    • Method Detail

      • expand

        public static org.locationtech.jts.geom.Envelope expand​(org.locationtech.jts.geom.Envelope env,
                                                        double distance)
        Expands an Envelope by a given distance. Both positive and negative distances are handled.
        Parameters:
        env - the source envelope
        distance - the distance we want to expand the envelop in all directions
        Returns:
        the expanded envelope

      • translate

        public static void translate​(org.locationtech.jts.geom.Envelope e,
                             org.locationtech.jts.geom.Coordinate displacement)

      • bufferByFraction

        public static org.locationtech.jts.geom.Envelope bufferByFraction​(org.locationtech.jts.geom.Envelope originalEnvelope,
                                                                  double extentFraction)
        Parameters:
        originalEnvelope - the original envelope
        extentFraction - the buffer distance expressed as a fraction of the average envelope extent
        Returns:
        the buffered envelope
