OPTIONS

-The optional -weight value must be a positive real number. The default -value is 6.0. +
+
-weight=number +
The distance from the center is weighted by this; a higher number means +the value falls off more quickly as you go away from the center. +

+This must be a positive real number. +

+The default is 6.0. + +

-maxval=maxval + +
The maxval for the PGM kernel. +

Default is 255. + +

This option was new in Netpbm 10.65 (December 2013). Before that, the +maxval is always 255. + + +
