NAME

       pamoil - turn a PAM image into an oil painting

SYNOPSIS

       pamoil [-n N] [pamfile]

DESCRIPTION

       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.

OPTIONS

       -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.
