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.
