Class OffsetPointGenerator

  • public class OffsetPointGenerator
extends java.lang.Object
    Generates points offset by a given distance from both sides of the midpoint of all segments in a Geometry. Can be used to generate probe points for determining whether a polygonal overlay result is incorrect. The input geometry may have any orientation for its rings, but setSidesToGenerate(boolean, boolean) is only meaningful if the orientation is known.
