Performs a Maximum filter (Dilate Filter)of any size of kernel (amount of pixels included in operation) on a GdPicture image or on an area of a GdPicture image defined by SetROI() method. It selects the Maximum value or the neighboring pixels to each pixel and gives it that value. Basically, in binary images, it makes objects in the become smaller, and in colored images it makes the image brighter because the darker objects shrink.
