NAME
Compress::LZW - Pure-Perl implementation of scaling LZW
VERSION
version 0.03
SYNOPSIS
use Compress::LZW;
my $compressed = compress($some_data);
my $data = decompress($compressed);
DESCRIPTION
"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.
FUNCTIONS
compress
Accepts a scalar, returns compressed data in a scalar.
Wraps Compress::LZW::Compressor
decompress
Accepts a (compressed) scalar, returns decompressed data in a scalar.
Wraps Compress::LZW::Deompressor
EXPORTS
"compress" "decompress"
SEE ALSO
The implementations, Compress::LZW::Compressor and
Compress::LZW::Decompressor.
Other Compress::* modules, especially Compress::LZV1, Compress::LZF and
Compress::Zlib.
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.
