DNG and cam_xyz

Hi,

When processing DNG files, will "libraw" calculate a weighted matrix based on two color matrices, camera calibration matrices, etc.?

When I tried to print out "cam_xyz", the fields are all zeroes. Is there an "end" matrix that reflects the weighted matrix.

Also, when can "float cmatrix[3][4]" be used? what kind of conversion does it apply to?

Thanks a lot!
