NAME

ppmrelief - compute a relief of a PPM image

 

SYNOPSIS

ppmrelief

[ppmfile]

 

DESCRIPTION

This program is part of Netpbm(1).

ppmrelief reads a PPM image as input, and writes a relief of that image as a PPM image as output.

The relief process is described in "Beyond Photography" by Holzmann, equation 3.19. It's a sort of edge-detection and is essentially a convolution with this matrix:


    |  1  0  0 |
    |  0  0  0 |
    |  0  0 -1 |
