Add test images

description

There is shortage of test images in JPEG XR format.

Please, add a set of standard test images in JPEG XR format covering at least the basic features of JPEG XR.

Ideally, covering some of the unique features like RGBE/HDR.

Such images should be released under terms of a permissible license, ideally in public domain.

The ITU standard comes with a set of conformance test files, see http://www.itu.int/rec/T-REC-T.834-201410-I/en.

Thanks for the links. This is a very good dataset of JPEG XR images.

It forwards to direct download from the ITU-T test signals database at http://handle.itu.int/11.1002/2000/10648

Unfortunately, the licensing / terms of use are not clear
  • The .zip package does not contain any licensing info.
  • The download page says:
The signals available here constitute part of the corresponding ITU-T Recommendations and are protected by copyrights laws.
You may use them during product or service development for the purpose of implementing the corresponding ITU-T Recommendations.
Does implementation of a client based on jxrlib fit under the vague "purpose of implementing the corresponding ITU-T Recommendations"?


For example, I'm adding JPEG XR support based on jxrlib to GDAL (Geospatial Data Abstraction Library).

Does it fit the above mentioned purposes?


Why not releasing the test images under terms of a permissive / FOSS-friendly license or in public domain?

I would think your use case is covered by the licensing terms but I can't give you a definite answer since I'm not involved in jxrlib or the ITU standard. You may want to look on the ITU website for more information. Unfortunately, this repository here seems to be no longer maintained.

By the way, you may want to check out this pull request. It has never been officially merged but appears to contain bugfixes and improved progressive decoding, in case you plan to make use of that.

Christoph, thanks a lot!

I have gained such impression. That's pity!
