The older Mustek SCSI scanners could send 1 bit per color RGB so there are devices that can. But I have never seen the benefit. I mean, 2 "colors", black and white are ok. 256 (or more) also. But 8? Ok, that's like CGA (?). What to do with these images? I mean, it's RGB so it can't be "lineart + some IR stuff". On the other hand, if we exactly define these modes nobody is hurt even if they are never used. Bye, Henning
