must read two iMCU rows before we can emit the

+ * first row group).  For now, we simply do not support providing context

+ * rows when min_DCT_scaled_size is 1.  That combination seems unlikely to

+ * be worth providing --- if someone wants a 1/8th-size preview, they probably

+ * want it quick and dirty, so a context-free upsampler is sufficient.

+ * Exit: if return TRUE, have read and processed any parameters, and have

+ *   updated the restart point to point after the parameters.

+ *   marker parameters; restart point has not been moved.  Same routine

+ *   will be called again after application supplies more input data.

+ *

+ * This approach to suspension assumes that all of a marker's parameters

+ * can fit into a single input bufferload.  This should hold for "normal"

+ * markers.  Some COM/APPn markers might have large parameter segments

+ * that might not fit.  If we are simply dropping such a marker, we use

+ * skip_input_data to get past it, and thereby put the problem on the

+ * source manager's shoulders.  If we are saving the marker's contents

+ * into memory, we use a slightly different convention: when forced to

+ * suspend, the marker processor updates the restart point to the end of

+ * what its consumed (ie, the end of the buffer) before returning FALSE.

+ * On resumption, cinfo->unread_marker still contains the marker code,

+ * but the data source will point to the next chunk of marker data.

+ * The marker processor must retain internal state to deal with this.

+ *

+ * Note that we don't bother to avoid duplicate trace messages if a

+ * suspension occurs within marker parameters.  Other side effects

+ * require more care.

+ *

+ * read_restart_marker calls resync_to_restart if it finds a marker other than

+ * the restart marker it was expecting.  (This code is *not* used unless

+ * a nonzero restart interval has been declared.)  cinfo->unread_marker is

+ * the marker code actually found (might be anything, except 0 or FF).

+ * The desired restart marker number (0..7) is passed as a parameter.

+ * This routine is supposed to apply whatever error recovery strategy seems

+ * appropriate in order to position the input stream to the next data segment.

+ * Note that cinfo->unread_marker is treated as a marker appearing before

+ * the current data-source input point; usually it should be reset to zero

+ * before returning.

+ * Returns FALSE if suspension is required.

+ *

+ * This implementation is substantially constrained by wanting to treat the

+ * input as a data stream; this means we can't back up.  Therefore, we have

+ * only the following actions to work with:

+ *   1. Simply discard the marker and let the entropy decoder resume at next

+ *      byte of file.

+ *   2. Read forward until we find another marker, discarding intervening

+ *      data.  (In theory we could look ahead within the current bufferload,

+ *      without having to discard data if we don't find the desired marker.

+ *      This idea is not implemented here, in part because it makes behavior

+ *      dependent on buffer size and chance buffer-boundary positions.)

+ *   3. Leave the marker unread (by failing to zero cinfo->unread_marker).

+ *      This will cause the entropy decoder to process an empty data segment,

+ *      inserting dummy zeroes, and then we will reprocess the marker.

+ *

+ * #2 is appropriate if we think the desired marker lies ahead, while #3 is

+ * appropriate if the found marker is a future restart marker (indicating

+ * that we have missed the desired restart marker, probably because it got

+ * corrupted).

+ * We apply #2 or #3 if the found marker is a restart marker no more than

+ * two counts behind or ahead of the expected one.  We also apply #2 if the

+ * found marker is not a legal JPEG marker code (it's certainly bogus data).

+ * If the found marker is a restart marker more than 2 counts away, we do #1

+ * (too much risk that the marker is erroneous; with luck we will be able to

+ * resync at some future point).

+ * For any valid non-restart JPEG marker, we apply #3.  This keeps us from

+ * overrunning the end of a scan.  An implementation limited to single-scan

+ * files might find it better to apply #2 for markers other than EOI, since

+ * any other marker would have to be bogus data in that case.

+ * Several decompression processes need to range-limit values to the range

+ * 0..MAXJSAMPLE; the input value may fall somewhat outside this range

+ * due to noise introduced by quantization, roundoff error, etc.  These

+ * processes are inner loops and need to be as fast as possible.  On most

+ * machines, particularly CPUs with pipelines or instruction prefetch,

+ * a (subscript-check-less) C table lookup

+ *              x = sample_range_limit[x];

+ * is faster than explicit tests

+ *              if (x < 0)  x = 0;

+ *              else if (x > MAXJSAMPLE)  x = MAXJSAMPLE;

+ * These processes all use a common table prepared by the routine below.

+ *

+ * For most steps we can mathematically guarantee that the initial value

+ * of x is within MAXJSAMPLE+1 of the legal range, so a table running from

+ * -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient.  But for the initial

+ * limiting step (just after the IDCT), a wildly out-of-range value is 

+ * possible if the input data is corrupt.  To avoid any chance of indexing

+ * off the end of memory and getting a bad-pointer trap, we perform the

+ * post-IDCT limiting thus:

+ *              x = range_limit[x & MASK];

+ * where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit

+ * samples.  Under normal circumstances this is more than enough range and

+ * a correct output will be generated; with bogus input data the mask will

+ * cause wraparound, and we will safely generate a bogus-but-in-range output.

+ * For the post-IDCT step, we want to convert the data from signed to unsigned

+ * representation by adding CENTERJSAMPLE at the same time that we limit it.

+ * So the post-IDCT limiting table ends up looking like this:

+ *   CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,

+ *   MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),

+ *   0          (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),

+ *   0,1,...,CENTERJSAMPLE-1

+ * Negative inputs select values from the upper half of the table after

+ * masking.

+ *

+ * We can save some space by overlapping the start of the post-IDCT table

+ * with the simpler range limiting table.  The post-IDCT table begins at

+ * sample_range_limit + CENTERJSAMPLE.

+ *

+ * Note that the table is allocated in near data space on PCs; it's small

+ * enough and used often enough to justify this.

+ *

+ * Copyright (C) 1994-1996, Thomas G. Lane.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains code for merged upsampling/color conversion.

+ *

+ * This file combines functions from jdsample.c and jdcolor.c;

+ * read those files first to understand what's going on.

+ *

+ * When the chroma components are to be upsampled by simple replication

+ * (ie, box filtering), we can save some work in color conversion by

+ * calculating all the output pixels corresponding to a pair of chroma

+ * samples at one time.  In the conversion equations

+ *      R = Y           + K1 * Cr

+ *      G = Y + K2 * Cb + K3 * Cr

+ *      B = Y + K4 * Cb

+ * only the Y term varies among the group of pixels corresponding to a pair

+ * of chroma samples, so the rest of the terms can be calculated just once.

+ * At typical sampling ratios, this eliminates half or three-quarters of the

+ * multiplications needed for color conversion.

+ *

+ * This file currently provides implementations for the following cases:

+ *      YCbCr => RGB color conversion only.

+ *      Sampling ratios of 2h1v or 2h2v.

+ *      No scaling needed at upsample time.

+ *      Corner-aligned (non-CCIR601) sampling alignment.

+ * Other special cases could be added, but in most applications these are

+ * the only common cases.  (For uncommon cases we fall back on the more

+ * general code in jdsample.c and jdcolor.c.)

+This archive contains already-assembled object files for JMEMDOSA.ASM

+of the Independent JPEG Group's JPEG package.  These files will be helpful

+if you want to compile the IJG code for DOS, but don't have an assembler.

+

+These files were prepared from the 3/13/1992 version of JMEMDOSA.ASM,

+which is still unchanged as of mid-1998.  You can use these files with

+releases 3 through 6 of the IJG code, and probably future releases too.

+

+To use these files, copy the proper version to JMEMDOSA.OBJ.  Make sure

+this file has a newer date than JMEMDOSA.ASM.  Then compile the code as

+usual.

+

+Object files included:

+

+JDOSAMSC.OBJ    For Microsoft C version 5 or later.

+JDOSABCC.OBJ    For Borland C version 3.0 or later.

+ * This file contains a floating-point implementation of the

+ *

+ * This implementation should be more accurate than either of the integer

+ * DCT implementations.  However, it may not give the same results on all

+ * machines because of differences in roundoff behavior.  Speed will depend

+ * on the hardware's floating point capacity.

+ *

+ * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT

+ * on each column.  Direct algorithms are also available, but they are

+ * much more complex and seem not to be any faster when reduced to code.

+ *

+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for

+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in

+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell

+ * JPEG textbook (see REFERENCES section in file README).  The following code

+ * is based directly on figure 4-8 in P&M.

+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is

+ * possible to arrange the computation so that many of the multiplies are

+ * simple scalings of the final outputs.  These multiplies can then be

+ * folded into the multiplications or divisions by the JPEG quantization

+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds

+ * to be done in the DCT itself.

+ * The primary disadvantage of this method is that with a fixed-point

+ * implementation, accuracy is lost due to imprecise representation of the

+ * scaled quantization values.  However, that problem does not arise if

+ * we use floating point arithmetic.

+ * jfdctint.c

+ *

+ * Copyright (C) 1991-1996, Thomas G. Lane.

+ * Modification developed 2003-2009 by Guido Vollbeding.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains a slow-but-accurate integer implementation of the

+ * forward DCT (Discrete Cosine Transform).

+ *

+ * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT

+ * on each column.  Direct algorithms are also available, but they are

+ * much more complex and seem not to be any faster when reduced to code.

+ *

+ * This implementation is based on an algorithm described in

+ *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT

+ *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,

+ *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.

+ * The primary algorithm described there uses 11 multiplies and 29 adds.

+ * We use their alternate method with 12 multiplies and 32 adds.

+ * The advantage of this method is that no data path contains more than one

+ * multiplication; this allows a very simple and accurate implementation in

+ * scaled fixed-point arithmetic, with a minimal number of shifts.

+ *

+ * We also provide FDCT routines with various input sample block sizes for

+ * direct resolution reduction or enlargement and for direct resolving the

+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN

+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 output DCT block.

+ *

+ * For N<8 we fill the remaining block coefficients with zero.

+ * For N>8 we apply a partial N-point FDCT on the input samples, computing

+ * just the lower 8 frequency coefficients and discarding the rest.

+ *

+ * We must scale the output coefficients of the N-point FDCT appropriately

+ * to the standard 8-point FDCT level by 8/N per 1-D pass.  This scaling

+ * is folded into the constant multipliers (pass 2) and/or final/initial

+ * shifting.

+ *

+ * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases

+ * since there would be too many additional constants to pre-calculate.

+ * The poop on this scaling stuff is as follows:

+ *

+ * Each 1-D DCT step produces outputs which are a factor of sqrt(N)

+ * larger than the true DCT outputs.  The final outputs are therefore

+ * a factor of N larger than desired; since N=8 this can be cured by

+ * a simple right shift at the end of the algorithm.  The advantage of

+ * this arrangement is that we save two multiplications per 1-D DCT,

+ * because the y0 and y4 outputs need not be divided by sqrt(N).

+ * In the IJG code, this factor of 8 is removed by the quantization step

+ * (in jcdctmgr.c), NOT in this module.

+ *

+ * We have to do addition and subtraction of the integer inputs, which

+ * is no problem, and multiplication by fractional constants, which is

+ * a problem to do in integer arithmetic.  We multiply all the constants

+ * by CONST_SCALE and convert them to integer constants (thus retaining

+ * CONST_BITS bits of precision in the constants).  After doing a

+ * multiplication we have to divide the product by CONST_SCALE, with proper

+ * rounding, to produce the correct output.  This division can be done

+ * cheaply as a right shift of CONST_BITS bits.  We postpone shifting

+ * as long as possible so that partial sums can be added together with

+ * full fractional precision.

+ *

+ * The outputs of the first pass are scaled up by PASS1_BITS bits so that

+ * they are represented to better-than-integral precision.  These outputs

+ * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word

+ * with the recommended scaling.  (For 12-bit sample data, the intermediate

+ * array is INT32 anyway.)

+ *

+ * To avoid overflow of the 32-bit intermediate results in pass 2, we must

+ * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis

+ * shows that the values given below are the most effective.

+ * jidctflt.c

+ *

+ * Copyright (C) 1994-1998, Thomas G. Lane.

+ * Modified 2010 by Guido Vollbeding.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains a floating-point implementation of the

+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine

+ * must also perform dequantization of the input coefficients.

+ *

+ * This implementation should be more accurate than either of the integer

+ * IDCT implementations.  However, it may not give the same results on all

+ * machines because of differences in roundoff behavior.  Speed will depend

+ * on the hardware's floating point capacity.

+ *

+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT

+ * on each row (or vice versa, but it's more convenient to emit a row at

+ * a time).  Direct algorithms are also available, but they are much more

+ * complex and seem not to be any faster when reduced to code.

+ *

+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for

+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in

+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell

+ * JPEG textbook (see REFERENCES section in file README).  The following code

+ * is based directly on figure 4-8 in P&M.

+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is

+ * possible to arrange the computation so that many of the multiplies are

+ * simple scalings of the final outputs.  These multiplies can then be

+ * folded into the multiplications or divisions by the JPEG quantization

+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds

+ * to be done in the DCT itself.

+ * The primary disadvantage of this method is that with a fixed-point

+ * implementation, accuracy is lost due to imprecise representation of the

+ * scaled quantization values.  However, that problem does not arise if

+ * we use floating point arithmetic.

+ *

+ * Copyright (C) 1994-1998, Thomas G. Lane.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains a fast, not so accurate integer implementation of the

+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine

+ * must also perform dequantization of the input coefficients.

+ *

+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT

+ * on each row (or vice versa, but it's more convenient to emit a row at

+ * a time).  Direct algorithms are also available, but they are much more

+ * complex and seem not to be any faster when reduced to code.

+ *

+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for

+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in

+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell

+ * JPEG textbook (see REFERENCES section in file README).  The following code

+ * is based directly on figure 4-8 in P&M.

+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is

+ * possible to arrange the computation so that many of the multiplies are

+ * simple scalings of the final outputs.  These multiplies can then be

+ * folded into the multiplications or divisions by the JPEG quantization

+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds

+ * to be done in the DCT itself.

+ * The primary disadvantage of this method is that with fixed-point math,

+ * accuracy is lost due to imprecise representation of the scaled

+ * quantization values.  The smaller the quantization table entry, the less

+ * precise the scaled value, so this implementation does worse with high-

+ * quality-setting files than with low-quality ones.

+ * (right shift) multiplication products as soon as they are formed,

+ * rather than carrying additional fractional bits into subsequent additions.

+ * This compromises accuracy slightly, but it lets us save a few shifts.

+ * More importantly, 16-bit arithmetic is then adequate (for 8-bit samples)

+ * everywhere except in the multiplications proper; this saves a good deal

+ * of work on 16-bit-int machines.

+ *

+ * The dequantized coefficients are not integers because the AA&N scaling

+ * factors have been incorporated.  We represent them scaled up by PASS1_BITS,

+ * so that the first and second IDCT rounds have the same input scaling.

+ * For 8-bit JSAMPLEs, we choose IFAST_SCALE_BITS = PASS1_BITS so as to

+ * avoid a descaling shift; this compromises accuracy rather drastically

+ * for small quantization table entries, but it saves a lot of shifts.

+ * For 12-bit JSAMPLEs, there's no hope of using 16x16 multiplies anyway,

+ * so we use a much larger scaling factor to preserve accuracy.

+ *

+ * A final compromise is to represent the multiplicative constants to only

+ * 8 fractional bits, rather than 13.  This saves some shifting work on some

+ * machines, and may also reduce the cost of multiplication (since there

+ * jidctint.c

+ *

+ * Copyright (C) 1991-1998, Thomas G. Lane.

+ * Modification developed 2002-2009 by Guido Vollbeding.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains a slow-but-accurate integer implementation of the

+ * inverse DCT (Discrete Cosine Transform).  In the IJG code, this routine

+ * must also perform dequantization of the input coefficients.

+ *

+ * A 2-D IDCT can be done by 1-D IDCT on each column followed by 1-D IDCT

+ * on each row (or vice versa, but it's more convenient to emit a row at

+ * a time).  Direct algorithms are also available, but they are much more

+ * complex and seem not to be any faster when reduced to code.

+ *

+ * This implementation is based on an algorithm described in

+ *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT

+ *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,

+ *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.

+ * The primary algorithm described there uses 11 multiplies and 29 adds.

+ * We use their alternate method with 12 multiplies and 32 adds.

+ * The advantage of this method is that no data path contains more than one

+ * multiplication; this allows a very simple and accurate implementation in

+ * scaled fixed-point arithmetic, with a minimal number of shifts.

+ *

+ * We also provide IDCT routines with various output sample block sizes for

+ * direct resolution reduction or enlargement and for direct resolving the

+ * common 2x1 and 1x2 subsampling cases without additional resampling: NxN

+ * (N=1...16), 2NxN, and Nx2N (N=1...8) pixels for one 8x8 input DCT block.

+ *

+ * For N<8 we simply take the corresponding low-frequency coefficients of

+ * the 8x8 input DCT block and apply an NxN point IDCT on the sub-block

+ * to yield the downscaled outputs.

+ * This can be seen as direct low-pass downsampling from the DCT domain

+ * point of view rather than the usual spatial domain point of view,

+ * yielding significant computational savings and results at least

+ * as good as common bilinear (averaging) spatial downsampling.

+ *

+ * For N>8 we apply a partial NxN IDCT on the 8 input coefficients as

+ * lower frequencies and higher frequencies assumed to be zero.

+ * It turns out that the computational effort is similar to the 8x8 IDCT

+ * regarding the output size.

+ * Furthermore, the scaling and descaling is the same for all IDCT sizes.

+ *

+ * CAUTION: We rely on the FIX() macro except for the N=1,2,4,8 cases

+ * since there would be too many additional constants to pre-calculate.

+ * The poop on this scaling stuff is as follows:

+ *

+ * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)

+ * larger than the true IDCT outputs.  The final outputs are therefore

+ * a factor of N larger than desired; since N=8 this can be cured by

+ * a simple right shift at the end of the algorithm.  The advantage of

+ * this arrangement is that we save two multiplications per 1-D IDCT,

+ * because the y0 and y4 inputs need not be divided by sqrt(N).

+ *

+ * We have to do addition and subtraction of the integer inputs, which

+ * is no problem, and multiplication by fractional constants, which is

+ * a problem to do in integer arithmetic.  We multiply all the constants

+ * by CONST_SCALE and convert them to integer constants (thus retaining

+ * CONST_BITS bits of precision in the constants).  After doing a

+ * multiplication we have to divide the product by CONST_SCALE, with proper

+ * rounding, to produce the correct output.  This division can be done

+ * cheaply as a right shift of CONST_BITS bits.  We postpone shifting

+ * as long as possible so that partial sums can be added together with

+ * full fractional precision.

+ *

+ * The outputs of the first pass are scaled up by PASS1_BITS bits so that

+ * they are represented to better-than-integral precision.  These outputs

+ * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word

+ * with the recommended scaling.  (To scale up 12-bit sample data further, an

+ * intermediate INT32 array would be needed.)

+ *

+ * To avoid overflow of the 32-bit intermediate results in pass 2, we must

+ * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis

+ * shows that the values given below are the most effective.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file provides an MS-DOS-compatible implementation of the system-

+ * dependent portion of the JPEG memory manager.  Temporary data can be

+ * stored in extended or expanded memory as well as in regular DOS files.

+ *

+ * If you use this file, you must be sure that NEED_FAR_POINTERS is defined

+ * if you compile in a small-data memory model; it should NOT be defined if

+ * you use a large-data memory model.  This file is not recommended if you

+ * are using a flat-memory-space 386 environment such as DJGCC or Watcom C.

+ * Also, this code will NOT work if struct fields are aligned on greater than

+ * 2-byte boundaries.

+ *

+ * Based on code contributed by Ge' Weijers.

+ */

+

+/*

+ * If you have both extended and expanded memory, you may want to change the

+ * order in which they are tried in jopen_backing_store.  On a 286 machine

+ * expanded memory is usually faster, since extended memory access involves

+ * an expensive protected-mode-and-back switch.  On 386 and better, extended

+ * memory is usually faster.  As distributed, the code tries extended memory

+ * first (what? not everyone has a 386? :-).

+ *

+ * You can disable use of extended/expanded memory entirely by altering these

+ * definitions or overriding them from the Makefile (eg, -DEMS_SUPPORTED=0).

+; This file is part of the Independent JPEG Group's software.

+; For conditions of distribution and use, see the accompanying README file.

+;

+; This file contains low-level interface routines to support the MS-DOS

+; backing store manager (jmemdos.c).  Routines are provided to access disk

+; files through direct DOS calls, and to access XMS and EMS drivers.

+;

+; This file should assemble with Microsoft's MASM or any compatible

+; assembler (including Borland's Turbo Assembler).  If you haven't got

+; a compatible assembler, better fall back to jmemansi.c or jmemname.c.

+;

+; To minimize dependence on the C compiler's register usage conventions,

+; we save and restore all 8086 registers, even though most compilers only

+; require SI,DI,DS to be preserved.  Also, we use only 16-bit-wide return

+; values, which everybody returns in AX.

+;

+; Based on code contributed by Ge' Weijers.

+ *

+ * Copyright (C) 1992-1997, Thomas G. Lane.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * jmemmac.c provides an Apple Macintosh implementation of the system-

+ * dependent portion of the JPEG memory manager.

+ *

+ * If you use jmemmac.c, then you must define USE_MAC_MEMMGR in the

+ * JPEG_INTERNALS part of jconfig.h.

+ *

+ * jmemmac.c uses the Macintosh toolbox routines NewPtr and DisposePtr

+ * instead of malloc and free.  It accurately determines the amount of

+ * memory available by using CompactMem.  Notice that if left to its

+ * own devices, this code can chew up all available space in the

+ * application's zone, with the exception of the rather small "slop"

+ * factor computed in jpeg_mem_available().  The application can ensure

+ * that more space is left over by reducing max_memory_to_use.

+ *

+ * Large images are swapped to disk using temporary files and System 7.0+'s

+ * temporary folder functionality.

+ *

+ * Note that jmemmac.c depends on two features of MacOS that were first

+ * introduced in System 7: FindFolder and the FSSpec-based calls.

+ * If your application uses jmemmac.c and is run under System 6 or earlier,

+ * and the jpeg library decides it needs a temporary file, it will abort,

+ * printing error messages about requiring System 7.  (If no temporary files

+ * are created, it will run fine.)

+ *

+ * If you want to use jmemmac.c in an application that might be used with

+ * System 6 or earlier, then you should remove dependencies on FindFolder

+ * and the FSSpec calls.  You will need to replace FindFolder with some

+ * other mechanism for finding a place to put temporary files, and you

+ * should replace the FSSpec calls with their HFS equivalents:

+ *

+ *     FSpDelete     ->  HDelete

+ *     FSpGetFInfo   ->  HGetFInfo

+ *     FSpCreate     ->  HCreate

+ *     FSpOpenDF     ->  HOpen      *** Note: not HOpenDF ***

+ *     FSMakeFSSpec  ->  (fill in spec by hand.)

+ *

+ * (Use HOpen instead of HOpenDF.  HOpen is just a glue-interface to PBHOpen,

+ * which is on all HFS macs.  HOpenDF is a System 7 addition which avoids the

+ * ages-old problem of names starting with a period.)

+ *

+ * Contributed by Sam Bushell (jsam@iagu.on.net) and

+ * Dan Gildor (gyld@in-touch.com).

+ * About virtual array management:

+ *

+ * The above "normal" array routines are only used to allocate strip buffers

+ * (as wide as the image, but just a few rows high).  Full-image-sized buffers

+ * are handled as "virtual" arrays.  The array is still accessed a strip at a

+ * time, but the memory manager must save the whole array for repeated

+ * accesses.  The intended implementation is that there is a strip buffer in

+ * memory (as high as is possible given the desired memory limit), plus a

+ * backing file that holds the rest of the array.

+ *

+ * The request_virt_array routines are told the total size of the image and

+ * the maximum number of rows that will be accessed at once.  The in-memory

+ * buffer must be at least as large as the maxaccess value.

+ *

+ * The request routines create control blocks but not the in-memory buffers.

+ * That is postponed until realize_virt_arrays is called.  At that time the

+ * total amount of space needed is known (approximately, anyway), so free

+ * memory can be divided up fairly.

+ *

+ * The access_virt_array routines are responsible for making a specific strip

+ * area accessible (after reading or writing the backing file, if necessary).

+ * Note that the access routines are told whether the caller intends to modify

+ * the accessed strip; during a read-only pass this saves having to rewrite

+ * data to disk.  The access routines are also responsible for pre-zeroing

+ * any newly accessed rows, if pre-zeroing was requested.

+ *

+ * In current usage, the access requests are usually for nonoverlapping

+ * strips; that is, successive access start_row numbers differ by exactly

+ * num_rows = maxaccess.  This means we can get good performance with simple

+ * buffer dump/reload logic, by making the in-memory buffer be a multiple

+ * of the access height; then there will never be accesses across bufferload

+ * boundaries.  The code will still work with overlapping access requests,

+ * but it doesn't handle bufferload overlaps very efficiently.

+ * Selection of a file name for a temporary file.

+ *

+ * The code as given is suitable for most Unix systems, and it is easily

+ * modified for most non-Unix systems.  Some notes:

+ *  1.  The temp file is created in the directory named by TEMP_DIRECTORY.

+ *      The default value is /usr/tmp, which is the conventional place for

+ *      creating large temp files on Unix.  On other systems you'll probably

+ *      want to change the file location.  You can do this by editing the

+ *      #define, or (preferred) by defining TEMP_DIRECTORY in jconfig.h.

+ *

+ *  2.  If you need to change the file name as well as its location,

+ *      you can override the TEMP_FILE_NAME macro.  (Note that this is

+ *      actually a printf format string; it must contain %s and %d.)

+ *      Few people should need to do this.

+ *

+ *  3.  mktemp() is used to ensure that multiple processes running

+ *      simultaneously won't select the same file names.  If your system

+ *      doesn't have mktemp(), define NO_MKTEMP to do it the hard way.

+ *      (If you don't have <errno.h>, also define NO_ERRNO_H.)

+ *

+ *  4.  You probably want to define NEED_SIGNAL_CATCHER so that cjpeg.c/djpeg.c

+ *      will cause the temp files to be removed if you stop the program early.

+.SH NAME

+jpegtran \- lossless transformation of JPEG files

+.SH SYNOPSIS

+.B jpegtran

+[

+.I options

+]

+[

+.I filename

+]

+.LP

+.SH DESCRIPTION

+.LP

+.B jpegtran

+performs various useful transformations of JPEG files.

+It can translate the coded representation from one variant of JPEG to another,

+for example from baseline JPEG to progressive JPEG or vice versa.  It can also

+perform some rearrangements of the image data, for example turning an image

+from landscape to portrait format by rotation.

+.PP

+.B jpegtran

+works by rearranging the compressed data (DCT coefficients), without

+ever fully decoding the image.  Therefore, its transformations are lossless:

+there is no image degradation at all, which would not be true if you used

+.B djpeg

+followed by

+.B cjpeg

+to accomplish the same conversion.  But by the same token,

+.B jpegtran

+cannot perform lossy operations such as changing the image quality.

+.PP

+.B jpegtran

+reads the named JPEG/JFIF file, or the standard input if no file is

+named, and produces a JPEG/JFIF file on the standard output.

+.SH OPTIONS

+All switch names may be abbreviated; for example,

+.B \-optimize

+may be written

+.B \-opt

+or

+.BR \-o .

+Upper and lower case are equivalent.

+British spellings are also accepted (e.g.,

+.BR \-optimise ),

+though for brevity these are not mentioned below.

+.PP

+To specify the coded JPEG representation used in the output file,

+.B jpegtran

+accepts a subset of the switches recognized by

+.BR cjpeg :

+.TP

+.B \-optimize

+Perform optimization of entropy encoding parameters.

+.TP

+.B \-progressive

+Create progressive JPEG file.

+.TP

+.BI \-restart " N"

+Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is

+attached to the number.

+.TP

+.B \-arithmetic

+Use arithmetic coding.

+.TP

+.BI \-scans " file"

+Use the scan script given in the specified text file.

+.PP

+See

+.BR cjpeg (1)

+for more details about these switches.

+If you specify none of these switches, you get a plain baseline-JPEG output

+file.  The quality setting and so forth are determined by the input file.

+.PP

+The image can be losslessly transformed by giving one of these switches:

+.TP

+.B \-flip horizontal

+Mirror image horizontally (left-right).

+.TP

+.B \-flip vertical

+Mirror image vertically (top-bottom).

+.TP

+.B \-rotate 90

+Rotate image 90 degrees clockwise.

+.TP

+.B \-rotate 180

+Rotate image 180 degrees.

+.TP

+.B \-rotate 270

+Rotate image 270 degrees clockwise (or 90 ccw).

+.TP

+.B \-transpose

+Transpose image (across UL-to-LR axis).

+.TP

+.B \-transverse

+Transverse transpose (across UR-to-LL axis).

+.IP

+The transpose transformation has no restrictions regarding image dimensions.

+The other transformations operate rather oddly if the image dimensions are not

+a multiple of the iMCU size (usually 8 or 16 pixels), because they can only

+transform complete blocks of DCT coefficient data in the desired way.

+.IP

+.BR jpegtran 's

+default behavior when transforming an odd-size image is designed

+to preserve exact reversibility and mathematical consistency of the

+transformation set.  As stated, transpose is able to flip the entire image

+area.  Horizontal mirroring leaves any partial iMCU column at the right edge

+untouched, but is able to flip all rows of the image.  Similarly, vertical

+mirroring leaves any partial iMCU row at the bottom edge untouched, but is

+able to flip all columns.  The other transforms can be built up as sequences

+of transpose and flip operations; for consistency, their actions on edge

+pixels are defined to be the same as the end result of the corresponding

+transpose-and-flip sequence.

+.IP

+For practical use, you may prefer to discard any untransformable edge pixels

+rather than having a strange-looking strip along the right and/or bottom edges

+of a transformed image.  To do this, add the

+.B \-trim

+switch:

+.TP

+.B \-trim

+Drop non-transformable edge blocks.

+.IP

+Obviously, a transformation with

+.B \-trim

+is not reversible, so strictly speaking

+.B jpegtran

+with this switch is not lossless.  Also, the expected mathematical

+equivalences between the transformations no longer hold.  For example,

+.B \-rot 270 -trim

+trims only the bottom edge, but

+.B \-rot 90 -trim

+followed by

+.B \-rot 180 -trim

+trims both edges.

+.IP

+If you are only interested in perfect transformation, add the

+.B \-perfect

+switch:

+.TP

+.B \-perfect

+Fails with an error if the transformation is not perfect.

+.IP

+For example you may want to do

+.IP

+.B (jpegtran \-rot 90 -perfect

+.I foo.jpg

+.B || djpeg

+.I foo.jpg

+.B | pnmflip \-r90 | cjpeg)

+.IP

+to do a perfect rotation if available or an approximated one if not.

+.PP

+We also offer a lossless-crop option, which discards data outside a given

+image region but losslessly preserves what is inside.  Like the rotate and

+flip transforms, lossless crop is restricted by the current JPEG format: the

+upper left corner of the selected region must fall on an iMCU boundary.  If

+this does not hold for the given crop parameters, we silently move the upper

+left corner up and/or left to make it so, simultaneously increasing the region

+dimensions to keep the lower right crop corner unchanged.  (Thus, the output

+image covers at least the requested region, but may cover more.)

+

+The image can be losslessly cropped by giving the switch:

+.TP

+.B \-crop WxH+X+Y

+Crop to a rectangular subarea of width W, height H starting at point X,Y.

+.PP

+Other not-strictly-lossless transformation switches are:

+.TP

+.B \-grayscale

+Force grayscale output.

+.IP

+This option discards the chrominance channels if the input image is YCbCr

+(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The

+luminance channel is preserved exactly, so this is a better method of reducing

+to grayscale than decompression, conversion, and recompression.  This switch

+is particularly handy for fixing a monochrome picture that was mistakenly

+encoded as a color JPEG.  (In such a case, the space savings from getting rid

+of the near-empty chroma channels won't be large; but the decoding time for

+a grayscale JPEG is substantially less than that for a color JPEG.)

+.TP

+.BI \-scale " M/N"

+Scale the output image by a factor M/N.

+.IP

+Currently supported scale factors are M/N with all M from 1 to 16, where N is

+the source DCT size, which is 8 for baseline JPEG.  If the /N part is omitted,

+then M specifies the DCT scaled size to be applied on the given input.  For

+baseline JPEG this is equivalent to M/8 scaling, since the source DCT size

+for baseline JPEG is 8.

+.B Caution:

+An implementation of the JPEG SmartScale extension is required for this

+feature.  SmartScale enabled JPEG is not yet widely implemented, so many

+decoders will be unable to view a SmartScale extended JPEG file at all.

+.PP

+.B jpegtran

+also recognizes these switches that control what to do with "extra" markers,

+such as comment blocks:

+.TP

+.B \-copy none

+Copy no extra markers from source file.  This setting suppresses all

+comments and other excess baggage present in the source file.

+.TP

+.B \-copy comments

+Copy only comment markers.  This setting copies comments from the source file,

+but discards any other inessential (for image display) data.

+.TP

+.B \-copy all

+Copy all extra markers.  This setting preserves miscellaneous markers

+found in the source file, such as JFIF thumbnails, Exif data, and Photoshop

+settings.  In some files these extra markers can be sizable.

+.IP

+The default behavior is

+.BR "\-copy comments" .

+(Note: in IJG releases v6 and v6a,

+.B jpegtran

+always did the equivalent of

+.BR "\-copy none" .)

+.PP

+Additional switches recognized by jpegtran are:

+.TP

+.BI \-maxmemory " N"

+Set limit for amount of memory to use in processing large images.  Value is

+in thousands of bytes, or millions of bytes if "M" is attached to the

+number.  For example,

+.B \-max 4m

+selects 4000000 bytes.  If more space is needed, temporary files will be used.

+.TP

+.BI \-outfile " name"

+Send output image to the named file, not to standard output.

+.TP

+.B \-verbose

+Enable debug printout.  More

+.BR \-v 's

+give more output.  Also, version information is printed at startup.

+.TP

+.B \-debug

+Same as

+.BR \-verbose .

+.SH EXAMPLES

+.LP

+This example converts a baseline JPEG file to progressive form:

+.IP

+.B jpegtran \-progressive

+.I foo.jpg

+.B >

+.I fooprog.jpg

+.PP

+This example rotates an image 90 degrees clockwise, discarding any

+unrotatable edge pixels:

+.IP

+.B jpegtran \-rot 90 -trim

+.I foo.jpg

+.B >

+.I foo90.jpg

+.SH ENVIRONMENT

+.TP

+.B JPEGMEM

+If this environment variable is set, its value is the default memory limit.

+The value is specified as described for the

+.B \-maxmemory

+switch.

+.B JPEGMEM

+overrides the default value specified when the program was compiled, and

+itself is overridden by an explicit

+.BR \-maxmemory .

+.SH AUTHOR

+Independent JPEG Group

+.SH BUGS

+The transform options can't transform odd-size images perfectly.  Use

+.B \-trim

+or

+.B \-perfect

+if you don't like the results.

+.PP

+The entire image is read into memory and then written out again, even in

+cases where this isn't really necessary.  Expect swapping on large images,

+especially when using the more complex transform options.

+/*

+ * The main purpose of 1-pass quantization is to provide a fast, if not very

+ * high quality, colormapped output capability.  A 2-pass quantizer usually

+ * gives better visual quality; however, for quantized grayscale output this

+ * quantizer is perfectly adequate.  Dithering is highly recommended with this

+ * quantizer, though you can turn it off if you really want to.

+ *

+ * In 1-pass quantization the colormap must be chosen in advance of seeing the

+ * image.  We use a map consisting of all combinations of Ncolors[i] color

+ * values for the i'th component.  The Ncolors[] values are chosen so that

+ * their product, the total number of colors, is no more than that requested.

+ * (In most cases, the product will be somewhat less.)

+ *

+ * Since the colormap is orthogonal, the representative value for each color

+ * component can be determined without considering the other components;

+ * then these indexes can be combined into a colormap index by a standard

+ * N-dimensional-array-subscript calculation.  Most of the arithmetic involved

+ * can be precalculated and stored in the lookup table colorindex[].

+ * colorindex[i][j] maps pixel value j in component i to the nearest

+ * representative value (grid plane) for that component; this index is

+ * multiplied by the array stride for component i, so that the

+ * index of the colormap entry closest to a given pixel value is just

+ *    sum( colorindex[component-number][pixel-component-value] )

+ * Aside from being fast, this scheme allows for variable spacing between

+ * representative values with no additional lookup cost.

+ *

+ * If gamma correction has been applied in color conversion, it might be wise

+ * to adjust the color grid spacing so that the representative colors are

+ * equidistant in linear space.  At this writing, gamma correction is not

+ * implemented by jdcolor, so nothing is done here.

+ */

+

+

+/* Declarations for ordered dithering.

+ *

+ * We use a standard 16x16 ordered dither array.  The basic concept of ordered

+ * dithering is described in many references, for instance Dale Schumacher's

+ * chapter II.2 of Graphics Gems II (James Arvo, ed. Academic Press, 1991).

+ * In place of Schumacher's comparisons against a "threshold" value, we add a

+ * "dither" value to the input pixel and then round the result to the nearest

+ * output value.  The dither value is equivalent to (0.5 - threshold) times

+ * the distance between output values.  For ordered dithering, we assume that

+ * the output colors are equally spaced; if not, results will probably be

+ * worse, since the dither may be too much or too little at a given point.

+ *

+ * The normal calculation would be to form pixel value + dither, range-limit

+ * this to 0..MAXJSAMPLE, and then index into the colorindex table as usual.

+ * We can skip the separate range-limiting step by extending the colorindex

+ * table in both directions.

+ *

+ * Errors are accumulated into the array fserrors[], at a resolution of

+ * 1/16th of a pixel count.  The error at a given pixel is propagated

+ * to its not-yet-processed neighbors using the standard F-S fractions,

+ *              ...     (here)  7/16

+ *              3/16    5/16    1/16

+ * We work left-to-right on even rows, right-to-left on odd rows.

+ *

+ * We can get away with a single array (holding one row's worth of errors)

+ * by using it to store the current row's errors at pixel columns not yet

+ * processed, but the next row's errors at columns already processed.  We

+ * need only a few extra variables to hold the errors immediately around the

+ * current column.  (If we are lucky, those variables are in registers, but

+ * even if not, they're probably cheaper to access than array elements are.)

+ *

+ * The fserrors[] array is indexed [component#][position].

+ * We provide (#columns + 2) entries per component; the extra entry at each

+ * end saves us from special-casing the first and last pixels.

+ *

+ * Note: on a wide image, we might not have enough room in a PC's near data

+ * segment to hold the error array; so it is allocated with alloc_large.

+ * This module implements the well-known Heckbert paradigm for color

+ * quantization.  Most of the ideas used here can be traced back to

+ * Heckbert's seminal paper

+ *   Heckbert, Paul.  "Color Image Quantization for Frame Buffer Display",

+ *   Proc. SIGGRAPH '82, Computer Graphics v.16 #3 (July 1982), pp 297-304.

+ *

+ * In the first pass over the image, we accumulate a histogram showing the

+ * usage count of each possible color.  To keep the histogram to a reasonable

+ * size, we reduce the precision of the input; typical practice is to retain

+ * 5 or 6 bits per color, so that 8 or 4 different input values are counted

+ * in the same histogram cell.

+ *

+ * Next, the color-selection step begins with a box representing the whole

+ * color space, and repeatedly splits the "largest" remaining box until we

+ * have as many boxes as desired colors.  Then the mean color in each

+ * remaining box becomes one of the possible output colors.

+ * 

+ * The second pass over the image maps each input pixel to the closest output

+ * color (optionally after applying a Floyd-Steinberg dithering correction).

+ * This mapping is logically trivial, but making it go fast enough requires

+ * considerable care.

+ *

+ * Heckbert-style quantizers vary a good deal in their policies for choosing

+ * the "largest" box and deciding where to cut it.  The particular policies

+ * used here have proved out well in experimental comparisons, but better ones

+ * may yet be found.

+ *

+ * In earlier versions of the IJG code, this module quantized in YCbCr color

+ * space, processing the raw upsampled data without a color conversion step.

+ * This allowed the color conversion math to be done only once per colormap

+ * entry, not once per pixel.  However, that optimization precluded other

+ * useful optimizations (such as merging color conversion with upsampling)

+ * and it also interfered with desired capabilities such as quantizing to an

+ * externally-supplied colormap.  We have therefore abandoned that approach.

+ * The present code works in the post-conversion color space, typically RGB.

+ *

+ * To improve the visual quality of the results, we actually work in scaled

+ * RGB space, giving G distances more weight than R, and R in turn more than

+ * B.  To do everything in integer math, we must use integer scale factors.

+ * The 2/3/1 scale factors used here correspond loosely to the relative

+ * weights of the colors in the NTSC grayscale equation.

+ * If you want to use this code to quantize a non-RGB color space, you'll

+ * probably need to change these scale factors.

+ */

+ * and B,G,R orders.  If you define some other weird order in jmorecfg.h,

+ * you'll get compile errors until you extend this logic.  In that case

+ * First we have the histogram data structure and routines for creating it.

+ * The number of bits of precision can be adjusted by changing these symbols.

+ * We recommend keeping 6 bits for G and 5 each for R and B.

+ * If you have plenty of memory and cycles, 6 bits all around gives marginally

+ * better results; if you are short of memory, 5 bits all around will save

+ * some space but degrade the results.

+ * To maintain a fully accurate histogram, we'd need to allocate a "long"

+ * (preferably unsigned long) for each cell.  In practice this is overkill;

+ * we can get by with 16 bits per cell.  Few of the cell counts will overflow,

+ * and clamping those that do overflow to the maximum value will give close-

+ * enough results.  This reduces the recommended histogram size from 256Kb

+ * to 128Kb, which is a useful savings on PC-class machines.

+ * (In the second pass the histogram space is re-used for pixel mapping data;

+ * in that capacity, each cell must be able to store zero to the number of

+ * desired colors.  16 bits/cell is plenty for that too.)

+ * Since the JPEG code is intended to run in small memory model on 80x86

+ * machines, we can't just allocate the histogram in one chunk.  Instead

+ * of a true 3-D array, we use a row of pointers to 2-D arrays.  Each

+ * pointer corresponds to a C0 value (typically 2^5 = 32 pointers) and

+ * each 2-D array has 2^6*2^5 = 2048 or 2^6*2^6 = 4096 entries.  Note that

+ * These routines are concerned with the time-critical task of mapping input

+ * colors to the nearest color in the selected colormap.

+ *

+ * We re-use the histogram space as an "inverse color map", essentially a

+ * cache for the results of nearest-color searches.  All colors within a

+ * histogram cell will be mapped to the same colormap entry, namely the one

+ * closest to the cell's center.  This may not be quite the closest entry to

+ * the actual input color, but it's almost as good.  A zero in the cache

+ * indicates we haven't found the nearest color for that cell yet; the array

+ * is cleared to zeroes before starting the mapping pass.  When we find the

+ * nearest color for a cell, its colormap index plus one is recorded in the

+ * cache for future use.  The pass2 scanning routines call fill_inverse_cmap

+ * when they need to use an unfilled entry in the cache.

+ *

+ * Our method of efficiently finding nearest colors is based on the "locally

+ * sorted search" idea described by Heckbert and on the incremental distance

+ * calculation described by Spencer W. Thomas in chapter III.1 of Graphics

+ * Gems II (James Arvo, ed.  Academic Press, 1991).  Thomas points out that

+ * the distances from a given colormap entry to each cell of the histogram can

+ * be computed quickly using an incremental method: the differences between

+ * distances to adjacent cells themselves differ by a constant.  This allows a

+ * fairly fast implementation of the "brute force" approach of computing the

+ * distance from every colormap entry to every histogram cell.  Unfortunately,

+ * it needs a work array to hold the best-distance-so-far for each histogram

+ * cell (because the inner loop has to be over cells, not colormap entries).

+ * The work array elements have to be INT32s, so the work array would need

+ * 256Kb at our recommended precision.  This is not feasible in DOS machines.

+ *

+ * To get around these problems, we apply Thomas' method to compute the

+ * nearest colors for only the cells within a small subbox of the histogram.

+ * The work array need be only as big as the subbox, so the memory usage

+ * problem is solved.  Furthermore, we need not fill subboxes that are never

+ * referenced in pass2; many images use only part of the color gamut, so a

+ * fair amount of work is saved.  An additional advantage of this

+ * approach is that we can apply Heckbert's locality criterion to quickly

+ * eliminate colormap entries that are far away from the subbox; typically

+ * three-fourths of the colormap entries are rejected by Heckbert's criterion,

+ * and we need not compute their distances to individual cells in the subbox.

+ * The speed of this approach is heavily influenced by the subbox size: too

+ * small means too much overhead, too big loses because Heckbert's criterion

+ * can't eliminate as many colormap entries.  Empirically the best subbox

+ * size seems to be about 1/512th of the histogram (1/8th in each direction).

+ *

+ * Thomas' article also describes a refined method which is asymptotically

+ * faster than the brute-force method, but it is also far more complex and

+ * cannot efficiently be applied to small subboxes.  It is therefore not

+ * useful for programs intended to be portable to DOS machines.  On machines

+ * with plenty of memory, filling the whole histogram in one shot with Thomas'

+ * refined method might be faster than the present code --- but then again,

+ * it might not be any faster, and it's certainly more complicated.

+USING THE IJG JPEG LIBRARY

+

+Copyright (C) 1994-2011, Thomas G. Lane, Guido Vollbeding.

+This file is part of the Independent JPEG Group's software.

+For conditions of distribution and use, see the accompanying README file.

+

+

+This file describes how to use the IJG JPEG library within an application

+program.  Read it if you want to write a program that uses the library.

+

+The file example.c provides heavily commented skeleton code for calling the

+JPEG library.  Also see jpeglib.h (the include file to be used by application

+programs) for full details about data structures and function parameter lists.

+The library source code, of course, is the ultimate reference.

+

+Note that there have been *major* changes from the application interface

+presented by IJG version 4 and earlier versions.  The old design had several

+inherent limitations, and it had accumulated a lot of cruft as we added

+features while trying to minimize application-interface changes.  We have

+sacrificed backward compatibility in the version 5 rewrite, but we think the

+improvements justify this.

+

+OVERVIEW

+========

+

+Functions provided by the library

+---------------------------------

+

+The IJG JPEG library provides C code to read and write JPEG-compressed image

+files.  The surrounding application program receives or supplies image data a

+scanline at a time, using a straightforward uncompressed image format.  All

+details of color conversion and other preprocessing/postprocessing can be

+handled by the library.

+

+The library includes a substantial amount of code that is not covered by the

+JPEG standard but is necessary for typical applications of JPEG.  These

+functions preprocess the image before JPEG compression or postprocess it after

+decompression.  They include colorspace conversion, downsampling/upsampling,

+and color quantization.  The application indirectly selects use of this code

+by specifying the format in which it wishes to supply or receive image data.

+For example, if colormapped output is requested, then the decompression

+library automatically invokes color quantization.

+

+A wide range of quality vs. speed tradeoffs are possible in JPEG processing,

+and even more so in decompression postprocessing.  The decompression library

+provides multiple implementations that cover most of the useful tradeoffs,

+ranging from very-high-quality down to fast-preview operation.  On the

+compression side we have generally not provided low-quality choices, since

+compression is normally less time-critical.  It should be understood that the

+low-quality modes may not meet the JPEG standard's accuracy requirements;

+nonetheless, they are useful for viewers.

+

+A word about functions *not* provided by the library.  We handle a subset of

+the ISO JPEG standard; most baseline, extended-sequential, and progressive

+JPEG processes are supported.  (Our subset includes all features now in common

+use.)  Unsupported ISO options include:

+        * Hierarchical storage

+        * Lossless JPEG

+        * DNL marker

+        * Nonintegral subsampling ratios

+We support both 8- and 12-bit data precision, but this is a compile-time

+choice rather than a run-time choice; hence it is difficult to use both

+precisions in a single application.

+

+By itself, the library handles only interchange JPEG datastreams --- in

+particular the widely used JFIF file format.  The library can be used by

+surrounding code to process interchange or abbreviated JPEG datastreams that

+are embedded in more complex file formats.  (For example, this library is

+used by the free LIBTIFF library to support JPEG compression in TIFF.)

+

+

+Outline of typical usage

+------------------------

+

+The rough outline of a JPEG compression operation is:

+

+        Allocate and initialize a JPEG compression object

+        Specify the destination for the compressed data (eg, a file)

+        Set parameters for compression, including image size & colorspace

+        jpeg_start_compress(...);

+        while (scan lines remain to be written)

+                jpeg_write_scanlines(...);

+        jpeg_finish_compress(...);

+        Release the JPEG compression object

+

+A JPEG compression object holds parameters and working state for the JPEG

+library.  We make creation/destruction of the object separate from starting

+or finishing compression of an image; the same object can be re-used for a

+series of image compression operations.  This makes it easy to re-use the

+same parameter settings for a sequence of images.  Re-use of a JPEG object

+also has important implications for processing abbreviated JPEG datastreams,

+as discussed later.

+

+The image data to be compressed is supplied to jpeg_write_scanlines() from

+in-memory buffers.  If the application is doing file-to-file compression,

+reading image data from the source file is the application's responsibility.

+The library emits compressed data by calling a "data destination manager",

+which typically will write the data into a file; but the application can

+provide its own destination manager to do something else.

+

+Similarly, the rough outline of a JPEG decompression operation is:

+

+        Allocate and initialize a JPEG decompression object

+        Specify the source of the compressed data (eg, a file)

+        Call jpeg_read_header() to obtain image info

+        Set parameters for decompression

+        jpeg_start_decompress(...);

+        while (scan lines remain to be read)

+                jpeg_read_scanlines(...);

+        jpeg_finish_decompress(...);

+        Release the JPEG decompression object

+

+This is comparable to the compression outline except that reading the

+datastream header is a separate step.  This is helpful because information

+about the image's size, colorspace, etc is available when the application

+selects decompression parameters.  For example, the application can choose an

+output scaling ratio that will fit the image into the available screen size.

+

+The decompression library obtains compressed data by calling a data source

+manager, which typically will read the data from a file; but other behaviors

+can be obtained with a custom source manager.  Decompressed data is delivered

+into in-memory buffers passed to jpeg_read_scanlines().

+

+It is possible to abort an incomplete compression or decompression operation

+by calling jpeg_abort(); or, if you do not need to retain the JPEG object,

+simply release it by calling jpeg_destroy().

+

+JPEG compression and decompression objects are two separate struct types.

+However, they share some common fields, and certain routines such as

+jpeg_destroy() can work on either type of object.

+

+The JPEG library has no static variables: all state is in the compression

+or decompression object.  Therefore it is possible to process multiple

+compression and decompression operations concurrently, using multiple JPEG

+objects.

+

+Both compression and decompression can be done in an incremental memory-to-

+memory fashion, if suitable source/destination managers are used.  See the

+section on "I/O suspension" for more details.

+

+

+BASIC LIBRARY USAGE

+===================

+

+Data formats

+------------

+

+Before diving into procedural details, it is helpful to understand the

+image data format that the JPEG library expects or returns.

+

+The standard input image format is a rectangular array of pixels, with each

+pixel having the same number of "component" or "sample" values (color

+channels).  You must specify how many components there are and the colorspace

+interpretation of the components.  Most applications will use RGB data

+(three components per pixel) or grayscale data (one component per pixel).

+PLEASE NOTE THAT RGB DATA IS THREE SAMPLES PER PIXEL, GRAYSCALE ONLY ONE.

+A remarkable number of people manage to miss this, only to find that their

+programs don't work with grayscale JPEG files.

+

+There is no provision for colormapped input.  JPEG files are always full-color

+or full grayscale (or sometimes another colorspace such as CMYK).  You can

+feed in a colormapped image by expanding it to full-color format.  However

+JPEG often doesn't work very well with source data that has been colormapped,

+because of dithering noise.  This is discussed in more detail in the JPEG FAQ

+and the other references mentioned in the README file.

+

+Pixels are stored by scanlines, with each scanline running from left to

+right.  The component values for each pixel are adjacent in the row; for

+example, R,G,B,R,G,B,R,G,B,... for 24-bit RGB color.  Each scanline is an

+array of data type JSAMPLE --- which is typically "unsigned char", unless

+you've changed jmorecfg.h.  (You can also change the RGB pixel layout, say

+to B,G,R order, by modifying jmorecfg.h.  But see the restrictions listed in

+that file before doing so.)

+

+A 2-D array of pixels is formed by making a list of pointers to the starts of

+scanlines; so the scanlines need not be physically adjacent in memory.  Even

+if you process just one scanline at a time, you must make a one-element

+pointer array to conform to this structure.  Pointers to JSAMPLE rows are of

+type JSAMPROW, and the pointer to the pointer array is of type JSAMPARRAY.

+

+The library accepts or supplies one or more complete scanlines per call.

+It is not possible to process part of a row at a time.  Scanlines are always

+processed top-to-bottom.  You can process an entire image in one call if you

+have it all in memory, but usually it's simplest to process one scanline at

+a time.

+

+For best results, source data values should have the precision specified by

+BITS_IN_JSAMPLE (normally 8 bits).  For instance, if you choose to compress

+data that's only 6 bits/channel, you should left-justify each value in a

+byte before passing it to the compressor.  If you need to compress data

+that has more than 8 bits/channel, compile with BITS_IN_JSAMPLE = 12.

+(See "Library compile-time options", later.)

+

+

+The data format returned by the decompressor is the same in all details,

+except that colormapped output is supported.  (Again, a JPEG file is never

+colormapped.  But you can ask the decompressor to perform on-the-fly color

+quantization to deliver colormapped output.)  If you request colormapped

+output then the returned data array contains a single JSAMPLE per pixel;

+its value is an index into a color map.  The color map is represented as

+a 2-D JSAMPARRAY in which each row holds the values of one color component,

+that is, colormap[i][j] is the value of the i'th color component for pixel

+value (map index) j.  Note that since the colormap indexes are stored in

+JSAMPLEs, the maximum number of colors is limited by the size of JSAMPLE

+(ie, at most 256 colors for an 8-bit JPEG library).

+

+

+Compression details

+-------------------

+

+Here we revisit the JPEG compression outline given in the overview.

+

+1. Allocate and initialize a JPEG compression object.

+

+A JPEG compression object is a "struct jpeg_compress_struct".  (It also has

+a bunch of subsidiary structures which are allocated via malloc(), but the

+application doesn't control those directly.)  This struct can be just a local

+variable in the calling routine, if a single routine is going to execute the

+whole JPEG compression sequence.  Otherwise it can be static or allocated

+from malloc().

+

+You will also need a structure representing a JPEG error handler.  The part

+of this that the library cares about is a "struct jpeg_error_mgr".  If you

+are providing your own error handler, you'll typically want to embed the

+jpeg_error_mgr struct in a larger structure; this is discussed later under

+"Error handling".  For now we'll assume you are just using the default error

+handler.  The default error handler will print JPEG error/warning messages

+on stderr, and it will call exit() if a fatal error occurs.

+

+You must initialize the error handler structure, store a pointer to it into

+the JPEG object's "err" field, and then call jpeg_create_compress() to

+initialize the rest of the JPEG object.

+

+Typical code for this step, if you are using the default error handler, is

+

+        struct jpeg_compress_struct cinfo;

+        struct jpeg_error_mgr jerr;

+        ...

+        cinfo.err = jpeg_std_error(&jerr);

+        jpeg_create_compress(&cinfo);

+

+jpeg_create_compress allocates a small amount of memory, so it could fail

+if you are out of memory.  In that case it will exit via the error handler;

+that's why the error handler must be initialized first.

+

+

+2. Specify the destination for the compressed data (eg, a file).

+

+As previously mentioned, the JPEG library delivers compressed data to a

+"data destination" module.  The library includes one data destination

+module which knows how to write to a stdio stream.  You can use your own

+destination module if you want to do something else, as discussed later.

+

+If you use the standard destination module, you must open the target stdio

+stream beforehand.  Typical code for this step looks like:

+

+        FILE * outfile;

+        ...

+        if ((outfile = fopen(filename, "wb")) == NULL) {

+            fprintf(stderr, "can't open %s\n", filename);

+            exit(1);

+        }

+        jpeg_stdio_dest(&cinfo, outfile);

+

+where the last line invokes the standard destination module.

+

+WARNING: it is critical that the binary compressed data be delivered to the

+output file unchanged.  On non-Unix systems the stdio library may perform

+newline translation or otherwise corrupt binary data.  To suppress this

+behavior, you may need to use a "b" option to fopen (as shown above), or use

+setmode() or another routine to put the stdio stream in binary mode.  See

+cjpeg.c and djpeg.c for code that has been found to work on many systems.

+

+You can select the data destination after setting other parameters (step 3),

+if that's more convenient.  You may not change the destination between

+calling jpeg_start_compress() and jpeg_finish_compress().

+

+

+3. Set parameters for compression, including image size & colorspace.

+

+You must supply information about the source image by setting the following

+fields in the JPEG object (cinfo structure):

+

+        image_width             Width of image, in pixels

+        image_height            Height of image, in pixels

+        input_components        Number of color channels (samples per pixel)

+        in_color_space          Color space of source image

+

+The image dimensions are, hopefully, obvious.  JPEG supports image dimensions

+of 1 to 64K pixels in either direction.  The input color space is typically

+RGB or grayscale, and input_components is 3 or 1 accordingly.  (See "Special

+color spaces", later, for more info.)  The in_color_space field must be

+assigned one of the J_COLOR_SPACE enum constants, typically JCS_RGB or

+JCS_GRAYSCALE.

+

+JPEG has a large number of compression parameters that determine how the

+image is encoded.  Most applications don't need or want to know about all

+these parameters.  You can set all the parameters to reasonable defaults by

+calling jpeg_set_defaults(); then, if there are particular values you want

+to change, you can do so after that.  The "Compression parameter selection"

+section tells about all the parameters.

+

+You must set in_color_space correctly before calling jpeg_set_defaults(),

+because the defaults depend on the source image colorspace.  However the

+other three source image parameters need not be valid until you call

+jpeg_start_compress().  There's no harm in calling jpeg_set_defaults() more

+than once, if that happens to be convenient.

+

+Typical code for a 24-bit RGB source image is

+

+        cinfo.image_width = Width;      /* image width and height, in pixels */

+        cinfo.image_height = Height;

+        cinfo.input_components = 3;     /* # of color components per pixel */

+        cinfo.in_color_space = JCS_RGB; /* colorspace of input image */

+

+        jpeg_set_defaults(&cinfo);

+        /* Make optional parameter settings here */

+

+

+4. jpeg_start_compress(...);

+

+After you have established the data destination and set all the necessary

+source image info and other parameters, call jpeg_start_compress() to begin

+a compression cycle.  This will initialize internal state, allocate working

+storage, and emit the first few bytes of the JPEG datastream header.

+

+Typical code:

+

+        jpeg_start_compress(&cinfo, TRUE);

+

+The "TRUE" parameter ensures that a complete JPEG interchange datastream

+will be written.  This is appropriate in most cases.  If you think you might

+want to use an abbreviated datastream, read the section on abbreviated

+datastreams, below.

+

+Once you have called jpeg_start_compress(), you may not alter any JPEG

+parameters or other fields of the JPEG object until you have completed

+the compression cycle.

+

+

+5. while (scan lines remain to be written)

+        jpeg_write_scanlines(...);

+

+Now write all the required image data by calling jpeg_write_scanlines()

+one or more times.  You can pass one or more scanlines in each call, up

+to the total image height.  In most applications it is convenient to pass

+just one or a few scanlines at a time.  The expected format for the passed

+data is discussed under "Data formats", above.

+

+Image data should be written in top-to-bottom scanline order.  The JPEG spec

+contains some weasel wording about how top and bottom are application-defined

+terms (a curious interpretation of the English language...) but if you want

+your files to be compatible with everyone else's, you WILL use top-to-bottom

+order.  If the source data must be read in bottom-to-top order, you can use

+the JPEG library's virtual array mechanism to invert the data efficiently.

+Examples of this can be found in the sample application cjpeg.

+

+The library maintains a count of the number of scanlines written so far

+in the next_scanline field of the JPEG object.  Usually you can just use

+this variable as the loop counter, so that the loop test looks like

+"while (cinfo.next_scanline < cinfo.image_height)".

+

+Code for this step depends heavily on the way that you store the source data.

+example.c shows the following code for the case of a full-size 2-D source

+array containing 3-byte RGB pixels:

+

+        JSAMPROW row_pointer[1];        /* pointer to a single row */

+        int row_stride;                 /* physical row width in buffer */

+

+        row_stride = image_width * 3;   /* JSAMPLEs per row in image_buffer */

+

+        while (cinfo.next_scanline < cinfo.image_height) {

+            row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride];

+            jpeg_write_scanlines(&cinfo, row_pointer, 1);

+        }

+

+jpeg_write_scanlines() returns the number of scanlines actually written.

+This will normally be equal to the number passed in, so you can usually

+ignore the return value.  It is different in just two cases:

+  * If you try to write more scanlines than the declared image height,

+    the additional scanlines are ignored.

+  * If you use a suspending data destination manager, output buffer overrun

+    will cause the compressor to return before accepting all the passed lines.

+    This feature is discussed under "I/O suspension", below.  The normal

+    stdio destination manager will NOT cause this to happen.

+In any case, the return value is the same as the change in the value of

+next_scanline.

+

+

+6. jpeg_finish_compress(...);

+

+After all the image data has been written, call jpeg_finish_compress() to

+complete the compression cycle.  This step is ESSENTIAL to ensure that the

+last bufferload of data is written to the data destination.

+jpeg_finish_compress() also releases working memory associated with the JPEG

+object.

+

+Typical code:

+

+        jpeg_finish_compress(&cinfo);

+

+If using the stdio destination manager, don't forget to close the output

+stdio stream (if necessary) afterwards.

+

+If you have requested a multi-pass operating mode, such as Huffman code

+optimization, jpeg_finish_compress() will perform the additional passes using

+data buffered by the first pass.  In this case jpeg_finish_compress() may take

+quite a while to complete.  With the default compression parameters, this will

+not happen.

+

+It is an error to call jpeg_finish_compress() before writing the necessary

+total number of scanlines.  If you wish to abort compression, call

+jpeg_abort() as discussed below.

+

+After completing a compression cycle, you may dispose of the JPEG object

+as discussed next, or you may use it to compress another image.  In that case

+return to step 2, 3, or 4 as appropriate.  If you do not change the

+destination manager, the new datastream will be written to the same target.

+If you do not change any JPEG parameters, the new datastream will be written

+with the same parameters as before.  Note that you can change the input image

+dimensions freely between cycles, but if you change the input colorspace, you

+should call jpeg_set_defaults() to adjust for the new colorspace; and then

+you'll need to repeat all of step 3.

+

+

+7. Release the JPEG compression object.

+

+When you are done with a JPEG compression object, destroy it by calling

+jpeg_destroy_compress().  This will free all subsidiary memory (regardless of

+the previous state of the object).  Or you can call jpeg_destroy(), which

+works for either compression or decompression objects --- this may be more

+convenient if you are sharing code between compression and decompression

+cases.  (Actually, these routines are equivalent except for the declared type

+of the passed pointer.  To avoid gripes from ANSI C compilers, jpeg_destroy()

+should be passed a j_common_ptr.)

+

+If you allocated the jpeg_compress_struct structure from malloc(), freeing

+it is your responsibility --- jpeg_destroy() won't.  Ditto for the error

+handler structure.

+

+Typical code:

+

+        jpeg_destroy_compress(&cinfo);

+

+

+8. Aborting.

+

+If you decide to abort a compression cycle before finishing, you can clean up

+in either of two ways:

+

+* If you don't need the JPEG object any more, just call

+  jpeg_destroy_compress() or jpeg_destroy() to release memory.  This is

+  legitimate at any point after calling jpeg_create_compress() --- in fact,

+  it's safe even if jpeg_create_compress() fails.

+

+* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call

+  jpeg_abort() which works on both compression and decompression objects.

+  This will return the object to an idle state, releasing any working memory.

+  jpeg_abort() is allowed at any time after successful object creation.

+

+Note that cleaning up the data destination, if required, is your

+responsibility; neither of these routines will call term_destination().

+(See "Compressed data handling", below, for more about that.)

+

+jpeg_destroy() and jpeg_abort() are the only safe calls to make on a JPEG

+object that has reported an error by calling error_exit (see "Error handling"

+for more info).  The internal state of such an object is likely to be out of

+whack.  Either of these two routines will return the object to a known state.

+

+

+Decompression details

+---------------------

+

+Here we revisit the JPEG decompression outline given in the overview.

+

+1. Allocate and initialize a JPEG decompression object.

+

+This is just like initialization for compression, as discussed above,

+except that the object is a "struct jpeg_decompress_struct" and you

+call jpeg_create_decompress().  Error handling is exactly the same.

+

+Typical code:

+

+        struct jpeg_decompress_struct cinfo;

+        struct jpeg_error_mgr jerr;

+        ...

+        cinfo.err = jpeg_std_error(&jerr);

+        jpeg_create_decompress(&cinfo);

+

+(Both here and in the IJG code, we usually use variable name "cinfo" for

+both compression and decompression objects.)

+

+

+2. Specify the source of the compressed data (eg, a file).

+

+As previously mentioned, the JPEG library reads compressed data from a "data

+source" module.  The library includes one data source module which knows how

+to read from a stdio stream.  You can use your own source module if you want

+to do something else, as discussed later.

+

+If you use the standard source module, you must open the source stdio stream

+beforehand.  Typical code for this step looks like:

+

+        FILE * infile;

+        ...

+        if ((infile = fopen(filename, "rb")) == NULL) {

+            fprintf(stderr, "can't open %s\n", filename);

+            exit(1);

+        }

+        jpeg_stdio_src(&cinfo, infile);

+

+where the last line invokes the standard source module.

+

+WARNING: it is critical that the binary compressed data be read unchanged.

+On non-Unix systems the stdio library may perform newline translation or

+otherwise corrupt binary data.  To suppress this behavior, you may need to use

+a "b" option to fopen (as shown above), or use setmode() or another routine to

+put the stdio stream in binary mode.  See cjpeg.c and djpeg.c for code that

+has been found to work on many systems.

+

+You may not change the data source between calling jpeg_read_header() and

+jpeg_finish_decompress().  If you wish to read a series of JPEG images from

+a single source file, you should repeat the jpeg_read_header() to

+jpeg_finish_decompress() sequence without reinitializing either the JPEG

+object or the data source module; this prevents buffered input data from

+being discarded.

+

+

+3. Call jpeg_read_header() to obtain image info.

+

+Typical code for this step is just

+

+        jpeg_read_header(&cinfo, TRUE);

+

+This will read the source datastream header markers, up to the beginning

+of the compressed data proper.  On return, the image dimensions and other

+info have been stored in the JPEG object.  The application may wish to

+consult this information before selecting decompression parameters.

+

+More complex code is necessary if

+  * A suspending data source is used --- in that case jpeg_read_header()

+    may return before it has read all the header data.  See "I/O suspension",

+    below.  The normal stdio source manager will NOT cause this to happen.

+  * Abbreviated JPEG files are to be processed --- see the section on

+    abbreviated datastreams.  Standard applications that deal only in

+    interchange JPEG files need not be concerned with this case either.

+

+It is permissible to stop at this point if you just wanted to find out the

+image dimensions and other header info for a JPEG file.  In that case,

+call jpeg_destroy() when you are done with the JPEG object, or call

+jpeg_abort() to return it to an idle state before selecting a new data

+source and reading another header.

+

+

+4. Set parameters for decompression.

+

+jpeg_read_header() sets appropriate default decompression parameters based on

+the properties of the image (in particular, its colorspace).  However, you

+may well want to alter these defaults before beginning the decompression.

+For example, the default is to produce full color output from a color file.

+If you want colormapped output you must ask for it.  Other options allow the

+returned image to be scaled and allow various speed/quality tradeoffs to be

+selected.  "Decompression parameter selection", below, gives details.

+

+If the defaults are appropriate, nothing need be done at this step.

+

+Note that all default values are set by each call to jpeg_read_header().

+If you reuse a decompression object, you cannot expect your parameter

+settings to be preserved across cycles, as you can for compression.

+You must set desired parameter values each time.

+

+

+5. jpeg_start_decompress(...);

+

+Once the parameter values are satisfactory, call jpeg_start_decompress() to

+begin decompression.  This will initialize internal state, allocate working

+memory, and prepare for returning data.

+

+Typical code is just

+

+        jpeg_start_decompress(&cinfo);

+

+If you have requested a multi-pass operating mode, such as 2-pass color

+quantization, jpeg_start_decompress() will do everything needed before data

+output can begin.  In this case jpeg_start_decompress() may take quite a while

+to complete.  With a single-scan (non progressive) JPEG file and default

+decompression parameters, this will not happen; jpeg_start_decompress() will

+return quickly.

+

+After this call, the final output image dimensions, including any requested

+scaling, are available in the JPEG object; so is the selected colormap, if

+colormapped output has been requested.  Useful fields include

+

+        output_width            image width and height, as scaled

+        output_height

+        out_color_components    # of color components in out_color_space

+        output_components       # of color components returned per pixel

+        colormap                the selected colormap, if any

+        actual_number_of_colors         number of entries in colormap

+

+output_components is 1 (a colormap index) when quantizing colors; otherwise it

+equals out_color_components.  It is the number of JSAMPLE values that will be

+emitted per pixel in the output arrays.

+

+Typically you will need to allocate data buffers to hold the incoming image.

+You will need output_width * output_components JSAMPLEs per scanline in your

+output buffer, and a total of output_height scanlines will be returned.

+

+Note: if you are using the JPEG library's internal memory manager to allocate

+data buffers (as djpeg does), then the manager's protocol requires that you

+request large buffers *before* calling jpeg_start_decompress().  This is a

+little tricky since the output_XXX fields are not normally valid then.  You

+can make them valid by calling jpeg_calc_output_dimensions() after setting the

+relevant parameters (scaling, output color space, and quantization flag).

+

+

+6. while (scan lines remain to be read)

+        jpeg_read_scanlines(...);

+

+Now you can read the decompressed image data by calling jpeg_read_scanlines()

+one or more times.  At each call, you pass in the maximum number of scanlines

+to be read (ie, the height of your working buffer); jpeg_read_scanlines()

+will return up to that many lines.  The return value is the number of lines

+actually read.  The format of the returned data is discussed under "Data

+formats", above.  Don't forget that grayscale and color JPEGs will return

+different data formats!

+

+Image data is returned in top-to-bottom scanline order.  If you must write

+out the image in bottom-to-top order, you can use the JPEG library's virtual

+array mechanism to invert the data efficiently.  Examples of this can be

+found in the sample application djpeg.

+

+The library maintains a count of the number of scanlines returned so far

+in the output_scanline field of the JPEG object.  Usually you can just use

+this variable as the loop counter, so that the loop test looks like

+"while (cinfo.output_scanline < cinfo.output_height)".  (Note that the test

+should NOT be against image_height, unless you never use scaling.  The

+image_height field is the height of the original unscaled image.)

+The return value always equals the change in the value of output_scanline.

+

+If you don't use a suspending data source, it is safe to assume that

+jpeg_read_scanlines() reads at least one scanline per call, until the

+bottom of the image has been reached.

+

+If you use a buffer larger than one scanline, it is NOT safe to assume that

+jpeg_read_scanlines() fills it.  (The current implementation returns only a

+few scanlines per call, no matter how large a buffer you pass.)  So you must

+always provide a loop that calls jpeg_read_scanlines() repeatedly until the

+whole image has been read.

+

+

+7. jpeg_finish_decompress(...);

+

+After all the image data has been read, call jpeg_finish_decompress() to

+complete the decompression cycle.  This causes working memory associated

+with the JPEG object to be released.

+

+Typical code:

+

+        jpeg_finish_decompress(&cinfo);

+

+If using the stdio source manager, don't forget to close the source stdio

+stream if necessary.

+

+It is an error to call jpeg_finish_decompress() before reading the correct

+total number of scanlines.  If you wish to abort decompression, call

+jpeg_abort() as discussed below.

+

+After completing a decompression cycle, you may dispose of the JPEG object as

+discussed next, or you may use it to decompress another image.  In that case

+return to step 2 or 3 as appropriate.  If you do not change the source

+manager, the next image will be read from the same source.

+

+

+8. Release the JPEG decompression object.

+

+When you are done with a JPEG decompression object, destroy it by calling

+jpeg_destroy_decompress() or jpeg_destroy().  The previous discussion of

+destroying compression objects applies here too.

+

+Typical code:

+

+        jpeg_destroy_decompress(&cinfo);

+

+9. Aborting.

+

+You can abort a decompression cycle by calling jpeg_destroy_decompress() or

+jpeg_destroy() if you don't need the JPEG object any more, or

+jpeg_abort_decompress() or jpeg_abort() if you want to reuse the object.

+The previous discussion of aborting compression cycles applies here too.

+

+

+Mechanics of usage: include files, linking, etc

+-----------------------------------------------

+

+Applications using the JPEG library should include the header file jpeglib.h

+to obtain declarations of data types and routines.  Before including

+jpeglib.h, include system headers that define at least the typedefs FILE and

+size_t.  On ANSI-conforming systems, including <stdio.h> is sufficient; on

+older Unix systems, you may need <sys/types.h> to define size_t.

+

+If the application needs to refer to individual JPEG library error codes, also

+include jerror.h to define those symbols.

+

+jpeglib.h indirectly includes the files jconfig.h and jmorecfg.h.  If you are

+installing the JPEG header files in a system directory, you will want to

+install all four files: jpeglib.h, jerror.h, jconfig.h, jmorecfg.h.

+

+The most convenient way to include the JPEG code into your executable program

+is to prepare a library file ("libjpeg.a", or a corresponding name on non-Unix

+machines) and reference it at your link step.  If you use only half of the

+library (only compression or only decompression), only that much code will be

+included from the library, unless your linker is hopelessly brain-damaged.

+The supplied makefiles build libjpeg.a automatically (see install.txt).

+

+While you can build the JPEG library as a shared library if the whim strikes

+you, we don't really recommend it.  The trouble with shared libraries is that

+at some point you'll probably try to substitute a new version of the library

+without recompiling the calling applications.  That generally doesn't work

+because the parameter struct declarations usually change with each new

+version.  In other words, the library's API is *not* guaranteed binary

+compatible across versions; we only try to ensure source-code compatibility.

+(In hindsight, it might have been smarter to hide the parameter structs from

+applications and introduce a ton of access functions instead.  Too late now,

+however.)

+

+On some systems your application may need to set up a signal handler to ensure

+that temporary files are deleted if the program is interrupted.  This is most

+critical if you are on MS-DOS and use the jmemdos.c memory manager back end;

+it will try to grab extended memory for temp files, and that space will NOT be

+freed automatically.  See cjpeg.c or djpeg.c for an example signal handler.

+

+It may be worth pointing out that the core JPEG library does not actually

+require the stdio library: only the default source/destination managers and

+error handler need it.  You can use the library in a stdio-less environment

+if you replace those modules and use jmemnobs.c (or another memory manager of

+your own devising).  More info about the minimum system library requirements

+may be found in jinclude.h.

+

+

+ADVANCED FEATURES

+=================

+

+Compression parameter selection

+-------------------------------

+

+This section describes all the optional parameters you can set for JPEG

+compression, as well as the "helper" routines provided to assist in this

+task.  Proper setting of some parameters requires detailed understanding

+of the JPEG standard; if you don't know what a parameter is for, it's best

+not to mess with it!  See REFERENCES in the README file for pointers to

+more info about JPEG.

+

+It's a good idea to call jpeg_set_defaults() first, even if you plan to set

+all the parameters; that way your code is more likely to work with future JPEG

+libraries that have additional parameters.  For the same reason, we recommend

+you use a helper routine where one is provided, in preference to twiddling

+cinfo fields directly.

+

+The helper routines are:

+

+jpeg_set_defaults (j_compress_ptr cinfo)

+        This routine sets all JPEG parameters to reasonable defaults, using

+        only the input image's color space (field in_color_space, which must

+        already be set in cinfo).  Many applications will only need to use

+        this routine and perhaps jpeg_set_quality().

+

+jpeg_set_colorspace (j_compress_ptr cinfo, J_COLOR_SPACE colorspace)

+        Sets the JPEG file's colorspace (field jpeg_color_space) as specified,

+        and sets other color-space-dependent parameters appropriately.  See

+        "Special color spaces", below, before using this.  A large number of

+        parameters, including all per-component parameters, are set by this

+        routine; if you want to twiddle individual parameters you should call

+        jpeg_set_colorspace() before rather than after.

+

+jpeg_default_colorspace (j_compress_ptr cinfo)

+        Selects an appropriate JPEG colorspace based on cinfo->in_color_space,

+        and calls jpeg_set_colorspace().  This is actually a subroutine of

+        jpeg_set_defaults().  It's broken out in case you want to change

+        just the colorspace-dependent JPEG parameters.

+

+jpeg_set_quality (j_compress_ptr cinfo, int quality, boolean force_baseline)

+        Constructs JPEG quantization tables appropriate for the indicated

+        quality setting.  The quality value is expressed on the 0..100 scale

+        recommended by IJG (cjpeg's "-quality" switch uses this routine).

+        Note that the exact mapping from quality values to tables may change

+        in future IJG releases as more is learned about DCT quantization.

+        If the force_baseline parameter is TRUE, then the quantization table

+        entries are constrained to the range 1..255 for full JPEG baseline

+        compatibility.  In the current implementation, this only makes a

+        difference for quality settings below 25, and it effectively prevents

+        very small/low quality files from being generated.  The IJG decoder

+        is capable of reading the non-baseline files generated at low quality

+        settings when force_baseline is FALSE, but other decoders may not be.

+

+jpeg_set_linear_quality (j_compress_ptr cinfo, int scale_factor,

+                         boolean force_baseline)

+        Same as jpeg_set_quality() except that the generated tables are the

+        sample tables given in the JPEC spec section K.1, multiplied by the

+        specified scale factor (which is expressed as a percentage; thus

+        scale_factor = 100 reproduces the spec's tables).  Note that larger

+        scale factors give lower quality.  This entry point is useful for

+        conforming to the Adobe PostScript DCT conventions, but we do not

+        recommend linear scaling as a user-visible quality scale otherwise.

+        force_baseline again constrains the computed table entries to 1..255.

+

+int jpeg_quality_scaling (int quality)

+        Converts a value on the IJG-recommended quality scale to a linear

+        scaling percentage.  Note that this routine may change or go away

+        in future releases --- IJG may choose to adopt a scaling method that

+        can't be expressed as a simple scalar multiplier, in which case the

+        premise of this routine collapses.  Caveat user.

+

+jpeg_default_qtables (j_compress_ptr cinfo, boolean force_baseline)

+        Set default quantization tables with linear q_scale_factor[] values

+        (see below).

+

+jpeg_add_quant_table (j_compress_ptr cinfo, int which_tbl,

+                      const unsigned int *basic_table,

+                      int scale_factor, boolean force_baseline)

+        Allows an arbitrary quantization table to be created.  which_tbl

+        indicates which table slot to fill.  basic_table points to an array

+        of 64 unsigned ints given in normal array order.  These values are

+        multiplied by scale_factor/100 and then clamped to the range 1..65535

+        (or to 1..255 if force_baseline is TRUE).

+        CAUTION: prior to library version 6a, jpeg_add_quant_table expected

+        the basic table to be given in JPEG zigzag order.  If you need to

+        write code that works with either older or newer versions of this

+        routine, you must check the library version number.  Something like

+        "#if JPEG_LIB_VERSION >= 61" is the right test.

+

+jpeg_simple_progression (j_compress_ptr cinfo)

+        Generates a default scan script for writing a progressive-JPEG file.

+        This is the recommended method of creating a progressive file,

+        unless you want to make a custom scan sequence.  You must ensure that

+        the JPEG color space is set correctly before calling this routine.

+

+

+Compression parameters (cinfo fields) include:

+

+int block_size

+        Set DCT block size.  All N from 1 to 16 are possible.

+        Default is 8 (baseline format).

+        Larger values produce higher compression,

+        smaller values produce higher quality.

+        An exact DCT stage is possible with 1 or 2.

+        With the default quality of 75 and default Luminance qtable

+        the DCT+Quantization stage is lossless for value 1.

+        Note that values other than 8 require a SmartScale capable decoder,

+        introduced with IJG JPEG 8.  Setting the block_size parameter for

+        compression works with version 8c and later.

+

+J_DCT_METHOD dct_method

+        Selects the algorithm used for the DCT step.  Choices are:

+                JDCT_ISLOW: slow but accurate integer algorithm

+                JDCT_IFAST: faster, less accurate integer method

+                JDCT_FLOAT: floating-point method

+                JDCT_DEFAULT: default method (normally JDCT_ISLOW)

+                JDCT_FASTEST: fastest method (normally JDCT_IFAST)

+        The FLOAT method is very slightly more accurate than the ISLOW method,

+        but may give different results on different machines due to varying

+        roundoff behavior.  The integer methods should give the same results

+        on all machines.  On machines with sufficiently fast FP hardware, the

+        floating-point method may also be the fastest.  The IFAST method is

+        considerably less accurate than the other two; its use is not

+        recommended if high quality is a concern.  JDCT_DEFAULT and

+        JDCT_FASTEST are macros configurable by each installation.

+

+unsigned int scale_num, scale_denom

+        Scale the image by the fraction scale_num/scale_denom.  Default is

+        1/1, or no scaling.  Currently, the supported scaling ratios are

+        M/N with all N from 1 to 16, where M is the destination DCT size,

+        which is 8 by default (see block_size parameter above).

+        (The library design allows for arbitrary scaling ratios but this

+        is not likely to be implemented any time soon.)

+

+J_COLOR_SPACE jpeg_color_space

+int num_components

+        The JPEG color space and corresponding number of components; see

+        "Special color spaces", below, for more info.  We recommend using

+        jpeg_set_color_space() if you want to change these.

+

+boolean optimize_coding

+        TRUE causes the compressor to compute optimal Huffman coding tables

+        for the image.  This requires an extra pass over the data and

+        therefore costs a good deal of space and time.  The default is

+        FALSE, which tells the compressor to use the supplied or default

+        Huffman tables.  In most cases optimal tables save only a few percent

+        of file size compared to the default tables.  Note that when this is

+        TRUE, you need not supply Huffman tables at all, and any you do

+        supply will be overwritten.

+

+unsigned int restart_interval

+int restart_in_rows

+        To emit restart markers in the JPEG file, set one of these nonzero.

+        Set restart_interval to specify the exact interval in MCU blocks.

+        Set restart_in_rows to specify the interval in MCU rows.  (If

+        restart_in_rows is not 0, then restart_interval is set after the

+        image width in MCUs is computed.)  Defaults are zero (no restarts).

+        One restart marker per MCU row is often a good choice.

+        NOTE: the overhead of restart markers is higher in grayscale JPEG

+        files than in color files, and MUCH higher in progressive JPEGs.

+        If you use restarts, you may want to use larger intervals in those

+        cases.

+

+const jpeg_scan_info * scan_info

+int num_scans

+        By default, scan_info is NULL; this causes the compressor to write a

+        single-scan sequential JPEG file.  If not NULL, scan_info points to

+        an array of scan definition records of length num_scans.  The

+        compressor will then write a JPEG file having one scan for each scan

+        definition record.  This is used to generate noninterleaved or

+        progressive JPEG files.  The library checks that the scan array

+        defines a valid JPEG scan sequence.  (jpeg_simple_progression creates

+        a suitable scan definition array for progressive JPEG.)  This is

+        discussed further under "Progressive JPEG support".

+

+boolean do_fancy_downsampling

+        If TRUE, use direct DCT scaling with DCT size > 8 for downsampling

+        of chroma components.

+        If FALSE, use only DCT size <= 8 and simple separate downsampling.

+        Default is TRUE.

+        For better image stability in multiple generation compression cycles

+        it is preferable that this value matches the corresponding

+        do_fancy_upsampling value in decompression.

+

+int smoothing_factor

+        If non-zero, the input image is smoothed; the value should be 1 for

+        minimal smoothing to 100 for maximum smoothing.  Consult jcsample.c

+        for details of the smoothing algorithm.  The default is zero.

+

+boolean write_JFIF_header

+        If TRUE, a JFIF APP0 marker is emitted.  jpeg_set_defaults() and

+        jpeg_set_colorspace() set this TRUE if a JFIF-legal JPEG color space

+        (ie, YCbCr or grayscale) is selected, otherwise FALSE.

+

+UINT8 JFIF_major_version

+UINT8 JFIF_minor_version

+        The version number to be written into the JFIF marker.

+        jpeg_set_defaults() initializes the version to 1.01 (major=minor=1).

+        You should set it to 1.02 (major=1, minor=2) if you plan to write

+        any JFIF 1.02 extension markers.

+

+UINT8 density_unit

+UINT16 X_density

+UINT16 Y_density

+        The resolution information to be written into the JFIF marker;

+        not used otherwise.  density_unit may be 0 for unknown,

+        1 for dots/inch, or 2 for dots/cm.  The default values are 0,1,1

+        indicating square pixels of unknown size.

+

+boolean write_Adobe_marker

+        If TRUE, an Adobe APP14 marker is emitted.  jpeg_set_defaults() and

+        jpeg_set_colorspace() set this TRUE if JPEG color space RGB, CMYK,

+        or YCCK is selected, otherwise FALSE.  It is generally a bad idea

+        to set both write_JFIF_header and write_Adobe_marker.  In fact,

+        you probably shouldn't change the default settings at all --- the

+        default behavior ensures that the JPEG file's color space can be

+        recognized by the decoder.

+

+JQUANT_TBL * quant_tbl_ptrs[NUM_QUANT_TBLS]

+        Pointers to coefficient quantization tables, one per table slot,

+        or NULL if no table is defined for a slot.  Usually these should

+        be set via one of the above helper routines; jpeg_add_quant_table()

+        is general enough to define any quantization table.  The other

+        routines will set up table slot 0 for luminance quality and table

+        slot 1 for chrominance.

+

+int q_scale_factor[NUM_QUANT_TBLS]

+        Linear quantization scaling factors (percentage, initialized 100)

+        for use with jpeg_default_qtables().

+        See rdswitch.c and cjpeg.c for an example of usage.

+        Note that the q_scale_factor[] fields are the "linear" scales, so you

+        have to convert from user-defined ratings via jpeg_quality_scaling().

+        Here is an example code which corresponds to cjpeg -quality 90,70:

+

+                jpeg_set_defaults(cinfo);

+

+                /* Set luminance quality 90. */

+                cinfo->q_scale_factor[0] = jpeg_quality_scaling(90);

+                /* Set chrominance quality 70. */

+                cinfo->q_scale_factor[1] = jpeg_quality_scaling(70);

+

+                jpeg_default_qtables(cinfo, force_baseline);

+

+        CAUTION: You must also set 1x1 subsampling for efficient separate

+        color quality selection, since the default value used by library

+        is 2x2:

+

+                cinfo->comp_info[0].v_samp_factor = 1;

+                cinfo->comp_info[0].h_samp_factor = 1;

+

+JHUFF_TBL * dc_huff_tbl_ptrs[NUM_HUFF_TBLS]

+JHUFF_TBL * ac_huff_tbl_ptrs[NUM_HUFF_TBLS]

+        Pointers to Huffman coding tables, one per table slot, or NULL if

+        no table is defined for a slot.  Slots 0 and 1 are filled with the

+        JPEG sample tables by jpeg_set_defaults().  If you need to allocate

+        more table structures, jpeg_alloc_huff_table() may be used.

+        Note that optimal Huffman tables can be computed for an image

+        by setting optimize_coding, as discussed above; there's seldom

+        any need to mess with providing your own Huffman tables.

+

+

+The actual dimensions of the JPEG image that will be written to the file are

+given by the following fields.  These are computed from the input image

+dimensions and the compression parameters by jpeg_start_compress().  You can

+also call jpeg_calc_jpeg_dimensions() to obtain the values that will result

+from the current parameter settings.  This can be useful if you are trying

+to pick a scaling ratio that will get close to a desired target size.

+

+JDIMENSION jpeg_width           Actual dimensions of output image.

+JDIMENSION jpeg_height

+

+

+Per-component parameters are stored in the struct cinfo.comp_info[i] for

+component number i.  Note that components here refer to components of the

+JPEG color space, *not* the source image color space.  A suitably large

+comp_info[] array is allocated by jpeg_set_defaults(); if you choose not

+to use that routine, it's up to you to allocate the array.

+

+int component_id

+        The one-byte identifier code to be recorded in the JPEG file for

+        this component.  For the standard color spaces, we recommend you

+        leave the default values alone.

+

+int h_samp_factor

+int v_samp_factor

+        Horizontal and vertical sampling factors for the component; must

+        be 1..4 according to the JPEG standard.  Note that larger sampling

+        factors indicate a higher-resolution component; many people find

+        this behavior quite unintuitive.  The default values are 2,2 for

+        luminance components and 1,1 for chrominance components, except

+        for grayscale where 1,1 is used.

+

+int quant_tbl_no

+        Quantization table number for component.  The default value is

+        0 for luminance components and 1 for chrominance components.

+

+int dc_tbl_no

+int ac_tbl_no

+        DC and AC entropy coding table numbers.  The default values are

+        0 for luminance components and 1 for chrominance components.

+

+int component_index

+        Must equal the component's index in comp_info[].  (Beginning in

+        release v6, the compressor library will fill this in automatically;

+        you don't have to.)

+

+

+Decompression parameter selection

+---------------------------------

+

+Decompression parameter selection is somewhat simpler than compression

+parameter selection, since all of the JPEG internal parameters are

+recorded in the source file and need not be supplied by the application.

+(Unless you are working with abbreviated files, in which case see

+"Abbreviated datastreams", below.)  Decompression parameters control

+the postprocessing done on the image to deliver it in a format suitable

+for the application's use.  Many of the parameters control speed/quality

+tradeoffs, in which faster decompression may be obtained at the price of

+a poorer-quality image.  The defaults select the highest quality (slowest)

+processing.

+

+The following fields in the JPEG object are set by jpeg_read_header() and

+may be useful to the application in choosing decompression parameters:

+

+JDIMENSION image_width                  Width and height of image

+JDIMENSION image_height

+int num_components                      Number of color components

+J_COLOR_SPACE jpeg_color_space          Colorspace of image

+boolean saw_JFIF_marker                 TRUE if a JFIF APP0 marker was seen

+  UINT8 JFIF_major_version              Version information from JFIF marker

+  UINT8 JFIF_minor_version

+  UINT8 density_unit                    Resolution data from JFIF marker

+  UINT16 X_density

+  UINT16 Y_density

+boolean saw_Adobe_marker                TRUE if an Adobe APP14 marker was seen

+  UINT8 Adobe_transform                 Color transform code from Adobe marker

+

+The JPEG color space, unfortunately, is something of a guess since the JPEG

+standard proper does not provide a way to record it.  In practice most files

+adhere to the JFIF or Adobe conventions, and the decoder will recognize these

+correctly.  See "Special color spaces", below, for more info.

+

+

+The decompression parameters that determine the basic properties of the

+returned image are:

+

+J_COLOR_SPACE out_color_space

+        Output color space.  jpeg_read_header() sets an appropriate default

+        based on jpeg_color_space; typically it will be RGB or grayscale.

+        The application can change this field to request output in a different

+        colorspace.  For example, set it to JCS_GRAYSCALE to get grayscale

+        output from a color file.  (This is useful for previewing: grayscale

+        output is faster than full color since the color components need not

+        be processed.)  Note that not all possible color space transforms are

+        currently implemented; you may need to extend jdcolor.c if you want an

+        unusual conversion.

+

+unsigned int scale_num, scale_denom

+        Scale the image by the fraction scale_num/scale_denom.  Currently,

+        the supported scaling ratios are M/N with all M from 1 to 16, where

+        N is the source DCT size, which is 8 for baseline JPEG.  (The library

+        design allows for arbitrary scaling ratios but this is not likely

+        to be implemented any time soon.)  The values are initialized by

+        jpeg_read_header() with the source DCT size.  For baseline JPEG

+        this is 8/8.  If you change only the scale_num value while leaving

+        the other unchanged, then this specifies the DCT scaled size to be

+        applied on the given input.  For baseline JPEG this is equivalent

+        to M/8 scaling, since the source DCT size for baseline JPEG is 8.

+        Smaller scaling ratios permit significantly faster decoding since

+        fewer pixels need be processed and a simpler IDCT method can be used.

+

+boolean quantize_colors

+        If set TRUE, colormapped output will be delivered.  Default is FALSE,

+        meaning that full-color output will be delivered.

+

+The next three parameters are relevant only if quantize_colors is TRUE.

+

+int desired_number_of_colors

+        Maximum number of colors to use in generating a library-supplied color

+        map (the actual number of colors is returned in a different field).

+        Default 256.  Ignored when the application supplies its own color map.

+

+boolean two_pass_quantize

+        If TRUE, an extra pass over the image is made to select a custom color

+        map for the image.  This usually looks a lot better than the one-size-

+        fits-all colormap that is used otherwise.  Default is TRUE.  Ignored

+        when the application supplies its own color map.

+

+J_DITHER_MODE dither_mode

+        Selects color dithering method.  Supported values are:

+                JDITHER_NONE    no dithering: fast, very low quality

+                JDITHER_ORDERED ordered dither: moderate speed and quality

+                JDITHER_FS      Floyd-Steinberg dither: slow, high quality

+        Default is JDITHER_FS.  (At present, ordered dither is implemented

+        only in the single-pass, standard-colormap case.  If you ask for

+        ordered dither when two_pass_quantize is TRUE or when you supply

+        an external color map, you'll get F-S dithering.)

+

+When quantize_colors is TRUE, the target color map is described by the next

+two fields.  colormap is set to NULL by jpeg_read_header().  The application

+can supply a color map by setting colormap non-NULL and setting

+actual_number_of_colors to the map size.  Otherwise, jpeg_start_decompress()

+selects a suitable color map and sets these two fields itself.

+[Implementation restriction: at present, an externally supplied colormap is

+only accepted for 3-component output color spaces.]

+

+JSAMPARRAY colormap

+        The color map, represented as a 2-D pixel array of out_color_components

+        rows and actual_number_of_colors columns.  Ignored if not quantizing.

+        CAUTION: if the JPEG library creates its own colormap, the storage

+        pointed to by this field is released by jpeg_finish_decompress().

+        Copy the colormap somewhere else first, if you want to save it.

+

+int actual_number_of_colors

+        The number of colors in the color map.

+

+Additional decompression parameters that the application may set include:

+

+J_DCT_METHOD dct_method

+        Selects the algorithm used for the DCT step.  Choices are the same

+        as described above for compression.

+

+boolean do_fancy_upsampling

+        If TRUE, use direct DCT scaling with DCT size > 8 for upsampling

+        of chroma components.

+        If FALSE, use only DCT size <= 8 and simple separate upsampling.

+        Default is TRUE.

+        For better image stability in multiple generation compression cycles

+        it is preferable that this value matches the corresponding

+        do_fancy_downsampling value in compression.

+

+boolean do_block_smoothing

+        If TRUE, interblock smoothing is applied in early stages of decoding

+        progressive JPEG files; if FALSE, not.  Default is TRUE.  Early

+        progression stages look "fuzzy" with smoothing, "blocky" without.

+        In any case, block smoothing ceases to be applied after the first few

+        AC coefficients are known to full accuracy, so it is relevant only

+        when using buffered-image mode for progressive images.

+

+boolean enable_1pass_quant

+boolean enable_external_quant

+boolean enable_2pass_quant

+        These are significant only in buffered-image mode, which is

+        described in its own section below.

+

+

+The output image dimensions are given by the following fields.  These are

+computed from the source image dimensions and the decompression parameters

+by jpeg_start_decompress().  You can also call jpeg_calc_output_dimensions()

+to obtain the values that will result from the current parameter settings.

+This can be useful if you are trying to pick a scaling ratio that will get

+close to a desired target size.  It's also important if you are using the

+JPEG library's memory manager to allocate output buffer space, because you

+are supposed to request such buffers *before* jpeg_start_decompress().

+

+JDIMENSION output_width         Actual dimensions of output image.

+JDIMENSION output_height

+int out_color_components        Number of color components in out_color_space.

+int output_components           Number of color components returned.

+int rec_outbuf_height           Recommended height of scanline buffer.

+

+When quantizing colors, output_components is 1, indicating a single color map

+index per pixel.  Otherwise it equals out_color_components.  The output arrays

+are required to be output_width * output_components JSAMPLEs wide.

+

+rec_outbuf_height is the recommended minimum height (in scanlines) of the

+buffer passed to jpeg_read_scanlines().  If the buffer is smaller, the

+library will still work, but time will be wasted due to unnecessary data

+copying.  In high-quality modes, rec_outbuf_height is always 1, but some

+faster, lower-quality modes set it to larger values (typically 2 to 4).

+If you are going to ask for a high-speed processing mode, you may as well

+go to the trouble of honoring rec_outbuf_height so as to avoid data copying.

+(An output buffer larger than rec_outbuf_height lines is OK, but won't

+provide any material speed improvement over that height.)

+

+

+Special color spaces

+--------------------

+

+The JPEG standard itself is "color blind" and doesn't specify any particular

+color space.  It is customary to convert color data to a luminance/chrominance

+color space before compressing, since this permits greater compression.  The

+existing de-facto JPEG file format standards specify YCbCr or grayscale data

+(JFIF), or grayscale, RGB, YCbCr, CMYK, or YCCK (Adobe).  For special

+applications such as multispectral images, other color spaces can be used,

+but it must be understood that such files will be unportable.

+

+The JPEG library can handle the most common colorspace conversions (namely

+RGB <=> YCbCr and CMYK <=> YCCK).  It can also deal with data of an unknown

+color space, passing it through without conversion.  If you deal extensively

+with an unusual color space, you can easily extend the library to understand

+additional color spaces and perform appropriate conversions.

+

+For compression, the source data's color space is specified by field

+in_color_space.  This is transformed to the JPEG file's color space given

+by jpeg_color_space.  jpeg_set_defaults() chooses a reasonable JPEG color

+space depending on in_color_space, but you can override this by calling

+jpeg_set_colorspace().  Of course you must select a supported transformation.

+jccolor.c currently supports the following transformations:

+        RGB => YCbCr

+        RGB => GRAYSCALE

+        YCbCr => GRAYSCALE

+        CMYK => YCCK

+plus the null transforms: GRAYSCALE => GRAYSCALE, RGB => RGB,

+YCbCr => YCbCr, CMYK => CMYK, YCCK => YCCK, and UNKNOWN => UNKNOWN.

+

+The de-facto file format standards (JFIF and Adobe) specify APPn markers that

+indicate the color space of the JPEG file.  It is important to ensure that

+these are written correctly, or omitted if the JPEG file's color space is not

+one of the ones supported by the de-facto standards.  jpeg_set_colorspace()

+will set the compression parameters to include or omit the APPn markers

+properly, so long as it is told the truth about the JPEG color space.

+For example, if you are writing some random 3-component color space without

+conversion, don't try to fake out the library by setting in_color_space and

+jpeg_color_space to JCS_YCbCr; use JCS_UNKNOWN.  You may want to write an

+APPn marker of your own devising to identify the colorspace --- see "Special

+markers", below.

+

+When told that the color space is UNKNOWN, the library will default to using

+luminance-quality compression parameters for all color components.  You may

+well want to change these parameters.  See the source code for

+jpeg_set_colorspace(), in jcparam.c, for details.

+

+For decompression, the JPEG file's color space is given in jpeg_color_space,

+and this is transformed to the output color space out_color_space.

+jpeg_read_header's setting of jpeg_color_space can be relied on if the file

+conforms to JFIF or Adobe conventions, but otherwise it is no better than a

+guess.  If you know the JPEG file's color space for certain, you can override

+jpeg_read_header's guess by setting jpeg_color_space.  jpeg_read_header also

+selects a default output color space based on (its guess of) jpeg_color_space;

+set out_color_space to override this.  Again, you must select a supported

+transformation.  jdcolor.c currently supports

+        YCbCr => RGB

+        YCbCr => GRAYSCALE

+        RGB => GRAYSCALE

+        GRAYSCALE => RGB

+        YCCK => CMYK

+as well as the null transforms.  (Since GRAYSCALE=>RGB is provided, an

+application can force grayscale JPEGs to look like color JPEGs if it only

+wants to handle one case.)

+

+The two-pass color quantizer, jquant2.c, is specialized to handle RGB data

+(it weights distances appropriately for RGB colors).  You'll need to modify

+the code if you want to use it for non-RGB output color spaces.  Note that

+jquant2.c is used to map to an application-supplied colormap as well as for

+the normal two-pass colormap selection process.

+

+CAUTION: it appears that Adobe Photoshop writes inverted data in CMYK JPEG

+files: 0 represents 100% ink coverage, rather than 0% ink as you'd expect.

+This is arguably a bug in Photoshop, but if you need to work with Photoshop

+CMYK files, you will have to deal with it in your application.  We cannot

+"fix" this in the library by inverting the data during the CMYK<=>YCCK

+transform, because that would break other applications, notably Ghostscript.

+Photoshop versions prior to 3.0 write EPS files containing JPEG-encoded CMYK

+data in the same inverted-YCCK representation used in bare JPEG files, but

+the surrounding PostScript code performs an inversion using the PS image

+operator.  I am told that Photoshop 3.0 will write uninverted YCCK in

+EPS/JPEG files, and will omit the PS-level inversion.  (But the data

+polarity used in bare JPEG files will not change in 3.0.)  In either case,

+the JPEG library must not invert the data itself, or else Ghostscript would

+read these EPS files incorrectly.

+

+

+Error handling

+--------------

+

+When the default error handler is used, any error detected inside the JPEG

+routines will cause a message to be printed on stderr, followed by exit().

+You can supply your own error handling routines to override this behavior

+and to control the treatment of nonfatal warnings and trace/debug messages.

+The file example.c illustrates the most common case, which is to have the

+application regain control after an error rather than exiting.

+

+The JPEG library never writes any message directly; it always goes through

+the error handling routines.  Three classes of messages are recognized:

+  * Fatal errors: the library cannot continue.

+  * Warnings: the library can continue, but the data is corrupt, and a

+    damaged output image is likely to result.

+  * Trace/informational messages.  These come with a trace level indicating

+    the importance of the message; you can control the verbosity of the

+    program by adjusting the maximum trace level that will be displayed.

+

+You may, if you wish, simply replace the entire JPEG error handling module

+(jerror.c) with your own code.  However, you can avoid code duplication by

+only replacing some of the routines depending on the behavior you need.

+This is accomplished by calling jpeg_std_error() as usual, but then overriding

+some of the method pointers in the jpeg_error_mgr struct, as illustrated by

+example.c.

+

+All of the error handling routines will receive a pointer to the JPEG object

+(a j_common_ptr which points to either a jpeg_compress_struct or a

+jpeg_decompress_struct; if you need to tell which, test the is_decompressor

+field).  This struct includes a pointer to the error manager struct in its

+"err" field.  Frequently, custom error handler routines will need to access

+additional data which is not known to the JPEG library or the standard error

+handler.  The most convenient way to do this is to embed either the JPEG

+object or the jpeg_error_mgr struct in a larger structure that contains

+additional fields; then casting the passed pointer provides access to the

+additional fields.  Again, see example.c for one way to do it.  (Beginning

+with IJG version 6b, there is also a void pointer "client_data" in each

+JPEG object, which the application can also use to find related data.

+The library does not touch client_data at all.)

+

+The individual methods that you might wish to override are:

+

+error_exit (j_common_ptr cinfo)

+        Receives control for a fatal error.  Information sufficient to

+        generate the error message has been stored in cinfo->err; call

+        output_message to display it.  Control must NOT return to the caller;

+        generally this routine will exit() or longjmp() somewhere.

+        Typically you would override this routine to get rid of the exit()

+        default behavior.  Note that if you continue processing, you should

+        clean up the JPEG object with jpeg_abort() or jpeg_destroy().

+

+output_message (j_common_ptr cinfo)

+        Actual output of any JPEG message.  Override this to send messages

+        somewhere other than stderr.  Note that this method does not know

+        how to generate a message, only where to send it.

+

+format_message (j_common_ptr cinfo, char * buffer)

+        Constructs a readable error message string based on the error info

+        stored in cinfo->err.  This method is called by output_message.  Few

+        applications should need to override this method.  One possible

+        reason for doing so is to implement dynamic switching of error message

+        language.

+

+emit_message (j_common_ptr cinfo, int msg_level)

+        Decide whether or not to emit a warning or trace message; if so,

+        calls output_message.  The main reason for overriding this method

+        would be to abort on warnings.  msg_level is -1 for warnings,

+        0 and up for trace messages.

+

+Only error_exit() and emit_message() are called from the rest of the JPEG

+library; the other two are internal to the error handler.

+

+The actual message texts are stored in an array of strings which is pointed to

+by the field err->jpeg_message_table.  The messages are numbered from 0 to

+err->last_jpeg_message, and it is these code numbers that are used in the

+JPEG library code.  You could replace the message texts (for instance, with

+messages in French or German) by changing the message table pointer.  See

+jerror.h for the default texts.  CAUTION: this table will almost certainly

+change or grow from one library version to the next.

+

+It may be useful for an application to add its own message texts that are

+handled by the same mechanism.  The error handler supports a second "add-on"

+message table for this purpose.  To define an addon table, set the pointer

+err->addon_message_table and the message numbers err->first_addon_message and

+err->last_addon_message.  If you number the addon messages beginning at 1000

+or so, you won't have to worry about conflicts with the library's built-in

+messages.  See the sample applications cjpeg/djpeg for an example of using

+addon messages (the addon messages are defined in cderror.h).

+

+Actual invocation of the error handler is done via macros defined in jerror.h:

+        ERREXITn(...)   for fatal errors

+        WARNMSn(...)    for corrupt-data warnings

+        TRACEMSn(...)   for trace and informational messages.

+These macros store the message code and any additional parameters into the

+error handler struct, then invoke the error_exit() or emit_message() method.

+The variants of each macro are for varying numbers of additional parameters.

+The additional parameters are inserted into the generated message using

+standard printf() format codes.

+

+See jerror.h and jerror.c for further details.

+

+

+Compressed data handling (source and destination managers)

+----------------------------------------------------------

+

+The JPEG compression library sends its compressed data to a "destination

+manager" module.  The default destination manager just writes the data to a

+memory buffer or to a stdio stream, but you can provide your own manager to

+do something else.  Similarly, the decompression library calls a "source

+manager" to obtain the compressed data; you can provide your own source

+manager if you want the data to come from somewhere other than a memory

+buffer or a stdio stream.

+

+In both cases, compressed data is processed a bufferload at a time: the

+destination or source manager provides a work buffer, and the library invokes

+the manager only when the buffer is filled or emptied.  (You could define a

+one-character buffer to force the manager to be invoked for each byte, but

+that would be rather inefficient.)  The buffer's size and location are

+controlled by the manager, not by the library.  For example, the memory

+source manager just makes the buffer pointer and length point to the original

+data in memory.  In this case the buffer-reload procedure will be invoked

+only if the decompressor ran off the end of the datastream, which would

+indicate an erroneous datastream.

+

+The work buffer is defined as an array of datatype JOCTET, which is generally

+"char" or "unsigned char".  On a machine where char is not exactly 8 bits

+wide, you must define JOCTET as a wider data type and then modify the data

+source and destination modules to transcribe the work arrays into 8-bit units

+on external storage.

+

+A data destination manager struct contains a pointer and count defining the

+next byte to write in the work buffer and the remaining free space:

+

+        JOCTET * next_output_byte;  /* => next byte to write in buffer */

+        size_t free_in_buffer;      /* # of byte spaces remaining in buffer */

+

+The library increments the pointer and decrements the count until the buffer

+is filled.  The manager's empty_output_buffer method must reset the pointer

+and count.  The manager is expected to remember the buffer's starting address

+and total size in private fields not visible to the library.

+

+A data destination manager provides three methods:

+

+init_destination (j_compress_ptr cinfo)

+        Initialize destination.  This is called by jpeg_start_compress()

+        before any data is actually written.  It must initialize

+        next_output_byte and free_in_buffer.  free_in_buffer must be

+        initialized to a positive value.

+

+empty_output_buffer (j_compress_ptr cinfo)

+        This is called whenever the buffer has filled (free_in_buffer

+        reaches zero).  In typical applications, it should write out the

+        *entire* buffer (use the saved start address and buffer length;

+        ignore the current state of next_output_byte and free_in_buffer).

+        Then reset the pointer & count to the start of the buffer, and

+        return TRUE indicating that the buffer has been dumped.

+        free_in_buffer must be set to a positive value when TRUE is

+        returned.  A FALSE return should only be used when I/O suspension is

+        desired (this operating mode is discussed in the next section).

+

+term_destination (j_compress_ptr cinfo)

+        Terminate destination --- called by jpeg_finish_compress() after all

+        data has been written.  In most applications, this must flush any

+        data remaining in the buffer.  Use either next_output_byte or

+        free_in_buffer to determine how much data is in the buffer.

+

+term_destination() is NOT called by jpeg_abort() or jpeg_destroy().  If you

+want the destination manager to be cleaned up during an abort, you must do it

+yourself.

+

+You will also need code to create a jpeg_destination_mgr struct, fill in its

+method pointers, and insert a pointer to the struct into the "dest" field of

+the JPEG compression object.  This can be done in-line in your setup code if

+you like, but it's probably cleaner to provide a separate routine similar to

+the jpeg_stdio_dest() or jpeg_mem_dest() routines of the supplied destination

+managers.

+

+Decompression source managers follow a parallel design, but with some

+additional frammishes.  The source manager struct contains a pointer and count

+defining the next byte to read from the work buffer and the number of bytes

+remaining:

+

+        const JOCTET * next_input_byte; /* => next byte to read from buffer */

+        size_t bytes_in_buffer;         /* # of bytes remaining in buffer */

+

+The library increments the pointer and decrements the count until the buffer

+is emptied.  The manager's fill_input_buffer method must reset the pointer and

+count.  In most applications, the manager must remember the buffer's starting

+address and total size in private fields not visible to the library.

+

+A data source manager provides five methods:

+

+init_source (j_decompress_ptr cinfo)

+        Initialize source.  This is called by jpeg_read_header() before any

+        data is actually read.  Unlike init_destination(), it may leave

+        bytes_in_buffer set to 0 (in which case a fill_input_buffer() call

+        will occur immediately).

+

+fill_input_buffer (j_decompress_ptr cinfo)

+        This is called whenever bytes_in_buffer has reached zero and more

+        data is wanted.  In typical applications, it should read fresh data

+        into the buffer (ignoring the current state of next_input_byte and

+        bytes_in_buffer), reset the pointer & count to the start of the

+        buffer, and return TRUE indicating that the buffer has been reloaded.

+        It is not necessary to fill the buffer entirely, only to obtain at

+        least one more byte.  bytes_in_buffer MUST be set to a positive value

+        if TRUE is returned.  A FALSE return should only be used when I/O

+        suspension is desired (this mode is discussed in the next section).

+

+skip_input_data (j_decompress_ptr cinfo, long num_bytes)

+        Skip num_bytes worth of data.  The buffer pointer and count should

+        be advanced over num_bytes input bytes, refilling the buffer as

+        needed.  This is used to skip over a potentially large amount of

+        uninteresting data (such as an APPn marker).  In some applications

+        it may be possible to optimize away the reading of the skipped data,

+        but it's not clear that being smart is worth much trouble; large

+        skips are uncommon.  bytes_in_buffer may be zero on return.

+        A zero or negative skip count should be treated as a no-op.

+

+resync_to_restart (j_decompress_ptr cinfo, int desired)

+        This routine is called only when the decompressor has failed to find

+        a restart (RSTn) marker where one is expected.  Its mission is to

+        find a suitable point for resuming decompression.  For most

+        applications, we recommend that you just use the default resync

+        procedure, jpeg_resync_to_restart().  However, if you are able to back

+        up in the input data stream, or if you have a-priori knowledge about

+        the likely location of restart markers, you may be able to do better.

+        Read the read_restart_marker() and jpeg_resync_to_restart() routines

+        in jdmarker.c if you think you'd like to implement your own resync

+        procedure.

+

+term_source (j_decompress_ptr cinfo)

+        Terminate source --- called by jpeg_finish_decompress() after all

+        data has been read.  Often a no-op.

+

+For both fill_input_buffer() and skip_input_data(), there is no such thing

+as an EOF return.  If the end of the file has been reached, the routine has

+a choice of exiting via ERREXIT() or inserting fake data into the buffer.

+In most cases, generating a warning message and inserting a fake EOI marker

+is the best course of action --- this will allow the decompressor to output

+however much of the image is there.  In pathological cases, the decompressor

+may swallow the EOI and again demand data ... just keep feeding it fake EOIs.

+jdatasrc.c illustrates the recommended error recovery behavior.

+

+term_source() is NOT called by jpeg_abort() or jpeg_destroy().  If you want

+the source manager to be cleaned up during an abort, you must do it yourself.

+

+You will also need code to create a jpeg_source_mgr struct, fill in its method

+pointers, and insert a pointer to the struct into the "src" field of the JPEG

+decompression object.  This can be done in-line in your setup code if you

+like, but it's probably cleaner to provide a separate routine similar to the

+jpeg_stdio_src() or jpeg_mem_src() routines of the supplied source managers.

+

+For more information, consult the memory and stdio source and destination

+managers in jdatasrc.c and jdatadst.c.

+

+

+I/O suspension

+--------------

+

+Some applications need to use the JPEG library as an incremental memory-to-

+memory filter: when the compressed data buffer is filled or emptied, they want

+control to return to the outer loop, rather than expecting that the buffer can

+be emptied or reloaded within the data source/destination manager subroutine.

+The library supports this need by providing an "I/O suspension" mode, which we

+describe in this section.

+

+The I/O suspension mode is not a panacea: nothing is guaranteed about the

+maximum amount of time spent in any one call to the library, so it will not

+eliminate response-time problems in single-threaded applications.  If you

+need guaranteed response time, we suggest you "bite the bullet" and implement

+a real multi-tasking capability.

+

+To use I/O suspension, cooperation is needed between the calling application

+and the data source or destination manager; you will always need a custom

+source/destination manager.  (Please read the previous section if you haven't

+already.)  The basic idea is that the empty_output_buffer() or

+fill_input_buffer() routine is a no-op, merely returning FALSE to indicate

+that it has done nothing.  Upon seeing this, the JPEG library suspends

+operation and returns to its caller.  The surrounding application is

+responsible for emptying or refilling the work buffer before calling the

+JPEG library again.

+

+Compression suspension:

+

+For compression suspension, use an empty_output_buffer() routine that returns

+FALSE; typically it will not do anything else.  This will cause the

+compressor to return to the caller of jpeg_write_scanlines(), with the return

+value indicating that not all the supplied scanlines have been accepted.

+The application must make more room in the output buffer, adjust the output

+buffer pointer/count appropriately, and then call jpeg_write_scanlines()

+again, pointing to the first unconsumed scanline.

+

+When forced to suspend, the compressor will backtrack to a convenient stopping

+point (usually the start of the current MCU); it will regenerate some output

+data when restarted.  Therefore, although empty_output_buffer() is only

+called when the buffer is filled, you should NOT write out the entire buffer

+after a suspension.  Write only the data up to the current position of

+next_output_byte/free_in_buffer.  The data beyond that point will be

+regenerated after resumption.

+

+Because of the backtracking behavior, a good-size output buffer is essential

+for efficiency; you don't want the compressor to suspend often.  (In fact, an

+overly small buffer could lead to infinite looping, if a single MCU required

+more data than would fit in the buffer.)  We recommend a buffer of at least

+several Kbytes.  You may want to insert explicit code to ensure that you don't

+call jpeg_write_scanlines() unless there is a reasonable amount of space in

+the output buffer; in other words, flush the buffer before trying to compress

+more data.

+

+The compressor does not allow suspension while it is trying to write JPEG

+markers at the beginning and end of the file.  This means that:

+  * At the beginning of a compression operation, there must be enough free

+    space in the output buffer to hold the header markers (typically 600 or

+    so bytes).  The recommended buffer size is bigger than this anyway, so

+    this is not a problem as long as you start with an empty buffer.  However,

+    this restriction might catch you if you insert large special markers, such

+    as a JFIF thumbnail image, without flushing the buffer afterwards.

+  * When you call jpeg_finish_compress(), there must be enough space in the

+    output buffer to emit any buffered data and the final EOI marker.  In the

+    current implementation, half a dozen bytes should suffice for this, but

+    for safety's sake we recommend ensuring that at least 100 bytes are free

+    before calling jpeg_finish_compress().

+

+A more significant restriction is that jpeg_finish_compress() cannot suspend.

+This means you cannot use suspension with multi-pass operating modes, namely

+Huffman code optimization and multiple-scan output.  Those modes write the

+whole file during jpeg_finish_compress(), which will certainly result in

+buffer overrun.  (Note that this restriction applies only to compression,

+not decompression.  The decompressor supports input suspension in all of its

+operating modes.)

+

+Decompression suspension:

+

+For decompression suspension, use a fill_input_buffer() routine that simply

+returns FALSE (except perhaps during error recovery, as discussed below).

+This will cause the decompressor to return to its caller with an indication

+that suspension has occurred.  This can happen at four places:

+  * jpeg_read_header(): will return JPEG_SUSPENDED.

+  * jpeg_start_decompress(): will return FALSE, rather than its usual TRUE.

+  * jpeg_read_scanlines(): will return the number of scanlines already

+        completed (possibly 0).

+  * jpeg_finish_decompress(): will return FALSE, rather than its usual TRUE.

+The surrounding application must recognize these cases, load more data into

+the input buffer, and repeat the call.  In the case of jpeg_read_scanlines(),

+increment the passed pointers past any scanlines successfully read.

+

+Just as with compression, the decompressor will typically backtrack to a

+convenient restart point before suspending.  When fill_input_buffer() is

+called, next_input_byte/bytes_in_buffer point to the current restart point,

+which is where the decompressor will backtrack to if FALSE is returned.

+The data beyond that position must NOT be discarded if you suspend; it needs

+to be re-read upon resumption.  In most implementations, you'll need to shift

+this data down to the start of your work buffer and then load more data after

+it.  Again, this behavior means that a several-Kbyte work buffer is essential

+for decent performance; furthermore, you should load a reasonable amount of

+new data before resuming decompression.  (If you loaded, say, only one new

+byte each time around, you could waste a LOT of cycles.)

+

+The skip_input_data() source manager routine requires special care in a

+suspension scenario.  This routine is NOT granted the ability to suspend the

+decompressor; it can decrement bytes_in_buffer to zero, but no more.  If the

+requested skip distance exceeds the amount of data currently in the input

+buffer, then skip_input_data() must set bytes_in_buffer to zero and record the

+additional skip distance somewhere else.  The decompressor will immediately

+call fill_input_buffer(), which should return FALSE, which will cause a

+suspension return.  The surrounding application must then arrange to discard

+the recorded number of bytes before it resumes loading the input buffer.

+(Yes, this design is rather baroque, but it avoids complexity in the far more

+common case where a non-suspending source manager is used.)

+

+If the input data has been exhausted, we recommend that you emit a warning

+and insert dummy EOI markers just as a non-suspending data source manager

+would do.  This can be handled either in the surrounding application logic or

+within fill_input_buffer(); the latter is probably more efficient.  If

+fill_input_buffer() knows that no more data is available, it can set the

+pointer/count to point to a dummy EOI marker and then return TRUE just as

+though it had read more data in a non-suspending situation.

+

+The decompressor does not attempt to suspend within standard JPEG markers;

+instead it will backtrack to the start of the marker and reprocess the whole

+marker next time.  Hence the input buffer must be large enough to hold the

+longest standard marker in the file.  Standard JPEG markers should normally

+not exceed a few hundred bytes each (DHT tables are typically the longest).

+We recommend at least a 2K buffer for performance reasons, which is much

+larger than any correct marker is likely to be.  For robustness against

+damaged marker length counts, you may wish to insert a test in your

+application for the case that the input buffer is completely full and yet

+the decoder has suspended without consuming any data --- otherwise, if this

+situation did occur, it would lead to an endless loop.  (The library can't

+provide this test since it has no idea whether "the buffer is full", or

+even whether there is a fixed-size input buffer.)

+

+The input buffer would need to be 64K to allow for arbitrary COM or APPn

+markers, but these are handled specially: they are either saved into allocated

+memory, or skipped over by calling skip_input_data().  In the former case,

+suspension is handled correctly, and in the latter case, the problem of

+buffer overrun is placed on skip_input_data's shoulders, as explained above.

+Note that if you provide your own marker handling routine for large markers,

+you should consider how to deal with buffer overflow.

+

+Multiple-buffer management:

+

+In some applications it is desirable to store the compressed data in a linked

+list of buffer areas, so as to avoid data copying.  This can be handled by

+having empty_output_buffer() or fill_input_buffer() set the pointer and count

+to reference the next available buffer; FALSE is returned only if no more

+buffers are available.  Although seemingly straightforward, there is a

+pitfall in this approach: the backtrack that occurs when FALSE is returned

+could back up into an earlier buffer.  For example, when fill_input_buffer()

+is called, the current pointer & count indicate the backtrack restart point.

+Since fill_input_buffer() will set the pointer and count to refer to a new

+buffer, the restart position must be saved somewhere else.  Suppose a second

+call to fill_input_buffer() occurs in the same library call, and no

+additional input data is available, so fill_input_buffer must return FALSE.

+If the JPEG library has not moved the pointer/count forward in the current

+buffer, then *the correct restart point is the saved position in the prior

+buffer*.  Prior buffers may be discarded only after the library establishes

+a restart point within a later buffer.  Similar remarks apply for output into

+a chain of buffers.

+

+The library will never attempt to backtrack over a skip_input_data() call,

+so any skipped data can be permanently discarded.  You still have to deal

+with the case of skipping not-yet-received data, however.

+

+It's much simpler to use only a single buffer; when fill_input_buffer() is

+called, move any unconsumed data (beyond the current pointer/count) down to

+the beginning of this buffer and then load new data into the remaining buffer

+space.  This approach requires a little more data copying but is far easier

+to get right.

+

+

+Progressive JPEG support

+------------------------

+

+Progressive JPEG rearranges the stored data into a series of scans of

+increasing quality.  In situations where a JPEG file is transmitted across a

+slow communications link, a decoder can generate a low-quality image very

+quickly from the first scan, then gradually improve the displayed quality as

+more scans are received.  The final image after all scans are complete is

+identical to that of a regular (sequential) JPEG file of the same quality

+setting.  Progressive JPEG files are often slightly smaller than equivalent

+sequential JPEG files, but the possibility of incremental display is the main

+reason for using progressive JPEG.

+

+The IJG encoder library generates progressive JPEG files when given a

+suitable "scan script" defining how to divide the data into scans.

+Creation of progressive JPEG files is otherwise transparent to the encoder.

+Progressive JPEG files can also be read transparently by the decoder library.

+If the decoding application simply uses the library as defined above, it

+will receive a final decoded image without any indication that the file was

+progressive.  Of course, this approach does not allow incremental display.

+To perform incremental display, an application needs to use the decoder

+library's "buffered-image" mode, in which it receives a decoded image

+multiple times.

+

+Each displayed scan requires about as much work to decode as a full JPEG

+image of the same size, so the decoder must be fairly fast in relation to the

+data transmission rate in order to make incremental display useful.  However,

+it is possible to skip displaying the image and simply add the incoming bits

+to the decoder's coefficient buffer.  This is fast because only Huffman

+decoding need be done, not IDCT, upsampling, colorspace conversion, etc.

+The IJG decoder library allows the application to switch dynamically between

+displaying the image and simply absorbing the incoming bits.  A properly

+coded application can automatically adapt the number of display passes to

+suit the time available as the image is received.  Also, a final

+higher-quality display cycle can be performed from the buffered data after

+the end of the file is reached.

+

+Progressive compression:

+

+To create a progressive JPEG file (or a multiple-scan sequential JPEG file),

+set the scan_info cinfo field to point to an array of scan descriptors, and

+perform compression as usual.  Instead of constructing your own scan list,

+you can call the jpeg_simple_progression() helper routine to create a

+recommended progression sequence; this method should be used by all

+applications that don't want to get involved in the nitty-gritty of

+progressive scan sequence design.  (If you want to provide user control of

+scan sequences, you may wish to borrow the scan script reading code found

+in rdswitch.c, so that you can read scan script files just like cjpeg's.)

+When scan_info is not NULL, the compression library will store DCT'd data

+into a buffer array as jpeg_write_scanlines() is called, and will emit all

+the requested scans during jpeg_finish_compress().  This implies that

+multiple-scan output cannot be created with a suspending data destination

+manager, since jpeg_finish_compress() does not support suspension.  We

+should also note that the compressor currently forces Huffman optimization

+mode when creating a progressive JPEG file, because the default Huffman

+tables are unsuitable for progressive files.

+

+Progressive decompression:

+

+When buffered-image mode is not used, the decoder library will read all of

+a multi-scan file during jpeg_start_decompress(), so that it can provide a

+final decoded image.  (Here "multi-scan" means either progressive or

+multi-scan sequential.)  This makes multi-scan files transparent to the

+decoding application.  However, existing applications that used suspending

+input with version 5 of the IJG library will need to be modified to check

+for a suspension return from jpeg_start_decompress().

+

+To perform incremental display, an application must use the library's

+buffered-image mode.  This is described in the next section.

+

+

+Buffered-image mode

+-------------------

+

+In buffered-image mode, the library stores the partially decoded image in a

+coefficient buffer, from which it can be read out as many times as desired.

+This mode is typically used for incremental display of progressive JPEG files,

+but it can be used with any JPEG file.  Each scan of a progressive JPEG file

+adds more data (more detail) to the buffered image.  The application can

+display in lockstep with the source file (one display pass per input scan),

+or it can allow input processing to outrun display processing.  By making

+input and display processing run independently, it is possible for the

+application to adapt progressive display to a wide range of data transmission

+rates.

+

+The basic control flow for buffered-image decoding is

+

+        jpeg_create_decompress()

+        set data source

+        jpeg_read_header()

+        set overall decompression parameters

+        cinfo.buffered_image = TRUE;    /* select buffered-image mode */

+        jpeg_start_decompress()

+        for (each output pass) {

+            adjust output decompression parameters if required

+            jpeg_start_output()         /* start a new output pass */

+            for (all scanlines in image) {

+                jpeg_read_scanlines()

+                display scanlines

+            }

+            jpeg_finish_output()        /* terminate output pass */

+        }

+        jpeg_finish_decompress()

+        jpeg_destroy_decompress()

+

+This differs from ordinary unbuffered decoding in that there is an additional

+level of looping.  The application can choose how many output passes to make

+and how to display each pass.

+

+The simplest approach to displaying progressive images is to do one display

+pass for each scan appearing in the input file.  In this case the outer loop

+condition is typically

+        while (! jpeg_input_complete(&cinfo))

+and the start-output call should read

+        jpeg_start_output(&cinfo, cinfo.input_scan_number);

+The second parameter to jpeg_start_output() indicates which scan of the input

+file is to be displayed; the scans are numbered starting at 1 for this

+purpose.  (You can use a loop counter starting at 1 if you like, but using

+the library's input scan counter is easier.)  The library automatically reads

+data as necessary to complete each requested scan, and jpeg_finish_output()

+advances to the next scan or end-of-image marker (hence input_scan_number

+will be incremented by the time control arrives back at jpeg_start_output()).

+With this technique, data is read from the input file only as needed, and

+input and output processing run in lockstep.

+

+After reading the final scan and reaching the end of the input file, the

+buffered image remains available; it can be read additional times by

+repeating the jpeg_start_output()/jpeg_read_scanlines()/jpeg_finish_output()

+sequence.  For example, a useful technique is to use fast one-pass color

+quantization for display passes made while the image is arriving, followed by

+a final display pass using two-pass quantization for highest quality.  This

+is done by changing the library parameters before the final output pass.

+Changing parameters between passes is discussed in detail below.

+

+In general the last scan of a progressive file cannot be recognized as such

+until after it is read, so a post-input display pass is the best approach if

+you want special processing in the final pass.

+

+When done with the image, be sure to call jpeg_finish_decompress() to release

+the buffered image (or just use jpeg_destroy_decompress()).

+

+If input data arrives faster than it can be displayed, the application can

+cause the library to decode input data in advance of what's needed to produce

+output.  This is done by calling the routine jpeg_consume_input().

+The return value is one of the following:

+        JPEG_REACHED_SOS:    reached an SOS marker (the start of a new scan)

+        JPEG_REACHED_EOI:    reached the EOI marker (end of image)

+        JPEG_ROW_COMPLETED:  completed reading one MCU row of compressed data

+        JPEG_SCAN_COMPLETED: completed reading last MCU row of current scan

+        JPEG_SUSPENDED:      suspended before completing any of the above

+(JPEG_SUSPENDED can occur only if a suspending data source is used.)  This

+routine can be called at any time after initializing the JPEG object.  It

+reads some additional data and returns when one of the indicated significant

+events occurs.  (If called after the EOI marker is reached, it will

+immediately return JPEG_REACHED_EOI without attempting to read more data.)

+

+The library's output processing will automatically call jpeg_consume_input()

+whenever the output processing overtakes the input; thus, simple lockstep

+display requires no direct calls to jpeg_consume_input().  But by adding

+calls to jpeg_consume_input(), you can absorb data in advance of what is

+being displayed.  This has two benefits:

+  * You can limit buildup of unprocessed data in your input buffer.

+  * You can eliminate extra display passes by paying attention to the

+    state of the library's input processing.

+

+The first of these benefits only requires interspersing calls to

+jpeg_consume_input() with your display operations and any other processing

+you may be doing.  To avoid wasting cycles due to backtracking, it's best to

+call jpeg_consume_input() only after a hundred or so new bytes have arrived.

+This is discussed further under "I/O suspension", above.  (Note: the JPEG

+library currently is not thread-safe.  You must not call jpeg_consume_input()

+from one thread of control if a different library routine is working on the

+same JPEG object in another thread.)

+

+When input arrives fast enough that more than one new scan is available

+before you start a new output pass, you may as well skip the output pass

+corresponding to the completed scan.  This occurs for free if you pass

+cinfo.input_scan_number as the target scan number to jpeg_start_output().

+The input_scan_number field is simply the index of the scan currently being

+consumed by the input processor.  You can ensure that this is up-to-date by

+emptying the input buffer just before calling jpeg_start_output(): call

+jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or

+JPEG_REACHED_EOI.

+

+The target scan number passed to jpeg_start_output() is saved in the

+cinfo.output_scan_number field.  The library's output processing calls

+jpeg_consume_input() whenever the current input scan number and row within

+that scan is less than or equal to the current output scan number and row.

+Thus, input processing can "get ahead" of the output processing but is not

+allowed to "fall behind".  You can achieve several different effects by

+manipulating this interlock rule.  For example, if you pass a target scan

+number greater than the current input scan number, the output processor will

+wait until that scan starts to arrive before producing any output.  (To avoid

+an infinite loop, the target scan number is automatically reset to the last

+scan number when the end of image is reached.  Thus, if you specify a large

+target scan number, the library will just absorb the entire input file and

+then perform an output pass.  This is effectively the same as what

+jpeg_start_decompress() does when you don't select buffered-image mode.)

+When you pass a target scan number equal to the current input scan number,

+the image is displayed no faster than the current input scan arrives.  The

+final possibility is to pass a target scan number less than the current input

+scan number; this disables the input/output interlock and causes the output

+processor to simply display whatever it finds in the image buffer, without

+waiting for input.  (However, the library will not accept a target scan

+number less than one, so you can't avoid waiting for the first scan.)

+

+When data is arriving faster than the output display processing can advance

+through the image, jpeg_consume_input() will store data into the buffered

+image beyond the point at which the output processing is reading data out

+again.  If the input arrives fast enough, it may "wrap around" the buffer to

+the point where the input is more than one whole scan ahead of the output.

+If the output processing simply proceeds through its display pass without

+paying attention to the input, the effect seen on-screen is that the lower

+part of the image is one or more scans better in quality than the upper part.

+Then, when the next output scan is started, you have a choice of what target

+scan number to use.  The recommended choice is to use the current input scan

+number at that time, which implies that you've skipped the output scans

+corresponding to the input scans that were completed while you processed the

+previous output scan.  In this way, the decoder automatically adapts its

+speed to the arriving data, by skipping output scans as necessary to keep up

+with the arriving data.

+

+When using this strategy, you'll want to be sure that you perform a final

+output pass after receiving all the data; otherwise your last display may not

+be full quality across the whole screen.  So the right outer loop logic is

+something like this:

+        do {

+            absorb any waiting input by calling jpeg_consume_input()

+            final_pass = jpeg_input_complete(&cinfo);

+            adjust output decompression parameters if required

+            jpeg_start_output(&cinfo, cinfo.input_scan_number);

+            ...

+            jpeg_finish_output()

+        } while (! final_pass);

+rather than quitting as soon as jpeg_input_complete() returns TRUE.  This

+arrangement makes it simple to use higher-quality decoding parameters

+for the final pass.  But if you don't want to use special parameters for

+the final pass, the right loop logic is like this:

+        for (;;) {

+            absorb any waiting input by calling jpeg_consume_input()

+            jpeg_start_output(&cinfo, cinfo.input_scan_number);

+            ...

+            jpeg_finish_output()

+            if (jpeg_input_complete(&cinfo) &&

+                cinfo.input_scan_number == cinfo.output_scan_number)

+              break;

+        }

+In this case you don't need to know in advance whether an output pass is to

+be the last one, so it's not necessary to have reached EOF before starting

+the final output pass; rather, what you want to test is whether the output

+pass was performed in sync with the final input scan.  This form of the loop

+will avoid an extra output pass whenever the decoder is able (or nearly able)

+to keep up with the incoming data.

+

+When the data transmission speed is high, you might begin a display pass,

+then find that much or all of the file has arrived before you can complete

+the pass.  (You can detect this by noting the JPEG_REACHED_EOI return code

+from jpeg_consume_input(), or equivalently by testing jpeg_input_complete().)

+In this situation you may wish to abort the current display pass and start a

+new one using the newly arrived information.  To do so, just call

+jpeg_finish_output() and then start a new pass with jpeg_start_output().

+

+A variant strategy is to abort and restart display if more than one complete

+scan arrives during an output pass; this can be detected by noting

+JPEG_REACHED_SOS returns and/or examining cinfo.input_scan_number.  This

+idea should be employed with caution, however, since the display process

+might never get to the bottom of the image before being aborted, resulting

+in the lower part of the screen being several passes worse than the upper.

+In most cases it's probably best to abort an output pass only if the whole

+file has arrived and you want to begin the final output pass immediately.

+

+When receiving data across a communication link, we recommend always using

+the current input scan number for the output target scan number; if a

+higher-quality final pass is to be done, it should be started (aborting any

+incomplete output pass) as soon as the end of file is received.  However,

+many other strategies are possible.  For example, the application can examine

+the parameters of the current input scan and decide whether to display it or

+not.  If the scan contains only chroma data, one might choose not to use it

+as the target scan, expecting that the scan will be small and will arrive

+quickly.  To skip to the next scan, call jpeg_consume_input() until it

+returns JPEG_REACHED_SOS or JPEG_REACHED_EOI.  Or just use the next higher

+number as the target scan for jpeg_start_output(); but that method doesn't

+let you inspect the next scan's parameters before deciding to display it.

+

+

+In buffered-image mode, jpeg_start_decompress() never performs input and

+thus never suspends.  An application that uses input suspension with

+buffered-image mode must be prepared for suspension returns from these

+routines:

+* jpeg_start_output() performs input only if you request 2-pass quantization

+  and the target scan isn't fully read yet.  (This is discussed below.)

+* jpeg_read_scanlines(), as always, returns the number of scanlines that it

+  was able to produce before suspending.

+* jpeg_finish_output() will read any markers following the target scan,

+  up to the end of the file or the SOS marker that begins another scan.

+  (But it reads no input if jpeg_consume_input() has already reached the

+  end of the file or a SOS marker beyond the target output scan.)

+* jpeg_finish_decompress() will read until the end of file, and thus can

+  suspend if the end hasn't already been reached (as can be tested by

+  calling jpeg_input_complete()).

+jpeg_start_output(), jpeg_finish_output(), and jpeg_finish_decompress()

+all return TRUE if they completed their tasks, FALSE if they had to suspend.

+In the event of a FALSE return, the application must load more input data

+and repeat the call.  Applications that use non-suspending data sources need

+not check the return values of these three routines.

+

+

+It is possible to change decoding parameters between output passes in the

+buffered-image mode.  The decoder library currently supports only very

+limited changes of parameters.  ONLY THE FOLLOWING parameter changes are

+allowed after jpeg_start_decompress() is called:

+* dct_method can be changed before each call to jpeg_start_output().

+  For example, one could use a fast DCT method for early scans, changing

+  to a higher quality method for the final scan.

+* dither_mode can be changed before each call to jpeg_start_output();

+  of course this has no impact if not using color quantization.  Typically

+  one would use ordered dither for initial passes, then switch to

+  Floyd-Steinberg dither for the final pass.  Caution: changing dither mode

+  can cause more memory to be allocated by the library.  Although the amount

+  of memory involved is not large (a scanline or so), it may cause the

+  initial max_memory_to_use specification to be exceeded, which in the worst

+  case would result in an out-of-memory failure.

+* do_block_smoothing can be changed before each call to jpeg_start_output().

+  This setting is relevant only when decoding a progressive JPEG image.

+  During the first DC-only scan, block smoothing provides a very "fuzzy" look

+  instead of the very "blocky" look seen without it; which is better seems a

+  matter of personal taste.  But block smoothing is nearly always a win

+  during later stages, especially when decoding a successive-approximation

+  image: smoothing helps to hide the slight blockiness that otherwise shows

+  up on smooth gradients until the lowest coefficient bits are sent.

+* Color quantization mode can be changed under the rules described below.

+  You *cannot* change between full-color and quantized output (because that

+  would alter the required I/O buffer sizes), but you can change which

+  quantization method is used.

+

+When generating color-quantized output, changing quantization method is a

+very useful way of switching between high-speed and high-quality display.

+The library allows you to change among its three quantization methods:

+1. Single-pass quantization to a fixed color cube.

+   Selected by cinfo.two_pass_quantize = FALSE and cinfo.colormap = NULL.

+2. Single-pass quantization to an application-supplied colormap.

+   Selected by setting cinfo.colormap to point to the colormap (the value of

+   two_pass_quantize is ignored); also set cinfo.actual_number_of_colors.

+3. Two-pass quantization to a colormap chosen specifically for the image.

+   Selected by cinfo.two_pass_quantize = TRUE and cinfo.colormap = NULL.

+   (This is the default setting selected by jpeg_read_header, but it is

+   probably NOT what you want for the first pass of progressive display!)

+These methods offer successively better quality and lesser speed.  However,

+only the first method is available for quantizing in non-RGB color spaces.

+

+IMPORTANT: because the different quantizer methods have very different

+working-storage requirements, the library requires you to indicate which

+one(s) you intend to use before you call jpeg_start_decompress().  (If we did

+not require this, the max_memory_to_use setting would be a complete fiction.)

+You do this by setting one or more of these three cinfo fields to TRUE:

+        enable_1pass_quant              Fixed color cube colormap

+        enable_external_quant           Externally-supplied colormap

+        enable_2pass_quant              Two-pass custom colormap

+All three are initialized FALSE by jpeg_read_header().  But

+jpeg_start_decompress() automatically sets TRUE the one selected by the

+current two_pass_quantize and colormap settings, so you only need to set the

+enable flags for any other quantization methods you plan to change to later.

+

+After setting the enable flags correctly at jpeg_start_decompress() time, you

+can change to any enabled quantization method by setting two_pass_quantize

+and colormap properly just before calling jpeg_start_output().  The following

+special rules apply:

+1. You must explicitly set cinfo.colormap to NULL when switching to 1-pass

+   or 2-pass mode from a different mode, or when you want the 2-pass

+   quantizer to be re-run to generate a new colormap.

+2. To switch to an external colormap, or to change to a different external

+   colormap than was used on the prior pass, you must call

+   jpeg_new_colormap() after setting cinfo.colormap.

+NOTE: if you want to use the same colormap as was used in the prior pass,

+you should not do either of these things.  This will save some nontrivial

+switchover costs.

+(These requirements exist because cinfo.colormap will always be non-NULL

+after completing a prior output pass, since both the 1-pass and 2-pass

+quantizers set it to point to their output colormaps.  Thus you have to

+do one of these two things to notify the library that something has changed.

+Yup, it's a bit klugy, but it's necessary to do it this way for backwards

+compatibility.)

+

+Note that in buffered-image mode, the library generates any requested colormap

+during jpeg_start_output(), not during jpeg_start_decompress().

+

+When using two-pass quantization, jpeg_start_output() makes a pass over the

+buffered image to determine the optimum color map; it therefore may take a

+significant amount of time, whereas ordinarily it does little work.  The

+progress monitor hook is called during this pass, if defined.  It is also

+important to realize that if the specified target scan number is greater than

+or equal to the current input scan number, jpeg_start_output() will attempt

+to consume input as it makes this pass.  If you use a suspending data source,

+you need to check for a FALSE return from jpeg_start_output() under these

+conditions.  The combination of 2-pass quantization and a not-yet-fully-read

+target scan is the only case in which jpeg_start_output() will consume input.

+

+

+Application authors who support buffered-image mode may be tempted to use it

+for all JPEG images, even single-scan ones.  This will work, but it is

+inefficient: there is no need to create an image-sized coefficient buffer for

+single-scan images.  Requesting buffered-image mode for such an image wastes

+memory.  Worse, it can cost time on large images, since the buffered data has

+to be swapped out or written to a temporary file.  If you are concerned about

+maximum performance on baseline JPEG files, you should use buffered-image

+mode only when the incoming file actually has multiple scans.  This can be

+tested by calling jpeg_has_multiple_scans(), which will return a correct

+result at any time after jpeg_read_header() completes.

+

+It is also worth noting that when you use jpeg_consume_input() to let input

+processing get ahead of output processing, the resulting pattern of access to

+the coefficient buffer is quite nonsequential.  It's best to use the memory

+manager jmemnobs.c if you can (ie, if you have enough real or virtual main

+memory).  If not, at least make sure that max_memory_to_use is set as high as

+possible.  If the JPEG memory manager has to use a temporary file, you will

+probably see a lot of disk traffic and poor performance.  (This could be

+improved with additional work on the memory manager, but we haven't gotten

+around to it yet.)

+

+In some applications it may be convenient to use jpeg_consume_input() for all

+input processing, including reading the initial markers; that is, you may

+wish to call jpeg_consume_input() instead of jpeg_read_header() during

+startup.  This works, but note that you must check for JPEG_REACHED_SOS and

+JPEG_REACHED_EOI return codes as the equivalent of jpeg_read_header's codes.

+Once the first SOS marker has been reached, you must call

+jpeg_start_decompress() before jpeg_consume_input() will consume more input;

+it'll just keep returning JPEG_REACHED_SOS until you do.  If you read a

+tables-only file this way, jpeg_consume_input() will return JPEG_REACHED_EOI

+without ever returning JPEG_REACHED_SOS; be sure to check for this case.

+If this happens, the decompressor will not read any more input until you call

+jpeg_abort() to reset it.  It is OK to call jpeg_consume_input() even when not

+using buffered-image mode, but in that case it's basically a no-op after the

+initial markers have been read: it will just return JPEG_SUSPENDED.

+

+

+Abbreviated datastreams and multiple images

+-------------------------------------------

+

+A JPEG compression or decompression object can be reused to process multiple

+images.  This saves a small amount of time per image by eliminating the

+"create" and "destroy" operations, but that isn't the real purpose of the

+feature.  Rather, reuse of an object provides support for abbreviated JPEG

+datastreams.  Object reuse can also simplify processing a series of images in

+a single input or output file.  This section explains these features.

+

+A JPEG file normally contains several hundred bytes worth of quantization

+and Huffman tables.  In a situation where many images will be stored or

+transmitted with identical tables, this may represent an annoying overhead.

+The JPEG standard therefore permits tables to be omitted.  The standard

+defines three classes of JPEG datastreams:

+  * "Interchange" datastreams contain an image and all tables needed to decode

+     the image.  These are the usual kind of JPEG file.

+  * "Abbreviated image" datastreams contain an image, but are missing some or

+    all of the tables needed to decode that image.

+  * "Abbreviated table specification" (henceforth "tables-only") datastreams

+    contain only table specifications.

+To decode an abbreviated image, it is necessary to load the missing table(s)

+into the decoder beforehand.  This can be accomplished by reading a separate

+tables-only file.  A variant scheme uses a series of images in which the first

+image is an interchange (complete) datastream, while subsequent ones are

+abbreviated and rely on the tables loaded by the first image.  It is assumed

+that once the decoder has read a table, it will remember that table until a

+new definition for the same table number is encountered.

+

+It is the application designer's responsibility to figure out how to associate

+the correct tables with an abbreviated image.  While abbreviated datastreams

+can be useful in a closed environment, their use is strongly discouraged in

+any situation where data exchange with other applications might be needed.

+Caveat designer.

+

+The JPEG library provides support for reading and writing any combination of

+tables-only datastreams and abbreviated images.  In both compression and

+decompression objects, a quantization or Huffman table will be retained for

+the lifetime of the object, unless it is overwritten by a new table definition.

+

+

+To create abbreviated image datastreams, it is only necessary to tell the

+compressor not to emit some or all of the tables it is using.  Each

+quantization and Huffman table struct contains a boolean field "sent_table",

+which normally is initialized to FALSE.  For each table used by the image, the

+header-writing process emits the table and sets sent_table = TRUE unless it is

+already TRUE.  (In normal usage, this prevents outputting the same table

+definition multiple times, as would otherwise occur because the chroma

+components typically share tables.)  Thus, setting this field to TRUE before

+calling jpeg_start_compress() will prevent the table from being written at

+all.

+

+If you want to create a "pure" abbreviated image file containing no tables,

+just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the

+tables.  If you want to emit some but not all tables, you'll need to set the

+individual sent_table fields directly.

+

+To create an abbreviated image, you must also call jpeg_start_compress()

+with a second parameter of FALSE, not TRUE.  Otherwise jpeg_start_compress()

+will force all the sent_table fields to FALSE.  (This is a safety feature to

+prevent abbreviated images from being created accidentally.)

+

+To create a tables-only file, perform the same parameter setup that you

+normally would, but instead of calling jpeg_start_compress() and so on, call

+jpeg_write_tables(&cinfo).  This will write an abbreviated datastream

+containing only SOI, DQT and/or DHT markers, and EOI.  All the quantization

+and Huffman tables that are currently defined in the compression object will

+be emitted unless their sent_tables flag is already TRUE, and then all the

+sent_tables flags will be set TRUE.

+

+A sure-fire way to create matching tables-only and abbreviated image files

+is to proceed as follows:

+

+        create JPEG compression object

+        set JPEG parameters

+        set destination to tables-only file

+        jpeg_write_tables(&cinfo);

+        set destination to image file

+        jpeg_start_compress(&cinfo, FALSE);

+        write data...

+        jpeg_finish_compress(&cinfo);

+

+Since the JPEG parameters are not altered between writing the table file and

+the abbreviated image file, the same tables are sure to be used.  Of course,

+you can repeat the jpeg_start_compress() ... jpeg_finish_compress() sequence

+many times to produce many abbreviated image files matching the table file.

+

+You cannot suppress output of the computed Huffman tables when Huffman

+optimization is selected.  (If you could, there'd be no way to decode the

+image...)  Generally, you don't want to set optimize_coding = TRUE when

+you are trying to produce abbreviated files.

+

+In some cases you might want to compress an image using tables which are

+not stored in the application, but are defined in an interchange or

+tables-only file readable by the application.  This can be done by setting up

+a JPEG decompression object to read the specification file, then copying the

+tables into your compression object.  See jpeg_copy_critical_parameters()

+for an example of copying quantization tables.

+

+

+To read abbreviated image files, you simply need to load the proper tables

+into the decompression object before trying to read the abbreviated image.

+If the proper tables are stored in the application program, you can just

+allocate the table structs and fill in their contents directly.  For example,

+to load a fixed quantization table into table slot "n":

+

+    if (cinfo.quant_tbl_ptrs[n] == NULL)

+      cinfo.quant_tbl_ptrs[n] = jpeg_alloc_quant_table((j_common_ptr) &cinfo);

+    quant_ptr = cinfo.quant_tbl_ptrs[n];        /* quant_ptr is JQUANT_TBL* */

+    for (i = 0; i < 64; i++) {

+      /* Qtable[] is desired quantization table, in natural array order */

+      quant_ptr->quantval[i] = Qtable[i];

+    }

+

+Code to load a fixed Huffman table is typically (for AC table "n"):

+

+    if (cinfo.ac_huff_tbl_ptrs[n] == NULL)

+      cinfo.ac_huff_tbl_ptrs[n] = jpeg_alloc_huff_table((j_common_ptr) &cinfo);

+    huff_ptr = cinfo.ac_huff_tbl_ptrs[n];       /* huff_ptr is JHUFF_TBL* */

+    for (i = 1; i <= 16; i++) {

+      /* counts[i] is number of Huffman codes of length i bits, i=1..16 */

+      huff_ptr->bits[i] = counts[i];

+    }

+    for (i = 0; i < 256; i++) {

+      /* symbols[] is the list of Huffman symbols, in code-length order */

+      huff_ptr->huffval[i] = symbols[i];

+    }

+

+(Note that trying to set cinfo.quant_tbl_ptrs[n] to point directly at a

+constant JQUANT_TBL object is not safe.  If the incoming file happened to

+contain a quantization table definition, your master table would get

+overwritten!  Instead allocate a working table copy and copy the master table

+into it, as illustrated above.  Ditto for Huffman tables, of course.)

+

+You might want to read the tables from a tables-only file, rather than

+hard-wiring them into your application.  The jpeg_read_header() call is

+sufficient to read a tables-only file.  You must pass a second parameter of

+FALSE to indicate that you do not require an image to be present.  Thus, the

+typical scenario is

+

+        create JPEG decompression object

+        set source to tables-only file

+        jpeg_read_header(&cinfo, FALSE);

+        set source to abbreviated image file

+        jpeg_read_header(&cinfo, TRUE);

+        set decompression parameters

+        jpeg_start_decompress(&cinfo);

+        read data...

+        jpeg_finish_decompress(&cinfo);

+

+In some cases, you may want to read a file without knowing whether it contains

+an image or just tables.  In that case, pass FALSE and check the return value

+from jpeg_read_header(): it will be JPEG_HEADER_OK if an image was found,

+JPEG_HEADER_TABLES_ONLY if only tables were found.  (A third return value,

+JPEG_SUSPENDED, is possible when using a suspending data source manager.)

+Note that jpeg_read_header() will not complain if you read an abbreviated

+image for which you haven't loaded the missing tables; the missing-table check

+occurs later, in jpeg_start_decompress().

+

+

+It is possible to read a series of images from a single source file by

+repeating the jpeg_read_header() ... jpeg_finish_decompress() sequence,

+without releasing/recreating the JPEG object or the data source module.

+(If you did reinitialize, any partial bufferload left in the data source

+buffer at the end of one image would be discarded, causing you to lose the

+start of the next image.)  When you use this method, stored tables are

+automatically carried forward, so some of the images can be abbreviated images

+that depend on tables from earlier images.

+

+If you intend to write a series of images into a single destination file,

+you might want to make a specialized data destination module that doesn't

+flush the output buffer at term_destination() time.  This would speed things

+up by some trifling amount.  Of course, you'd need to remember to flush the

+buffer after the last image.  You can make the later images be abbreviated

+ones by passing FALSE to jpeg_start_compress().

+

+

+Special markers

+---------------

+

+Some applications may need to insert or extract special data in the JPEG

+datastream.  The JPEG standard provides marker types "COM" (comment) and

+"APP0" through "APP15" (application) to hold application-specific data.

+Unfortunately, the use of these markers is not specified by the standard.

+COM markers are fairly widely used to hold user-supplied text.  The JFIF file

+format spec uses APP0 markers with specified initial strings to hold certain

+data.  Adobe applications use APP14 markers beginning with the string "Adobe"

+for miscellaneous data.  Other APPn markers are rarely seen, but might

+contain almost anything.

+

+If you wish to store user-supplied text, we recommend you use COM markers

+and place readable 7-bit ASCII text in them.  Newline conventions are not

+standardized --- expect to find LF (Unix style), CR/LF (DOS style), or CR

+(Mac style).  A robust COM reader should be able to cope with random binary

+garbage, including nulls, since some applications generate COM markers

+containing non-ASCII junk.  (But yours should not be one of them.)

+

+For program-supplied data, use an APPn marker, and be sure to begin it with an

+identifying string so that you can tell whether the marker is actually yours.

+It's probably best to avoid using APP0 or APP14 for any private markers.

+(NOTE: the upcoming SPIFF standard will use APP8 markers; we recommend you

+not use APP8 markers for any private purposes, either.)

+

+Keep in mind that at most 65533 bytes can be put into one marker, but you

+can have as many markers as you like.

+

+By default, the IJG compression library will write a JFIF APP0 marker if the

+selected JPEG colorspace is grayscale or YCbCr, or an Adobe APP14 marker if

+the selected colorspace is RGB, CMYK, or YCCK.  You can disable this, but

+we don't recommend it.  The decompression library will recognize JFIF and

+Adobe markers and will set the JPEG colorspace properly when one is found.

+

+

+You can write special markers immediately following the datastream header by

+calling jpeg_write_marker() after jpeg_start_compress() and before the first

+call to jpeg_write_scanlines().  When you do this, the markers appear after

+the SOI and the JFIF APP0 and Adobe APP14 markers (if written), but before

+all else.  Specify the marker type parameter as "JPEG_COM" for COM or

+"JPEG_APP0 + n" for APPn.  (Actually, jpeg_write_marker will let you write

+any marker type, but we don't recommend writing any other kinds of marker.)

+For example, to write a user comment string pointed to by comment_text:

+        jpeg_write_marker(cinfo, JPEG_COM, comment_text, strlen(comment_text));

+

+If it's not convenient to store all the marker data in memory at once,

+you can instead call jpeg_write_m_header() followed by multiple calls to

+jpeg_write_m_byte().  If you do it this way, it's your responsibility to

+call jpeg_write_m_byte() exactly the number of times given in the length

+parameter to jpeg_write_m_header().  (This method lets you empty the

+output buffer partway through a marker, which might be important when

+using a suspending data destination module.  In any case, if you are using

+a suspending destination, you should flush its buffer after inserting

+any special markers.  See "I/O suspension".)

+

+Or, if you prefer to synthesize the marker byte sequence yourself,

+you can just cram it straight into the data destination module.

+

+If you are writing JFIF 1.02 extension markers (thumbnail images), don't

+forget to set cinfo.JFIF_minor_version = 2 so that the encoder will write the

+correct JFIF version number in the JFIF header marker.  The library's default

+is to write version 1.01, but that's wrong if you insert any 1.02 extension

+markers.  (We could probably get away with just defaulting to 1.02, but there

+used to be broken decoders that would complain about unknown minor version

+numbers.  To reduce compatibility risks it's safest not to write 1.02 unless

+you are actually using 1.02 extensions.)

+

+

+When reading, two methods of handling special markers are available:

+1. You can ask the library to save the contents of COM and/or APPn markers

+into memory, and then examine them at your leisure afterwards.

+2. You can supply your own routine to process COM and/or APPn markers

+on-the-fly as they are read.

+The first method is simpler to use, especially if you are using a suspending

+data source; writing a marker processor that copes with input suspension is

+not easy (consider what happens if the marker is longer than your available

+input buffer).  However, the second method conserves memory since the marker

+data need not be kept around after it's been processed.

+

+For either method, you'd normally set up marker handling after creating a

+decompression object and before calling jpeg_read_header(), because the

+markers of interest will typically be near the head of the file and so will

+be scanned by jpeg_read_header.  Once you've established a marker handling

+method, it will be used for the life of that decompression object

+(potentially many datastreams), unless you change it.  Marker handling is

+determined separately for COM markers and for each APPn marker code.

+

+

+To save the contents of special markers in memory, call

+        jpeg_save_markers(cinfo, marker_code, length_limit)

+where marker_code is the marker type to save, JPEG_COM or JPEG_APP0+n.

+(To arrange to save all the special marker types, you need to call this

+routine 17 times, for COM and APP0-APP15.)  If the incoming marker is longer

+than length_limit data bytes, only length_limit bytes will be saved; this

+parameter allows you to avoid chewing up memory when you only need to see the

+first few bytes of a potentially large marker.  If you want to save all the

+data, set length_limit to 0xFFFF; that is enough since marker lengths are only

+16 bits.  As a special case, setting length_limit to 0 prevents that marker

+type from being saved at all.  (That is the default behavior, in fact.)

+

+After jpeg_read_header() completes, you can examine the special markers by

+following the cinfo->marker_list pointer chain.  All the special markers in

+the file appear in this list, in order of their occurrence in the file (but

+omitting any markers of types you didn't ask for).  Both the original data

+length and the saved data length are recorded for each list entry; the latter

+will not exceed length_limit for the particular marker type.  Note that these

+lengths exclude the marker length word, whereas the stored representation

+within the JPEG file includes it.  (Hence the maximum data length is really

+only 65533.)

+

+It is possible that additional special markers appear in the file beyond the

+SOS marker at which jpeg_read_header stops; if so, the marker list will be

+extended during reading of the rest of the file.  This is not expected to be

+common, however.  If you are short on memory you may want to reset the length

+limit to zero for all marker types after finishing jpeg_read_header, to

+ensure that the max_memory_to_use setting cannot be exceeded due to addition

+of later markers.

+

+The marker list remains stored until you call jpeg_finish_decompress or

+jpeg_abort, at which point the memory is freed and the list is set to empty.

+(jpeg_destroy also releases the storage, of course.)

+

+Note that the library is internally interested in APP0 and APP14 markers;

+if you try to set a small nonzero length limit on these types, the library

+will silently force the length up to the minimum it wants.  (But you can set

+a zero length limit to prevent them from being saved at all.)  Also, in a

+16-bit environment, the maximum length limit may be constrained to less than

+65533 by malloc() limitations.  It is therefore best not to assume that the

+effective length limit is exactly what you set it to be.

+

+

+If you want to supply your own marker-reading routine, you do it by calling

+jpeg_set_marker_processor().  A marker processor routine must have the

+signature

+        boolean jpeg_marker_parser_method (j_decompress_ptr cinfo)

+Although the marker code is not explicitly passed, the routine can find it

+in cinfo->unread_marker.  At the time of call, the marker proper has been

+read from the data source module.  The processor routine is responsible for

+reading the marker length word and the remaining parameter bytes, if any.

+Return TRUE to indicate success.  (FALSE should be returned only if you are

+using a suspending data source and it tells you to suspend.  See the standard

+marker processors in jdmarker.c for appropriate coding methods if you need to

+use a suspending data source.)

+

+If you override the default APP0 or APP14 processors, it is up to you to

+recognize JFIF and Adobe markers if you want colorspace recognition to occur

+properly.  We recommend copying and extending the default processors if you

+want to do that.  (A better idea is to save these marker types for later

+examination by calling jpeg_save_markers(); that method doesn't interfere

+with the library's own processing of these markers.)

+

+jpeg_set_marker_processor() and jpeg_save_markers() are mutually exclusive

+--- if you call one it overrides any previous call to the other, for the

+particular marker type specified.

+

+A simple example of an external COM processor can be found in djpeg.c.

+Also, see jpegtran.c for an example of using jpeg_save_markers.

+

+

+Raw (downsampled) image data

+----------------------------

+

+Some applications need to supply already-downsampled image data to the JPEG

+compressor, or to receive raw downsampled data from the decompressor.  The

+library supports this requirement by allowing the application to write or

+read raw data, bypassing the normal preprocessing or postprocessing steps.

+The interface is different from the standard one and is somewhat harder to

+use.  If your interest is merely in bypassing color conversion, we recommend

+that you use the standard interface and simply set jpeg_color_space =

+in_color_space (or jpeg_color_space = out_color_space for decompression).

+The mechanism described in this section is necessary only to supply or

+receive downsampled image data, in which not all components have the same

+dimensions.

+

+

+To compress raw data, you must supply the data in the colorspace to be used

+in the JPEG file (please read the earlier section on Special color spaces)

+and downsampled to the sampling factors specified in the JPEG parameters.

+You must supply the data in the format used internally by the JPEG library,

+namely a JSAMPIMAGE array.  This is an array of pointers to two-dimensional

+arrays, each of type JSAMPARRAY.  Each 2-D array holds the values for one

+color component.  This structure is necessary since the components are of

+different sizes.  If the image dimensions are not a multiple of the MCU size,

+you must also pad the data correctly (usually, this is done by replicating

+the last column and/or row).  The data must be padded to a multiple of a DCT

+block in each component: that is, each downsampled row must contain a

+multiple of 8 valid samples, and there must be a multiple of 8 sample rows

+for each component.  (For applications such as conversion of digital TV

+images, the standard image size is usually a multiple of the DCT block size,

+so that no padding need actually be done.)

+

+The procedure for compression of raw data is basically the same as normal

+compression, except that you call jpeg_write_raw_data() in place of

+jpeg_write_scanlines().  Before calling jpeg_start_compress(), you must do

+the following:

+  * Set cinfo->raw_data_in to TRUE.  (It is set FALSE by jpeg_set_defaults().)

+    This notifies the library that you will be supplying raw data.

+    Furthermore, set cinfo->do_fancy_downsampling to FALSE if you want to use

+    real downsampled data.  (It is set TRUE by jpeg_set_defaults().)

+  * Ensure jpeg_color_space is correct --- an explicit jpeg_set_colorspace()

+    call is a good idea.  Note that since color conversion is bypassed,

+    in_color_space is ignored, except that jpeg_set_defaults() uses it to

+    choose the default jpeg_color_space setting.

+  * Ensure the sampling factors, cinfo->comp_info[i].h_samp_factor and

+    cinfo->comp_info[i].v_samp_factor, are correct.  Since these indicate the

+    dimensions of the data you are supplying, it's wise to set them

+    explicitly, rather than assuming the library's defaults are what you want.

+

+To pass raw data to the library, call jpeg_write_raw_data() in place of

+jpeg_write_scanlines().  The two routines work similarly except that

+jpeg_write_raw_data takes a JSAMPIMAGE data array rather than JSAMPARRAY.

+The scanlines count passed to and returned from jpeg_write_raw_data is

+measured in terms of the component with the largest v_samp_factor.

+

+jpeg_write_raw_data() processes one MCU row per call, which is to say

+v_samp_factor*DCTSIZE sample rows of each component.  The passed num_lines

+value must be at least max_v_samp_factor*DCTSIZE, and the return value will

+be exactly that amount (or possibly some multiple of that amount, in future

+library versions).  This is true even on the last call at the bottom of the

+image; don't forget to pad your data as necessary.

+

+The required dimensions of the supplied data can be computed for each

+component as

+        cinfo->comp_info[i].width_in_blocks*DCTSIZE  samples per row

+        cinfo->comp_info[i].height_in_blocks*DCTSIZE rows in image

+after jpeg_start_compress() has initialized those fields.  If the valid data

+is smaller than this, it must be padded appropriately.  For some sampling

+factors and image sizes, additional dummy DCT blocks are inserted to make

+the image a multiple of the MCU dimensions.  The library creates such dummy

+blocks itself; it does not read them from your supplied data.  Therefore you

+need never pad by more than DCTSIZE samples.  An example may help here.

+Assume 2h2v downsampling of YCbCr data, that is

+        cinfo->comp_info[0].h_samp_factor = 2           for Y

+        cinfo->comp_info[0].v_samp_factor = 2

+        cinfo->comp_info[1].h_samp_factor = 1           for Cb

+        cinfo->comp_info[1].v_samp_factor = 1

+        cinfo->comp_info[2].h_samp_factor = 1           for Cr

+        cinfo->comp_info[2].v_samp_factor = 1

+and suppose that the nominal image dimensions (cinfo->image_width and

+cinfo->image_height) are 101x101 pixels.  Then jpeg_start_compress() will

+compute downsampled_width = 101 and width_in_blocks = 13 for Y,

+downsampled_width = 51 and width_in_blocks = 7 for Cb and Cr (and the same

+for the height fields).  You must pad the Y data to at least 13*8 = 104

+columns and rows, the Cb/Cr data to at least 7*8 = 56 columns and rows.  The

+MCU height is max_v_samp_factor = 2 DCT rows so you must pass at least 16

+scanlines on each call to jpeg_write_raw_data(), which is to say 16 actual

+sample rows of Y and 8 each of Cb and Cr.  A total of 7 MCU rows are needed,

+so you must pass a total of 7*16 = 112 "scanlines".  The last DCT block row

+of Y data is dummy, so it doesn't matter what you pass for it in the data

+arrays, but the scanlines count must total up to 112 so that all of the Cb

+and Cr data gets passed.

+

+Output suspension is supported with raw-data compression: if the data

+destination module suspends, jpeg_write_raw_data() will return 0.

+In this case the same data rows must be passed again on the next call.

+

+

+Decompression with raw data output implies bypassing all postprocessing.

+You must deal with the color space and sampling factors present in the

+incoming file.  If your application only handles, say, 2h1v YCbCr data,

+you must check for and fail on other color spaces or other sampling factors.

+The library will not convert to a different color space for you.

+

+To obtain raw data output, set cinfo->raw_data_out = TRUE before

+jpeg_start_decompress() (it is set FALSE by jpeg_read_header()).  Be sure to

+verify that the color space and sampling factors are ones you can handle.

+Furthermore, set cinfo->do_fancy_upsampling = FALSE if you want to get real

+downsampled data (it is set TRUE by jpeg_read_header()).

+Then call jpeg_read_raw_data() in place of jpeg_read_scanlines().  The

+decompression process is otherwise the same as usual.

+

+jpeg_read_raw_data() returns one MCU row per call, and thus you must pass a

+buffer of at least max_v_samp_factor*DCTSIZE scanlines (scanline counting is

+the same as for raw-data compression).  The buffer you pass must be large

+enough to hold the actual data plus padding to DCT-block boundaries.  As with

+compression, any entirely dummy DCT blocks are not processed so you need not

+allocate space for them, but the total scanline count includes them.  The

+above example of computing buffer dimensions for raw-data compression is

+equally valid for decompression.

+

+Input suspension is supported with raw-data decompression: if the data source

+module suspends, jpeg_read_raw_data() will return 0.  You can also use

+buffered-image mode to read raw data in multiple passes.

+

+

+Really raw data: DCT coefficients

+---------------------------------

+

+It is possible to read or write the contents of a JPEG file as raw DCT

+coefficients.  This facility is mainly intended for use in lossless

+transcoding between different JPEG file formats.  Other possible applications

+include lossless cropping of a JPEG image, lossless reassembly of a

+multi-strip or multi-tile TIFF/JPEG file into a single JPEG datastream, etc.

+

+To read the contents of a JPEG file as DCT coefficients, open the file and do

+jpeg_read_header() as usual.  But instead of calling jpeg_start_decompress()

+and jpeg_read_scanlines(), call jpeg_read_coefficients().  This will read the

+entire image into a set of virtual coefficient-block arrays, one array per

+component.  The return value is a pointer to an array of virtual-array

+descriptors.  Each virtual array can be accessed directly using the JPEG

+memory manager's access_virt_barray method (see Memory management, below,

+and also read structure.txt's discussion of virtual array handling).  Or,

+for simple transcoding to a different JPEG file format, the array list can

+just be handed directly to jpeg_write_coefficients().

+

+Each block in the block arrays contains quantized coefficient values in

+normal array order (not JPEG zigzag order).  The block arrays contain only

+DCT blocks containing real data; any entirely-dummy blocks added to fill out

+interleaved MCUs at the right or bottom edges of the image are discarded

+during reading and are not stored in the block arrays.  (The size of each

+block array can be determined from the width_in_blocks and height_in_blocks

+fields of the component's comp_info entry.)  This is also the data format

+expected by jpeg_write_coefficients().

+

+When you are done using the virtual arrays, call jpeg_finish_decompress()

+to release the array storage and return the decompression object to an idle

+state; or just call jpeg_destroy() if you don't need to reuse the object.

+

+If you use a suspending data source, jpeg_read_coefficients() will return

+NULL if it is forced to suspend; a non-NULL return value indicates successful

+completion.  You need not test for a NULL return value when using a

+non-suspending data source.

+

+It is also possible to call jpeg_read_coefficients() to obtain access to the

+decoder's coefficient arrays during a normal decode cycle in buffered-image

+mode.  This frammish might be useful for progressively displaying an incoming

+image and then re-encoding it without loss.  To do this, decode in buffered-

+image mode as discussed previously, then call jpeg_read_coefficients() after

+the last jpeg_finish_output() call.  The arrays will be available for your use

+until you call jpeg_finish_decompress().

+

+

+To write the contents of a JPEG file as DCT coefficients, you must provide

+the DCT coefficients stored in virtual block arrays.  You can either pass

+block arrays read from an input JPEG file by jpeg_read_coefficients(), or

+allocate virtual arrays from the JPEG compression object and fill them

+yourself.  In either case, jpeg_write_coefficients() is substituted for

+jpeg_start_compress() and jpeg_write_scanlines().  Thus the sequence is

+  * Create compression object

+  * Set all compression parameters as necessary

+  * Request virtual arrays if needed

+  * jpeg_write_coefficients()

+  * jpeg_finish_compress()

+  * Destroy or re-use compression object

+jpeg_write_coefficients() is passed a pointer to an array of virtual block

+array descriptors; the number of arrays is equal to cinfo.num_components.

+

+The virtual arrays need only have been requested, not realized, before

+jpeg_write_coefficients() is called.  A side-effect of

+jpeg_write_coefficients() is to realize any virtual arrays that have been

+requested from the compression object's memory manager.  Thus, when obtaining

+the virtual arrays from the compression object, you should fill the arrays

+after calling jpeg_write_coefficients().  The data is actually written out

+when you call jpeg_finish_compress(); jpeg_write_coefficients() only writes

+the file header.

+

+When writing raw DCT coefficients, it is crucial that the JPEG quantization

+tables and sampling factors match the way the data was encoded, or the

+resulting file will be invalid.  For transcoding from an existing JPEG file,

+we recommend using jpeg_copy_critical_parameters().  This routine initializes

+all the compression parameters to default values (like jpeg_set_defaults()),

+then copies the critical information from a source decompression object.

+The decompression object should have just been used to read the entire

+JPEG input file --- that is, it should be awaiting jpeg_finish_decompress().

+

+jpeg_write_coefficients() marks all tables stored in the compression object

+as needing to be written to the output file (thus, it acts like

+jpeg_start_compress(cinfo, TRUE)).  This is for safety's sake, to avoid

+emitting abbreviated JPEG files by accident.  If you really want to emit an

+abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables'

+individual sent_table flags, between calling jpeg_write_coefficients() and

+jpeg_finish_compress().

+

+

+Progress monitoring

+-------------------

+

+Some applications may need to regain control from the JPEG library every so

+often.  The typical use of this feature is to produce a percent-done bar or

+other progress display.  (For a simple example, see cjpeg.c or djpeg.c.)

+Although you do get control back frequently during the data-transferring pass

+(the jpeg_read_scanlines or jpeg_write_scanlines loop), any additional passes

+will occur inside jpeg_finish_compress or jpeg_start_decompress; those

+routines may take a long time to execute, and you don't get control back

+until they are done.

+

+You can define a progress-monitor routine which will be called periodically

+by the library.  No guarantees are made about how often this call will occur,

+so we don't recommend you use it for mouse tracking or anything like that.

+At present, a call will occur once per MCU row, scanline, or sample row

+group, whichever unit is convenient for the current processing mode; so the

+wider the image, the longer the time between calls.  During the data

+transferring pass, only one call occurs per call of jpeg_read_scanlines or

+jpeg_write_scanlines, so don't pass a large number of scanlines at once if

+you want fine resolution in the progress count.  (If you really need to use

+the callback mechanism for time-critical tasks like mouse tracking, you could

+insert additional calls inside some of the library's inner loops.)

+

+To establish a progress-monitor callback, create a struct jpeg_progress_mgr,

+fill in its progress_monitor field with a pointer to your callback routine,

+and set cinfo->progress to point to the struct.  The callback will be called

+whenever cinfo->progress is non-NULL.  (This pointer is set to NULL by

+jpeg_create_compress or jpeg_create_decompress; the library will not change

+it thereafter.  So if you allocate dynamic storage for the progress struct,

+make sure it will live as long as the JPEG object does.  Allocating from the

+JPEG memory manager with lifetime JPOOL_PERMANENT will work nicely.)  You

+can use the same callback routine for both compression and decompression.

+

+The jpeg_progress_mgr struct contains four fields which are set by the library:

+        long pass_counter;      /* work units completed in this pass */

+        long pass_limit;        /* total number of work units in this pass */

+        int completed_passes;   /* passes completed so far */

+        int total_passes;       /* total number of passes expected */

+During any one pass, pass_counter increases from 0 up to (not including)

+pass_limit; the step size is usually but not necessarily 1.  The pass_limit

+value may change from one pass to another.  The expected total number of

+passes is in total_passes, and the number of passes already completed is in

+completed_passes.  Thus the fraction of work completed may be estimated as

+                completed_passes + (pass_counter/pass_limit)

+                --------------------------------------------

+                                total_passes

+ignoring the fact that the passes may not be equal amounts of work.

+

+When decompressing, pass_limit can even change within a pass, because it

+depends on the number of scans in the JPEG file, which isn't always known in

+advance.  The computed fraction-of-work-done may jump suddenly (if the library

+discovers it has overestimated the number of scans) or even decrease (in the

+opposite case).  It is not wise to put great faith in the work estimate.

+

+When using the decompressor's buffered-image mode, the progress monitor work

+estimate is likely to be completely unhelpful, because the library has no way

+to know how many output passes will be demanded of it.  Currently, the library

+sets total_passes based on the assumption that there will be one more output

+pass if the input file end hasn't yet been read (jpeg_input_complete() isn't

+TRUE), but no more output passes if the file end has been reached when the

+output pass is started.  This means that total_passes will rise as additional

+output passes are requested.  If you have a way of determining the input file

+size, estimating progress based on the fraction of the file that's been read

+will probably be more useful than using the library's value.

+

+

+Memory management

+-----------------

+

+This section covers some key facts about the JPEG library's built-in memory

+manager.  For more info, please read structure.txt's section about the memory

+manager, and consult the source code if necessary.

+

+All memory and temporary file allocation within the library is done via the

+memory manager.  If necessary, you can replace the "back end" of the memory

+manager to control allocation yourself (for example, if you don't want the

+library to use malloc() and free() for some reason).

+

+Some data is allocated "permanently" and will not be freed until the JPEG

+object is destroyed.  Most data is allocated "per image" and is freed by

+jpeg_finish_compress, jpeg_finish_decompress, or jpeg_abort.  You can call the

+memory manager yourself to allocate structures that will automatically be

+freed at these times.  Typical code for this is

+  ptr = (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, size);

+Use JPOOL_PERMANENT to get storage that lasts as long as the JPEG object.

+Use alloc_large instead of alloc_small for anything bigger than a few Kbytes.

+There are also alloc_sarray and alloc_barray routines that automatically

+build 2-D sample or block arrays.

+

+The library's minimum space requirements to process an image depend on the

+image's width, but not on its height, because the library ordinarily works

+with "strip" buffers that are as wide as the image but just a few rows high.

+Some operating modes (eg, two-pass color quantization) require full-image

+buffers.  Such buffers are treated as "virtual arrays": only the current strip

+need be in memory, and the rest can be swapped out to a temporary file.

+

+If you use the simplest memory manager back end (jmemnobs.c), then no

+temporary files are used; virtual arrays are simply malloc()'d.  Images bigger

+than memory can be processed only if your system supports virtual memory.

+The other memory manager back ends support temporary files of various flavors

+and thus work in machines without virtual memory.  They may also be useful on

+Unix machines if you need to process images that exceed available swap space.

+

+When using temporary files, the library will make the in-memory buffers for

+its virtual arrays just big enough to stay within a "maximum memory" setting.

+Your application can set this limit by setting cinfo->mem->max_memory_to_use

+after creating the JPEG object.  (Of course, there is still a minimum size for

+the buffers, so the max-memory setting is effective only if it is bigger than

+the minimum space needed.)  If you allocate any large structures yourself, you

+must allocate them before jpeg_start_compress() or jpeg_start_decompress() in

+order to have them counted against the max memory limit.  Also keep in mind

+that space allocated with alloc_small() is ignored, on the assumption that

+it's too small to be worth worrying about; so a reasonable safety margin

+should be left when setting max_memory_to_use.

+

+If you use the jmemname.c or jmemdos.c memory manager back end, it is

+important to clean up the JPEG object properly to ensure that the temporary

+files get deleted.  (This is especially crucial with jmemdos.c, where the

+"temporary files" may be extended-memory segments; if they are not freed,

+DOS will require a reboot to recover the memory.)  Thus, with these memory

+managers, it's a good idea to provide a signal handler that will trap any

+early exit from your program.  The handler should call either jpeg_abort()

+or jpeg_destroy() for any active JPEG objects.  A handler is not needed with

+jmemnobs.c, and shouldn't be necessary with jmemansi.c or jmemmac.c either,

+since the C library is supposed to take care of deleting files made with

+tmpfile().

+

+

+Memory usage

+------------

+

+Working memory requirements while performing compression or decompression

+depend on image dimensions, image characteristics (such as colorspace and

+JPEG process), and operating mode (application-selected options).

+

+As of v6b, the decompressor requires:

+ 1. About 24K in more-or-less-fixed-size data.  This varies a bit depending

+    on operating mode and image characteristics (particularly color vs.

+    grayscale), but it doesn't depend on image dimensions.

+ 2. Strip buffers (of size proportional to the image width) for IDCT and

+    upsampling results.  The worst case for commonly used sampling factors

+    is about 34 bytes * width in pixels for a color image.  A grayscale image

+    only needs about 8 bytes per pixel column.

+ 3. A full-image DCT coefficient buffer is needed to decode a multi-scan JPEG

+    file (including progressive JPEGs), or whenever you select buffered-image

+    mode.  This takes 2 bytes/coefficient.  At typical 2x2 sampling, that's

+    3 bytes per pixel for a color image.  Worst case (1x1 sampling) requires

+    6 bytes/pixel.  For grayscale, figure 2 bytes/pixel.

+ 4. To perform 2-pass color quantization, the decompressor also needs a

+    128K color lookup table and a full-image pixel buffer (3 bytes/pixel).

+This does not count any memory allocated by the application, such as a

+buffer to hold the final output image.

+

+The above figures are valid for 8-bit JPEG data precision and a machine with

+32-bit ints.  For 12-bit JPEG data, double the size of the strip buffers and

+quantization pixel buffer.  The "fixed-size" data will be somewhat smaller

+with 16-bit ints, larger with 64-bit ints.  Also, CMYK or other unusual

+color spaces will require different amounts of space.

+

+The full-image coefficient and pixel buffers, if needed at all, do not

+have to be fully RAM resident; you can have the library use temporary

+files instead when the total memory usage would exceed a limit you set.

+(But if your OS supports virtual memory, it's probably better to just use

+jmemnobs and let the OS do the swapping.)

+

+The compressor's memory requirements are similar, except that it has no need

+for color quantization.  Also, it needs a full-image DCT coefficient buffer

+if Huffman-table optimization is asked for, even if progressive mode is not

+requested.

+

+If you need more detailed information about memory usage in a particular

+situation, you can enable the MEM_STATS code in jmemmgr.c.

+

+

+Library compile-time options

+----------------------------

+

+A number of compile-time options are available by modifying jmorecfg.h.

+

+The JPEG standard provides for both the baseline 8-bit DCT process and

+a 12-bit DCT process.  The IJG code supports 12-bit JPEG if you define

+BITS_IN_JSAMPLE as 12 rather than 8.  Note that this causes JSAMPLE to be

+larger than a char, so it affects the surrounding application's image data.

+The sample applications cjpeg and djpeg can support 12-bit mode only for PPM

+and GIF file formats; you must disable the other file formats to compile a

+12-bit cjpeg or djpeg.  (install.txt has more information about that.)

+At present, a 12-bit library can handle *only* 12-bit images, not both

+precisions.  (If you need to include both 8- and 12-bit libraries in a single

+application, you could probably do it by defining NEED_SHORT_EXTERNAL_NAMES

+for just one of the copies.  You'd have to access the 8-bit and 12-bit copies

+from separate application source files.  This is untested ... if you try it,

+we'd like to hear whether it works!)

+

+Note that a 12-bit library always compresses in Huffman optimization mode,

+in order to generate valid Huffman tables.  This is necessary because our

+default Huffman tables only cover 8-bit data.  If you need to output 12-bit

+files in one pass, you'll have to supply suitable default Huffman tables.

+You may also want to supply your own DCT quantization tables; the existing

+quality-scaling code has been developed for 8-bit use, and probably doesn't

+generate especially good tables for 12-bit.

+

+The maximum number of components (color channels) in the image is determined

+by MAX_COMPONENTS.  The JPEG standard allows up to 255 components, but we

+expect that few applications will need more than four or so.

+

+On machines with unusual data type sizes, you may be able to improve

+performance or reduce memory space by tweaking the various typedefs in

+jmorecfg.h.  In particular, on some RISC CPUs, access to arrays of "short"s

+is quite slow; consider trading memory for speed by making JCOEF, INT16, and

+UINT16 be "int" or "unsigned int".  UINT8 is also a candidate to become int.

+You probably don't want to make JSAMPLE be int unless you have lots of memory

+to burn.

+

+You can reduce the size of the library by compiling out various optional

+functions.  To do this, undefine xxx_SUPPORTED symbols as necessary.

+

+You can also save a few K by not having text error messages in the library;

+the standard error message table occupies about 5Kb.  This is particularly

+reasonable for embedded applications where there's no good way to display 

+a message anyway.  To do this, remove the creation of the message table

+(jpeg_std_message_table[]) from jerror.c, and alter format_message to do

+something reasonable without it.  You could output the numeric value of the

+message code number, for example.  If you do this, you can also save a couple

+more K by modifying the TRACEMSn() macros in jerror.h to expand to nothing;

+you don't need trace capability anyway, right?

+

+

+Portability considerations

+--------------------------

+

+The JPEG library has been written to be extremely portable; the sample

+applications cjpeg and djpeg are slightly less so.  This section summarizes

+the design goals in this area.  (If you encounter any bugs that cause the

+library to be less portable than is claimed here, we'd appreciate hearing

+about them.)

+

+The code works fine on ANSI C, C++, and pre-ANSI C compilers, using any of

+the popular system include file setups, and some not-so-popular ones too.

+See install.txt for configuration procedures.

+

+The code is not dependent on the exact sizes of the C data types.  As

+distributed, we make the assumptions that

+        char    is at least 8 bits wide

+        short   is at least 16 bits wide

+        int     is at least 16 bits wide

+        long    is at least 32 bits wide

+(These are the minimum requirements of the ANSI C standard.)  Wider types will

+work fine, although memory may be used inefficiently if char is much larger

+than 8 bits or short is much bigger than 16 bits.  The code should work

+equally well with 16- or 32-bit ints.

+

+In a system where these assumptions are not met, you may be able to make the

+code work by modifying the typedefs in jmorecfg.h.  However, you will probably

+have difficulty if int is less than 16 bits wide, since references to plain

+int abound in the code.

+

+char can be either signed or unsigned, although the code runs faster if an

+unsigned char type is available.  If char is wider than 8 bits, you will need

+to redefine JOCTET and/or provide custom data source/destination managers so

+that JOCTET represents exactly 8 bits of data on external storage.

+

+The JPEG library proper does not assume ASCII representation of characters.

+But some of the image file I/O modules in cjpeg/djpeg do have ASCII

+dependencies in file-header manipulation; so does cjpeg's select_file_type()

+routine.

+

+The JPEG library does not rely heavily on the C library.  In particular, C

+stdio is used only by the data source/destination modules and the error

+handler, all of which are application-replaceable.  (cjpeg/djpeg are more

+heavily dependent on stdio.)  malloc and free are called only from the memory

+manager "back end" module, so you can use a different memory allocator by

+replacing that one file.

+

+The code generally assumes that C names must be unique in the first 15

+characters.  However, global function names can be made unique in the

+first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES.

+

+More info about porting the code may be gleaned by reading jconfig.txt,

+jmorecfg.h, and jinclude.h.

+

+

+Notes for MS-DOS implementors

+-----------------------------

+

+The IJG code is designed to work efficiently in 80x86 "small" or "medium"

+memory models (i.e., data pointers are 16 bits unless explicitly declared

+"far"; code pointers can be either size).  You may be able to use small

+model to compile cjpeg or djpeg by itself, but you will probably have to use

+medium model for any larger application.  This won't make much difference in

+performance.  You *will* take a noticeable performance hit if you use a

+large-data memory model (perhaps 10%-25%), and you should avoid "huge" model

+if at all possible.

+

+The JPEG library typically needs 2Kb-3Kb of stack space.  It will also

+malloc about 20K-30K of near heap space while executing (and lots of far

+heap, but that doesn't count in this calculation).  This figure will vary

+depending on selected operating mode, and to a lesser extent on image size.

+There is also about 5Kb-6Kb of constant data which will be allocated in the

+near data segment (about 4Kb of this is the error message table).

+Thus you have perhaps 20K available for other modules' static data and near

+heap space before you need to go to a larger memory model.  The C library's

+static data will account for several K of this, but that still leaves a good

+deal for your needs.  (If you are tight on space, you could reduce the sizes

+of the I/O buffers allocated by jdatasrc.c and jdatadst.c, say from 4K to

+1K.  Another possibility is to move the error message table to far memory;

+this should be doable with only localized hacking on jerror.c.)

+

+About 2K of the near heap space is "permanent" memory that will not be

+released until you destroy the JPEG object.  This is only an issue if you

+save a JPEG object between compression or decompression operations.

+

+Far data space may also be a tight resource when you are dealing with large

+images.  The most memory-intensive case is decompression with two-pass color

+quantization, or single-pass quantization to an externally supplied color

+map.  This requires a 128Kb color lookup table plus strip buffers amounting

+to about 40 bytes per column for typical sampling ratios (eg, about 25600

+bytes for a 640-pixel-wide image).  You may not be able to process wide

+images if you have large data structures of your own.

+

+Of course, all of these concerns vanish if you use a 32-bit flat-memory-model

+compiler, such as DJGPP or Watcom C.  We highly recommend flat model if you

+can use it; the JPEG library is significantly faster in flat model.

+   - Backslashes not followed by double quotes are not special.

+   - But 2*n+1 backslashes followed by a double quote become

+     n backslashes followed by a double quote (n >= 0):

+# and has been tested with Borland C++ for OS/2.

+# Watch out for optimization bugs in the OS/2 compilers --- see notes below!

+# Thanks to Tom Wright and Ge' Weijers (original DOS) and

+# You may need to adjust these cc options:

+# Uncomment for generic 68000 code (will work on any Amiga)

+ARCHFLAGS= -sn

+

+# Uncomment for 68020/68030 code (faster, but won't run on 68000 CPU)

+#ARCHFLAGS= -c2

+# Makefile for Independent JPEG Group's software

+

+# This makefile is for Microsoft C for MS-DOS, version 6.00A and up.

+# Use NMAKE, not Microsoft's brain-damaged MAKE.

+# Thanks to Alan Wright and Chris Turner of Olivetti Research Ltd.

+

+# Read installation instructions before saying "nmake" !!

+

+# You may need to adjust these compiler options:

+CFLAGS = -AM -Oecigt -Gs -W3

+# -AM medium memory model (or use -AS for small model, if you remove features)

+# -Oecigt -Gs  maximum safe optimisation (-Ol has bugs in MSC 6.00A)

+# -W3 warning level 3

+# You might also want to add -G2 if you have an 80286, etc.

+# Generally, we recommend defining any configuration symbols in jconfig.h,

+# NOT via -D switches here.

+

+# Jan-Herman Buining suggests the following switches for MS C 8.0 and a 486:

+# CFLAGS = /AM /f- /FPi87 /G3 /Gs /Gy /Ob1 /Oc /Oe /Og /Oi /Ol /On /Oo /Ot \

+#          /OV4 /W3

+# except for jquant1.c, which must be compiled with /Oo- to avoid a compiler

+# crash.

+

+# Ingar Steinsland suggests the following switches when building

+# a 16-bit Windows DLL:

+# CFLAGS = -ALw -Gsw -Zpe -W3 -O2 -Zi -Zd

+

+# Put here the object file name for the correct system-dependent memory

+# manager file.  For DOS, we recommend jmemdos.c and jmemdosa.asm.

+# (But not for Windows; see install.txt if you use this makefile for Windows.)

+SYSDEPMEM= jmemdos.obj jmemdosa.obj

+# SYSDEPMEMLIB must list the same files with "+" signs for the librarian.

+SYSDEPMEMLIB= +jmemdos.obj +jmemdosa.obj

+# End of configurable options.

+# You may need to adjust these cc options:

+CFLAGS= -O

+# Generally, we recommend defining any configuration symbols in jconfig.h,

+# NOT via -D switches here.

+# However, any special defines for ansi2knr.c may be included here:

+ANSI2KNRFLAGS=

+# Link-time cc options:

+LDFLAGS= 

+

+# To link any special libraries, add the necessary -l commands here.

+LDLIBS= 

+

+# Put here the object file name for the correct system-dependent memory

+# manager file.  For Unix this is usually jmemnobs.o, but you may want

+# to use jmemansi.o or jmemname.o if you have limited swap space.

+# Makefile for Independent JPEG Group's software

+

+# This makefile is for Microsoft Visual C++ on Windows NT (and 95?).

+# It builds the IJG library as a statically linkable library (.LIB),

+# and builds the sample applications as console-mode apps.

+# Thanks to Xingong Chang, Raymond Everly and others.

+

+# Read installation instructions before saying "nmake" !!

+# To build an optimized library without debug info, say "nmake nodebug=1".

+

+# Pull in standard variable definitions

+!include <win32.mak>

+

+# You may want to adjust these compiler options:

+CFLAGS= $(cflags) $(cdebug) $(cvars) -I.

+# Generally, we recommend defining any configuration symbols in jconfig.h,

+# NOT via -D switches here.

+

+# Link-time options:

+LDFLAGS= $(ldebug) $(conlflags)

+

+# To link any special libraries, add the necessary commands here.

+LDLIBS= $(conlibs)

+

+# Put here the object file name for the correct system-dependent memory

+# manager file.  For NT we suggest jmemnobs.obj, which expects the OS to

+# provide adequate virtual memory.

+SYSDEPMEM= jmemnobs.obj

+

+# miscellaneous OS-dependent stuff

+# file deletion command

+RM= del

+

+# End of configurable options.

+

+

+$! Makefile for Independent JPEG Group's software

+$!

+$! This is a command procedure for Digital VMS systems that do not have MMS.

+$! It builds the JPEG software by brute force, recompiling everything whether

+$! or not it is necessary.  It then runs the basic self-test.

+$! Thanks to Rick Dyson (dyson@iowasp.physics.uiowa.edu)

+$! and Tim Bell (tbell@netcom.com) for their help.

+$!

+$! Read installation instructions before running this!!

+-- makeproj.mac

+-- This AppleScript builds Code Warrior PRO Release 2 project files for the

+-- libjpeg library as well as the test programs 'cjpeg', 'djpeg', 'jpegtran'.

+-- (We'd distribute real project files, except they're not text

+-- and would create maintenance headaches.)

+--

+-- The script then compiles and links the library and the test programs.

+-- NOTE: if you haven't already created a 'jconfig.h' file, the script

+-- automatically copies 'jconfig.mac' to 'jconfig.h'.

+--

+-- To use this script, you must have AppleScript 1.1 or later installed

+-- and a suitable AppleScript editor like Script Editor or Script Debugger

+-- (http://www.latenightsw.com). Open this file with your AppleScript

+-- editor and execute the "run" command to build the projects.

+--

+-- Thanks to Dan Sears and Don Agro for this script.

+-- Questions about this script can be addressed to dogpark@interlog.com

+ * Modified 2009-2010 by Guido Vollbeding.

+ * This file is part of the Independent JPEG Group's software.

+ * For conditions of distribution and use, see the accompanying README file.

+ *

+ * This file contains routines to read input images in Microsoft "BMP"

+ * format (MS Windows 3.x, OS/2 1.x, and OS/2 2.x flavors).

+ * Currently, only 8-bit and 24-bit images are supported, not 1-bit or

+ * 4-bit (feeding such low-depth images into JPEG would be silly anyway).

+ * Also, we don't support RLE-compressed files.

+ *

+ * These routines may need modification for non-Unix environments or

+ * specialized applications.  As they stand, they assume input from

+ * an ordinary stdio stream.  They further assume that reading begins

+ * at the start of the file; start_input may need work if the

+ * user interface has already read some data (e.g., to determine that

+ * the file is indeed BMP format).

+ *

+ * This code contributed by James Arthur Boucher.

+.SH NAME

+rdjpgcom \- display text comments from a JPEG file

+.SH SYNOPSIS

+.B rdjpgcom

+[

+.B \-raw

+]

+[

+.B \-verbose

+]

+[

+.I filename

+]

+.LP

+.SH DESCRIPTION

+.LP

+.B rdjpgcom

+reads the named JPEG/JFIF file, or the standard input if no file is named,

+and prints any text comments found in the file on the standard output.

+.PP

+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.

+Although the standard doesn't actually define what COM blocks are for, they

+are widely used to hold user-supplied text strings.  This lets you add

+annotations, titles, index terms, etc to your JPEG files, and later retrieve

+them as text.  COM blocks do not interfere with the image stored in the JPEG

+file.  The maximum size of a COM block is 64K, but you can have as many of

+them as you like in one JPEG file.

+.SH OPTIONS

+.TP

+.B \-raw

+Normally

+.B rdjpgcom

+escapes non-printable characters in comments, for security reasons.

+This option avoids that.

+.PP

+.B \-verbose

+Causes

+.B rdjpgcom

+to also display the JPEG image dimensions.

+.PP

+Switch names may be abbreviated, and are not case sensitive.

+.SH HINTS

+.B rdjpgcom

+does not depend on the IJG JPEG library.  Its source code is intended as an

+illustration of the minimum amount of code required to parse a JPEG file

+header correctly.

+.PP

+In

+.B \-verbose

+mode,

+.B rdjpgcom

+will also attempt to print the contents of any "APP12" markers as text.

+Some digital cameras produce APP12 markers containing useful textual

+information.  If you like, you can modify the source code to print

+other APPn marker types as well.

+IJG JPEG LIBRARY:  SYSTEM ARCHITECTURE

+

+Copyright (C) 1991-2012, Thomas G. Lane, Guido Vollbeding.

+This file is part of the Independent JPEG Group's software.

+For conditions of distribution and use, see the accompanying README file.

+

+

+This file provides an overview of the architecture of the IJG JPEG software;

+that is, the functions of the various modules in the system and the interfaces

+between modules.  For more precise details about any data structure or calling

+convention, see the include files and comments in the source code.

+

+We assume that the reader is already somewhat familiar with the JPEG standard.

+The README file includes references for learning about JPEG.  The file

+libjpeg.txt describes the library from the viewpoint of an application

+programmer using the library; it's best to read that file before this one.

+Also, the file coderules.txt describes the coding style conventions we use.

+

+In this document, JPEG-specific terminology follows the JPEG standard:

+  A "component" means a color channel, e.g., Red or Luminance.

+  A "sample" is a single component value (i.e., one number in the image data).

+  A "coefficient" is a frequency coefficient (a DCT transform output number).

+  A "block" is an array of samples or coefficients.

+  An "MCU" (minimum coded unit) is an interleaved set of blocks of size

+        determined by the sampling factors, or a single block in a

+        noninterleaved scan.

+We do not use the terms "pixel" and "sample" interchangeably.  When we say

+pixel, we mean an element of the full-size image, while a sample is an element

+of the downsampled image.  Thus the number of samples may vary across

+components while the number of pixels does not.  (This terminology is not used

+rigorously throughout the code, but it is used in places where confusion would

+otherwise result.)

+

+

+*** System features ***

+

+The IJG distribution contains two parts:

+  * A subroutine library for JPEG compression and decompression.

+  * cjpeg/djpeg, two sample applications that use the library to transform

+    JFIF JPEG files to and from several other image formats.

+cjpeg/djpeg are of no great intellectual complexity: they merely add a simple

+command-line user interface and I/O routines for several uncompressed image

+formats.  This document concentrates on the library itself.

+

+We desire the library to be capable of supporting all JPEG baseline, extended

+sequential, and progressive DCT processes.  The library does not support the

+hierarchical or lossless processes defined in the standard.

+

+Within these limits, any set of compression parameters allowed by the JPEG

+spec should be readable for decompression.  (We can be more restrictive about

+what formats we can generate.)  Although the system design allows for all

+parameter values, some uncommon settings are not yet implemented and may

+never be; nonintegral sampling ratios are the prime example.  Furthermore,

+we treat 8-bit vs. 12-bit data precision as a compile-time switch, not a

+run-time option, because most machines can store 8-bit pixels much more

+compactly than 12-bit.

+

+By itself, the library handles only interchange JPEG datastreams --- in

+particular the widely used JFIF file format.  The library can be used by

+surrounding code to process interchange or abbreviated JPEG datastreams that

+are embedded in more complex file formats.  (For example, libtiff uses this

+library to implement JPEG compression within the TIFF file format.)

+

+The library includes a substantial amount of code that is not covered by the

+JPEG standard but is necessary for typical applications of JPEG.  These

+functions preprocess the image before JPEG compression or postprocess it after

+decompression.  They include colorspace conversion, downsampling/upsampling,

+and color quantization.  This code can be omitted if not needed.

+

+A wide range of quality vs. speed tradeoffs are possible in JPEG processing,

+and even more so in decompression postprocessing.  The decompression library

+provides multiple implementations that cover most of the useful tradeoffs,

+ranging from very-high-quality down to fast-preview operation.  On the

+compression side we have generally not provided low-quality choices, since

+compression is normally less time-critical.  It should be understood that the

+low-quality modes may not meet the JPEG standard's accuracy requirements;

+nonetheless, they are useful for viewers.

+

+

+*** Portability issues ***

+

+Portability is an essential requirement for the library.  The key portability

+issues that show up at the level of system architecture are:

+

+1.  Memory usage.  We want the code to be able to run on PC-class machines

+with limited memory.  Images should therefore be processed sequentially (in

+strips), to avoid holding the whole image in memory at once.  Where a

+full-image buffer is necessary, we should be able to use either virtual memory

+or temporary files.

+

+2.  Near/far pointer distinction.  To run efficiently on 80x86 machines, the

+code should distinguish "small" objects (kept in near data space) from

+"large" ones (kept in far data space).  This is an annoying restriction, but

+fortunately it does not impact code quality for less brain-damaged machines,

+and the source code clutter turns out to be minimal with sufficient use of

+pointer typedefs.

+

+3. Data precision.  We assume that "char" is at least 8 bits, "short" and

+"int" at least 16, "long" at least 32.  The code will work fine with larger

+data sizes, although memory may be used inefficiently in some cases.  However,

+the JPEG compressed datastream must ultimately appear on external storage as a

+sequence of 8-bit bytes if it is to conform to the standard.  This may pose a

+problem on machines where char is wider than 8 bits.  The library represents

+compressed data as an array of values of typedef JOCTET.  If no data type

+exactly 8 bits wide is available, custom data source and data destination

+modules must be written to unpack and pack the chosen JOCTET datatype into

+8-bit external representation.

+

+

+*** System overview ***

+

+The compressor and decompressor are each divided into two main sections:

+the JPEG compressor or decompressor proper, and the preprocessing or

+postprocessing functions.  The interface between these two sections is the

+image data that the official JPEG spec regards as its input or output: this

+data is in the colorspace to be used for compression, and it is downsampled

+to the sampling factors to be used.  The preprocessing and postprocessing

+steps are responsible for converting a normal image representation to or from

+this form.  (Those few applications that want to deal with YCbCr downsampled

+data can skip the preprocessing or postprocessing step.)

+

+Looking more closely, the compressor library contains the following main

+elements:

+

+  Preprocessing:

+    * Color space conversion (e.g., RGB to YCbCr).

+    * Edge expansion and downsampling.  Optionally, this step can do simple

+      smoothing --- this is often helpful for low-quality source data.

+  JPEG proper:

+    * MCU assembly, DCT, quantization.

+    * Entropy coding (sequential or progressive, Huffman or arithmetic).

+

+In addition to these modules we need overall control, marker generation,

+and support code (memory management & error handling).  There is also a

+module responsible for physically writing the output data --- typically

+this is just an interface to fwrite(), but some applications may need to

+do something else with the data.

+

+The decompressor library contains the following main elements:

+

+  JPEG proper:

+    * Entropy decoding (sequential or progressive, Huffman or arithmetic).

+    * Dequantization, inverse DCT, MCU disassembly.

+  Postprocessing:

+    * Upsampling.  Optionally, this step may be able to do more general

+      rescaling of the image.

+    * Color space conversion (e.g., YCbCr to RGB).  This step may also

+      provide gamma adjustment [ currently it does not ].

+    * Optional color quantization (e.g., reduction to 256 colors).

+    * Optional color precision reduction (e.g., 24-bit to 15-bit color).

+      [This feature is not currently implemented.]

+

+We also need overall control, marker parsing, and a data source module.

+The support code (memory management & error handling) can be shared with

+the compression half of the library.

+

+There may be several implementations of each of these elements, particularly

+in the decompressor, where a wide range of speed/quality tradeoffs is very

+useful.  It must be understood that some of the best speedups involve

+merging adjacent steps in the pipeline.  For example, upsampling, color space

+conversion, and color quantization might all be done at once when using a

+low-quality ordered-dither technique.  The system architecture is designed to

+allow such merging where appropriate.

+

+

+Note: it is convenient to regard edge expansion (padding to block boundaries)

+as a preprocessing/postprocessing function, even though the JPEG spec includes

+it in compression/decompression.  We do this because downsampling/upsampling

+can be simplified a little if they work on padded data: it's not necessary to

+have special cases at the right and bottom edges.  Therefore the interface

+buffer is always an integral number of blocks wide and high, and we expect

+compression preprocessing to pad the source data properly.  Padding will occur

+only to the next block (N-sample) boundary.  In an interleaved-scan situation,

+additional dummy blocks may be used to fill out MCUs, but the MCU assembly and

+disassembly logic will create or discard these blocks internally.  (This is

+advantageous for speed reasons, since we avoid DCTing the dummy blocks.

+It also permits a small reduction in file size, because the compressor can

+choose dummy block contents so as to minimize their size in compressed form.

+Finally, it makes the interface buffer specification independent of whether

+the file is actually interleaved or not.)  Applications that wish to deal

+directly with the downsampled data must provide similar buffering and padding

+for odd-sized images.

+

+

+*** Poor man's object-oriented programming ***

+

+It should be clear by now that we have a lot of quasi-independent processing

+steps, many of which have several possible behaviors.  To avoid cluttering the

+code with lots of switch statements, we use a simple form of object-style

+programming to separate out the different possibilities.

+

+For example, two different color quantization algorithms could be implemented

+as two separate modules that present the same external interface; at runtime,

+the calling code will access the proper module indirectly through an "object".

+

+We can get the limited features we need while staying within portable C.

+The basic tool is a function pointer.  An "object" is just a struct

+containing one or more function pointer fields, each of which corresponds to

+a method name in real object-oriented languages.  During initialization we

+fill in the function pointers with references to whichever module we have

+determined we need to use in this run.  Then invocation of the module is done

+by indirecting through a function pointer; on most machines this is no more

+expensive than a switch statement, which would be the only other way of

+making the required run-time choice.  The really significant benefit, of

+course, is keeping the source code clean and well structured.

+

+We can also arrange to have private storage that varies between different

+implementations of the same kind of object.  We do this by making all the

+module-specific object structs be separately allocated entities, which will

+be accessed via pointers in the master compression or decompression struct.

+The "public" fields or methods for a given kind of object are specified by

+a commonly known struct.  But a module's initialization code can allocate

+a larger struct that contains the common struct as its first member, plus

+additional private fields.  With appropriate pointer casting, the module's

+internal functions can access these private fields.  (For a simple example,

+see jdatadst.c, which implements the external interface specified by struct

+jpeg_destination_mgr, but adds extra fields.)

+

+(Of course this would all be a lot easier if we were using C++, but we are

+not yet prepared to assume that everyone has a C++ compiler.)

+

+An important benefit of this scheme is that it is easy to provide multiple

+versions of any method, each tuned to a particular case.  While a lot of

+precalculation might be done to select an optimal implementation of a method,

+the cost per invocation is constant.  For example, the upsampling step might

+have a "generic" method, plus one or more "hardwired" methods for the most

+popular sampling factors; the hardwired methods would be faster because they'd

+use straight-line code instead of for-loops.  The cost to determine which

+method to use is paid only once, at startup, and the selection criteria are

+hidden from the callers of the method.

+

+This plan differs a little bit from usual object-oriented structures, in that

+only one instance of each object class will exist during execution.  The

+reason for having the class structure is that on different runs we may create

+different instances (choose to execute different modules).  You can think of

+the term "method" as denoting the common interface presented by a particular

+set of interchangeable functions, and "object" as denoting a group of related

+methods, or the total shared interface behavior of a group of modules.

+

+

+*** Overall control structure ***

+

+We previously mentioned the need for overall control logic in the compression

+and decompression libraries.  In IJG implementations prior to v5, overall

+control was mostly provided by "pipeline control" modules, which proved to be

+large, unwieldy, and hard to understand.  To improve the situation, the

+control logic has been subdivided into multiple modules.  The control modules

+consist of:

+

+1. Master control for module selection and initialization.  This has two

+responsibilities:

+

+   1A.  Startup initialization at the beginning of image processing.

+        The individual processing modules to be used in this run are selected

+        and given initialization calls.

+

+   1B.  Per-pass control.  This determines how many passes will be performed

+        and calls each active processing module to configure itself

+        appropriately at the beginning of each pass.  End-of-pass processing,

+        where necessary, is also invoked from the master control module.

+

+   Method selection is partially distributed, in that a particular processing

+   module may contain several possible implementations of a particular method,

+   which it will select among when given its initialization call.  The master

+   control code need only be concerned with decisions that affect more than

+   one module.

+ 

+2. Data buffering control.  A separate control module exists for each

+   inter-processing-step data buffer.  This module is responsible for

+   invoking the processing steps that write or read that data buffer.

+

+Each buffer controller sees the world as follows:

+

+input data => processing step A => buffer => processing step B => output data

+                      |              |               |

+              ------------------ controller ------------------

+

+The controller knows the dataflow requirements of steps A and B: how much data

+they want to accept in one chunk and how much they output in one chunk.  Its

+function is to manage its buffer and call A and B at the proper times.

+

+A data buffer control module may itself be viewed as a processing step by a

+higher-level control module; thus the control modules form a binary tree with

+elementary processing steps at the leaves of the tree.

+

+The control modules are objects.  A considerable amount of flexibility can

+be had by replacing implementations of a control module.  For example:

+* Merging of adjacent steps in the pipeline is done by replacing a control

+  module and its pair of processing-step modules with a single processing-

+  step module.  (Hence the possible merges are determined by the tree of

+  control modules.)

+* In some processing modes, a given interstep buffer need only be a "strip"

+  buffer large enough to accommodate the desired data chunk sizes.  In other

+  modes, a full-image buffer is needed and several passes are required.

+  The control module determines which kind of buffer is used and manipulates

+  virtual array buffers as needed.  One or both processing steps may be

+  unaware of the multi-pass behavior.

+

+In theory, we might be able to make all of the data buffer controllers

+interchangeable and provide just one set of implementations for all.  In

+practice, each one contains considerable special-case processing for its

+particular job.  The buffer controller concept should be regarded as an

+overall system structuring principle, not as a complete description of the

+task performed by any one controller.

+

+

+*** Compression object structure ***

+

+Here is a sketch of the logical structure of the JPEG compression library:

+

+                                                 |-- Colorspace conversion

+                  |-- Preprocessing controller --|

+                  |                              |-- Downsampling

+Main controller --|

+                  |                            |-- Forward DCT, quantize

+                  |-- Coefficient controller --|

+                                               |-- Entropy encoding

+

+This sketch also describes the flow of control (subroutine calls) during

+typical image data processing.  Each of the components shown in the diagram is

+an "object" which may have several different implementations available.  One

+or more source code files contain the actual implementation(s) of each object.

+

+The objects shown above are:

+

+* Main controller: buffer controller for the subsampled-data buffer, which

+  holds the preprocessed input data.  This controller invokes preprocessing to

+  fill the subsampled-data buffer, and JPEG compression to empty it.  There is

+  usually no need for a full-image buffer here; a strip buffer is adequate.

+

+* Preprocessing controller: buffer controller for the downsampling input data

+  buffer, which lies between colorspace conversion and downsampling.  Note

+  that a unified conversion/downsampling module would probably replace this

+  controller entirely.

+

+* Colorspace conversion: converts application image data into the desired

+  JPEG color space; also changes the data from pixel-interleaved layout to

+  separate component planes.  Processes one pixel row at a time.

+

+* Downsampling: performs reduction of chroma components as required.

+  Optionally may perform pixel-level smoothing as well.  Processes a "row

+  group" at a time, where a row group is defined as Vmax pixel rows of each

+  component before downsampling, and Vk sample rows afterwards (remember Vk

+  differs across components).  Some downsampling or smoothing algorithms may

+  require context rows above and below the current row group; the

+  preprocessing controller is responsible for supplying these rows via proper

+  buffering.  The downsampler is responsible for edge expansion at the right

+  edge (i.e., extending each sample row to a multiple of N samples); but the

+  preprocessing controller is responsible for vertical edge expansion (i.e.,

+  duplicating the bottom sample row as needed to make a multiple of N rows).

+

+* Coefficient controller: buffer controller for the DCT-coefficient data.

+  This controller handles MCU assembly, including insertion of dummy DCT

+  blocks when needed at the right or bottom edge.  When performing

+  Huffman-code optimization or emitting a multiscan JPEG file, this

+  controller is responsible for buffering the full image.  The equivalent of

+  one fully interleaved MCU row of subsampled data is processed per call,

+  even when the JPEG file is noninterleaved.

+

+* Forward DCT and quantization: Perform DCT, quantize, and emit coefficients.

+  Works on one or more DCT blocks at a time.  (Note: the coefficients are now

+  emitted in normal array order, which the entropy encoder is expected to

+  convert to zigzag order as necessary.  Prior versions of the IJG code did

+  the conversion to zigzag order within the quantization step.)

+

+* Entropy encoding: Perform Huffman or arithmetic entropy coding and emit the

+  coded data to the data destination module.  Works on one MCU per call.

+  For progressive JPEG, the same DCT blocks are fed to the entropy coder

+  during each pass, and the coder must emit the appropriate subset of

+  coefficients.

+

+In addition to the above objects, the compression library includes these

+objects:

+

+* Master control: determines the number of passes required, controls overall

+  and per-pass initialization of the other modules.

+

+* Marker writing: generates JPEG markers (except for RSTn, which is emitted

+  by the entropy encoder when needed).

+

+* Data destination manager: writes the output JPEG datastream to its final

+  destination (e.g., a file).  The destination manager supplied with the

+  library knows how to write to a stdio stream or to a memory buffer;

+  for other behaviors, the surrounding application may provide its own

+  destination manager.

+

+* Memory manager: allocates and releases memory, controls virtual arrays

+  (with backing store management, where required).

+

+* Error handler: performs formatting and output of error and trace messages;

+  determines handling of nonfatal errors.  The surrounding application may

+  override some or all of this object's methods to change error handling.

+

+* Progress monitor: supports output of "percent-done" progress reports.

+  This object represents an optional callback to the surrounding application:

+  if wanted, it must be supplied by the application.

+

+The error handler, destination manager, and progress monitor objects are

+defined as separate objects in order to simplify application-specific

+customization of the JPEG library.  A surrounding application may override

+individual methods or supply its own all-new implementation of one of these

+objects.  The object interfaces for these objects are therefore treated as

+part of the application interface of the library, whereas the other objects

+are internal to the library.

+

+The error handler and memory manager are shared by JPEG compression and

+decompression; the progress monitor, if used, may be shared as well.

+

+

+*** Decompression object structure ***

+

+Here is a sketch of the logical structure of the JPEG decompression library:

+

+                                               |-- Entropy decoding

+                  |-- Coefficient controller --|

+                  |                            |-- Dequantize, Inverse DCT

+Main controller --|

+                  |                               |-- Upsampling

+                  |-- Postprocessing controller --|   |-- Colorspace conversion

+                                                  |-- Color quantization

+                                                  |-- Color precision reduction

+

+As before, this diagram also represents typical control flow.  The objects

+shown are:

+

+* Main controller: buffer controller for the subsampled-data buffer, which

+  holds the output of JPEG decompression proper.  This controller's primary

+  task is to feed the postprocessing procedure.  Some upsampling algorithms

+  may require context rows above and below the current row group; when this

+  is true, the main controller is responsible for managing its buffer so as

+  to make context rows available.  In the current design, the main buffer is

+  always a strip buffer; a full-image buffer is never required.

+

+* Coefficient controller: buffer controller for the DCT-coefficient data.

+  This controller handles MCU disassembly, including deletion of any dummy

+  DCT blocks at the right or bottom edge.  When reading a multiscan JPEG

+  file, this controller is responsible for buffering the full image.

+  (Buffering DCT coefficients, rather than samples, is necessary to support

+  progressive JPEG.)  The equivalent of one fully interleaved MCU row of

+  subsampled data is processed per call, even when the source JPEG file is

+  noninterleaved.

+

+* Entropy decoding: Read coded data from the data source module and perform

+  Huffman or arithmetic entropy decoding.  Works on one MCU per call.

+  For progressive JPEG decoding, the coefficient controller supplies the prior

+  coefficients of each MCU (initially all zeroes), which the entropy decoder

+  modifies in each scan.

+

+* Dequantization and inverse DCT: like it says.  Note that the coefficients

+  buffered by the coefficient controller have NOT been dequantized; we

+  merge dequantization and inverse DCT into a single step for speed reasons.

+  When scaled-down output is asked for, simplified DCT algorithms may be used

+  that need fewer coefficients and emit fewer samples per DCT block, not the

+  full 8x8.  Works on one DCT block at a time.

+

+* Postprocessing controller: buffer controller for the color quantization

+  input buffer, when quantization is in use.  (Without quantization, this

+  controller just calls the upsampler.)  For two-pass quantization, this

+  controller is responsible for buffering the full-image data.

+

+* Upsampling: restores chroma components to full size.  (May support more

+  general output rescaling, too.  Note that if undersized DCT outputs have

+  been emitted by the DCT module, this module must adjust so that properly

+  sized outputs are created.)  Works on one row group at a time.  This module

+  also calls the color conversion module, so its top level is effectively a

+  buffer controller for the upsampling->color conversion buffer.  However, in

+  all but the highest-quality operating modes, upsampling and color

+  conversion are likely to be merged into a single step.

+

+* Colorspace conversion: convert from JPEG color space to output color space,

+  and change data layout from separate component planes to pixel-interleaved.

+  Works on one pixel row at a time.

+

+* Color quantization: reduce the data to colormapped form, using either an

+  externally specified colormap or an internally generated one.  This module

+  is not used for full-color output.  Works on one pixel row at a time; may

+  require two passes to generate a color map.  Note that the output will

+  always be a single component representing colormap indexes.  In the current

+  design, the output values are JSAMPLEs, so an 8-bit compilation cannot

+  quantize to more than 256 colors.  This is unlikely to be a problem in

+  practice.

+

+* Color reduction: this module handles color precision reduction, e.g.,

+  generating 15-bit color (5 bits/primary) from JPEG's 24-bit output.

+  Not quite clear yet how this should be handled... should we merge it with

+  colorspace conversion???

+

+Note that some high-speed operating modes might condense the entire

+postprocessing sequence to a single module (upsample, color convert, and

+quantize in one step).

+

+In addition to the above objects, the decompression library includes these

+objects:

+

+* Master control: determines the number of passes required, controls overall

+  and per-pass initialization of the other modules.  This is subdivided into

+  input and output control: jdinput.c controls only input-side processing,

+  while jdmaster.c handles overall initialization and output-side control.

+

+* Marker reading: decodes JPEG markers (except for RSTn).

+

+* Data source manager: supplies the input JPEG datastream.  The source

+  manager supplied with the library knows how to read from a stdio stream

+  or from a memory buffer;  for other behaviors, the surrounding application

+  may provide its own source manager.

+

+* Memory manager: same as for compression library.

+

+* Error handler: same as for compression library.

+

+* Progress monitor: same as for compression library.

+

+As with compression, the data source manager, error handler, and progress

+monitor are candidates for replacement by a surrounding application.

+

+

+*** Decompression input and output separation ***

+

+To support efficient incremental display of progressive JPEG files, the

+decompressor is divided into two sections that can run independently:

+

+1. Data input includes marker parsing, entropy decoding, and input into the

+   coefficient controller's DCT coefficient buffer.  Note that this

+   processing is relatively cheap and fast.

+

+2. Data output reads from the DCT coefficient buffer and performs the IDCT

+   and all postprocessing steps.

+

+For a progressive JPEG file, the data input processing is allowed to get

+arbitrarily far ahead of the data output processing.  (This occurs only

+if the application calls jpeg_consume_input(); otherwise input and output

+run in lockstep, since the input section is called only when the output

+section needs more data.)  In this way the application can avoid making

+extra display passes when data is arriving faster than the display pass

+can run.  Furthermore, it is possible to abort an output pass without

+losing anything, since the coefficient buffer is read-only as far as the

+output section is concerned.  See libjpeg.txt for more detail.

+

+A full-image coefficient array is only created if the JPEG file has multiple

+scans (or if the application specifies buffered-image mode anyway).  When

+reading a single-scan file, the coefficient controller normally creates only

+a one-MCU buffer, so input and output processing must run in lockstep in this

+case.  jpeg_consume_input() is effectively a no-op in this situation.

+

+The main impact of dividing the decompressor in this fashion is that we must

+be very careful with shared variables in the cinfo data structure.  Each

+variable that can change during the course of decompression must be

+classified as belonging to data input or data output, and each section must

+look only at its own variables.  For example, the data output section may not

+depend on any of the variables that describe the current scan in the JPEG

+file, because these may change as the data input section advances into a new

+scan.

+

+The progress monitor is (somewhat arbitrarily) defined to treat input of the

+file as one pass when buffered-image mode is not used, and to ignore data

+input work completely when buffered-image mode is used.  Note that the

+library has no reliable way to predict the number of passes when dealing

+with a progressive JPEG file, nor can it predict the number of output passes

+in buffered-image mode.  So the work estimate is inherently bogus anyway.

+

+No comparable division is currently made in the compression library, because

+there isn't any real need for it.

+

+

+*** Data formats ***

+

+Arrays of pixel sample values use the following data structure:

+

+    typedef something JSAMPLE;          a pixel component value, 0..MAXJSAMPLE

+    typedef JSAMPLE *JSAMPROW;          ptr to a row of samples

+    typedef JSAMPROW *JSAMPARRAY;       ptr to a list of rows

+    typedef JSAMPARRAY *JSAMPIMAGE;     ptr to a list of color-component arrays

+

+The basic element type JSAMPLE will typically be one of unsigned char,

+(signed) char, or short.  Short will be used if samples wider than 8 bits are

+to be supported (this is a compile-time option).  Otherwise, unsigned char is

+used if possible.  If the compiler only supports signed chars, then it is

+necessary to mask off the value when reading.  Thus, all reads of JSAMPLE

+values must be coded as "GETJSAMPLE(value)", where the macro will be defined

+as "((value) & 0xFF)" on signed-char machines and "((int) (value))" elsewhere.

+

+With these conventions, JSAMPLE values can be assumed to be >= 0.  This helps

+simplify correct rounding during downsampling, etc.  The JPEG standard's

+specification that sample values run from -128..127 is accommodated by

+subtracting 128 from the sample value in the DCT step.  Similarly, during

+decompression the output of the IDCT step will be immediately shifted back to

+0..255.  (NB: different values are required when 12-bit samples are in use.

+The code is written in terms of MAXJSAMPLE and CENTERJSAMPLE, which will be

+defined as 255 and 128 respectively in an 8-bit implementation, and as 4095

+and 2048 in a 12-bit implementation.)

+

+We use a pointer per row, rather than a two-dimensional JSAMPLE array.  This

+choice costs only a small amount of memory and has several benefits:

+* Code using the data structure doesn't need to know the allocated width of

+  the rows.  This simplifies edge expansion/compression, since we can work

+  in an array that's wider than the logical picture width.

+* Indexing doesn't require multiplication; this is a performance win on many

+  machines.

+* Arrays with more than 64K total elements can be supported even on machines

+  where malloc() cannot allocate chunks larger than 64K.

+* The rows forming a component array may be allocated at different times

+  without extra copying.  This trick allows some speedups in smoothing steps

+  that need access to the previous and next rows.

+

+Note that each color component is stored in a separate array; we don't use the

+traditional layout in which the components of a pixel are stored together.

+This simplifies coding of modules that work on each component independently,

+because they don't need to know how many components there are.  Furthermore,

+we can read or write each component to a temporary file independently, which

+is helpful when dealing with noninterleaved JPEG files.

+

+In general, a specific sample value is accessed by code such as

+        GETJSAMPLE(image[colorcomponent][row][col])

+where col is measured from the image left edge, but row is measured from the

+first sample row currently in memory.  Either of the first two indexings can

+be precomputed by copying the relevant pointer.

+

+

+Since most image-processing applications prefer to work on images in which

+the components of a pixel are stored together, the data passed to or from the

+surrounding application uses the traditional convention: a single pixel is

+represented by N consecutive JSAMPLE values, and an image row is an array of

+(# of color components)*(image width) JSAMPLEs.  One or more rows of data can

+be represented by a pointer of type JSAMPARRAY in this scheme.  This scheme is

+converted to component-wise storage inside the JPEG library.  (Applications

+that want to skip JPEG preprocessing or postprocessing will have to contend

+with component-wise storage.)

+

+

+Arrays of DCT-coefficient values use the following data structure:

+

+    typedef short JCOEF;                a 16-bit signed integer

+    typedef JCOEF JBLOCK[DCTSIZE2];     an 8x8 block of coefficients

+    typedef JBLOCK *JBLOCKROW;          ptr to one horizontal row of 8x8 blocks

+    typedef JBLOCKROW *JBLOCKARRAY;     ptr to a list of such rows

+    typedef JBLOCKARRAY *JBLOCKIMAGE;   ptr to a list of color component arrays

+

+The underlying type is at least a 16-bit signed integer; while "short" is big

+enough on all machines of interest, on some machines it is preferable to use

+"int" for speed reasons, despite the storage cost.  Coefficients are grouped

+into 8x8 blocks (but we always use #defines DCTSIZE and DCTSIZE2 rather than

+"8" and "64").

+

+The contents of a coefficient block may be in either "natural" or zigzagged

+order, and may be true values or divided by the quantization coefficients,

+depending on where the block is in the processing pipeline.  In the current

+library, coefficient blocks are kept in natural order everywhere; the entropy

+codecs zigzag or dezigzag the data as it is written or read.  The blocks

+contain quantized coefficients everywhere outside the DCT/IDCT subsystems.

+(This latter decision may need to be revisited to support variable

+quantization a la JPEG Part 3.)

+

+Notice that the allocation unit is now a row of 8x8 coefficient blocks,

+corresponding to N rows of samples.  Otherwise the structure is much the same

+as for samples, and for the same reasons.

+

+On machines where malloc() can't handle a request bigger than 64Kb, this data

+structure limits us to rows of less than 512 JBLOCKs, or a picture width of

+4000+ pixels.  This seems an acceptable restriction.

+

+

+On 80x86 machines, the bottom-level pointer types (JSAMPROW and JBLOCKROW)

+must be declared as "far" pointers, but the upper levels can be "near"

+(implying that the pointer lists are allocated in the DS segment).

+We use a #define symbol FAR, which expands to the "far" keyword when

+compiling on 80x86 machines and to nothing elsewhere.

+

+

+*** Suspendable processing ***

+

+In some applications it is desirable to use the JPEG library as an

+incremental, memory-to-memory filter.  In this situation the data source or

+destination may be a limited-size buffer, and we can't rely on being able to

+empty or refill the buffer at arbitrary times.  Instead the application would

+like to have control return from the library at buffer overflow/underrun, and

+then resume compression or decompression at a later time.

+

+This scenario is supported for simple cases.  (For anything more complex, we

+recommend that the application "bite the bullet" and develop real multitasking

+capability.)  The libjpeg.txt file goes into more detail about the usage and

+limitations of this capability; here we address the implications for library

+structure.

+

+The essence of the problem is that the entropy codec (coder or decoder) must

+be prepared to stop at arbitrary times.  In turn, the controllers that call

+the entropy codec must be able to stop before having produced or consumed all

+the data that they normally would handle in one call.  That part is reasonably

+straightforward: we make the controller call interfaces include "progress

+counters" which indicate the number of data chunks successfully processed, and

+we require callers to test the counter rather than just assume all of the data

+was processed.

+

+Rather than trying to restart at an arbitrary point, the current Huffman

+codecs are designed to restart at the beginning of the current MCU after a

+suspension due to buffer overflow/underrun.  At the start of each call, the

+codec's internal state is loaded from permanent storage (in the JPEG object

+structures) into local variables.  On successful completion of the MCU, the

+permanent state is updated.  (This copying is not very expensive, and may even

+lead to *improved* performance if the local variables can be registerized.)

+If a suspension occurs, the codec simply returns without updating the state,

+thus effectively reverting to the start of the MCU.  Note that this implies

+leaving some data unprocessed in the source/destination buffer (ie, the

+compressed partial MCU).  The data source/destination module interfaces are

+specified so as to make this possible.  This also implies that the data buffer

+must be large enough to hold a worst-case compressed MCU; a couple thousand

+bytes should be enough.

+

+In a successive-approximation AC refinement scan, the progressive Huffman

+decoder has to be able to undo assignments of newly nonzero coefficients if it

+suspends before the MCU is complete, since decoding requires distinguishing

+previously-zero and previously-nonzero coefficients.  This is a bit tedious

+but probably won't have much effect on performance.  Other variants of Huffman

+decoding need not worry about this, since they will just store the same values

+again if forced to repeat the MCU.

+

+This approach would probably not work for an arithmetic codec, since its

+modifiable state is quite large and couldn't be copied cheaply.  Instead it

+would have to suspend and resume exactly at the point of the buffer end.

+

+The JPEG marker reader is designed to cope with suspension at an arbitrary

+point.  It does so by backing up to the start of the marker parameter segment,

+so the data buffer must be big enough to hold the largest marker of interest.

+Again, a couple KB should be adequate.  (A special "skip" convention is used

+to bypass COM and APPn markers, so these can be larger than the buffer size

+without causing problems; otherwise a 64K buffer would be needed in the worst

+case.)

+

+The JPEG marker writer currently does *not* cope with suspension.

+We feel that this is not necessary; it is much easier simply to require

+the application to ensure there is enough buffer space before starting.  (An

+empty 2K buffer is more than sufficient for the header markers; and ensuring

+there are a dozen or two bytes available before calling jpeg_finish_compress()

+will suffice for the trailer.)  This would not work for writing multi-scan

+JPEG files, but we simply do not intend to support that capability with

+suspension.

+

+

+*** Memory manager services ***

+

+The JPEG library's memory manager controls allocation and deallocation of

+memory, and it manages large "virtual" data arrays on machines where the

+operating system does not provide virtual memory.  Note that the same

+memory manager serves both compression and decompression operations.

+

+In all cases, allocated objects are tied to a particular compression or

+decompression master record, and they will be released when that master

+record is destroyed.

+

+The memory manager does not provide explicit deallocation of objects.

+Instead, objects are created in "pools" of free storage, and a whole pool

+can be freed at once.  This approach helps prevent storage-leak bugs, and

+it speeds up operations whenever malloc/free are slow (as they often are).

+The pools can be regarded as lifetime identifiers for objects.  Two

+pools/lifetimes are defined:

+  * JPOOL_PERMANENT     lasts until master record is destroyed

+  * JPOOL_IMAGE         lasts until done with image (JPEG datastream)

+Permanent lifetime is used for parameters and tables that should be carried

+across from one datastream to another; this includes all application-visible

+parameters.  Image lifetime is used for everything else.  (A third lifetime,

+JPOOL_PASS = one processing pass, was originally planned.  However it was

+dropped as not being worthwhile.  The actual usage patterns are such that the

+peak memory usage would be about the same anyway; and having per-pass storage

+substantially complicates the virtual memory allocation rules --- see below.)

+

+The memory manager deals with three kinds of object:

+1. "Small" objects.  Typically these require no more than 10K-20K total.

+2. "Large" objects.  These may require tens to hundreds of K depending on

+   image size.  Semantically they behave the same as small objects, but we

+   distinguish them for two reasons:

+     * On MS-DOS machines, large objects are referenced by FAR pointers,

+       small objects by NEAR pointers.

+     * Pool allocation heuristics may differ for large and small objects.

+   Note that individual "large" objects cannot exceed the size allowed by

+   type size_t, which may be 64K or less on some machines.

+3. "Virtual" objects.  These are large 2-D arrays of JSAMPLEs or JBLOCKs

+   (typically large enough for the entire image being processed).  The

+   memory manager provides stripwise access to these arrays.  On machines

+   without virtual memory, the rest of the array may be swapped out to a

+   temporary file.

+

+(Note: JSAMPARRAY and JBLOCKARRAY data structures are a combination of large

+objects for the data proper and small objects for the row pointers.  For

+convenience and speed, the memory manager provides single routines to create

+these structures.  Similarly, virtual arrays include a small control block

+and a JSAMPARRAY or JBLOCKARRAY working buffer, all created with one call.)

+

+In the present implementation, virtual arrays are only permitted to have image

+lifespan.  (Permanent lifespan would not be reasonable, and pass lifespan is

+not very useful since a virtual array's raison d'etre is to store data for

+multiple passes through the image.)  We also expect that only "small" objects

+will be given permanent lifespan, though this restriction is not required by

+the memory manager.

+

+In a non-virtual-memory machine, some performance benefit can be gained by

+making the in-memory buffers for virtual arrays be as large as possible.

+(For small images, the buffers might fit entirely in memory, so blind

+swapping would be very wasteful.)  The memory manager will adjust the height

+of the buffers to fit within a prespecified maximum memory usage.  In order

+to do this in a reasonably optimal fashion, the manager needs to allocate all

+of the virtual arrays at once.  Therefore, there isn't a one-step allocation

+routine for virtual arrays; instead, there is a "request" routine that simply

+allocates the control block, and a "realize" routine (called just once) that

+determines space allocation and creates all of the actual buffers.  The

+realize routine must allow for space occupied by non-virtual large objects.

+(We don't bother to factor in the space needed for small objects, on the

+grounds that it isn't worth the trouble.)

+

+To support all this, we establish the following protocol for doing business

+with the memory manager:

+  1. Modules must request virtual arrays (which may have only image lifespan)

+     during the initial setup phase, i.e., in their jinit_xxx routines.

+  2. All "large" objects (including JSAMPARRAYs and JBLOCKARRAYs) must also be

+     allocated during initial setup.

+  3. realize_virt_arrays will be called at the completion of initial setup.

+     The above conventions ensure that sufficient information is available

+     for it to choose a good size for virtual array buffers.

+Small objects of any lifespan may be allocated at any time.  We expect that

+the total space used for small objects will be small enough to be negligible

+in the realize_virt_arrays computation.

+

+In a virtual-memory machine, we simply pretend that the available space is

+infinite, thus causing realize_virt_arrays to decide that it can allocate all

+the virtual arrays as full-size in-memory buffers.  The overhead of the

+virtual-array access protocol is very small when no swapping occurs.

+

+A virtual array can be specified to be "pre-zeroed"; when this flag is set,

+never-yet-written sections of the array are set to zero before being made

+available to the caller.  If this flag is not set, never-written sections

+of the array contain garbage.  (This feature exists primarily because the

+equivalent logic would otherwise be needed in jdcoefct.c for progressive

+JPEG mode; we may as well make it available for possible other uses.)

+

+The first write pass on a virtual array is required to occur in top-to-bottom

+order; read passes, as well as any write passes after the first one, may

+access the array in any order.  This restriction exists partly to simplify

+the virtual array control logic, and partly because some file systems may not

+support seeking beyond the current end-of-file in a temporary file.  The main

+implication of this restriction is that rearrangement of rows (such as

+converting top-to-bottom data order to bottom-to-top) must be handled while

+reading data out of the virtual array, not while putting it in.

+

+

+*** Memory manager internal structure ***

+

+To isolate system dependencies as much as possible, we have broken the

+memory manager into two parts.  There is a reasonably system-independent

+"front end" (jmemmgr.c) and a "back end" that contains only the code

+likely to change across systems.  All of the memory management methods

+outlined above are implemented by the front end.  The back end provides

+the following routines for use by the front end (none of these routines

+are known to the rest of the JPEG code):

+

+jpeg_mem_init, jpeg_mem_term    system-dependent initialization/shutdown

+

+jpeg_get_small, jpeg_free_small interface to malloc and free library routines

+                                (or their equivalents)

+

+jpeg_get_large, jpeg_free_large interface to FAR malloc/free in MSDOS machines;

+                                else usually the same as

+                                jpeg_get_small/jpeg_free_small

+

+jpeg_mem_available              estimate available memory

+

+jpeg_open_backing_store         create a backing-store object

+

+read_backing_store,             manipulate a backing-store object

+write_backing_store,

+close_backing_store

+

+On some systems there will be more than one type of backing-store object

+(specifically, in MS-DOS a backing store file might be an area of extended

+memory as well as a disk file).  jpeg_open_backing_store is responsible for

+choosing how to implement a given object.  The read/write/close routines

+are method pointers in the structure that describes a given object; this

+lets them be different for different object types.

+

+It may be necessary to ensure that backing store objects are explicitly

+released upon abnormal program termination.  For example, MS-DOS won't free

+extended memory by itself.  To support this, we will expect the main program

+or surrounding application to arrange to call self_destruct (typically via

+jpeg_destroy) upon abnormal termination.  This may require a SIGINT signal

+handler or equivalent.  We don't want to have the back end module install its

+own signal handler, because that would pre-empt the surrounding application's

+ability to control signal handling.

+

+The IJG distribution includes several memory manager back end implementations.

+Usually the same back end should be suitable for all applications on a given

+system, but it is possible for an application to supply its own back end at

+need.

+

+

+*** Implications of DNL marker ***

+

+Some JPEG files may use a DNL marker to postpone definition of the image

+height (this would be useful for a fax-like scanner's output, for instance).

+In these files the SOF marker claims the image height is 0, and you only

+find out the true image height at the end of the first scan.

+

+We could read these files as follows:

+1. Upon seeing zero image height, replace it by 65535 (the maximum allowed).

+2. When the DNL is found, update the image height in the global image

+   descriptor.

+This implies that control modules must avoid making copies of the image

+height, and must re-test for termination after each MCU row.  This would

+be easy enough to do.

+

+In cases where image-size data structures are allocated, this approach will

+result in very inefficient use of virtual memory or much-larger-than-necessary

+temporary files.  This seems acceptable for something that probably won't be a

+mainstream usage.  People might have to forgo use of memory-hogging options

+(such as two-pass color quantization or noninterleaved JPEG files) if they

+want efficient conversion of such files.  (One could improve efficiency by

+demanding a user-supplied upper bound for the height, less than 65536; in most

+cases it could be much less.)

+

+The standard also permits the SOF marker to overestimate the image height,

+with a DNL to give the true, smaller height at the end of the first scan.

+This would solve the space problems if the overestimate wasn't too great.

+However, it implies that you don't even know whether DNL will be used.

+

+This leads to a couple of very serious objections:

+1. Testing for a DNL marker must occur in the inner loop of the decompressor's

+   Huffman decoder; this implies a speed penalty whether the feature is used

+   or not.

+2. There is no way to hide the last-minute change in image height from an

+   application using the decoder.  Thus *every* application using the IJG

+   library would suffer a complexity penalty whether it cared about DNL or

+   not.

+We currently do not support DNL because of these problems.

+

+A different approach is to insist that DNL-using files be preprocessed by a

+separate program that reads ahead to the DNL, then goes back and fixes the SOF

+marker.  This is a much simpler solution and is probably far more efficient.

+Even if one wants piped input, buffering the first scan of the JPEG file needs

+a lot smaller temp file than is implied by the maximum-height method.  For

+this approach we'd simply treat DNL as a no-op in the decompressor (at most,

+check that it matches the SOF image height).

+

+We will not worry about making the compressor capable of outputting DNL.

+Something similar to the first scheme above could be applied if anyone ever

+wants to make that work.

+ * Lossless image transformation routines.  These routines work on DCT

+ * coefficient arrays and thus do not require any lossy decompression

+ * or recompression of the image.

+ * Thanks to Guido Vollbeding for the initial design and code of this feature,

+ * and to Ben Jackson for introducing the cropping feature.

+ *

+ * Horizontal flipping is done in-place, using a single top-to-bottom

+ * pass through the virtual source array.  It will thus be much the

+ * fastest option for images larger than main memory.

+ *

+ * The other routines require a set of destination virtual arrays, so they

+ * need twice as much memory as jpegtran normally does.  The destination

+ * arrays are always written in normal scan order (top to bottom) because

+ * the virtual array manager expects this.  The source arrays will be scanned

+ * in the corresponding order, which means multiple passes through the source

+ * arrays for most of the transforms.  That could result in much thrashing

+ * if the image is larger than main memory.

+ *

+ * If cropping or trimming is involved, the destination arrays may be smaller

+ * than the source arrays.  Note it is not possible to do horizontal flip

+ * in-place when a nonzero Y crop offset is specified, since we'd have to move

+ * data from one block row to another but the virtual array manager doesn't

+ * guarantee we can touch more than one row at a time.  So in that case,

+ * we have to use a separate destination array.

+ *

+ * Some notes about the operating environment of the individual transform

+ * routines:

+ * 1. Both the source and destination virtual arrays are allocated from the

+ *    source JPEG object, and therefore should be manipulated by calling the

+ *    source's memory manager.

+ * 2. The destination's component count should be used.  It may be smaller

+ *    than the source's when forcing to grayscale.

+ * 3. Likewise the destination's sampling factors should be used.  When

+ *    forcing to grayscale the destination's sampling factors will be all 1,

+ *    and we may as well take that as the effective iMCU size.

+ * 4. When "trim" is in effect, the destination's dimensions will be the

+ *    trimmed values but the source's will be untrimmed.

+ * 5. When "crop" is in effect, the destination's dimensions will be the

+ *    cropped values but the source's will be uncropped.  Each transform

+ *    routine is responsible for picking up source data starting at the

+ *    correct X and Y offset for the crop region.  (The X and Y offsets

+ *    passed to the transform routines are measured in iMCU blocks of the

+ *    destination.)

+ * 6. All the routines assume that the source and destination buffers are

+ *    padded out to a full iMCU boundary.  This is true, although for the

+ *    source buffer it is an undocumented property of jdcoefct.c.

+/*

+ * Although rotating and flipping data expressed as DCT coefficients is not

+ * hard, there is an asymmetry in the JPEG format specification for images

+ * whose dimensions aren't multiples of the iMCU size.  The right and bottom

+ * image edges are padded out to the next iMCU boundary with junk data; but

+ * no padding is possible at the top and left edges.  If we were to flip

+ * the whole image including the pad data, then pad garbage would become

+ * visible at the top and/or left, and real pixels would disappear into the

+ * pad margins --- perhaps permanently, since encoders & decoders may not

+ * bother to preserve DCT blocks that appear to be completely outside the

+ * nominal image area.  So, we have to exclude any partial iMCUs from the

+ * basic transformation.

+ *

+ * Transpose is the only transformation that can handle partial iMCUs at the

+ * right and bottom edges completely cleanly.  flip_h can flip partial iMCUs

+ * at the bottom, but leaves any partial iMCUs at the right edge untouched.

+ * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched.

+ * The other transforms are defined as combinations of these basic transforms

+ * and process edge blocks in a way that preserves the equivalence.

+ *

+ * The "trim" option causes untransformable partial iMCUs to be dropped;

+ * this is not strictly lossless, but it usually gives the best-looking

+ * result for odd-size images.  Note that when this option is active,

+ * the expected mathematical equivalences between the transforms may not hold.

+ * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim

+ * followed by -rot 180 -trim trims both edges.)

+ *

+ * We also offer a lossless-crop option, which discards data outside a given

+ * image region but losslessly preserves what is inside.  Like the rotate and

+ * flip transforms, lossless crop is restricted by the JPEG format: the upper

+ * left corner of the selected region must fall on an iMCU boundary.  If this

+ * does not hold for the given crop parameters, we silently move the upper left

+ * corner up and/or left to make it so, simultaneously increasing the region

+ * dimensions to keep the lower right crop corner unchanged.  (Thus, the

+ * output image covers at least the requested region, but may cover more.)

+ * The adjustment of the region dimensions may be optionally disabled.

+ *

+ * We also provide a lossless-resize option, which is kind of a lossless-crop

+ * operation in the DCT coefficient block domain - it discards higher-order

+ * coefficients and losslessly preserves lower-order coefficients of a

+ * sub-block.

+ *

+ * Rotate/flip transform, resize, and crop can be requested together in a

+ * single invocation.  The crop is applied last --- that is, the crop region

+ * is specified in terms of the destination image after transform/resize.

+ *

+ * We also offer a "force to grayscale" option, which simply discards the

+ * chrominance channels of a YCbCr image.  This is lossless in the sense that

+ * the luminance channel is preserved exactly.  It's not the same kind of

+ * thing as the rotate/flip transformations, but it's convenient to handle it

+ * as part of this package, mainly because the transformation routines have to

+ * be aware of the option to know how many components to work on.

+USAGE instructions for the Independent JPEG Group's JPEG software

+=================================================================

+

+This file describes usage of the JPEG conversion programs cjpeg and djpeg,

+as well as the utility programs jpegtran, rdjpgcom and wrjpgcom.  (See

+the other documentation files if you wish to use the JPEG library within

+your own programs.)

+

+If you are on a Unix machine you may prefer to read the Unix-style manual

+pages in files cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1.

+

+

+INTRODUCTION

+

+These programs implement JPEG image encoding, decoding, and transcoding.

+JPEG (pronounced "jay-peg") is a standardized compression method for

+full-color and gray-scale images.

+

+

+GENERAL USAGE

+

+We provide two programs, cjpeg to compress an image file into JPEG format,

+and djpeg to decompress a JPEG file back into a conventional image format.

+

+On Unix-like systems, you say:

+        cjpeg [switches] [imagefile] >jpegfile

+or

+        djpeg [switches] [jpegfile]  >imagefile

+The programs read the specified input file, or standard input if none is

+named.  They always write to standard output (with trace/error messages to

+standard error).  These conventions are handy for piping images between

+programs.

+

+On most non-Unix systems, you say:

+        cjpeg [switches] imagefile jpegfile

+or

+        djpeg [switches] jpegfile  imagefile

+i.e., both the input and output files are named on the command line.  This

+style is a little more foolproof, and it loses no functionality if you don't

+have pipes.  (You can get this style on Unix too, if you prefer, by defining

+TWO_FILE_COMMANDLINE when you compile the programs; see install.txt.)

+

+You can also say:

+        cjpeg [switches] -outfile jpegfile  imagefile

+or

+        djpeg [switches] -outfile imagefile  jpegfile

+This syntax works on all systems, so it is useful for scripts.

+

+The currently supported image file formats are: PPM (PBMPLUS color format),

+PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster Toolkit

+format).  (RLE is supported only if the URT library is available.)

+cjpeg recognizes the input image format automatically, with the exception

+of some Targa-format files.  You have to tell djpeg which format to generate.

+

+JPEG files are in the defacto standard JFIF file format.  There are other,

+less widely used JPEG-based file formats, but we don't support them.

+

+All switch names may be abbreviated; for example, -grayscale may be written

+-gray or -gr.  Most of the "basic" switches can be abbreviated to as little as

+one letter.  Upper and lower case are equivalent (-BMP is the same as -bmp).

+British spellings are also accepted (e.g., -greyscale), though for brevity

+these are not mentioned below.

+

+

+CJPEG DETAILS

+

+The basic command line switches for cjpeg are:

+

+        -quality N[,...]  Scale quantization tables to adjust image quality.

+                        Quality is 0 (worst) to 100 (best); default is 75.

+                        (See below for more info.)

+

+        -grayscale      Create monochrome JPEG file from color input.

+                        Be sure to use this switch when compressing a grayscale

+                        BMP file, because cjpeg isn't bright enough to notice

+                        whether a BMP file uses only shades of gray.  By

+                        saying -grayscale, you'll get a smaller JPEG file that

+                        takes less time to process.

+

+        -rgb            Create RGB JPEG file.

+                        Using this switch suppresses the conversion from RGB

+                        colorspace input to the default YCbCr JPEG colorspace.

+                        Use this switch in combination with the -block N

+                        switch (see below) for lossless JPEG coding.

+

+        -optimize       Perform optimization of entropy encoding parameters.

+                        Without this, default encoding parameters are used.

+                        -optimize usually makes the JPEG file a little smaller,

+                        but cjpeg runs somewhat slower and needs much more

+                        memory.  Image quality and speed of decompression are

+                        unaffected by -optimize.

+

+        -progressive    Create progressive JPEG file (see below).

+

+        -scale M/N      Scale the output image by a factor M/N.  Currently

+                        supported scale factors are M/N with all N from 1 to

+                        16, where M is the destination DCT size, which is 8 by

+                        default (see -block N switch below).

+

+        -targa          Input file is Targa format.  Targa files that contain

+                        an "identification" field will not be automatically

+                        recognized by cjpeg; for such files you must specify

+                        -targa to make cjpeg treat the input as Targa format.

+                        For most Targa files, you won't need this switch.

+

+The -quality switch lets you trade off compressed file size against quality of

+the reconstructed image: the higher the quality setting, the larger the JPEG

+file, and the closer the output image will be to the original input.  Normally

+you want to use the lowest quality setting (smallest file) that decompresses

+into something visually indistinguishable from the original image.  For this

+purpose the quality setting should be between 50 and 95; the default of 75 is

+often about right.  If you see defects at -quality 75, then go up 5 or 10

+counts at a time until you are happy with the output image.  (The optimal

+setting will vary from one image to another.)

+

+-quality 100 will generate a quantization table of all 1's, minimizing loss

+in the quantization step (but there is still information loss in subsampling,

+as well as roundoff error).  This setting is mainly of interest for

+experimental purposes.  Quality values above about 95 are NOT recommended for

+normal use; the compressed file size goes up dramatically for hardly any gain

+in output image quality.

+

+In the other direction, quality values below 50 will produce very small files

+of low image quality.  Settings around 5 to 10 might be useful in preparing an

+index of a large image library, for example.  Try -quality 2 (or so) for some

+amusing Cubist effects.  (Note: quality values below about 25 generate 2-byte

+quantization tables, which are considered optional in the JPEG standard.

+cjpeg emits a warning message when you give such a quality value, because some

+other JPEG programs may be unable to decode the resulting file.  Use -baseline

+if you need to ensure compatibility at low quality values.)

+

+The -quality option has been extended in IJG version 7 for support of separate

+quality settings for luminance and chrominance (or in general, for every

+provided quantization table slot).  This feature is useful for high-quality

+applications which cannot accept the damage of color data by coarse

+subsampling settings.  You can now easily reduce the color data amount more

+smoothly with finer control without separate subsampling.  The resulting file

+is fully compliant with standard JPEG decoders.

+Note that the -quality ratings refer to the quantization table slots, and that

+the last value is replicated if there are more q-table slots than parameters.

+The default q-table slots are 0 for luminance and 1 for chrominance with

+default tables as given in the JPEG standard.  This is compatible with the old

+behaviour in case that only one parameter is given, which is then used for

+both luminance and chrominance (slots 0 and 1).  More or custom quantization

+tables can be set with -qtables and assigned to components with -qslots

+parameter (see the "wizard" switches below).

+CAUTION: You must explicitly add -sample 1x1 for efficient separate color

+quality selection, since the default value used by library is 2x2!

+

+The -progressive switch creates a "progressive JPEG" file.  In this type of

+JPEG file, the data is stored in multiple scans of increasing quality.  If the

+file is being transmitted over a slow communications link, the decoder can use

+the first scan to display a low-quality image very quickly, and can then

+improve the display with each subsequent scan.  The final image is exactly

+equivalent to a standard JPEG file of the same quality setting, and the total

+file size is about the same --- often a little smaller.

+

+Switches for advanced users:

+

+        -arithmetic     Use arithmetic coding.  CAUTION: arithmetic coded JPEG

+                        is not yet widely implemented, so many decoders will

+                        be unable to view an arithmetic coded JPEG file at

+                        all.

+

+        -block N        Set DCT block size.  All N from 1 to 16 are possible.

+                        Default is 8 (baseline format).

+                        Larger values produce higher compression,

+                        smaller values produce higher quality

+                        (exact DCT stage possible with 1 or 2; with the

+                        default quality of 75 and default Luminance qtable

+                        the DCT+Quantization stage is lossless for N=1).

+                        CAUTION: An implementation of the JPEG SmartScale

+                        extension is required for this feature.  SmartScale

+                        enabled JPEG is not yet widely implemented, so many

+                        decoders will be unable to view a SmartScale extended

+                        JPEG file at all.

+

+        -dct int        Use integer DCT method (default).

+        -dct fast       Use fast integer DCT (less accurate).

+        -dct float      Use floating-point DCT method.

+                        The float method is very slightly more accurate than

+                        the int method, but is much slower unless your machine

+                        has very fast floating-point hardware.  Also note that

+                        results of the floating-point method may vary slightly

+                        across machines, while the integer methods should give

+                        the same results everywhere.  The fast integer method

+                        is much less accurate than the other two.

+

+        -nosmooth       Don't use high-quality downsampling.

+

+        -restart N      Emit a JPEG restart marker every N MCU rows, or every

+                        N MCU blocks if "B" is attached to the number.

+                        -restart 0 (the default) means no restart markers.

+

+        -smooth N       Smooth the input image to eliminate dithering noise.

+                        N, ranging from 1 to 100, indicates the strength of

+                        smoothing.  0 (the default) means no smoothing.

+

+        -maxmemory N    Set limit for amount of memory to use in processing

+                        large images.  Value is in thousands of bytes, or

+                        millions of bytes if "M" is attached to the number.

+                        For example, -max 4m selects 4000000 bytes.  If more

+                        space is needed, temporary files will be used.

+

+        -verbose        Enable debug printout.  More -v's give more printout.

+        or  -debug      Also, version information is printed at startup.

+

+The -restart option inserts extra markers that allow a JPEG decoder to

+resynchronize after a transmission error.  Without restart markers, any damage

+to a compressed file will usually ruin the image from the point of the error

+to the end of the image; with restart markers, the damage is usually confined

+to the portion of the image up to the next restart marker.  Of course, the

+restart markers occupy extra space.  We recommend -restart 1 for images that

+will be transmitted across unreliable networks such as Usenet.

+

+The -smooth option filters the input to eliminate fine-scale noise.  This is

+often useful when converting dithered images to JPEG: a moderate smoothing

+factor of 10 to 50 gets rid of dithering patterns in the input file, resulting

+in a smaller JPEG file and a better-looking image.  Too large a smoothing

+factor will visibly blur the image, however.

+

+Switches for wizards:

+

+        -baseline       Force baseline-compatible quantization tables to be

+                        generated.  This clamps quantization values to 8 bits

+                        even at low quality settings.  (This switch is poorly

+                        named, since it does not ensure that the output is

+                        actually baseline JPEG.  For example, you can use

+                        -baseline and -progressive together.)

+

+        -qtables file   Use the quantization tables given in the specified

+                        text file.

+

+        -qslots N[,...] Select which quantization table to use for each color

+                        component.

+

+        -sample HxV[,...]  Set JPEG sampling factors for each color component.

+

+        -scans file     Use the scan script given in the specified text file.

+

+The "wizard" switches are intended for experimentation with JPEG.  If you

+don't know what you are doing, DON'T USE THEM.  These switches are documented

+further in the file wizard.txt.

+

+

+DJPEG DETAILS

+

+The basic command line switches for djpeg are:

+

+        -colors N       Reduce image to at most N colors.  This reduces the

+        or -quantize N  number of colors used in the output image, so that it

+                        can be displayed on a colormapped display or stored in

+                        a colormapped file format.  For example, if you have

+                        an 8-bit display, you'd need to reduce to 256 or fewer

+                        colors.  (-colors is the recommended name, -quantize

+                        is provided only for backwards compatibility.)

+

+        -fast           Select recommended processing options for fast, low

+                        quality output.  (The default options are chosen for

+                        highest quality output.)  Currently, this is equivalent

+                        to "-dct fast -nosmooth -onepass -dither ordered".

+

+        -grayscale      Force gray-scale output even if JPEG file is color.

+                        Useful for viewing on monochrome displays; also,

+                        djpeg runs noticeably faster in this mode.

+

+        -scale M/N      Scale the output image by a factor M/N.  Currently

+                        supported scale factors are M/N with all M from 1 to

+                        16, where N is the source DCT size, which is 8 for

+                        baseline JPEG.  If the /N part is omitted, then M

+                        specifies the DCT scaled size to be applied on the

+                        given input.  For baseline JPEG this is equivalent to

+                        M/8 scaling, since the source DCT size for baseline

+                        JPEG is 8.  Scaling is handy if the image is larger

+                        than your screen; also, djpeg runs much faster when

+                        scaling down the output.

+

+        -bmp            Select BMP output format (Windows flavor).  8-bit

+                        colormapped format is emitted if -colors or -grayscale

+                        is specified, or if the JPEG file is gray-scale;

+                        otherwise, 24-bit full-color format is emitted.

+

+        -gif            Select GIF output format.  Since GIF does not support

+                        more than 256 colors, -colors 256 is assumed (unless

+                        you specify a smaller number of colors).  If you

+                        specify -fast, the default number of colors is 216.

+

+        -os2            Select BMP output format (OS/2 1.x flavor).  8-bit

+                        colormapped format is emitted if -colors or -grayscale

+                        is specified, or if the JPEG file is gray-scale;

+                        otherwise, 24-bit full-color format is emitted.

+

+        -pnm            Select PBMPLUS (PPM/PGM) output format (this is the

+                        default format).  PGM is emitted if the JPEG file is

+                        gray-scale or if -grayscale is specified; otherwise

+                        PPM is emitted.

+

+        -rle            Select RLE output format.  (Requires URT library.)

+

+        -targa          Select Targa output format.  Gray-scale format is

+                        emitted if the JPEG file is gray-scale or if

+                        -grayscale is specified; otherwise, colormapped format

+                        is emitted if -colors is specified; otherwise, 24-bit

+                        full-color format is emitted.

+

+Switches for advanced users:

+

+        -dct int        Use integer DCT method (default).

+        -dct fast       Use fast integer DCT (less accurate).

+        -dct float      Use floating-point DCT method.

+                        The float method is very slightly more accurate than

+                        the int method, but is much slower unless your machine

+                        has very fast floating-point hardware.  Also note that

+                        results of the floating-point method may vary slightly

+                        across machines, while the integer methods should give

+                        the same results everywhere.  The fast integer method

+                        is much less accurate than the other two.

+

+        -dither fs      Use Floyd-Steinberg dithering in color quantization.

+        -dither ordered Use ordered dithering in color quantization.

+        -dither none    Do not use dithering in color quantization.

+                        By default, Floyd-Steinberg dithering is applied when

+                        quantizing colors; this is slow but usually produces

+                        the best results.  Ordered dither is a compromise

+                        between speed and quality; no dithering is fast but

+                        usually looks awful.  Note that these switches have

+                        no effect unless color quantization is being done.

+                        Ordered dither is only available in -onepass mode.

+

+        -map FILE       Quantize to the colors used in the specified image

+                        file.  This is useful for producing multiple files

+                        with identical color maps, or for forcing a predefined

+                        set of colors to be used.  The FILE must be a GIF

+                        or PPM file.  This option overrides -colors and

+                        -onepass.

+

+        -nosmooth       Don't use high-quality upsampling.

+

+        -onepass        Use one-pass instead of two-pass color quantization.

+                        The one-pass method is faster and needs less memory,

+                        but it produces a lower-quality image.  -onepass is

+                        ignored unless you also say -colors N.  Also,

+                        the one-pass method is always used for gray-scale

+                        output (the two-pass method is no improvement then).

+

+        -maxmemory N    Set limit for amount of memory to use in processing

+                        large images.  Value is in thousands of bytes, or

+                        millions of bytes if "M" is attached to the number.

+                        For example, -max 4m selects 4000000 bytes.  If more

+                        space is needed, temporary files will be used.

+

+        -verbose        Enable debug printout.  More -v's give more printout.

+        or  -debug      Also, version information is printed at startup.

+

+

+HINTS FOR CJPEG

+

+Color GIF files are not the ideal input for JPEG; JPEG is really intended for

+compressing full-color (24-bit) images.  In particular, don't try to convert

+cartoons, line drawings, and other images that have only a few distinct

+colors.  GIF works great on these, JPEG does not.  If you want to convert a

+GIF to JPEG, you should experiment with cjpeg's -quality and -smooth options

+to get a satisfactory conversion.  -smooth 10 or so is often helpful.

+

+Avoid running an image through a series of JPEG compression/decompression

+cycles.  Image quality loss will accumulate; after ten or so cycles the image

+may be noticeably worse than it was after one cycle.  It's best to use a

+lossless format while manipulating an image, then convert to JPEG format when

+you are ready to file the image away.

+

+The -optimize option to cjpeg is worth using when you are making a "final"

+version for posting or archiving.  It's also a win when you are using low

+quality settings to make very small JPEG files; the percentage improvement

+is often a lot more than it is on larger files.  (At present, -optimize

+mode is always selected when generating progressive JPEG files.)

+

+GIF input files are no longer supported, to avoid the Unisys LZW patent.

+(Conversion of GIF files to JPEG is usually a bad idea anyway.)

+

+

+HINTS FOR DJPEG

+

+To get a quick preview of an image, use the -grayscale and/or -scale switches.

+"-grayscale -scale 1/8" is the fastest case.

+

+Several options are available that trade off image quality to gain speed.

+"-fast" turns on the recommended settings.

+

+"-dct fast" and/or "-nosmooth" gain speed at a small sacrifice in quality.

+When producing a color-quantized image, "-onepass -dither ordered" is fast but

+much lower quality than the default behavior.  "-dither none" may give

+acceptable results in two-pass mode, but is seldom tolerable in one-pass mode.

+

+If you are fortunate enough to have very fast floating point hardware,

+"-dct float" may be even faster than "-dct fast".  But on most machines

+"-dct float" is slower than "-dct int"; in this case it is not worth using,

+because its theoretical accuracy advantage is too small to be significant

+in practice.

+

+Two-pass color quantization requires a good deal of memory; on MS-DOS machines

+it may run out of memory even with -maxmemory 0.  In that case you can still

+decompress, with some loss of image quality, by specifying -onepass for

+one-pass quantization.

+

+To avoid the Unisys LZW patent, djpeg produces uncompressed GIF files.  These

+are larger than they should be, but are readable by standard GIF decoders.

+

+

+HINTS FOR BOTH PROGRAMS

+

+If more space is needed than will fit in the available main memory (as

+determined by -maxmemory), temporary files will be used.  (MS-DOS versions

+will try to get extended or expanded memory first.)  The temporary files are

+often rather large: in typical cases they occupy three bytes per pixel, for

+example 3*800*600 = 1.44Mb for an 800x600 image.  If you don't have enough

+free disk space, leave out -progressive and -optimize (for cjpeg) or specify

+-onepass (for djpeg).

+

+On MS-DOS, the temporary files are created in the directory named by the TMP

+or TEMP environment variable, or in the current directory if neither of those

+exist.  Amiga implementations put the temp files in the directory named by

+JPEGTMP:, so be sure to assign JPEGTMP: to a disk partition with adequate free

+space.

+

+The default memory usage limit (-maxmemory) is set when the software is

+compiled.  If you get an "insufficient memory" error, try specifying a smaller

+-maxmemory value, even -maxmemory 0 to use the absolute minimum space.  You

+may want to recompile with a smaller default value if this happens often.

+

+On machines that have "environment" variables, you can define the environment

+variable JPEGMEM to set the default memory limit.  The value is specified as

+described for the -maxmemory switch.  JPEGMEM overrides the default value

+specified when the program was compiled, and itself is overridden by an

+explicit -maxmemory switch.

+

+On MS-DOS machines, -maxmemory is the amount of main (conventional) memory to

+use.  (Extended or expanded memory is also used if available.)  Most

+DOS-specific versions of this software do their own memory space estimation

+and do not need you to specify -maxmemory.

+

+

+JPEGTRAN

+

+jpegtran performs various useful transformations of JPEG files.

+It can translate the coded representation from one variant of JPEG to another,

+for example from baseline JPEG to progressive JPEG or vice versa.  It can also

+perform some rearrangements of the image data, for example turning an image

+from landscape to portrait format by rotation.

+

+jpegtran works by rearranging the compressed data (DCT coefficients), without

+ever fully decoding the image.  Therefore, its transformations are lossless:

+there is no image degradation at all, which would not be true if you used

+djpeg followed by cjpeg to accomplish the same conversion.  But by the same

+token, jpegtran cannot perform lossy operations such as changing the image

+quality.

+

+jpegtran uses a command line syntax similar to cjpeg or djpeg.

+On Unix-like systems, you say:

+        jpegtran [switches] [inputfile] >outputfile

+On most non-Unix systems, you say:

+        jpegtran [switches] inputfile outputfile

+where both the input and output files are JPEG files.

+

+To specify the coded JPEG representation used in the output file,

+jpegtran accepts a subset of the switches recognized by cjpeg:

+        -optimize       Perform optimization of entropy encoding parameters.

+        -progressive    Create progressive JPEG file.

+        -arithmetic     Use arithmetic coding.

+        -restart N      Emit a JPEG restart marker every N MCU rows, or every

+                        N MCU blocks if "B" is attached to the number.

+        -scans file     Use the scan script given in the specified text file.

+See the previous discussion of cjpeg for more details about these switches.

+If you specify none of these switches, you get a plain baseline-JPEG output

+file.  The quality setting and so forth are determined by the input file.

+

+The image can be losslessly transformed by giving one of these switches:

+        -flip horizontal        Mirror image horizontally (left-right).

+        -flip vertical          Mirror image vertically (top-bottom).

+        -rotate 90              Rotate image 90 degrees clockwise.

+        -rotate 180             Rotate image 180 degrees.

+        -rotate 270             Rotate image 270 degrees clockwise (or 90 ccw).

+        -transpose              Transpose image (across UL-to-LR axis).

+        -transverse             Transverse transpose (across UR-to-LL axis).

+

+The transpose transformation has no restrictions regarding image dimensions.

+The other transformations operate rather oddly if the image dimensions are not

+a multiple of the iMCU size (usually 8 or 16 pixels), because they can only

+transform complete blocks of DCT coefficient data in the desired way.

+

+jpegtran's default behavior when transforming an odd-size image is designed

+to preserve exact reversibility and mathematical consistency of the

+transformation set.  As stated, transpose is able to flip the entire image

+area.  Horizontal mirroring leaves any partial iMCU column at the right edge

+untouched, but is able to flip all rows of the image.  Similarly, vertical

+mirroring leaves any partial iMCU row at the bottom edge untouched, but is

+able to flip all columns.  The other transforms can be built up as sequences

+of transpose and flip operations; for consistency, their actions on edge

+pixels are defined to be the same as the end result of the corresponding

+transpose-and-flip sequence.

+

+For practical use, you may prefer to discard any untransformable edge pixels

+rather than having a strange-looking strip along the right and/or bottom edges

+of a transformed image.  To do this, add the -trim switch:

+        -trim           Drop non-transformable edge blocks.

+Obviously, a transformation with -trim is not reversible, so strictly speaking

+jpegtran with this switch is not lossless.  Also, the expected mathematical

+equivalences between the transformations no longer hold.  For example,

+"-rot 270 -trim" trims only the bottom edge, but "-rot 90 -trim" followed by

+"-rot 180 -trim" trims both edges.

+

+If you are only interested in perfect transformation, add the -perfect switch:

+        -perfect        Fails with an error if the transformation is not

+                        perfect.

+For example you may want to do

+  jpegtran -rot 90 -perfect foo.jpg || djpeg foo.jpg | pnmflip -r90 | cjpeg

+to do a perfect rotation if available or an approximated one if not.

+

+We also offer a lossless-crop option, which discards data outside a given

+image region but losslessly preserves what is inside.  Like the rotate and

+flip transforms, lossless crop is restricted by the current JPEG format: the

+upper left corner of the selected region must fall on an iMCU boundary.  If

+this does not hold for the given crop parameters, we silently move the upper

+left corner up and/or left to make it so, simultaneously increasing the region

+dimensions to keep the lower right crop corner unchanged.  (Thus, the output

+image covers at least the requested region, but may cover more.)

+

+The image can be losslessly cropped by giving the switch:

+        -crop WxH+X+Y   Crop to a rectangular subarea of width W, height H

+                        starting at point X,Y.

+

+Other not-strictly-lossless transformation switches are:

+

+        -grayscale      Force grayscale output.

+This option discards the chrominance channels if the input image is YCbCr

+(ie, a standard color JPEG), resulting in a grayscale JPEG file.  The

+luminance channel is preserved exactly, so this is a better method of reducing

+to grayscale than decompression, conversion, and recompression.  This switch

+is particularly handy for fixing a monochrome picture that was mistakenly

+encoded as a color JPEG.  (In such a case, the space savings from getting rid

+of the near-empty chroma channels won't be large; but the decoding time for

+a grayscale JPEG is substantially less than that for a color JPEG.)

+

+        -scale M/N      Scale the output image by a factor M/N.

+Currently supported scale factors are M/N with all M from 1 to 16, where N is

+the source DCT size, which is 8 for baseline JPEG.  If the /N part is omitted,

+then M specifies the DCT scaled size to be applied on the given input.  For

+baseline JPEG this is equivalent to M/8 scaling, since the source DCT size

+for baseline JPEG is 8.  CAUTION: An implementation of the JPEG SmartScale

+extension is required for this feature.  SmartScale enabled JPEG is not yet

+widely implemented, so many decoders will be unable to view a SmartScale

+extended JPEG file at all.

+

+jpegtran also recognizes these switches that control what to do with "extra"

+markers, such as comment blocks:

+        -copy none      Copy no extra markers from source file.  This setting

+                        suppresses all comments and other excess baggage

+                        present in the source file.

+        -copy comments  Copy only comment markers.  This setting copies

+                        comments from the source file, but discards

+                        any other inessential (for image display) data.

+        -copy all       Copy all extra markers.  This setting preserves

+                        miscellaneous markers found in the source file, such

+                        as JFIF thumbnails, Exif data, and Photoshop settings.

+                        In some files these extra markers can be sizable.

+The default behavior is -copy comments.  (Note: in IJG releases v6 and v6a,

+jpegtran always did the equivalent of -copy none.)

+

+Additional switches recognized by jpegtran are:

+        -outfile filename

+        -maxmemory N

+        -verbose

+        -debug

+These work the same as in cjpeg or djpeg.

+

+

+THE COMMENT UTILITIES

+

+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.

+Although the standard doesn't actually define what COM blocks are for, they

+are widely used to hold user-supplied text strings.  This lets you add

+annotations, titles, index terms, etc to your JPEG files, and later retrieve

+them as text.  COM blocks do not interfere with the image stored in the JPEG

+file.  The maximum size of a COM block is 64K, but you can have as many of

+them as you like in one JPEG file.

+

+We provide two utility programs to display COM block contents and add COM

+blocks to a JPEG file.

+

+rdjpgcom searches a JPEG file and prints the contents of any COM blocks on

+standard output.  The command line syntax is

+        rdjpgcom [-raw] [-verbose] [inputfilename]

+The switch "-raw" (or just "-r") causes rdjpgcom to also output non-printable

+characters in comments, which are normally escaped for security reasons.

+The switch "-verbose" (or just "-v") causes rdjpgcom to also display the JPEG

+image dimensions.  If you omit the input file name from the command line,

+the JPEG file is read from standard input.  (This may not work on some

+operating systems, if binary data can't be read from stdin.)

+

+wrjpgcom adds a COM block, containing text you provide, to a JPEG file.

+Ordinarily, the COM block is added after any existing COM blocks, but you

+can delete the old COM blocks if you wish.  wrjpgcom produces a new JPEG

+file; it does not modify the input file.  DO NOT try to overwrite the input

+file by directing wrjpgcom's output back into it; on most systems this will

+just destroy your file.

+

+The command line syntax for wrjpgcom is similar to cjpeg's.  On Unix-like

+systems, it is

+        wrjpgcom [switches] [inputfilename]

+The output file is written to standard output.  The input file comes from

+the named file, or from standard input if no input file is named.

+

+On most non-Unix systems, the syntax is

+        wrjpgcom [switches] inputfilename outputfilename

+where both input and output file names must be given explicitly.

+

+wrjpgcom understands three switches:

+        -replace                 Delete any existing COM blocks from the file.

+        -comment "Comment text"  Supply new COM text on command line.

+        -cfile name              Read text for new COM block from named file.

+(Switch names can be abbreviated.)  If you have only one line of comment text

+to add, you can provide it on the command line with -comment.  The comment

+text must be surrounded with quotes so that it is treated as a single

+argument.  Longer comments can be read from a text file.

+

+If you give neither -comment nor -cfile, then wrjpgcom will read the comment

+text from standard input.  (In this case an input image file name MUST be

+supplied, so that the source JPEG file comes from somewhere else.)  You can

+enter multiple lines, up to 64KB worth.  Type an end-of-file indicator

+(usually control-D or control-Z) to terminate the comment text entry.

+

+wrjpgcom will not add a COM block if the provided comment string is empty.

+Therefore -replace -comment "" can be used to delete all COM blocks from a

+file.

+

+These utility programs do not depend on the IJG JPEG library.  In

+particular, the source code for rdjpgcom is intended as an illustration of

+the minimum amount of code required to parse a JPEG file header correctly.

+Advanced usage instructions for the Independent JPEG Group's JPEG software

+==========================================================================

+

+This file describes cjpeg's "switches for wizards".

+

+The "wizard" switches are intended for experimentation with JPEG by persons

+who are reasonably knowledgeable about the JPEG standard.  If you don't know

+what you are doing, DON'T USE THESE SWITCHES.  You'll likely produce files

+with worse image quality and/or poorer compression than you'd get from the

+default settings.  Furthermore, these switches must be used with caution

+when making files intended for general use, because not all JPEG decoders

+will support unusual JPEG parameter settings.

+

+

+Quantization Table Adjustment

+-----------------------------

+

+Ordinarily, cjpeg starts with a default set of tables (the same ones given

+as examples in the JPEG standard) and scales them up or down according to

+the -quality setting.  The details of the scaling algorithm can be found in

+jcparam.c.  At very low quality settings, some quantization table entries

+can get scaled up to values exceeding 255.  Although 2-byte quantization

+values are supported by the IJG software, this feature is not in baseline

+JPEG and is not supported by all implementations.  If you need to ensure

+wide compatibility of low-quality files, you can constrain the scaled

+quantization values to no more than 255 by giving the -baseline switch.

+Note that use of -baseline will result in poorer quality for the same file

+size, since more bits than necessary are expended on higher AC coefficients.

+

+You can substitute a different set of quantization values by using the

+-qtables switch:

+

+        -qtables file   Use the quantization tables given in the named file.

+

+The specified file should be a text file containing decimal quantization

+values.  The file should contain one to four tables, each of 64 elements.

+The tables are implicitly numbered 0,1,etc. in order of appearance.  Table

+entries appear in normal array order (NOT in the zigzag order in which they

+will be stored in the JPEG file).

+

+Quantization table files are free format, in that arbitrary whitespace can

+appear between numbers.  Also, comments can be included: a comment starts

+with '#' and extends to the end of the line.  Here is an example file that

+duplicates the default quantization tables:

+

+        # Quantization tables given in JPEG spec, section K.1

+

+        # This is table 0 (the luminance table):

+          16  11  10  16  24  40  51  61

+          12  12  14  19  26  58  60  55

+          14  13  16  24  40  57  69  56

+          14  17  22  29  51  87  80  62

+          18  22  37  56  68 109 103  77

+          24  35  55  64  81 104 113  92

+          49  64  78  87 103 121 120 101

+          72  92  95  98 112 100 103  99

+

+        # This is table 1 (the chrominance table):

+          17  18  24  47  99  99  99  99

+          18  21  26  66  99  99  99  99

+          24  26  56  99  99  99  99  99

+          47  66  99  99  99  99  99  99

+          99  99  99  99  99  99  99  99

+          99  99  99  99  99  99  99  99

+          99  99  99  99  99  99  99  99

+          99  99  99  99  99  99  99  99

+

+If the -qtables switch is used without -quality, then the specified tables

+are used exactly as-is.  If both -qtables and -quality are used, then the

+tables taken from the file are scaled in the same fashion that the default

+tables would be scaled for that quality setting.  If -baseline appears, then

+the quantization values are constrained to the range 1-255.

+

+By default, cjpeg will use quantization table 0 for luminance components and

+table 1 for chrominance components.  To override this choice, use the -qslots

+switch:

+

+        -qslots N[,...]         Select which quantization table to use for

+                                each color component.

+

+The -qslots switch specifies a quantization table number for each color

+component, in the order in which the components appear in the JPEG SOF marker.

+For example, to create a separate table for each of Y,Cb,Cr, you could

+provide a -qtables file that defines three quantization tables and say

+"-qslots 0,1,2".  If -qslots gives fewer table numbers than there are color

+components, then the last table number is repeated as necessary.

+

+

+Sampling Factor Adjustment

+--------------------------

+

+By default, cjpeg uses 2:1 horizontal and vertical downsampling when

+compressing YCbCr data, and no downsampling for all other color spaces.

+You can override this default with the -sample switch:

+

+        -sample HxV[,...]       Set JPEG sampling factors for each color

+                                component.

+

+The -sample switch specifies the JPEG sampling factors for each color

+component, in the order in which they appear in the JPEG SOF marker.

+If you specify fewer HxV pairs than there are components, the remaining

+components are set to 1x1 sampling.  For example, the default YCbCr setting

+is equivalent to "-sample 2x2,1x1,1x1", which can be abbreviated to

+"-sample 2x2".

+

+There are still some JPEG decoders in existence that support only 2x1

+sampling (also called 4:2:2 sampling).  Compatibility with such decoders can

+be achieved by specifying "-sample 2x1".  This is not recommended unless

+really necessary, since it increases file size and encoding/decoding time

+with very little quality gain.

+

+

+Multiple Scan / Progression Control

+-----------------------------------

+

+By default, cjpeg emits a single-scan sequential JPEG file.  The

+-progressive switch generates a progressive JPEG file using a default series

+of progression parameters.  You can create multiple-scan sequential JPEG

+files or progressive JPEG files with custom progression parameters by using

+the -scans switch:

+

+        -scans file     Use the scan sequence given in the named file.

+

+The specified file should be a text file containing a "scan script".

+The script specifies the contents and ordering of the scans to be emitted.

+Each entry in the script defines one scan.  A scan definition specifies

+the components to be included in the scan, and for progressive JPEG it also

+specifies the progression parameters Ss,Se,Ah,Al for the scan.  Scan

+definitions are separated by semicolons (';').  A semicolon after the last

+scan definition is optional.

+

+Each scan definition contains one to four component indexes, optionally

+followed by a colon (':') and the four progressive-JPEG parameters.  The

+component indexes denote which color component(s) are to be transmitted in

+the scan.  Components are numbered in the order in which they appear in the

+JPEG SOF marker, with the first component being numbered 0.  (Note that these

+indexes are not the "component ID" codes assigned to the components, just

+positional indexes.)

+

+The progression parameters for each scan are:

+        Ss      Zigzag index of first coefficient included in scan

+        Se      Zigzag index of last coefficient included in scan

+        Ah      Zero for first scan of a coefficient, else Al of prior scan

+        Al      Successive approximation low bit position for scan

+If the progression parameters are omitted, the values 0,63,0,0 are used,

+producing a sequential JPEG file.  cjpeg automatically determines whether

+the script represents a progressive or sequential file, by observing whether

+Ss and Se values other than 0 and 63 appear.  (The -progressive switch is

+not needed to specify this; in fact, it is ignored when -scans appears.)

+The scan script must meet the JPEG restrictions on progression sequences.

+(cjpeg checks that the spec's requirements are obeyed.)

+

+Scan script files are free format, in that arbitrary whitespace can appear

+between numbers and around punctuation.  Also, comments can be included: a

+comment starts with '#' and extends to the end of the line.  For additional

+legibility, commas or dashes can be placed between values.  (Actually, any

+single punctuation character other than ':' or ';' can be inserted.)  For

+example, the following two scan definitions are equivalent:

+        0 1 2: 0 63 0 0;

+        0,1,2 : 0-63, 0,0 ;

+

+Here is an example of a scan script that generates a partially interleaved

+sequential JPEG file:

+

+        0;                      # Y only in first scan

+        1 2;                    # Cb and Cr in second scan

+

+Here is an example of a progressive scan script using only spectral selection

+(no successive approximation):

+

+        # Interleaved DC scan for Y,Cb,Cr:

+        0,1,2: 0-0,   0, 0 ;

+        # AC scans:

+        0:     1-2,   0, 0 ;    # First two Y AC coefficients

+        0:     3-5,   0, 0 ;    # Three more

+        1:     1-63,  0, 0 ;    # All AC coefficients for Cb

+        2:     1-63,  0, 0 ;    # All AC coefficients for Cr

+        0:     6-9,   0, 0 ;    # More Y coefficients

+        0:     10-63, 0, 0 ;    # Remaining Y coefficients

+

+Here is an example of a successive-approximation script.  This is equivalent

+to the default script used by "cjpeg -progressive" for YCbCr images:

+

+        # Initial DC scan for Y,Cb,Cr (lowest bit not sent)

+        0,1,2: 0-0,   0, 1 ;

+        # First AC scan: send first 5 Y AC coefficients, minus 2 lowest bits:

+        0:     1-5,   0, 2 ;

+        # Send all Cr,Cb AC coefficients, minus lowest bit:

+        # (chroma data is usually too small to be worth subdividing further;

+        #  but note we send Cr first since eye is least sensitive to Cb)

+        2:     1-63,  0, 1 ;

+        1:     1-63,  0, 1 ;

+        # Send remaining Y AC coefficients, minus 2 lowest bits:

+        0:     6-63,  0, 2 ;

+        # Send next-to-lowest bit of all Y AC coefficients:

+        0:     1-63,  2, 1 ;

+        # At this point we've sent all but the lowest bit of all coefficients.

+        # Send lowest bit of DC coefficients

+        0,1,2: 0-0,   1, 0 ;

+        # Send lowest bit of AC coefficients

+        2:     1-63,  1, 0 ;

+        1:     1-63,  1, 0 ;

+        # Y AC lowest bit scan is last; it's usually the largest scan

+        0:     1-63,  1, 0 ;

+

+It may be worth pointing out that this script is tuned for quality settings

+of around 50 to 75.  For lower quality settings, you'd probably want to use

+a script with fewer stages of successive approximation (otherwise the

+initial scans will be really bad).  For higher quality settings, you might

+want to use more stages of successive approximation (so that the initial

+scans are not too large).

+ * Thus, all the symbols in the output file will have the same bit width.

+ * Note that emitting the Clear codes at the right times is a mere matter of

+ * counting output symbols and is in no way dependent on the LZW patent.

+ *

+ * With a small basic pixel width (low color count), Clear codes will be

+ * needed very frequently, causing the file to expand even more.  So this

+ * simplistic approach wouldn't work too well on bilevel images, for example.

+ * But for output of JPEG conversions the pixel width will usually be 8 bits

+.TH WRJPGCOM 1 "15 June 1995"

+.SH NAME

+wrjpgcom \- insert text comments into a JPEG file

+.SH SYNOPSIS

+.B wrjpgcom

+[

+.B \-replace

+]

+[

+.BI \-comment " text"

+]

+[

+.BI \-cfile " name"

+]

+[

+.I filename

+]

+.LP

+.SH DESCRIPTION

+.LP

+.B wrjpgcom

+reads the named JPEG/JFIF file, or the standard input if no file is named,

+and generates a new JPEG/JFIF file on standard output.  A comment block is

+added to the file.

+.PP

+The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file.

+Although the standard doesn't actually define what COM blocks are for, they

+are widely used to hold user-supplied text strings.  This lets you add

+annotations, titles, index terms, etc to your JPEG files, and later retrieve

+them as text.  COM blocks do not interfere with the image stored in the JPEG

+file.  The maximum size of a COM block is 64K, but you can have as many of

+them as you like in one JPEG file.

+.PP

+.B wrjpgcom

+adds a COM block, containing text you provide, to a JPEG file.

+Ordinarily, the COM block is added after any existing COM blocks; but you

+can delete the old COM blocks if you wish.

+.SH OPTIONS

+Switch names may be abbreviated, and are not case sensitive.

+.TP

+.B \-replace

+Delete any existing COM blocks from the file.

+.TP

+.BI \-comment " text"

+Supply text for new COM block on command line.

+.TP

+.BI \-cfile " name"

+Read text for new COM block from named file.

+.PP

+If you have only one line of comment text to add, you can provide it on the

+command line with

+.BR \-comment .

+The comment text must be surrounded with quotes so that it is treated as a

+single argument.  Longer comments can be read from a text file.

+.PP

+If you give neither

+.B \-comment

+nor

+.BR \-cfile ,

+then

+.B wrjpgcom

+will read the comment text from standard input.  (In this case an input image

+file name MUST be supplied, so that the source JPEG file comes from somewhere

+else.)  You can enter multiple lines, up to 64KB worth.  Type an end-of-file

+indicator (usually control-D) to terminate the comment text entry.

+.PP

+.B wrjpgcom

+will not add a COM block if the provided comment string is empty.  Therefore

+\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file.

+.SH EXAMPLES

+.LP

+Add a short comment to in.jpg, producing out.jpg:

+.IP

+.B wrjpgcom \-c

+\fI"View of my back yard" in.jpg

+.B >

+.I out.jpg

+.PP

+Attach a long comment previously stored in comment.txt:

+.IP

+.B wrjpgcom

+.I in.jpg

+.B <

+.I comment.txt

+.B >

+.I out.jpg

+.PP

+or equivalently

+.IP

+.B wrjpgcom

+.B -cfile

+.I comment.txt

+.B <

+.I in.jpg

+.B >

+.I out.jpg
