--- Comment #12 from J <i...@j-pfennig.de> --- Thank you for your detailed reply. Here are my conclusions: 1. My systems are Debian Bookworm, libde265-1011-1 2. Your plugin tool says libde256 does only 8-bit but on GIT they say that libde256 does support HDR (which makes little sense with 8-bit). Where does the 8-bit limit come from? 3. There should be a warning when saving from a 16 bit workspace to 8-bit Heif 4. IM does HEIF 16 bit, why not using IM to load HEIF? 5. Saving from a 16-bit workspace should offer a way to select the depth. This is a feature request. I found that 10-bit depth is a good compromise between space and quality. 6. If DigiKam does not like to support 10-Bit Tiff (which is not standard but understood by IM) then try to reduce colors by masking away lower bits. 7. Currently Digikam offers limited 16-bit support, best for TIFF. Hopefully the future development will allow a wider support for HiColor and or HDR. 8. Your Image Loader Plugin architecture is quite nice, but for several reasons I would like to use IM codecs, but the IM Loader cannot be selected for HEIF, JPegXl ... ? It seems that there is a long way to go for DigiKam to reach full HiColor/HDR support. Until then I will continue to use intermediate 16-bit Tiffs and convert to/from archive format (JPeg2000) via IM. Jürgen 24.
