JPEG 2000 Code Stream
The raw code stream of a JPEG 2000 image.
J2C represents the raw code stream of a JPEG 2000 image, stripped of the file format wrapper (JP2). It contains the compressed image data but lacks the metadata and structural information found in a full JP2 file.
A J2C file is essentially the 'payload' of a JPEG 2000 file. It consists of a sequence of markers and compressed data segments. Because it lacks a container, it relies on the decoder to know the image parameters or infer them from the stream markers.
Defined in Part 1 of the JPEG 2000 standard (ISO/IEC 15444-1) alongside the JP2 file format.
Palm Pixmap
The graphics format for Palm Pilot PDAs.
The Palm Pixmap format is the native bitmap resource used by Palm OS devices (like the Palm Pilot, Tungsten, and Treo). It was designed for the constraints of early handhelds: low memory, low CPU power, and limited screen depth (initially 1-bit, then 4-bit grayscale, then 8/16-bit color).
Palm images are usually stored inside a pdb (Palm Database) container file. The pixel data itself supports multiple compression types, primarily PackBits (RLE) and ScanLine. It handles transparency via a designated transparent index color. The format is tightly coupled with the Palm OS resource manager structure.
Debuted with the original Palm Pilot in 1996. As screen technology evolved, the format was extended to support color and high density (double density) screens on devices like the Sony Clie and Palm Tungsten.
