AutoColorLevelCommand Constructor(Int32,Int32,AutoColorLevelCommandType,AutoColorLevelCommandFlags)

Show in webframe
Example 







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.
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.
Value that indicates the type of leveling to perform.
Flag that indicates whether the method will process the image or not.
Initializes a new AutoColorLevelCommand object with explicit parameters.
