 Contap_TheIWalking (const Standard_Real Epsilon, const Standard_Real Deflection, const Standard_Real Step, const Standard_Boolean theToFillHoles=Standard_False)
 Deflection is the maximum deflection admitted between two consecutive points on a resulting polyline. Step is the maximum increment admitted between two consecutive points (in 2d space). Epsilon is the tolerance beyond which 2 points are confused. theToFillHoles is the flag defining whether possible holes between resulting curves are filled or not in case of Contap walking theToFillHoles is True.
