Overview

ISO/IEC 29199-5:2012/Amd 1:2015 is an important amendment to the JPEG XR image coding system reference software standard. Published by ISO in collaboration with IEC and ITU-T, this amendment extends the capabilities of the reference software, primarily by adding support for the Boxed Based File Format. This update addresses critical decoding and encoding issues in previous software releases and enhances interoperability by supporting two key JPEG XR file formats: the traditional tag-based format and the advanced box-based format.

This amendment is technical guidance for developers and implementers working with JPEG XR, a high-efficiency image coding system designed for superior compression performance and advanced pixel format support.

Key Topics

  • Extension of Reference Software
    The amendment updates the JPEG XR reference software to release 1.41, introducing enhanced stability and features, including:

    • Graceful handling of pixel formats with 555/565/101010 bit RGB channel data.
    • Correct reconstruction of n-channel pixel formats with interleaved alpha channels.
    • Legacy support for red/blue channel ordering through command-line options.
  • Support for Boxed Based File Format
    The new release supports the ISO box-based file format specified in ITU-T Recommendation T.801 (ISO/IEC 15444-2), alongside the tag-based format from ISO/IEC 29199-2. This dual support allows:

    • Greater flexibility in JPEG XR file management.
    • Testing and implementation of new file formats with backward compatibility.
  • Command Line Options

    • -g: Swaps red and blue color channels in specified pixel formats to support legacy formats.
    • -x: Enables encoding of images in the box-based file format.
  • Improved Robustness and Compatibility
    Fixes to previous software crashes and encoding/decoding bugs increase reliability for a wide range of imaging applications.

Applications

  • Image Compression and Storage
    Enables efficient encoding and decoding of high-quality images with advanced pixel formats, ideal for digital photography, medical imaging, and archival purposes.

  • Software Development and Testing
    The updated reference software serves as a critical tool for developers implementing JPEG XR codecs, ensuring full compatibility with new file formats and legacy applications.

  • Multimedia Systems
    Supports multimedia platforms requiring both high fidelity and flexibility in image file formats by utilizing the box-based and tag-based JPEG XR formats.

  • Digital Content Distribution
    Facilitates standardized image delivery with enhanced compression efficiency and broader device compatibility through ISO-compliant implementations.

Related Standards

  • ISO/IEC 29199-2: JPEG XR image coding system – File format (tag-based format)
  • ISO/IEC 15444-2 / ITU-T T.801: JPEG 2000 Part 2 – Box-based file format specification
  • ITU-T Rec. T.835: JPEG XR image coding system reference software base
  • ISO/IEC Directives: Procedures and editorial rules governing ISO/IEC standards development

By adhering to ISO/IEC 29199-5:2012/Amd 1:2015, organizations and developers ensure conformance with internationally recognized practices for image coding using JPEG XR, promote interoperability, and support ongoing innovation in image processing technologies. This amendment enhances the practical value and adaptability of JPEG XR for a variety of professional and consumer applications.
