Public Function ChangeEndWeights ( 
	w0 As Double,
	w1 As Double
) As Boolean

w0

Type: System.Double
Weight for first control point.

w1

Type: System.Double
Weight for last control point.

Type: Boolean
true on success, false on failure.

The domain, euclidean locations of the control points, and locus of the curve do not change, but the weights, homogeneous cv values and internal knot values may change. If w0 and w1 are 1 and the curve is not rational, the curve is not changed.
