The Graphics::DrawCurve method draws a cardinal spline.
Type: const Pen*
Pointer to a pen that is used to draw the cardinal spline.
Type: const Point*
Pointer to an array of Point objects that specify the coordinates that the cardinal spline passes through.
Type: INT
Integer that specifies the number of elements in the points array.
Type: REAL
Real number that specifies how tightly the curve bends through the coordinates of the cardinal spline.
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.
A segment is defined as a curve that connects two consecutive points in the cardinal spline. The ending point of each segment is the starting point for the next.
The following example draws a cardinal spline.
VOID Example_DrawCurve3(HDC hdc)
{
Graphics graphics(hdc);
// Define a Pen object and an array of Point objects.
Pen greenPen(Color::Green, 3);
Point point1(100, 100);
Point point2(200, 50);
Point point3(400, 10);
Point point4(500, 100);
Point curvePoints[4] = {
point1,
point2,
point3,
point4};
Point* pcurvePoints = curvePoints;
// Draw the curve.
graphics.DrawCurve(&greenPen, curvePoints, 4, 1.0);
//Draw the points in the curve.
SolidBrush redBrush(Color::Red);
graphics.FillEllipse(&redBrush, Rect(95, 95, 10, 10));
graphics.FillEllipse(&redBrush, Rect(195, 45, 10, 10));
graphics.FillEllipse(&redBrush, Rect(395, 5, 10, 10));
graphics.FillEllipse(&redBrush, Rect(495, 95, 10, 10));
}
