This property sets the scanning threshold. This property is only enabled when using a custom-built user interface (UserInterface=Suppress).
Property Value
From 0 to 255 (Default value is 128)
Explanation
The Threshold property sets the scanning threshold. This property is only enabled when the UserInterface property is Suppress.
The Threshold property requires that the PixelType property be BW and the BitDepthReduction property be Threshold. For scan devices that use brightness instead of threshold, the Brightness property value will be used.
Note: This property is disabled for digital cameras and scanners that do not support this function. The possible setting values supported by a scan device can be retrieved using the GetCapabilityEnumToSingle or the GetCapabilityRange method.
