R - Resolution of Signature Capture Area
The resolution is the number of pixels that the scan engine 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. Values begin at 1000. The scan engine automatically
inserts a decimal point between the first and second digit. For example, use 2500 to specify 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 7-11).
S - Bar Code Aspect Ratio
All dimensions used in IMGBOX are measured as multiples of the minimum element 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, the narrow ele-
ment 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
The width of the signature capture area must be measured in inches divided by .01. In the example, the width of the area
to be captured is 2.4 inches, resulting in a value of W = 2.4/0.01 = 240. (A value of 245 was used in the example to accom-
modate a slightly wider image area.)
