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

its quality and accuracy.

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

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

Incorporated. GIF(sm) is a Service Mark property of CompuServe Incorporated."
