H - Height of Signature Capture Area
The height of the signature capture area must be measured in inches divided
by .01. In the example, the height of the area to be captured is 3/8 inch,
resulting in a value of H = .375/0.01 = 37.5.
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. The optimal setting for text images is 50K.
