pgmkernel

Generate a convolution kernel to be used with pnmconvol. See also: pnmconvol. More information: https://netpbm.sourceforge.net/doc/pgmkernel.html.

  • Generate a convolution kernel:

pgmkernel {{width}} {{height}} > {{path/to/output.pgm}}

  • Generate a quadratic convolution kernel:

pgmkernel {{size}} > {{path/to/output.pgm}}

  • Specify the weight of the center in the generated kernel:

pgmkernel -weight {{value}} {{width}} {{height}} > {{path/to/output.pgm}}
