JPEG 2000 Code Stream
Yet another extension for raw JPEG 2000 streams.
JPC is another file extension used for JPEG 2000 codestreams. It is synonymous with J2C and J2K, representing the raw compressed data without the JP2 container.
Identical to J2C and J2K. The extension 'JPC' is less common but supported by libraries like ImageMagick and OpenJPEG.
Part of the JPEG 2000 standard. The proliferation of extensions (jpc, j2k, j2c) stems from early committee drafts and specific software implementation preferences.
Palm Database
The generic database container for Palm OS.
PDB (Palm Database) is the standard file format for all data on Palm OS devices, from address books to e-books. In the context of images, a PDB file acts as a container for 'Palm Pixmap' images, typically storing them as a series of records. It was the only way to get data onto a Palm pilot.
A PDB file consists of a header (name, attributes, creation time) and a list of records. For images, these records contain the bitmap data (often compressed with RLE/PackBits). ImageMagick treats PDB files as a multi-image sequence if multiple bitmaps are stored in the records. The format is strictly structured to map directly to the device's RAM storage model.
Created by Palm Computing in 1996. It was designed to facilitate 'HotSync' between the handheld's RAM and the desktop PC. It became ubiquitous in the early 2000s PDA era.
