About JPM Format

JPEG 2000 Compound Image

JPEG 2000 for multi-layer documents.

Overview

JPM (JPEG 2000 Part 6) is a compound image file format. It is designed for storing document images that contain a mix of text and graphics, using a Mixed Raster Content (MRC) model. It allows for different compression methods to be applied to different 'layers' of the image (e.g., sharp edges for text, smooth gradients for photos).

Technical Details

JPM splits an image into multiple layers (e.g., background, foreground mask, foreground color). Each layer can be compressed differently (e.g., JBIG2 for text mask, JPEG 2000 for background photos), optimizing both quality and file size for scanned documents. This is significantly more efficient than compressing an entire scanned page as a single JPEG 2000 image.

History

Part of the JPEG 2000 standard (ISO/IEC 15444-6), specifically targeting the document archival market.

Common Use Cases

  • •Document Archival: Scanned documents with mixed content.

Advantages

  • Efficiency
  • Legibility

Limitations

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
