Method Detail

expand

public static com.vividsolutions.jts.geom.Envelope expand(com.vividsolutions.jts.geom.Envelope env,
                                          double distance)

Expands an Envelope by a given distance. Both positive and negative distances are handled.

translate

public static void translate(com.vividsolutions.jts.geom.Envelope e,
             com.vividsolutions.jts.geom.Coordinate displacement)

bufferByFraction

public static com.vividsolutions.jts.geom.Envelope bufferByFraction(com.vividsolutions.jts.geom.Envelope originalEnvelope,
                                                    double extentFraction)

Parameters:

originalEnvelope - the original envelope

extentFraction - the buffer distance expressed as a fraction of the average envelope extent

centre
