ppmspread (1)
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
).
