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.
