ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

This minor enhancement of Rec. ITU.T T.834 | ISO/IEC 29199-4 extends and enhances the set of test
streams for Rec. ITU.T T.832 | ISO/IEC 29199-2 in two ways: First, additional test streams cover
features than had either not yet been tested in earlier revisions or did not exist in earlier versions in the
standard. Second, extensions made to Rec. ITU.T T.802 | ISO/IEC 15444-2 allow the wrapping of JPEG XR
codestreams in the JPEG 2000 file format, for which new reference streams are included.
Three new test streams cover the “red-blue not swapped” flag recently introduced in Rec. ITU.T T.832
| ISO/IEC 29199-2, and the DCLP-QP flag, which was not covered in earlier tests. The “trim-flexbits”
feature was only partially tested in earlier revisions of this Recommendation | International Standard,
and test streams for this have been added. An additional set of test streams covers the spatial rotation
The second block of tests cover the new boxed-based file format introduced in AMD.3 of Rec. ITU-T T.802 |
ISO/IEC 15444-2.
The new set of test streams is not included as an electronic attachment to this text due to size constraints,
but is available at the following URL:

7.27 Reference file set Red-Blue-Not-Swapped
This collection of 6 .jxr files contains images in the BGR555, BGR565 and BGR101010 colour format that
make use of the RED_BLUE_SWAPPED_FLAG of the codestream, indicating a component order in which
red is in the first and blue in the last channel. The set consists of the files
