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 random 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).

       The randomness in the image is limited before Netpbm 10.37 (December 2006) -- if  you  run
       the program twice in the same second, you may get identical output.
