Copyright (C) 1994-1997, Thomas G. Lane. This file is part of the Independent JPEG
Group's software. For conditions of distribution and use, see the accompanying READ-
ME file.
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.
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 par-
ticular purpose. This software is provided "AS IS", and you, its user, assume the enti-
re risk as to its quality and accuracy.
This software is copyright (C) 1991-1998, Thomas G. Lane. All Rights Reserved ex-
cept as specified below.
Permission is hereby granted to use, copy, modify, and distribute this software (or por-
tions thereof) for any purpose, without fee, subject to these conditions:
libjpeg
(1) If any part of the source code for this software is distributed, then this READ-
ME file must be included, with this copyright and no-warranty notice unalte-
red; 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 respon-
sibility 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 commer-
cial products, provided that all warranty or liability claims are assumed by the pro-
duct vendor.
ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole pro-
prietor 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 distribu-
tion terms of the Free Software Foundation; principally, that you must include sour-
ce code if you redistribute it. (See the file ansi2knr.c for full details.) However, since an-
si2knr.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 co-
pyright by the Free Software Foundation but is freely distributable. The same holds
for its supporting scripts (config.guess, config.sub, ltconfig, ltmain.sh). Another sup-
port 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 ow-
ned 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 cod-
ing has been removed from the free JPEG software. (Since arithmetic coding provi-
des 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 res-
trictions on the remaining code.
