XnView Software

The JPEG-XL developer released the new 0.10.3 build and the performance is faster than in previous builds (0.70 or 0.90).
Also there are several bug fixes. I tested the new DLL from this website (see below) and it works great with XnViewMP 1.74.
I usually convert pictures to JPEG with the jpegli encoder and the results are perfect. No problems at the moment.
I think the libjpegxl.dll is also used by the jpegli encoder of XnViewMP, so it could be useful for many users.

Maybe you can add it in the next XnViewMP release.

XnView use library from https://vcpkg.io/en/packages
Now they have version 0.10.2, and I hope Pierre will add this to XnView MP.

The developer of JPEG XL have already announced the release of version 0.11.0, which is planned in a few days from now.
The 0.10.3 release is just as a quick fix of a serious bug.
