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 jpeg-info@uunet.uu.net 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.
LEGAL ISSUES
============
In plain English:
We don't promise that this software works. (But if you find any bugs, please let us
know!)
You can use this software for whatever you want. You don't have to pay us.
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) 1991-1998, Thomas G. Lane. 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, ltconfig, ltmain.sh). Another
support script, install-sh, is copyright by M.I.T. but is also freely distributable.
It appears that the arithmetic coding option of the JPEG spec is covered by patents
owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be
used without obtaining one or more licenses. For this reason, support for arithmetic
coding has been removed from the free JPEG software. (Since arithmetic coding
provides only a marginal gain over the unpatented Huffman mode, it is unlikely that
very many implementations will support it.) So far as we are aware, there are no
patent restrictions on the remaining code.
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."
