-

-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."

-

-

-REFERENCES

-==========

-

-We recommend reading one or more of these references before trying to

-understand the innards of the JPEG software.

-

-The best short technical introduction to the JPEG compression algorithm is

-        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.

+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...
