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 nar-
row 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 sig-
nature 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.
