.I Scan Mode
The
.I --mode
switch selects the basic mode of operation of the scanner valid choices are
.I Binary, Gray and Color.
The Binary mode is black and white only, Gray will produce 256 levels of gray
or more depending on the scanner and Color means 24 bit color mode or more
depending on the scanner. Some scanners will internally use 36 bit color,
the external interface however does only support 24 bits.

The
.I --depth
option selects the bit depth the scanner is using. This option is only available
for scanners that support more than one bit depth. Older scanners will always
transfer the image in 8bit mode. Newer scanners allow to select either 8 bits
or 12 or 14 bits per color channel. For a color scan this means an effective
color depth of 36 or 42 bits over all channels. The valid choice depend on
the scanner model.
The
.I --dropout

are None, Red, Green and Blue.
