JPEG XL support with new Microsoft WIC codec

Help & Support
1

Recently Microsoft released a new plugin to add .jxl support to Windows, similar to the ones mentioned in this FAQ entry.

Currently with the plugin installed:

  • thumbnails are generated
  • preview pane works, although it is quite slow for some reason, the whole pane goes completely dark for a second and then the image loads
  • DOpus viewer cannot handle the format

As far as I understand this new codec would fall within the current "Windows Imaging Component" Viewer Plugin present in DOpus and I was wondering if full JPEG XL support could be added to the program this way.

Thanks!

We should be able to add it to the WIC plugin if the new codec works OK.

The preview pane taking a long time to display the image suggests it might not work OK, though. :slight_smile: It'll probably be coming via the shell thumbnailer in that case (the same one thumbnails in Opus and File Explorer use), which likely calls the same codec.

Looking forward to future updates!

For some ridiculous reason that codec requires Windows 11.
