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 rela-
       tive 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 ).
