Let r.grow shrink raster
|Reported by:||cmbarton||Owned by:|
Grass can grow a raster, but there is no way to shrink a raster except to completely thin it. If r.grow could accept values less than 1.0, this could be accomplished.
That is, if you put in a value of 0.8, the raster would shrink by 20%. Is this feasible given the code of r.grow?
