pamoil(1) General Commands Manual pamoil(1)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.
