+

+

+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.
