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.
