NAME
pnmsmooth - smooth out an image
SYNOPSIS
pnmsmooth
[-size width height]
[-dump
dumpfile]
[pnmfile]
DESCRIPTION
This program is part of Netpbm.
pnmsmooth smoothes out an image by replacing each pixel with
the average of its width X height neighbors. It is implemented as a
progam that generates a PGM convolution matrix and then invokes
pnmconvol with it.
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
- This options makes pnmsmooth only generate and save the
convolution file. It does not invoke pnmconvol and does not
produce an output image.
