NAME

   Compress::LZW - Pure-Perl implementation of scaling LZW

VERSION

   version 0.04

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::Decompressor

EXPORTS

   Default: 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.
