Signature Capture Optimize
If you will be using your scan engine to capture signatures frequently, you should
optimize it for this purpose. However, the speed of scanning bar codes may be
slowed when this mode is enabled. Default = Off.
Below is an example of a signature capture application. In this example, the aimer
is centered over the signature capture area and the trigger is pressed. A single beep
is emitted, indicating that the scan engine has read a Code 128 bar code and the
data has been transferred to the host. If using a Granit scan engine, the scan
engine also vibrates. An IMGBOX command may now be sent from the host to
specify the coordinates of the signature capture area below that code, and indicat-
ing that only that area containing the signature should be transferred as an image
to the host.
To see this example, align the aimer with the signature area (not with the bar code),
then press the trigger.
Send the following IMGBOX command string after the button push:
Example: IMGBOX245w37h55y.
Note: Case is not important in the command string. It is used here only for clarity.
The following image is captured:
