GraphicsPath.AddClosedCurve(const Point*, INT) method

Applies to: desktop apps only

The GraphicsPath::AddClosedCurve method adds a closed cardinal spline to this path.

Syntax

Status AddClosedCurve(
  [in]  const Point *points,
  [in]  INT count
);

Parameters

  • points [in]
    Type: const Point*

    Pointer to an array of points that define the cardinal spline. The cardinal spline is a curve that passes through each point in the array.

  • count [in]
    Type: INT

    Integer that specifies the number of elements in the points array.

Return value

Type:

Type: Status****

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.

Remarks

You should keep a copy of the points array if those points will be needed later. The GraphicsPath object does not store the points passed to the GraphicsPath::AddClosedCurve method; instead, it converts the cardinal spline to a sequence of Bézier splines and stores the points that define those Bézier splines. You cannot retrieve the original array of points from the GraphicsPath object.

Examples

The following example creates a GraphicsPath object path, adds a closed cardinal spline to path, and then draws path.

VOID Example_AddClosedCurve(HDC hdc)
{
   Graphics graphics(hdc); 

   Point pts[] = {Point(50,50),
                  Point(60,20),
                  Point(70,100),
                  Point(80,50)};

   GraphicsPath path;
   path.AddClosedCurve(pts, 4);

   // Draw the path.
   Pen pen(Color(255, 255, 0, 0));
   graphics.DrawPath(&pen, &path);
}
