Description

Hi. Is there any near term plan to add DNG 1.7 (JXL lossy) support in near term...?

Support seems to exist already in Libraw, although in its compiling Adobe SDK has to be included. Below is a related topic with some instructions from Libraw devs which might be useful if/when implementing it:

Research direction

No darktable files, tests, or entry points are named. Start by reading the linked LibRaw issue #786 and its implementation instructions, then determine how DNG 1.7 with JXL lossy could be supported alongside the Adobe SDK requirement. Done means an agreed implementation path or working support with suitable verification.
