By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Fabio Rossi 2019-09-20 04:55:19 CDT

Currently tdelibs uses jasper in kimgio to support jpeg2k images.

Jasper is the "reference implementation of the codec specified in the JPEG-2000 Part-1 standard" (from https://www.ece.uvic.ca/~frodo/jasper/). Sadly it also has incomplete JPEG-2000 support and is now unmaintained... It has also a lot of security issues.

OpenJPEG is "an open-source JPEG-2000 codec written in C" (from http://www.openjpeg.org). It has better JPEG-2000  support and has the advantage of still being maintained. 

Many distributions have started removing jasper from their repositories, i.e. Gentoo (https://bugs.gentoo.org/show_bug.cgi?id=689784). Please see also the link https://github.com/mdadams/jasper/issues/208 with more details

What about migrating to openjpeg support and removing jasper?

Yes, replacing jasper with openjpeg is one of the tasks we would like to do.

For the time being, I have not been looking for any document that would be a guide to make our transition easier. You know of a document that compares the jasper × openjpeg API?
