       pamoil - turn a PAM image into an oil painting

       pamoil [-n N] [pamfile]

       Reads  a Netpbm image as input.  Does an "oil transfer", and writes the
       same type of Netpbm image as output.

       The oil transfer is described  in  "Beyond  Photography"  by  Holzmann,
       chapter 4, photo 7.  It's a sort of localized smearing.

       The  smearing  works  like  this: First, assume a grayscale image.  For
       each pixel in the image, pamoil looks at a square  neighborhood  around
       it.   pamoil  determines what is the most common pixel intensity in the
       neighborhood, and puts a pixel of that intensity into the output in the
       same position as the input pixel.

       For color images, or any arbitrary multi-channel image, pamoil computes
       each channel (e.g. red, green, and blue) separately the same way as the
       grayscale case above.

       At the edges of the image, where the regular neighborhood would run off
       the edge of the image, pamoil uses a clipped neighborhood.

       -n size
              This is the size of the neighborhood used in the smearing.   The
              neighborhood is this many pixels in all four directions.

              The default is 3.
