You don't need to use Deflater. Plucker files can be created in several different ways by the distiller on your desktop computer: uncompressed, DOC compression, and ZLib compression. Uncompressed files don't need any decompression tool. DOC compression uses a decompression function built into PalmOS. ZLib compression creates smaller files than DOC compression, but it isn't implemented in the standard OS. Instead, it requires software you install on your palm for programs to deal with it. Any program could itself include the algorithms, or they might be included in what's commonly called a "shared library." SysZLib.prc is an example of one of these. What libraries implement are sets of generic tools for doing things that aren't otherwise supported by PalmOS. Other programs then access the functions within that library to do with them what they will. All the programs that were programed with a particular library in mind use the same copy of on your palm. Shared libraries allow us to save memory by keeping redundancy down instead of having every program implement the same function over and over again. Another advantage: if there's a bug found or a feature enhanced in an library, you only have to upgrade the one library to take advantage of it in every program that uses it. SysZLib implements Z compression and decompression algorithms (AKA "deflate/inflate" in PKZip terminology). Another common library you'll probably encounter is MathLib (which implements useful math functions). The particular SysZLib you get from http://www.copera.com/zlib-armlet/ is accelerated for people with Palm devices based on ARM processors (so every program you have that uses ZLib gets to take advantages of the accelerations. Plucker uses the functions within ZLib to decompress Plucker documents that were compressed with that particular algorithm. Deflater uses the functions within ZLib to compress and decompress arbitrary databases on your palm. -- Alan Hoyle - [EMAIL PROTECTED] - http://www.alanhoyle.com/ "I don't want the world, I just want your half." -TMBG Get Horizontal, Play Ultimate. _______________________________________________ plucker-list mailing list [EMAIL PROTECTED] http://lists.rubberchicken.org/mailman/listinfo/plucker-list
