|Free STDF Resources : : liblzw|
As support was added to libstdf to read compressed files, the request came up to read LZW compressed files. Many might be familiar with this compression algorithm via the classical UNIX programs compress and uncompress which manipulate files named with a .Z extension, or perhaps the usage of LZW in compressing GIF/TIFF image data.
Since the compression algorithms were ripped out of the public-domain package ncompress, liblzw has also been released into the public-domain for people to do with as they will. Just please send me bugfixes as you find them :).
One last note for those of you coming late to the party; all existing patents on the LZW algorithm have expired world-wide. So LZW is now patent free (whoopee!).Status
The current implementation supports the open/read/close functions since that is all I require at this time for reading files in libstdf. Maybe if there's interest, more features can be added.Download
You can find plenty of info on the LZW algorithm (just use Google), but for fun, here's some helpful links.
