NAME

       ppmspread - displace a PPM image’s pixels by a random amount

SYNOPSIS

       ppmspread

       amount

       [ppmfile]

DESCRIPTION

       This program is part of Netpbm(1).

       ppmspread reads a PPM image as input and moves every pixel around a bit
       relative to its original position. amount determines by how many pixels
       a pixel is to be moved around at most.

       Pictures  processed with this filter will seem to be somewhat dissolved
       or unfocussed (although they appear more coarse than  images  processed
       by something like pnmconvol).
