Loading .jxr with HDR colors - Good_Punk - 11-17-2020
Hi,
I've taken a few HDR screenshots with Windows Game Bar. They are in the .jxr file format. I can load them in Gimp but there's a message that the HDR colors will be flattened. Is there some way or something planned to load them with HDR support?
I'm looking all over the internet to find a way to convert .jxr to .avif format with HDR colors but so far I've found no (free) way to do that.

Have you added a plug-in to GIMP to handle the jxr files as my GIMP 2.10.22 on Windows doesn't seem to recognize them? (although I can't find any examples to try)

There is a file-jxr plugin https://github.com/chausner/gimp-jxr but it is 4 years old and for Gimp 2.8
Gives 8 bit conversions. This using linux https://i.imgur.com/SwfvKai.jpg I had a look around but nothing any better so far.
edit:
Again linux: a command line utility: http://manpages.ubuntu.com/manpages/bionic/man1/JxrDecApp.1.html
At least that gets a 16 bit tiff that opens in Gimp without that conversion warning: https://i.imgur.com/2hugLoj.jpg
.avif format ? I know that the linux flatpak Gimp 2.10.22 supports avif but do not have the flatpak installed on this computer.
Windows users: maybe run a linux in virtualbox

Thanks for the info... I've been using Gimp 2.10.22 and had installed file-type plugin for jxr. But yeah as mentioned they don't support HDR.
It's really strange to me that something to seemingly straight-forward like uploading a screenshot is so complicated.... I just hope .avif will get the wide-spread support that people say it will.
