ppmspread(1) AMIGA (16 November 1993) ppmspread(1)
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 processed by something like pnmconvol ).

ppm(5), pnmconvol(1)
