4 | <para>The libungif package contains libraries for reading all
|
---|
5 | <acronym>GIF</acronym>s and writing uncompressed ones as well as programs for
|
---|
6 | converting and working with <acronym>GIF</acronym> files. The libraries are
|
---|
7 | useful for any graphics program wishing to deal with <acronym>GIF</acronym>
|
---|
8 | files while the programs are useful for conversion purposes as well as cleaning
|
---|
9 | up images.</para>
|
---|
10 |
|
---|
11 | <para>The reason libungif only writes uncompressed <acronym>GIF</acronym>s
|
---|
12 | is due to a legal issue with <acronym>LZW</acronym> compression (which Unisys
|
---|
13 | claims a patent on). Reading <acronym>GIF</acronym>s is not a problem as the
|
---|
14 | uncompression routines do not seem to be limited in this way. Note that this
|
---|
15 | has in the past been disputed. The best way to avoid this whole mess is to
|
---|
16 | simply use libungif for looking at <acronym>GIF</acronym> images on the web,
|
---|
17 | while in any pages which you design, use the open source <acronym>PNG</acronym>
|
---|
18 | format instead (which uses, not surprisingly, the libpng library) which has no
|
---|
19 | patent issues at all.</para>
