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.
