		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const Standard_Boolean	take1 = Standard_True,
		const Standard_Boolean	take2 = Standard_True
	)		const

 Modifies a curve in order to make its bounds confused with <br>
      given points. <br>
      Works only on lines and B-Splines, returns True in this case, <br>
      else returns False. <br>
      For line considers both bounding points, for B-Splines only <br>
      specified. <br>

Warning : Does not check if curve should be reversed

		const Standard_Boolean	take2 = Standard_True
	)		const

 Modifies a curve in order to make its bounds confused with <br>
      given points. <br>
      Works only on lines and B-Splines, returns True in this case, <br>
      else returns False. <br>

For line considers both bounding points, for B-Splines only
specified.

Warning : Does not check if curve should be reversed

Standard_Boolean ShapeConstruct_Curve::AdjustCurveSegment	(	const Handle< Geom_Curve > &	C3D,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const Standard_Real	U1,
		const Standard_Real	U2
	)		const

 Modifies a curve in order to make its bounds confused with <br>
      given points. <br>
      Works only on lines and B-Splines. <br>

For lines works as previous method, B-Splines are segmented
at the given values and then are adjusted to the points.

		const Standard_Real	first,
		const Standard_Real	last,
		const Standard_Real	prec
	)		const

Converts a curve of any type (only part from first to last)
to bspline. The method of conversion depends on the type
of original curve:
BSpline -> C.Segment(first,last)
Bezier and Line -> GeomConvert::CurveToBSplineCurve(C).Segment(first,last)
Conic and Other -> Approx_Curve3d(C[first,last],prec,C1,9,1000)

		const Standard_Real	first,
		const Standard_Real	last,
		const Standard_Real	prec
	)		const

Converts a curve of any type (only part from first to last)
to bspline. The method of conversion depends on the type
of original curve:
BSpline -> C.Segment(first,last)
Bezier and Line -> GeomConvert::CurveToBSplineCurve(C).Segment(first,last)
Conic and Other -> Approx_Curve2d(C[first,last],prec,C1,9,1000)

static Standard_Boolean ShapeConstruct_Curve::FixKnots ( Handle< TColStd_HArray1OfReal > &  knots )

static

static Standard_Boolean ShapeConstruct_Curve::FixKnots ( TColStd_Array1OfReal &  knots )

static

Fix bspline knots to ensure that there is enough
gap between neighbouring values
Returns True if something fixed (by shifting knot)
