Example
[Visual Basic, C#] The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:
- Creates a black pen.
- Creates the position and size of a rectangle to bound an ellipse.
- Defines the start (45 degrees) and sweep (270 degrees) angles.
- Draws the elliptical arc to the screen.
[Visual Basic, C#] The result is a partial ellipse missing a segment between + and - 45 degrees of the x axis.
[Visual Basic, C#] Note This example shows how to use one of the overloaded versions of DrawArc. For other examples that might be available, see the individual overload topics.
[Visual Basic] Public Sub DrawArcFloat(e As PaintEventArgs) ' Create pen. Dim blackPen As New Pen(Color.Black, 3) ' Create coordinates of rectangle to bound ellipse. Dim x As Single = 0F Dim y As Single = 0F Dim width As Single = 100F Dim height As Single = 200F ' Create start and sweep angles on ellipse. Dim startAngle As Single = 45F Dim sweepAngle As Single = 270F ' Draw arc to screen. e.Graphics.DrawArc(blackPen, x, y, width, height, startAngle, _ sweepAngle) End Sub [C#] public void DrawArcFloat(PaintEventArgs e) { // Create pen. Pen blackPen= new Pen(Color.Black, 3); // Create coordinates of rectangle to bound ellipse. float x = 0.0F; float y = 0.0F; float width = 100.0F; float height = 200.0F; // Create start and sweep angles on ellipse. float startAngle = 45.0F; float sweepAngle = 270.0F; // Draw arc to screen. e.Graphics.DrawArc(blackPen, x, y, width, height, startAngle, sweepAngle); }
