| [e1d7dec] | 4 | <para>The libungif package contains libraries for reading all
|
|---|
| [c2ee009c] | 5 | <acronym>GIF</acronym>s and writing non-compressed ones as well as programs for
|
|---|
| [e1d7dec] | 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>

|

| [c2ee009c] | 11 | <para>The reason libungif only writes non-compressed <acronym>GIF</acronym>s
|
|---|
| [e1d7dec] | 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
|
|---|
| [c2ee009c] | 14 | decompression routines do not seem to be limited in this way. Note that this
|
|---|
| [e1d7dec] | 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>
