Compress::LZW - Pure-Perl implementation of scaling LZW
use Compress::LZW; my $compressed = compress($some_data); my $data = decompress($compressed);
Compress::LZW is a perl implementation of the Lempel-Ziv-Welch compression algorithm, which should no longer be patented worldwide. It is shooting for loose compatibility with the flavor of LZW found in the classic UNIX compress(1), though there are a few variations out there today. I test against ncompress on Linux x86.
Accepts a scalar, returns compressed data in a scalar.
Accepts a (compressed) scalar, returns decompressed data in a scalar.
I definitely studied some other implementations that deserve credit, in particular: Sean O'Rourke, <SEANO> - Original author,
Compress::SelfExtracting, and another by Rocco Caputo which was posted online.
