 Extrema_ExtElC2d ()
 Extrema_ExtElC2d (const gp_Lin2d &C1, const gp_Lin2d &C2, const Standard_Real AngTol)
 Calculates the distance between two lines.
AngTol is used to test if the lines are parallel:
Angle(C1,C2) < AngTol.

 Extrema_ExtElC2d (const gp_Lin2d &C1, const gp_Circ2d &C2, const Standard_Real Tol)
 Calculates the distance between a line and a
circle.

 Extrema_ExtElC2d (const gp_Lin2d &C1, const gp_Elips2d &C2)
 Calculates the distance between a line and an
elipse.

 Extrema_ExtElC2d (const gp_Lin2d &C1, const gp_Hypr2d &C2)
 Calculates the distance between a line and a
hyperbola.

 Extrema_ExtElC2d (const gp_Lin2d &C1, const gp_Parab2d &C2)
 Calculates the distance between a line and a
parabola.

 Extrema_ExtElC2d (const gp_Circ2d &C1, const gp_Circ2d &C2)
 Calculates the distance between two circles.
The circles can be parallel or identical.

 Extrema_ExtElC2d (const gp_Circ2d &C1, const gp_Elips2d &C2)
 Calculates the distance between a circle and an
elipse.

 Extrema_ExtElC2d (const gp_Circ2d &C1, const gp_Hypr2d &C2)
 Calculates the distance between a circle and a
hyperbola.

 Extrema_ExtElC2d (const gp_Circ2d &C1, const gp_Parab2d &C2)
 Calculates the distance between a circle and a
parabola.

 Extrema_ExtElC2d (const gp_Elips2d &C1, const gp_Elips2d &C2)
 Calculates the distance between two elipses.
The elipses can be parallel or identical.

 Extrema_ExtElC2d (const gp_Elips2d &C1, const gp_Hypr2d &C2)
 Calculates the distance between an elipse and a
hyperbola.

 Extrema_ExtElC2d (const gp_Elips2d &C1, const gp_Parab2d &C2)
 Calculates the distance between an elipse and a
parabola.

 Extrema_ExtElC2d (const gp_Hypr2d &C1, const gp_Hypr2d &C2)
 Calculates the distance between two hyperbolas.
The hyperbolas can be parallel or identical.

 Extrema_ExtElC2d (const gp_Hypr2d &C1, const gp_Parab2d &C2)
 Calculates the distance between a hyperbola and a
parabola.

 Extrema_ExtElC2d (const gp_Parab2d &C1, const gp_Parab2d &C2)
 Calculates the distance between two parabolas
The parabolas can be parallel or identical.

Standard_Boolean IsDone () const
 Returns True if the distances are found.

Standard_Boolean IsParallel () const
 Returns True if the two curves are parallel.

Standard_Integer NbExt () const
 Returns the number of extremum distances.

Standard_Real SquareDistance (const Standard_Integer N=1) const
 Returns the value of the Nth extremum square distance.

void Points (const Standard_Integer N, Extrema_POnCurv2d &P1, Extrema_POnCurv2d &P2) const
 Returns the points of the Nth extremum distance.
P1 is on the first curve, P2 on the second one.
