DIUcl is a freeware port of UCL to Borland’s Delphi language. UCL is the compressor used in the UPX Ultimate Packer for Executables by Markus F.X.J. Oberhumer. Decompression is extremely fast, and requires very little memory. The author claims that the decompressor fits into less than 200 bytes of code. Supports in-place compression and decompression. Using DIUcl is very simple: There’s a compress() function that compresses a block of memory, and there’s a decompress() function that handles decompression.
Real-time decompression should be possible for virtually any application, which makes DIUcl the ideal tool to compress your database Blob fields.

Version 1.10 is shipping as of June, 2003.
