Performs a Minimum filter (Erode 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 Minimum value or the neighboring pixels to each pixel and gives it that value. Basically, in binary images, it makes objects in the image grow larger, and in colored images it makes the image darker because the darker objects grow.
