Graphics.FillPolygon Method (Brush, PointF[], FillMode)

Fills the interior of a polygon defined by an array of points specified by PointF structures using the specified fill mode.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void FillPolygon(
	Brush brush,
	PointF[] points,
	FillMode fillMode
)

Parameters

brush
Type: System.Drawing.Brush

Brush that determines the characteristics of the fill.

points
Type: System.Drawing.PointF[]

Array of PointF structures that represent the vertices of the polygon to fill.

fillMode
Type: System.Drawing.Drawing2D.FillMode

Member of the FillMode enumeration that determines the style of the fill.

ExceptionCondition
ArgumentNullException

brush is null.

-or-

points is null.

Every two consecutive points in the array specify a side of the polygon. In addition, if the last point and the first point do not coincide, they specify the closing side of the polygon.

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 action:

  • Creates a solid blue brush.

  • Creates an array of seven points to define a polygon.

  • Sets the fill mode to Winding.

  • Fills the polygonal area on the screen.

public void FillPolygonPointFFillMode(PaintEventArgs e)
{

    // Create solid brush.
    SolidBrush blueBrush = new SolidBrush(Color.Blue);

    // Create points that define polygon.
    PointF point1 = new PointF(50.0F, 50.0F);
    PointF point2 = new PointF(100.0F, 25.0F);
    PointF point3 = new PointF(200.0F, 5.0F);
    PointF point4 = new PointF(250.0F, 50.0F);
    PointF point5 = new PointF(300.0F, 100.0F);
    PointF point6 = new PointF(350.0F, 200.0F);
    PointF point7 = new PointF(250.0F, 250.0F);
    PointF[] curvePoints = {point1, point2, point3, point4, point5, point6, point7};

    // Define fill mode.
    FillMode newFillMode = FillMode.Winding;

    // Fill polygon to screen.
    e.Graphics.FillPolygon(blueBrush, curvePoints, newFillMode);
}
