NAME
       pnmsmooth - smooth out an image

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

DESCRIPTION
       Smooths	out  an	 image by replacing each pixel with the average of its
       width X height neighbors.  It is implemented as a C progam that	generÔÇÉ
       ates a PGM convolution matrix and then invokes pnmconvol.

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
	      Generates	 and  saves  the  convolution  file only.  Use of this
	      option does not invoke pnmconvol.
