!!DESCRIPTION |

|

|
| |
|
22 |
Smooths out an image by replacing each pixel with the |
| |
|
23 |
average of its width X height neighbors. It is implemented |
| |
|
24 |
as a C progam that generates a PGM convolution matrix and |
| |
|
25 |
then invokes ''pnmconvol''. |

__-size width height__ |
| |
|
30 |
|
| |
|
31 |
|
| |
|
32 |
Specifies the size of the convolution matrix. Default size |
| |
|
33 |
is a 3x3 matrix. Width and height sizes must be odd. Maximum |
| |
|
34 |
size of convolution matrix is limited by the maximum value |
| |
|
35 |
for a pixel such that (width * height * 2) must not exceed |
| |
|
36 |
the maximum pixel value. |

__-dump dumpfile__ |
| |
|
40 |
|
| |
|
41 |
|
| |
|
42 |
Generates and saves the convolution file only. Use of this |
| |
|
43 |
option does not invoke pnmconvol. |
