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.
