Method Detail

scaleGeometry

public static void scaleGeometry(org.locationtech.jts.geom.Geometry geometry,
                                 double scale)

Method to scale a selected geometry of a scale factor

Parameters:

geometry - the geometry to be scaled

scale - the scale factor to apply (50 = half, 100 = no rescale, 200 = scale two times)

rotateGeometry

public static void rotateGeometry(org.locationtech.jts.geom.Geometry geometry,
                                  double angle)

Method to clock wise rotate a geometry of a defined angle

Parameters:

geometry - the geometry to be rotated

angle - in degree

rotateGeometry

public static void rotateGeometry(org.locationtech.jts.geom.Geometry geometry,
                                  int angle)

Method to counterclock wise rotate a geometry of a defined angle

Parameters:

geometry - the geometry to be rotated

angle - in degree

centerGeometry

public static void centerGeometry(org.locationtech.jts.geom.Geometry geometry,
                                  org.locationtech.jts.geom.Coordinate displacement)

Move a geometry to a defined coordinate

Parameters:

geometry - the geometry to be moved

displacement - the new geometry coordinate

createEmptyGeometry

public static org.locationtech.jts.geom.Geometry createEmptyGeometry(Class geometryClass,
                                                                     org.locationtech.jts.geom.GeometryFactory geometryFactory)

creates an empty geometry matching the geom type set already or an empty geom collection if that fails

Parameters:

geometryClass - the geometry Class

geometryFactory - the GeometryFactory to create the empty Geometry

Returns:

an empty Geometry of the specified class
