Alex,
Thanks for your reply. I will use the COLOR function to serve as an index into the cdesc.
I actually figured out what I was doing wrong. I got the bit order of the filters field wrong. It says that filters represents an 8x2 area with 2 bits per pixel. I assumed that bits 31-30 and 29-28 corresponds to the top two pixels in this 8x2 area. But it turns out that bits 0-1 and 2-3 correspond to the top two pixels in this 8x2 area. I tested this hypothesis for a bunch of files and it seems to hold. Hope my understanding this correct.
Also, what does the colors field in the libraw_iparams_t represent?
