I bought new Canon DSLR and i've discovered there is no support in kde for new cr3 raw support. It will be nice to get thumbs and general Plasma support for cr3 files as is for cr2 Thx

It will be nice to get thumbs and general Plasma > support for cr3 files as is for cr2 CR3 files are supported by LibRAW 0.21, this means that you need a very updated distro. Note that a GWenView fix was added latest week for RAW support (https://bugs.kde.org/show_bug.cgi?id=463132). The RAW plugin of KImage-plugins already supports CR3 files (https://invent.kde.org/frameworks/kimageformats/-/blob/master/src/imageformats/raw.cpp line 44). If compiled using LibRAW less than 0.21, the CR3 images are not rendered well.
Adding to this, I can confirm that Gwenview does indeed support CR3 files. However, Dolphin DOT NOT show their thumbnails even with "RAW Photo Camera Files" is selected in the Previews section.
I have added libraw-dev and libjxl-dev to the kimageformats deps for neon unstable. this should provide support for cr3 and other image formats. https://invent.kde.org/neon/kde/kimageformats/-/commit/5601dee7d961aeedd58bd72d8750c8a0bee5171e
I just tested and even though Dolphin isn't generating the thumbnails for CR3 files, I opened the folder containing my files with Gwenview and that did the trick. I don't think that's ideal as Dolphin should be able to generate thumbnails without having to run any other program, but at least a workaround exists.
Status of this issue is resolved but at this point of current stable version of neon is not working. Is that mean the next or near updates for neon will provide that cr3 support for Dolphin and Gwenview, so all libs will be updated and apps will be compiled using newest libs?

Anyway, I'll do some test on my CR3 files. Can you attach a CR3 file (just to verify that there are no different types of cr3 files)? PS: latest version of KIO thumbnailer (used by Dolphin) does not create previews if the stimated memory usage is too high (grater than 1/3 of availble free ram). This mechanism is used for images of several GB certainly not for the camera files.

I don't have the knowledge to fix this but once it is fixed the builds will filter into unstable and then stable and then release.
Created attachment 155430 [details] CR3 preview from Dolphin I tried now on my unstable debian. I put 2 CR3 files (EOS R6 Mark 2 and EOR R5) in a folder and opened it with Dolphin. He created the previews for me.

My debian has: - kimageformat-plugins 5.101.0-2 - dolphin 4:22.12.1-1 Note the black borders of the preview caused by LibRaw 0.20 (the one installed on my debian). If you install LibRaw 0.21 you need to recompile the kimageformat-plugins.
