Voronoj Diagram

\param geom pointer to input Geometry object. \param extra_frame_size percent factor expanding the BBOX of input Geometry \param tolerance optional snapping tolerance. \param only_edges if non-zero will return a MULTILINESTRING, otherwise it will return a MULTIPOLYGON.

\return the pointer to newly created Geometry object: NULL on failure. \n NULL will be returned if any argument is invalid.

\sa gaiaVoronojDiagram_r, gaiaFreeGeomColl, gaiaDelaunayTriangulation

\note you are responsible to destroy (before or after) any allocated Geometry, this including any Geometry returned by gaiaVoronojDiagram()\n not reentrant and thread unsafe.

\remark \b GEOS-TRUNK support required.
