The IMGBOX commands have many different modifiers that can be used to change
the size and appearance of the signature image output by the scanner. Modifiers
affect the image that is transmitted, but do not affect the image in memory. Any
number of modifiers may be appended to the IMGBOX command.
Note: The IMGBOX command will return a NAK unless a window size (width and height) are
specified. See H - Height of Signature Capture Area (page 165) and W - Width of
Signature Capture Area (page 167).
IMGBOX Modifiers
A - Output Image Width
This option is used to size the image horizontally. If using this option, set the
resolution (R) to zero.
B - Output Image Height
This option is used to size the image vertically. If using this option, set the
resolution (R) to zero.
D - Pixel Depth
This indicates the number of bits per pixel in the transmitted image, which defines
whether it will be grayscale or black and white.
