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.
