NAME
pgmkernel - generate a convolution kernel
SYNOPSIS
pgmkernel [ -weight w ] width [ height ]
DESCRIPTION
Generates a portable graymap array of size width x height (or width x width if height is
not specified) to be used as a convolution file by pnmconvol. The data in the convolution
array K are computed according to the formula:
K(i,j) = 1 / ( 1 + w * sqrt((i-width/2)^2 + (j-height/2)^2))
where w is a coefficient specified via the -weight flag, and width and height are the X
and Y filter sizes.
The output PGM file is always written out in ASCII format.
OPTIONS
The optional -weight flag should be a real number greater than -1. The default value is
6.0.
