Short answer....by calling the Unix "uncompress" command in a subprocess. Not too good of a solution if you want to make a Mac or Windows version. A further reading shows that the author isn't convinced that decompression algorithms are allowed (which would make gzip illegal). As if that weren't bad enough, he has a link to Unisys ( http://www.unisys.com/unisys/lzw/ ) where they claim that you need to get a separate license from them to *use* any software anyone else wrote that contains lzw, even if the author also had a license. They go on to point out that GIF, Postscript, and PDF all use lzw. Yuk. Of course Adobe has bribed...er..purchased the proper license for their tools (http://www.adobe.com/support/salesdocs/f636.htm ). As the patent issue prevents the creation of a free PDF tool, I dobut they are too broken up over it. -- T.E.D. http://www.telepath.com/~dennison/Ted/TED.html Sent via Deja.com http://www.deja.com/ Before you buy.
