HS Compress is a software library (supplied with full C source code) which provides a programmer with a lossless compression / decompression algorithm based on RLE (runtime length encoding) The library may be used in telecommunications application or for fixed data compression. *HOW IT WORKS: Runtime Length Encoding (RLE): HS Compress library operates in buffer mode. It monitors the buffer data for presence of any four or more consecutive repetitions of the same character. If detected, the compression code, character and length are stored in the output buffer.
