 Custom size: offers variable scan size from (1.85” x 2”) to (4.1” x 9”) (W x H)
Note: If the scan size is smaller than the actual document, the image will be cropped to the
size defined by the scan size.
Color Scheme: Color scheme defines the number of colors used to display the
image. In general, the higher the number of colors, the better and clearer is the
image. However, please bear in mind that more colors result in a larger file size.
ScanShell offers the following color schemes:
True color: 24-bit color image
256 colors: 8-bit color image
256 shades of gray: 8-bit gray image
Black and white: 1-bit image
As mentioned above, more colors mean larger image file size. The relation between
color scheme and file size can be defined approximated as follows:
File size = 2
number of bits
