W - Target White Value
Sets the target for the median grayscale value in the captured image.  For capturing close-up images of high contrast doc-
uments, a lower setting, such as 75, is recommended.  Higher settings result in longer exposure times and brighter images, 
but if the setting is too high, the image may be overexposed.  Target White Value is only available when using Photo Style 
(1P).  (Default = 125)
nW Range: 0 - 255
D - Delta for Acceptance
This sets the allowable range for the white...

IMGSHP Modifiers
A - Infinity Filter
Enhances pictures taken from very long distances (greater than 10 feet or 3m).  The Infinity Filter should not be used with 
IMGSNP Modifiers (page 9-1).
0A Infinity filter off (default)
1A Infinity filter on
C - Compensation
Flattens the image to account for variations in illumination across the image.
0C Compensation disabled (default)
1C Compensation enabled
D - Pixel Depth
Indicates the number of bits per pixel in the transmitted image (KIM or BMP format...

E - Edge Sharpen
An edge sharpen filter cleans up the edges of an image, making it look cleaner and sharper.  While edge sharpening does 
make the image look cleaner, it also removes some fine detail from the original image.  The strength of the edge sharpen 
filter can be entered from 1 to 24.  Entering a 23E gives the sharpest edges, but also increases noise in the image.
0E Don’t sharpen image (default)
14E Apply edge sharpen for typical image
ne Apply edge sharpen using strength n (n = 1-24)

I - Invert Image
Invert image is used to rotate the image around the X or Y axis.  
1ix Invert around the X axis (flips picture upside down)
1iy Invert around the Y axis (flips picture left to right)
IF- Noise Reduction
Used to reduce the salt and pepper noise in an image.
0if No salt and pepper noise reduction (default)
1if Salt and pepper noise reduction

IR - Image Rotate  
0ir Image as snapped (rightside up) (default)
1ir Rotate image 90 degrees to the right
2ir Rotate image 180 degrees (upside down)
3ir Rotate image 90 degrees to the left
J - JPEG Image Quality
Sets the desired quality when the JPEG image format is selected.  Higher numbers result in higher quality, but larger files.  
Smaller numbers result in greater amounts of lossy compression, faster transmission times, lower quality, but smaller files.  
(Default =  50)

nL The left edge of the shipped image corresponds to column n of the image in memory.  Range: 000 - 843.  (Default 
=  0)
nR The right edge of the shipped image corresponds to column n - 1 of the image in memory.  Range: 000 - 843.  
(Default =  all columns)
nT The top edge of the shipped image corresponds to row n of the image in memory.  Range: 000 - 639.  (Default =  0)
nB The bottom edge of the shipped image corresponds to row n - 1 of the image in memory.  Range: 000 - 639.

3S ship every 3rd pixel, both horizontally and vertically
U - Document Image Filter
Allows you to input parameters to sharpen the edges and smooth the area between the edges of text in an image.  This fil-
ter should be used with gamma correction (see page 9-7), with the scanner in a stand, and the image captured using the 
command:
IMGSNP1P0L168W90%32D
This filter typically provides better JPEG compression than the standard E - Edge Sharpen command (see page 9-9).  This 
filter also works well...

Image Size Compatibility
If you have applications that expect an image ship to return exactly 640x480 pixels, scan the Force VGA Resolution bar 
code.  Default = Native Resolution.
Intelligent Signature Capture - IMGBOX
IMGBOX allows you to configure the size and location of a signature capture area relative to its proximity to a bar code.  This 
allows you to tailor a signature capture area to a specific form.  In order to use IMGBOX, you need a set form where the signa-
ture...

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 scanner has read a Code 128 bar code and the data has 
been transferred to the host.  If using a Granit scanner, the scanner 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 indicating that only that...

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. 
8D 8 bits per pixel, grayscale image  (default)
1D 1 bit per pixel, black and white image
F - File Format
This option indicates the type of file format in which to save the image.  
0F KIM format
1F TIFF binary
2F TIFF...
