CAN/CSA-ISO/IEC 15444-6:15 (R2024) ✓ Most Recent

Preface:

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

For brevity, this Standard will be referred to as "CAN/CSA-ISO/IEC 15444-6" throughout.

This Standard supersedes CAN/CSA-ISO/IEC 15444-6:04 (adoption of ISO/IEC 15444-6:2003).

At the time of publication, ISO/IEC 15444-6:2013 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.

Scope:

This Recommendation | 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 Rec. ITU-T 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 Rec. ITU-T T.801 | ISO/IEC 15444-2 Annex M. This Recommendation | International 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 Recommendation | International Standard. This Recommendation | 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 (MRC) 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 Recommendation | International Standard.
