Explanation
The ColorBWRatio property is useful in determining whether or not to scan in RGB color or black and white. This property sets the allowable ratio of color pixels in a document for the scanner to scan in black and white. Beyond this value, the scanner will scan in rgb color. This property is only enabled when using a custom-built user interface (UserInterface=Suppress).
ENABLED FOR PANASONIC SCAN DRIVERS ONLY
The default value is one, meaning that the scanner will scan in rgb color. The allowable range that can be set in the ColorBWRatio property is from 0.01 to 50.00 percent. As the value of this property increases, a larger proportion of pixels in the document must be color before the scanner will scan in rgb color. This property is only enabled when the UserInterface property is Suppress, and the PixelType property is Automation.
