The SANE API knows none of these, just raw RGB or greyscale.  Take another 
look at the spec - the information really is all there.

If your scanner sends you some special format then the SANE backend must 
translate it to raw data, eg: the dell1600n_net backend receives colour 
scans in JPEG format for which it uses libjpeg to convert to RGB data.
