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.
