!!DESCRIPTION

The oil transfer is described in


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.
