1 - 16 Document Reader Imaging Guide
R - Resolution of Signature Capture Area
The resolution is the number of pixels that the document reader 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 document reader
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 1-15).
S - Barcode Aspect Ratio
All dimensions used in IMGBOX are measured as multiples of the minimum element size of the barcode. The barcode
aspect ratio allows you to set the ratio of the barcode height to the narrow element width. In the example, the narrow element
width is .010 inches and the barcode 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
accommodate a slightly wider image area.)
X - Horizontal Barcode Offset
The horizontal barcode offset allows you to offset the horizontal center of the signature capture area. Positive values move
the horizontal center to the right and negative values to the left. Measurements are in multiples of the minimum bar width.
Y - Vertical Barcode Offset
The vertical barcode offset allows you to offset the vertical center of the signature capture area. Negative numbers indicate
that the signature capture is above the barcode, and positive numbers indicate that the area is below the barcode.
Measurements are in multiples of the minimum bar width.
