debug log
You already know from Bug 466821 that the XCF image loader is part of the KImageFormats-Plugins. Maik You can see from this error message that it is currently not implemented: kf.imageformats.plugins.xcf: Unhandled mode XCFImageFormat::GIMP_LAYER_MODE_NORMAL Maik I discover now PcmanFm-Qt and PcManFM gtk3 can display multilayers XCF thumbnails, i'm wondering how it works. https://archlinux.org/packages/?q=pcmanfm As far as I know, Gimp creates a thumbnail in the thumbnail cache when you save an image. This is displayed by file managers. Maik (In reply to Maik Qualmann from comment #5) > As far as I know, Gimp creates a thumbnail in the thumbnail cache when you > save an image.

Only PCmanfm 1.3.2 (Gtk3) can display XCF multilayers thumbnails normally Issues with XCF layers files is old story. This one was reported more seven years ago https://bugs.kde.org/show_bug.cgi?id=360806 Same time, it was reported to ImageMagick team too https://github.com/ImageMagick/ImageMagick/issues/1544 Dev comment: "Its not a bug. ImageMagick does not support Gimp 2.10 .XCF images. We may support the format in the future but currently we do not have an ETA on when support will be added." I'm wondering if other soft than IM, Kimageformats or Graphicsmagick, exist to display XCF files with layers or/and 16 bits XCF files. A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kimageformats/-/merge_requests/226 (In reply to maderios from comment #0) > Created attachment 162972 [details] @maderios are you the author of the image? If yes, can we include it in kimageformat repository as test case?

Added copyright info to XCF
I added the copyright info you wrote to the XCF and I will include in the KImageFormat repo for the regression tests.
