SUMMARY using AVIF instead of raw format to save place. need more then 8bits depth. There is no selection for AVIF export bit depth. DigiKam default to 8 bits. Would like to use 12 bits like in imagemagick STEPS TO REPRODUCE 1. in editor, export a 12 or 16bits AVIF image, select AVIF format (same thing with a 16bit png input image or a raw nef input image) 2. dialog propose the qualtity, but no bit depth OBSERVED RESULT checking the saved image : Digikam says 8 bits, imagemagick also says 8 bits EXPECTED RESULT Enhancement : either have the bit depth selectable (like the "-depth 12" in image magick), or default to 12 bits SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
The bit-depth to encode must be follow the bit-depth of original image loaded in editor or BQM. If RAW is processed as 16 bits, the exported AVIF must be encoded accordingly. Gilles Caulier
