FxDespeckle Method (GdPictureImaging)

Performs a 3x3 despeckle filter (also known as median filter) on a GdPicture image or on an area of a GdPicture image defined by SetROI() method. It works as a noise removal filter, for Salt-And-Pepper like-noise, or varied dots around a document. It can remove black noise pixels from white backgrounds and visa versa. It also can remove random noise from multicolored backgrounds.
