Imaging Commands
The document reader is like a digital camera in the way it captures, manipulates, and transfers images. The following com-
mands allow you to alter the way the document reader performs these functions.
Single-Use Basis
Imaging Commands with their modifiers send instructions to the document reader on a single-use basis, and take effect for a
single image capture. Once that capture is complete, the document reader reverts to its imaging default settings. If you want to
permanently change a setting, you must use the serial default commands (see
Chapter 2 ). When the serial default command is
used, that selection becomes the new, permanent setting for the document reader.
Command Syntax
Multiple modifiers and commands can be issued within one sequence. If additional modifiers are to be applied to the same
command, just add the modifiers to that command. For example, to add 2 modifiers to the Image Snap command, such as set-
ting the Imaging Style to 1P and the Wait for Trigger to 1T, you would enter
IMGSNP1P1T.
Note: After processing an image capture command (IMGSNP or IMGBOX), you must follow it with an IMGSHP or IMGACP
command if you want to see it on your terminal.
To add a command to a sequence, each new command is separated with a semicolon. For example, to add the Image Ship
command to the above sequence, you would enter IMGSNP1P1T;IMGSHP.
The imaging commands are:
Image Snap - IMGSNP (page 1-1)
Image Ship - IMGSHP (page 1-4)
Intelligent Signature Capture - IMGBOX (page 1-12)
The modifiers for each of these commands follow the command description.
Note: The images included with each command description are examples only. The results you achieve may be different from
those included in this manual. The quality of the output you receive will vary depending on lighting and the quality of the
initial image/object being captured.
Step 1 - Take a Picture Using IMGSNP
Image Snap - IMGSNP
An image is taken whenever the hardware button is pressed, or when the Image Snap (IMGSNP) command is processed.
The image snap command has many different modifiers that can be used to change the look of the image in memory. Any
number of modifiers may be appended to the IMGSNP command. For example, you can use the following command to
snap an image, increase the gain, and have the beeper sound once the snap is complete.
IMGSNP Modifiers
P - Imaging Style
This sets the Image Snap style.
0P Decoding Style . This processing allows a few frames to be taken until the exposure parameters are met. The last
frame is then available for further use.
1P Photo Style (default) . This mimics a simple digital camera, and results in a visually optimized image.
2P Manual Style . This is an advanced style that should only be used by an experienced user. It allows you the most
freedom to set up the scanner, and has no auto-exposure.
B - Beeper
Causes a beep to sound after an image is snapped.
0B No beep (default)
1B Sounds a beep when the image is captured.
