D - Pixel Depth: Indicates the number of bits per pixel in the transmitted image.
•
8D 8 bits per pixel, grayscale image
•
1D 1 bit per pixel, black and white image
F - File Format: Indicates the type of file format in which to save the image.
•
0F
KIM format
•
1F
TIFF binary
•
2F
TIFF binary group 4, compressed
•
3F
TIFF grayscale
•
4F
Uncompressed Binary
•
5F
Uncompressed grayscale
•
6F
JPEG image (default)

8F BMP format
H - Height of Signature Capture Area: In the 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 image
•
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.
