Overview
A PalmOS Database is the normal format in which data is stored on a PalmOS-based device. These devices lack a normal filesystem and instead store everything as part of a database. The .pdb extension is what ends up on files containing data exported from a Palm device to another system such as a PC. The one other format used on a Palm device is PRC, or Palm Resource Compiler.
The type of data stored in the file is indicated by a type/creator code: 8 ASCII characters starting at byte position 60.
As an image format
PDB files with type code vIMGView are supported as image files by some image processing programs.
It appears to be a paletted format supporting up to 16 colors. Images may be uncompressed, or use RLE compression.
Software
- ImageMagick (image files only)
