B - Output Image Height
This option is used to size the image vertically. If using this option, set the resolution (R) to zero.
D - Pixel Depth
This indicates the number of bits per pixel in the transmitted image, which defines whether it will be grayscale or black and
white.
8D 8 bits per pixel, grayscale image (default)
1D 1 bit per pixel, black and white image
F - File Format
This option indicates the type of file format in which to save the image.
0F KIM format
1F TIFF binary
2F TIFF binary group 4, compressed
3F TIFF grayscale
4F Uncompressed Binary
5F Uncompressed grayscale
6F JPEG image (default)
7F Outlined image
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.
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)
