lwcurve_linearize()

LWGEOM * lwcurve_linearize ( const LWGEOM *  geom, double  tol, LW_LINEARIZE_TOLERANCE_TYPE  type, int  flags  )

extern

Parameters

geom	input geometry
tol	tolerance, semantic driven by tolerance_type
type	see LW_LINEARIZE_TOLERANCE_TYPE
flags	bitwise OR of operational flags, see LW_LINEARIZE_FLAGS

Returns
