pgmbentley - Bentleyize a PGM image

pgmbentley [pgmfile]

This program is part of Netpbm(1)

pgmbentley reads a PGM image as input and performs the Bentley Effect, and writes a PGM image as output.

The Bentley Effect is described in 'Beyond Photography' by Holzmann, chapter 4, photo 4. It's a vertical smearing based on brightness.
