That's perfect. I thought I should let you know, but I see it wasn't necessary
because you already knew.

Thanks for adding the 16bit functionality so quickly.

It works, as you told. However, in this version - I don't know why, cause I use
usually AppImages withuot issues - when I click right mouse button on a
thumbnail to show contextual menu, AppImage seems like freezed (even is greyed
by Plasma) and doesn't react to any user action (can resize window, but no
interaction at all).

In attached screenshot you can see the auto-showed metadata window that appear
when mouse is over a thumbnail, but it's freezed cause I click with right mouse
button over

Rafael,

If you want to test, try the current 8.3.0 pre-release AppImage bundle for
Linux here :

This problem is fixed in digiKam-8.3.0 with Bug 479497 and support for RGBA64
QImage from 16bit DImg. The prerequisite is that the KImageFormats support
this. A test here with a CR3 to JXL conversion results in a 16 bit JXL image.

As you use KDE framework 5.114.0, it's the current code used supporting 16 bits
color depth.

The JXL plugin loader use QImage container through the KImageFormat framework
from KDE:

Sound like the current code is able to handle > 8 bits colors depth:
