◆ lwgeom_calculate_gbox()

int lwgeom_calculate_gbox ( const LWGEOM lwgeom,
GBOX gbox 

Calculate the gbox for this goemetry, a cartesian box or geodetic box, depending on how it is flagged.

Calculate bounding box of a geometry, automatically taking into account whether it is cartesian or geodetic.
