example, the height of the area to be captured is 1 inch, resulting in
a value of H = 1/0.01 = 100. The value for H is slightly larger, to
accommodate some extra image capture area outside of the
signature capture box.
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
correction yields an overall brighter image. The lower the setting,
the darker the image. A setting of 100 results in no adjustment to
the image. (Default = 50K)
0K Gamma correction off
50K Apply gamma correction for brightening typical document

nK Apply gamma correction factor n (n = 1-255)
R - Resolution of Signature Capture Area: The number of
pixels that the imager outputs per each minimum bar width. The
higher the value for R, the higher the quality of the image, but also
the larger the file size.
S - Bar Code Aspect Ratio: The ratio of the bar code height to the
narrow element width. In the example, the narrow element width
is .010 inches and the bar code height is 0.400 inches, resulting in
a value of S = 0.4/0.01 = 40.
W - Width of Signature Capture Area: In the example, the
width of the area to be captured is 1.90 inches, resulting in a value
of W = 1.9/0.01 = 190. The value for W is slightly larger, to
accommodate some extra image capture area outside of the
signature capture box.
X - Horizontal Bar Code Offset: The horizontal ratio offset of
the center of the signature capture area, in multiples of the
minimum bar width. In the example, the horizontal offset is 0.
Y - Vertical Bar Code Offset: The vertical offset of the center of
the signature capture area, in multiples of the minimum bar width.
Negative numbers indicate that the signature capture is above the
bar code, and positive numbers indicate that the area is below the
bar code. In the example, the horizontal offset is 0.70 inches,
resulting in a value for Y = 0.7/0.01 = 70.
