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 prod-
ucts, 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 un-
likely 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 algo-
rithm; the resulting GIF files are larger than usual,
but are readable by all standard GIF decoders.
We are required to state that “The Graphics In-
terchange Format(c) is the Copyright property of
CompuServe Incorporated. GIF(sm) is a Service
Mark property of CompuServe Incorporated.”

PREAMBLE
The goals of the Open Font License (OFL) are to
stimulate worldwide development of collaborative

fonts to remain under this license does not apply
to any document created using the fonts or their
derivatives.
