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 neigh-
       bors.  It is implemented as a C progam that generates 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 maxi-
              mum pixel value.

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