Description

UCL is a portable lossless data compression library. It implements a number of algorithms with the following features: - Decompression is simple and *very* fast. - Requires no memory for decompression. - The decompressors can be squeezed into less than 200 bytes of code. - Includes compression levels for generating pre-compressed data which achieve an excellent compression ratio. - Allows you to dial up extra compression at a speed cost in the compressor. The speed of the decompressor is not reduced. - Algorithm is thread safe. - Algorithm is lossless. UCL supports in-place decompression.
