By default, LibRaw extracts ActiveArea image (3040x2014)
Suppose we are discussing the latest public version (https://github.com/LibRaw/LibRaw, master branch):
DefaultCrop tags are parsed into imgdata.sizes.raw_inset_crops[0]
This crop can be applied via: LibRaw::adjust_to_raw_inset_crop(1)
BUT:
DefaultCrop top/left in this specific file is odd and will be rounded to nearest even margin, so image will be cropped to 3007x1999 starting at 16,8
There is no way to avoid this in current LibRaw (this change was implemented in LibRaw 0.20)
You may switch to LibRaw pre-0.20 (0.19 or so) with LIBRAW_PROCESSING_USE_DNG_DEFAULT_CROP flag set to params.raw_processing_options
OK, understood.
