Public Sub FillPie (brush As Brush, rect As Rectangle, startAngle As Single, sweepAngle As Single)

brush

Brush

Brush that determines the characteristics of the fill.

rect

Rectangle

Rectangle structure that represents the bounding rectangle that defines the ellipse from which the pie section comes.

startAngle

Single

Angle in degrees measured clockwise from the x-axis to the first side of the pie section.

sweepAngle

Single

Angle in degrees measured clockwise from the startAngle parameter to the second side of the pie section.

Exceptions

ArgumentNullException

Examples

The following code 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 solid red brush.

• Creates a rectangle that bounds an ellipse.

• Defines the start angle (relative to the x axis) and the sweep angle (both in a clockwise direction).

• Fills the pie-shaped area of the ellipse on the screen.

public:
   void FillPieRectangle( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );

      // Create rectangle for ellipse.
      Rectangle rect = Rectangle(0,0,200,100);

      // Create start and sweep angles.
      float startAngle = 0.0F;
      float sweepAngle = 45.0F;

      // Fill pie to screen.
      e->Graphics->FillPie( redBrush, rect, startAngle, sweepAngle );
   }

public void FillPieRectangle(PaintEventArgs e)
{
             
    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);
             
    // Create rectangle for ellipse.
    Rectangle rect = new Rectangle(0, 0, 200, 100);
             
    // Create start and sweep angles.
    float startAngle =  0.0F;
    float sweepAngle = 45.0F;
             
    // Fill pie to screen.
    e.Graphics.FillPie(redBrush, rect, startAngle, sweepAngle);
}

Public Sub FillPieRectangle(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim redBrush As New SolidBrush(Color.Red)

    ' Create rectangle for ellipse.
    Dim rect As New Rectangle(0, 0, 200, 100)

    ' Create start and sweep angles.
    Dim startAngle As Single = 0.0F
    Dim sweepAngle As Single = 45.0F

    ' Fill pie to screen.
    e.Graphics.FillPie(redBrush, rect, startAngle, sweepAngle)
End Sub

Remarks

This method fills the interior of a pie section defined by an arc of an ellipse and the two radial lines that intersect with the endpoints of the arc. The ellipse is defined by the bounding rectangle. The pie section consists of the two radial lines defined by the startAngle and sweepAngle parameters and the arc between the intersections of those radial lines with the ellipse.

If the sweepAngle parameter is greater than 360 degrees or less than -360 degrees, it is treated as if it were 360 degrees or -360 degrees, respectively.
