ansi2knr.c is included in this distribution by pem1ission
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."
