IBezierCurve.SetChordLengthTangentAtFrom Method

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#]
public void SetChordLengthTangentAtFrom (
    IPoint tangent,
    bool setByUser
);

[C++]
HRESULT SetChordLengthTangentAtFrom(
  IPoint* tangent,
  VARIANT_BOOL setByUser
);

[C++]
Parameters
tangent 

  tangent is a parameter of type IPoint*
setByUser 

  setByUser is a parameter of type 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.
