About J2K Format

JPEG 2000 Code Stream

Another extension for the raw JPEG 2000 code stream.

Overview

J2K is functionality identical to J2C. It represents a raw JPEG 2000 codestream without the JP2 file format wrapper. It is often used interchangeably with J2C and JPC in technical contexts.

Technical Details

Like J2C, a J2K file contains the wavelet-compressed image data (SOP/EPH markers). It relies on the decoder to interpret the stream markers correctly without the 'boxes' found in the JP2 container format.

History

Part of the ISO/IEC 15444-1 standard. The multiple extensions (.j2k, .j2c, .jpc) arose from different vendor implementations early in the standard's life.

Common Use Cases

  • •Medical Imaging: Sometimes found as raw streams inside DICOM wrappers.
  • •Texture Streaming: Used in some game engines (historical) for texture data.

Advantages

  • Compactness

Limitations

  • No Metadata
  • Confusion

About PALM Format

Palm Pixmap

The graphics format for Palm Pilot PDAs.

Overview

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).

Technical Details

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.

History

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.

Common Use Cases

  • •Legacy App Development: Creating assets for retro Palm OS apps.
  • •E-book Covers: PalmDOC e-books often embedded cover art in this format.

Advantages

  • Optimized for Low Power

Limitations

  • Dead Platform
  • Low Fidelity
