Adaptive LZW compression

This library provides functions to pack and unpack data using an adaptive LZW algorithm. Note that this library is not an interface to other well known packing/archive formats like .zip/.7z/.gz etc., but provides the LZW algorithm in its own library context only.

Table of Contents

LZW FUNCTIONS

• LzwPack$
  • compress the given data using the LZW algorithm
• LzwUnpack$
  • decompress data packed by the LzwPack$() function

HELPER FUNCTIONS

• GetCRC32
  • calculate the CRC32 checksum of the given data
