PROGRAM:
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.
