170 N4680 2D Decoded Scan Engine User Guide
The IMGBOX commands have many different modifiers that can be used to change
the size and appearance of the signature image output by the scan engine. Modifi-
ers 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 171) and W - Width of
Signature Capture Area (page 172).
