data compression link collection


LZO is an implementation of an algorithm designed for embedded systems that have tight memory or speed requirements. While it won’t compress as well as algorithms such as deflate, it will make up for that by its thrifty use of your computing resources.


A .NET wrapper around the native LZO libraries.

The UCL Compression Library

UCL is a portable lossless data compression library written in ANSI C. This work is from Markus F.X.J. Oberhumer, known for LZO, UPX and more. reader Swift G. had this to say: Excellent library. The compression routines are fast and if you need binary compression this is the way to go.

LZO Streaming Code

Published in Source Code, LZO

Tom St Denis posted an article on comp.compression announcing free source code for streaming to and from files using the LZO engine. This link takes you to stream.c, modify it slightly to get stream.h, the corresponding header file.

Not Really Vanished

The home page for NRV, the next generation successor to LZO. NRV is a portable lossless data compression library written in C++. It offers pretty fast compression and *very* fast decompression. Decompression requires no memory. NRV is free under the GPL.

DCL reader Luigi T. saidIt would be very useful for my needs, but at the moment the source code seems to not be available.
