NAME
pnmsmooth - smooth out an imageSYNOPSIS
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.
