Oh... Can't believe I didn't think of that. Exported a TIFF first try with /usr/src/app/libraw/bin/dcraw_emu -dngsdk -T -Z out.tiff /usr/src/app/testfiles/unreadable.dng.

I'm assuming then that the reason it didn't actually work in ImageMagick is because their DNG code is missing support for it? https://github.com/ImageMagick/ImageMagick/blob/main/coders/dng.c

I don't see the dng_host object in here. That's all that is required to allow unpacking these DNGs right? I'm already compiling against the working libraw and ImageMagick has other DNG reading code, but is just missing the dng_host for the Adobe DNG SDK?

Thank you very much for the incredibly fast response though!
