About J2C Format

JPEG 2000 Code Stream

The raw code stream of a JPEG 2000 image.

Overview

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.

Technical Details

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.

History

Defined in Part 1 of the JPEG 2000 standard (ISO/IEC 15444-1) alongside the JP2 file format.

Common Use Cases

  • Embedded Systems: Used where overhead needs to be minimized and metadata is unnecessary.
  • Video Streams: Can be used as a frame in a Motion JPEG 2000 stream.

Advantages

  • Compactness
  • Efficiency

Limitations

  • No Metadata
  • Compatibility

About PDB Format

Palm Database

The generic database container for Palm OS.

Overview

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.

Technical Details

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.

History

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.

Common Use Cases

  • E-Book Images: Images embedded in Peanut Press (eReader) books.
  • Application Assets: Storing sprites and icons for Palm apps.

Advantages

  • Container

Limitations

  • Complex
  • Obsolete
