We're all talking about 1bit RGB. Like 1bit of Red, 1bit of Green, 1bit of
Blue. So 1 bit per sample, but 3 bits per pixel. Got a use for that?
My guess is, when the hardware is capable of it at all, it exists only
out of a sense of completeness.

Looks like an XSane bug, if the A3 Pro actually supports 1bit lineart
Did XSane let you choose binary PBM (that's what you want) ?

Nah, you need 1bit Black and white. Color is the stuff with red, and
purple and so on. SANE has 1bit B&W (it works upside down which is
how this whole thread started... but it works). The question is if we
have (working) 1bit RGB, and if so how and to what end?
