Select the form of the image data. Each option
below identifies a data format that specifies the
number of bits used to represent the tone of a pixel.
The more bits per pixel, the more tones and colors
you can capture in the scanned image. The
highest number of bits possible is 24 bit color (or
True Color), which can represent over 16 million
colors.
Note, however, that the output devices you use
should be capable of producing the same tones.
Also, the larger the bits per pixel value chosen, the
larger the size of the Image data.
Possible values are:
Black and White
16 Gray Scale
255 Gray Scale
Define the halftone processing applied to the
scanned image. You will generally want to select

scanner you are using. Possible values are:
