[sane-devel] grey 4bit/pixel

[Shashi Kumar M.S.]

hi, 
 
iam searching a scanner that supports at about 300 dpi and 4 bit /pixel grey 
scanner. i found from the scanner that most of the scanner support 8/16 bit 
depth in grey mode. 
 
is there any way to modify this code to support 4 bit grey scale depth per 
pixel. 
 
all suggestions are welcome 
 
with regards
