This International Standard defines a normative but optional file format for storing compound images using the JPEG 2000 file format family architecture.

This format is an extension of the JP2 file format defined in ITU-T Rec T.800 | ISO/IEC 15444-1 Annex I and uses boxes defined for both the JP2 file format and the JPX file format defined in ITU-T Rec T.801 | ISO/IEC 15444-2 Annex M.

This standard is useful for applications storing multiple pages, images with mixed content, and/or images that need more structure than provided in JP2. Applications that implement this file format shall implement it as described in this International Standard.

This International Standard - specifies a binary container for multiple bi-level and continuous-tone images used to represent a compound image, - specifies a mechanism by which multiple images can be combined into a single compound image, based on the Mixed Raster Content model - specifies a mechanism for grouping multiple images in a hierarchy of layout objects, pages and page collections, - specifies a mechanism for storing JPEG 2000 and other compressed image data formats, - specifies a mechanism by which metadata can be included in files specified by this International Standard.
