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.
