NAME
       ppmspread - displace a portable pixmap's pixels by a random amount

SYNOPSIS
       ppmspread amount [ppmfile]

DESCRIPTION
       Reads  a portable pixmap as input. 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  pro-
       cessed by something like pnmconvol ).
