This article describes STL-compliant iostream implementations that compress and decompress using the deflate and bzip2 algorithms. It makes it really easy to use compressed streams in your C++ app.
Updated July, 2003, to fix a gzip header problem.
Updated August, 2003 to fix a couple of minor problems.

This open source Linux project converts image files (JPEG, GIF, PNG, etc.) to Encapsulated PostScript, in what is supposed to be an efficient manner.
http://imgtops.sourceforge.net/PDF Compress
Free PDF Compressor that removes duplicate PDF objects, optionally takes advantage of new compression features of latest PDF specification (1.5), and optionally takes advantage of a new proposed format called “Compact PDF” that for many classes of documents compresses 30 - 60% better than what is possible in PDF 1.5.

This is a console-mode Linux program built for processing of video streams. Currently supported modules provide support for DVD format, DV, DivX, and more. Lots of good stuff in here for serious video production bloke.
Version 0.6.10 shipped in September, 2003.
http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/SuffixTree
An Open Source Suffx Tree implementation. Looks as though this might be oriented towards teaching applications, as it is an interactive application, not just an implementation of the data structure.
http://bioinformatics.rit.edu/~tex/publications/suffixtree/ANSI C implementation of a Suffix Tree
A C implementation of a Suffix Tree. This project also includes a Perl module that can use the C code.
http://cs.haifa.ac.il/~shlomo/suffix_tree/Cquantizer
This code project piece uses the octree algorithm to reduce the number of colors in a bitmap. Like most of the code project stuff, it is implemented as a class compatible with Visual C++ and MFC.
Last update of this article was September, 2003.
