[Pkg-kde-extras] Bug#1033575: digikam: bookworm build: No 16-bit color in jpeg2000 and heif, missing gmic-qt

[J. Pfennig]

Package: digikam
Version: 4:7.9.0-1+b2
Severity: important

Dear Maintainer,

Thanks for building digikam for bookworm. As you shurely know this build
is quite important as recent appimage upstream builds crash on bookworm
(I believe that's a know problem).

The latest usable appimage for bookworm was 7.7 (7.8 loads too slow, 7.9
and 7.10 crash).

The 7.7 appimage (and earlier) correctly load jpeg2000 images with more
than 8-bits per color-channel (I use 10-bits for my purposes). 

Anyhow, the 7.9 build for bookworm loads jpeg2000 and heif only with
8-bit per color-channel (implied down-conversion). Tiffs with 16-bit per
channel load correctly (unfortunately only 8/16-bit tiffs work with
kde's libtiff). Needless to say that imagemagick 7.1.0 works fine with
8/10/16-bit tiff/jpeg2000/heif.

Also gmic-qt is missing in the debian build (it works fine if the plugin
is copied from the app-immage). gmic-qt for digikam did never support
16-bit color, but that's an upstream-bug.

Yours
Jürgen
