|
---|
[014d11ad] | 25 |
|
---|
[a249d64] | 26 | <para>The <application>libungif</application> package contains libraries for
|
---|
| 27 | reading all <acronym>GIF</acronym>s and writing non-compressed ones as well as
|
---|
| 28 | programs for converting and working with <acronym>GIF</acronym> files. The
|
---|
| 29 | libraries are useful for any graphics program wishing to deal with
|
---|
| 30 | <acronym>GIF</acronym> files while the programs are useful for conversion
|
---|
| 31 | purposes as well as cleaning up images.</para>
|
---|
| 32 |
|
---|
| 33 | <para>The reason <application>libungif</application> only writes non-compressed
|
---|
| 34 | <acronym>GIF</acronym>s is due to a legal issue with <acronym>LZW</acronym>
|
---|
| 35 | compression (which Unisys claims a patent on). Reading <acronym>GIF</acronym>s
|
---|
| 36 | is not a problem as the decompression routines do not seem to be limited in
|
---|
| 37 | this way. Note that this has in the past been disputed. The best way to avoid
|
---|
| 38 | this whole mess is to simply use <application>libungif</application> for
|
---|
| 39 | looking at <acronym>GIF</acronym> images on the web, while in any pages which
|
---|
| 40 | you design, use the open source <acronym>PNG</acronym> format instead (which
|
---|
| 41 | uses, not surprisingly, the <application>libpng</application> library) which
|
---|
| 42 | has no patent issues at all.</para>
