Graphics.DrawCurve Method (Pen, PointF, Single)
Draws a cardinal spline through a specified array of PointF structures using a specified tension.
Assembly: System.Drawing (in System.Drawing.dll)
- Type: System.Drawing.PointF
Array of PointF structures that represent the points that define the curve.
- Type: System.Single
Value greater than or equal to 0.0F that specifies the tension of the curve.
pen is a null reference (Nothing in Visual Basic).
points is a null reference (Nothing in Visual Basic).
This method draws a cardinal spline that passes through each point in the array.
The array of points must contain at least three PointF structures for a curve to be drawn.
The tension parameter determines the shape of the spline. If the value of the tension parameter is 0.0F, this method draws straight line segments to connect the points. Usually, the tension parameter is less than or equal to 1.0F. Values over 1.0F produce unusual results.
Creates red and green pens.
Creates seven points to define the curve.
Draws six red straight lines between the seven points to form an incomplete polygon.
Creates a tension setting.
Draws an open green closed curve through the seven points.
The method uses a tension of 1.0.
