image
RasterImage object that references the image to be modified.
region
LEADTOOLS RasterRegion representing the dot to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.
boundingRectangle
The bounding rectangle of the dot being processed.
whiteCount
Total number of white pixels in the dot being processed.
blackCount
Total number of black pixels in the dot being processed.
Run the DotRemoveCommand on an image.
