To allow users to process files captured by their (invalid) equipment

LibRaw internal file offsets are 32-bit and **signed** in many places, so 2GB is real current limit. We plan to switch to 64-bit offsets in some future, but no time...

I didn't understand the question, sorry. You use open_bayer() call, so the bayer pattern you provide to this call should match input data bayer pattern.

Also, you need color data extraction from files which provides color data (DNG, digital backs, several other formats). BTW, LibRaw may use RawSpeed as (faster) decoder for about two years....

As I can see, darktable uses own built-in color data (src/external/adobe_coeff.c) copypasted from dcraw

yes, for some cameras it is better to extract it from file. I do not see some generic interface for it in RawSpeed.

BTW, you say 'generated from the Adobe DNG converter directly'. Is there any script or something? I'm interested to extract Adobe's BaselineExposure values for all cameras....

Thanks, but this script extracts data from DNG file, not from DNG convertor. I use Exiftool, not exiv2 for it, but it is nearly the same. The problem is there...

Color conversion, surely, should be separate. But raw decoding library should unpack color data from raw files (it these raw data contains color data) and pass it to calling application....
