The Unisys patent is definitely only on what are called LZ-78 type compression algorithms of which LZW is one. Actually, IBM has a similar patent, but only Unisys has made noises about enforcing it. See: http://www.gnu.org/philosophy/gif.html For a good explanation of the current status. They verify there that reading of LZW-GIF files is perfectly ok. It is only creating them that is an issue. The patent does expire in 2003 though. -Rasmus -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
