Property Value
This value is of typeScanBitDepthReduction
Explanation
The BitDepthReduction property sets the method used to reduce the bit depth when scanning in 1 bit color. This property is enabled when the UserInterface property is Suppress and the PixelType property is BW. Note: The BitDepthReduction property is disabled when using a digital camera.
When the BitDepthReduction property is Threshold, the Threshold property is enabled (In some scan devices the Brightness property is enabled). When the BitDepthReduction property is Halftone, the HalfTone, Brightness, and Contrast properties are enabled.
To retrieve the value of the BitDepthReduction property that is supported by the scan device, please execute the GetCapabilityEnumToSingle method. In the case where the scan device does not support the BitDepthReduction functionality, but supports either Threshold or HalfTone, then set this property to Threshold or Halftone whichever the case may be.
