Method Detail

execute

public static com.vividsolutions.jts.geom.Geometry execute(com.vividsolutions.jts.geom.Geometry geom,
                                                           double theta)

Rotates a geometry by a given angle (in radians) about the center of the geometry's envelope.

Parameters:

geom - Geometry

theta - Angle

Returns:

The geometry rotated about the center of its envelope

execute

public static com.vividsolutions.jts.geom.Geometry execute(com.vividsolutions.jts.geom.Geometry geom,
                                                           double theta,
