Chapter 11 Raster Manipulation

The fill_holes command will evaluate the current raster and turn on any single
off pixel which is surrounded on four sides by on pixels.  This single off
pixel is known as a hole.  The raster need not be assembled.  The inverse of
fill_holes is del_points.

fill_holes

    Fills all single-pixel holes in the raster.

         fill_holes

    Fills all single-pixel holes within the raster (inverse of del_points).
    Assembly is not required.
