Graphics.FillPie Method (Brush, Int32, Int32, Int32, Int32, Int32, Int32)

Fills the interior of a pie section defined by an ellipse specified by a pair of coordinates, a width, a height, and two radial lines.

	int x,
	int y,

Not applicable.

Parameters

brush

Brush that determines the characteristics of the fill.

x

The x-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse from which the pie section comes.

y

The y-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse from which the pie section comes.

width

Width of the bounding rectangle that defines the ellipse from which the pie section comes.

height

Height of the bounding rectangle that defines the ellipse from which the pie section comes.

startAngle

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

sweepAngle

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

Exception typeCondition

ArgumentNullException

brush is a null reference (Nothing in Visual Basic).

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.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a solid red brush.

  • Creates the location and size of 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 FillPieInt(PaintEventArgs e)
{
             
    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);
             
    // Create location and size of ellipse.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 100;
             
    // Create start and sweep angles.
    int startAngle =  0;
    int sweepAngle = 45;
             
    // Fill pie to screen.
    e.Graphics.FillPie(redBrush, x, y, width, height, startAngle, sweepAngle);
}

public void FillPieInt(PaintEventArgs e) 
{
    // Create solid brush.
    SolidBrush redBrush =  new SolidBrush(Color.get_Red());

    // Create location and size of ellipse.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 100;

    // Create start and sweep angles.
    int startAngle = 0;
    int sweepAngle = 45;

    // Fill pie to screen.
    e.get_Graphics().FillPie(redBrush, x, y, width, height, startAngle,
        sweepAngle);
} //FillPieInt
