Honeywell 1900, 1902 37h, K - Gamma Correction, Example: IMGBOX245w37h55y, H - Height of Signature Capture Area, R - Resolution of Signature Capture Area

8F BMP format

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.

Example: IMGBOX245w37h55y.

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.

0K Gamma correction off (default)

50K Apply gamma correction for brightening typical document image

nK Apply gamma correction factor n (n = 1-255)

R - Resolution of Signature Capture Area

The resolution is the number of pixels that the scanner 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 scanner automatically inserts a decimal point between the first and second digit.
