Method
Definition
Adds a closed curve to this path. A cardinal spline curve is used because the curve travels through each of the points in the array.

public:
void AddClosedCurve(cli::array <System::Drawing::Point> ^ points);

Public Sub AddClosedCurve (points As Point())
Parameters
Examples
For an example, see AddClosedCurve(Point[], Single).
Remarks
The user must keep the original points if they are needed. The original points are converted to cubic Bézier control points internally, therefore there is no mechanism for returning the original points. If the first point and the last point in the points
array are not the same point, the curve is closed by connecting these two points. The tension value cannot be set for this method, and defaults to a value equivalent to 0.5.

void AddClosedCurve(cli::array <System::Drawing::Point> ^ points, float tension);
public void AddClosedCurve (System.Drawing.Point[] points, float tension);
member this.AddClosedCurve : System.Drawing.Point[] * single -> unit
Public Sub AddClosedCurve (points As Point(), tension As Single)
Parameters
A value between from 0 through 1 that specifies the amount that the curve bends between points, with 0 being the smallest curve (sharpest corner) and 1 being the smoothest curve.
Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgse
, an OnPaint event object. The code performs the following actions:
Creates an array of six points (representing a cardinal spline).
Creates a path and adds the closed cardinal spline curves to the path (closed from the endpoint to the starting point).
Draws the path to screen.
Notice that a tension of 0.5 is used.
