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
n K 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. For example, use 2500 to specify a resolution of 2.5. Set to zero
Example: IMGBOX245w 37h 55y.
