Establishes tangent vector at 'from' point, based on chord length parametrization; and sets flag whether it has been set by user or by smoothing process.
[Visual Basic .NET] Public Sub SetChordLengthTangentAtFrom ( _ ByVal tangent As IPoint, _ ByVal setByUser As Boolean _ )

);
[C++]Parameters
tangenttangent is a parameter of type IPoint
setByUser setByUser is a parameter of type VARIANT_BOOL

Description
Sets the ChordLength Tangent at the From Point of the BezierCurve. The ChordLength Tangent is not the same as the internal Control Points or the Tangent at the From Point although both lie on the same line.
