The Independent JPEG Group's JPEG software ========================================== README for release 6b of 27-Mar-1998 ==================================== This distribution contains the sixth public release of the Independent JPEG Group's free JPEG software. You are welcome to redistribute this software and to use it for any purpose, subject to the conditions under LEGAL ISSUES, below.Serious users of this software (particularly those incorporating it into larger programs) should contact IJG at to be added to our electronic mailing list. Mailing list members are notified of updates and have a chance to participate in technical discussions, etc. This software is the work of Tom Lane, Philip Gladstone, Jim Boucher, Lee Crocker, Julian Minguillon, Luis Ortiz,George Phillips, Davide Rossi, Guido Vollbeding, Ge' Weijers, and other members of the Independent JPEG Group. IJG is not affiliated with the official ISO JPEG standards committee. DOCUMENTATION ROADMAP ===================== This file contains the following sections: OVERVIEW LEGAL ISSUES REFERENCES ARCHIVE LOCATIONS RELATED SOFTWARE FILE FORMAT WARS TO DO General description of JPEG and the IJGsoftware. Copyright, lack of warranty, terms of distribution. Where to learn more about JPEG. Where to find newer versions of this software. Other stuff you should get. Software *not* to get. Plans for future IJG releases.

Other documentation files in the distribution are: User documentation: install.doc How to configure and install the IJG software. usage.doc Usage instructions for cjpeg, djpeg,jpegtran, rdjpgcom, and wrjpgcom. *.1 Unix-style man pages for programs (same info as usage.doc). wizard.doc Advanced usage instructions for JPEG wizards only. change.log Version-to-version change highlights. Programmer and internal documentation: libjpeg.doc How to use the JPEG library in your own programs. example.c Sample code for calling the JPEG library. structure.doc Overview of the JPEGlibrary's internal structure. filelist.doc Road map of IJG files. coderules.doc Coding style rules --- please read if you contribute code. Please read at least the files install.doc and usage.doc. Useful information can also be found in the JPEG FAQ (Frequently Asked Questions) article. See ARCHIVE LOCATIONS below to find out where to obtain the FAQ article. If you want to understand how the JPEG codeworks, we suggest reading one or more of the REFERENCES, then looking at the documentation files (in roughly the order listed) before diving into the code. OVERVIEW ======== This package contains C software to implement JPEG image compression and

decompression. JPEG (pronounced "jay-peg") is a standardized compression method for full-color and gray-scale images. JPEG is intended forcompressing "real-world" scenes; line drawings, cartoons and other non-realistic images are not its strong suit. JPEG is lossy, meaning that the output image is not exactly identical to the input image. Hence you must not use JPEG if you have to have identical output bits. However, on typical photographic images, very good compression levels can be obtained with no visible change, and remarkably highcompression levels are possible if you can tolerate a low-quality image. For more details, see the references, or just experiment with various compression settings. 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. Forlegal reasons, we are not distributing code for the arithmetic-coding variants of JPEG; see LEGAL ISSUES. 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...
