NAME

   pnmsmooth - smooth out an image

SYNOPSIS

   pnmsmooth [-size width height] [-dump dumpfile] [pnmfile]

DESCRIPTION

   This program is part of Netpbm.

   pnmsmooth  smoothes	out an image by replacing each pixel with
the average of
   its width X height neighbors. It is implemented  as	a  progam
that generates a
   PGM convolution matrix and then invokes pnmconvol with it.

OPTIONS

   -size width height
	  Specifies  the  size of the convolution matrix. Default
size is a 3x3
	  matrix.  Width  and  height  sizes must be odd. Maximum
size of
	  convolution  matrix is limited by the maximum value for
a pixel such
	  that (width * height * 2) must not exceed  the  maximum
pixel value.
   -dump dumpfile
	  This options makes pnmsmooth only generate and save the
convolution
	  file. It does not invoke pnmconvol and does not produce
an output
	  image.
