the signature area is from the barcode, vertically and horizontally. You can also
set the resolution and file format for the final output of the signature capture
image.
Note: IMGBOX commands can only be triggered by one of the following types of
barcodes: PDF417, Code 39, Code 128, Aztec, Codabar, and Interleaved
2 of 5. Once one of these symbologies has been read, the image is
retained for a possible IMGBOX command.
The following IMGBOX example was executed and viewed using QuickView
software. This software is available at
www.honeywell.com/aidc . Click on Soft-
ware Downloads . Select 4820 from the Products list, then select QuickView
Software Utility .
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 imager has read a Code 128 barcode
and the data has been transferred to the host. An IMGBOX command may now
be sent from the host to specify the coordinates of the signature capture area
below that code, and indicating 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:
IMGBOX245w37h55y.
Note: Case is not important in the command string. It is used here only for clarity.
The following image is captured:
The IMGBOX commands have many different modifiers that can be used to
change the size and appearance of the signature image output by the imager.
Modifiers affect the image that is transmitted, but do not affect the image in
memory. Modifiers always begin with a number and end with a letter (case
insensitive). Any number of modifiers may be appended to the IMGBOX com-
mand.
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 8-
18) and W - Width of Signature Capture Area (page 8-19).
