Creates a box of a user-defined size around each pixel, sorts all of the pixels in that box into a list in order of intensity,
selects a pixel at a user-defined position in that list and replaces the initial pixel with that color. Useful for shrinking
or growing images or masks, stripping out areas of extreme high or low intensity, and creating artistic effects. The Rank
filter includes all of the functionality of the Median and Min Max Filters, and additionally allows other levels to be emphasized.

Sets the position or rank in the list of sorted pixels at which the pixel value will be selected. Set a value between 0 and

1.0 produces a maximum filter (dilate).
