+About Bayerscale:
+When bayer dithering is selected, the Bayer Scale option defines the scale of the pattern (how much the
+crosshatch pattern is visible). A low value means more visible pattern for less banding, and higher value
+means less visible pattern at the cost of more banding. The option must be an integer value in the range
+[0,5]. The Default is 2. Bayer Scale is optional.
