- .IX pnmsmooth
- .SH NAME
- pnmsmooth - smooth out an image
- .SH SYNOPSIS
- .B pnmsmooth
-+.RB [ -size
-+.IR width
-+.IR height ]
-+.RB [ -dump
-+.IR dumpfile ]
- .RI [ pnmfile ]
- .SH DESCRIPTION
- Smooths out an image by replacing each pixel with the
--average of its nine immediate neighbors.
-+average of its width X height neighbors.
- .IX smoothing
- .IX anti-aliasing
--It is implemented as a simple script using
-+It is implemented as a C progam that generates a PGM convolution matrix
-+and then invokes
- .IR pnmconvol .
- .IX pnmconvol
-+.SH OPTIONS
-+.TP
-+.B -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.
-+.TP
-+.B -dump dumpfile
-+Generates and saves the convolution file only.
-+Use of this option does not invoke pnmconvol.
- .SH "SEE ALSO"
- pnmconvol(1), pnm(5)
