WinAce released a new version of their archiving program at the end of 2000, promising exciting new features, such as support for Gzipped files, proprietary EXE, sound, and picture algorithms, and the usual list of extras.
DCL user comment: I have never seen such a lovely archiving program. The best I have used so far. Winzip […]

by Dmitry Shkarin. Dmitry is the author of PPMd, a well know compressor. PPM is a powerful compression technology which has a reputation for being resource intensive. In this paper Dmitry adds bells and whistles to basic PPM and gets fantastic results.

Reader jcp said: Big problem: algorithm very slow, it’s impractical to search anything inside […]

Read and write JPEG2000 files from Photoshop with this plugin.
DataCompression.info reader Eric was disappointed with this product: Their plugin’s preview mode does not work. Without it, the plugin is horribly crippled. .

by David S. Taubman, Michael W. Marcellin. This rather pricey book is listed as a reference for engineers and researchers who want to understand the JPEG2000 standard. Taubman is the author of the Kakadu tools, which are included on the CD (licensing terms unknown.) Use the link on this web page to buy the book […]
