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 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 maximum pixel value.

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