blackClip
Value that represents the percentage of black pixels to clip from the image, in hundredths of a percent. Valid values range from 0 to 10000 (which represents 100). Best results are found using 0.3 to 0.9 . The default is 50, which indicates to clip 0.5 of the black pixels.
whiteClip
Value that represents the percentage of white pixels to clip from the image, in hundredths of a percent. Valid values range from 0 to 10000 (which represents 100). The default is 50, which indicates to clip 0.5 of the white pixels.
type
Value that indicates the type of leveling to perform.
flag
Flag that indicates whether the method will process the image or not.
