Remarks
The ThresholdColor property defines the color of the pixels whose gray values are between the ThresholdHigh and ThresholdLow properties during binarization. For example, when ThresholdColor = Black, ThresholdLow = 50 and ThresholdHigh = 100, then pixels whose gray values are between 50 and 100 will be set to black during binarization. All other pixels will be white.
