K - Gamma Correction
Gamma measures the brightness of midtone values produced by the image. You 
can brighten or darken an image using gamma correction. A higher gamma correc-
tion yields an overall brighter image. The lower the setting, the darker the image. 
The optimal setting for text images is 50K. 
0K Gamma correction off (default)
50K Apply gamma correction for brightening typical document image
nK Apply gamma correction factor n (n = 0-1,000)
Example:
L, R, T, B, M -...

252 Xenon/Granit User GuidenB The bottom edge of the shipped image corresponds to row n - 1 of the 
image in memory. Range: 000 - 639. (Default = all rows)
Example:
Alternately, specify the number of pixels to cut from the outside margin of the 
image; thus only the center pixels are transmitted.
nM Margin: cut n columns from the left, n + 1 columns from the right, n rows 
from the top, and n + 1 rows from the bottom of the image. Ship the 
remaining center pixels. Range: 0 - 238. 
(Default = 0, or full...

Xenon/Granit User Guide 253The smaller number of pixels shipped, the smaller the image, however, after a cer-
tain point the image becomes unusable. 
1S ship every pixel (default)
2S ship every 2nd pixel, both horizontally and vertically
3S ship every 3rd pixel, both horizontally and vertically
Example:
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 filter should be used with gamma correction 
(see page 251),...

V - Blur Image
Smooths transitions by averaging the pixels next to the hard edges of defined lines 
and shaded areas in an image. 
0V Don’t blur (default)
1V Blur
Example:
W - Histogram Ship
A histogram gives a quick picture of the tonal range of an image, or key type. A low-
key image has detail concentrated in the shadows; a high-key image has detail 
concentrated in the highlights; and an average-key image has detail concentrated 
in the midtones. This modifier ships the...

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 sig-
nature box location is in a known location relative to a bar code. You can input the 
overall size of the signature area, as well as specify how far the signature area is 
from the bar...

256 Xenon/Granit User GuideTo 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 trigger press:
Example: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 scanner. Modifiers...

B - Output Image Height   
This option is used to size the image vertically. If using this option, set the resolu-
tion (R) to zero.
Example:
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.

H - Height of Signature Capture Area
The height of the signature capture area must be measured in inches divided by 
.01. In the example, the height of the area to be captured is 3/8 inch, resulting in a 
value of H = .375/0.01 = 37.5. 
K - Gamma Correction
Gamma measures the brightness of midtone values produced by the image. You 
can brighten or darken an image using gamma correction. A higher gamma correc-
tion yields an overall brighter image. The lower the setting, the...

a resolution of 2.5. Set to zero when using the A and B modifiers (see A - Output 
Image Width and B - Output Image Height on page 257).
Example:
S - Bar Code Aspect Ratio
All dimensions used in IMGBOX are measured as multiples of the minimum ele-
ment size of the bar code. The bar code aspect ratio allows you to set the ratio of 
the bar code height to the narrow element width. In the example,...

Y - Vertical Bar Code Offset
The vertical bar code offset allows you to offset the vertical center of the signature 
capture area. Negative numbers indicate that the signature capture is above the 
bar code, and positive numbers indicate that the area is below the bar code. Mea-
surements are in multiples of the minimum bar width
Example:.
