imgdata.image is 16 bit/linear
image->data is 16 bit (output_bps set to 16) and gamma corrected (as far as I could understand from your code)
Both imgdata.image and image.data are cropped (by imgdata.sizes top/left_margin and width/height), while imgdata.rawimage.* is not cropped.
Also, imgrata.rawimage contains unaltered raw values, black level not subtracted
Could you please ask more specific question?
