Graphics.FillPolygon Method (Brush, PointF())


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

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

Public Sub FillPolygon (
	brush As Brush,
	points As PointF()


Type: System.Drawing.Brush

Brush that determines the characteristics of the fill.

Type: System.Drawing.PointF()

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

Exception Condition

brush is null.


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 PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a solid blue brush.

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

  • Fills the polygonal area on the screen.

Public Sub FillPolygonPointF(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim blueBrush As New SolidBrush(Color.Blue)

    ' Create points that define polygon.
    Dim point1 As New PointF(50.0F, 50.0F)
    Dim point2 As New PointF(100.0F, 25.0F)
    Dim point3 As New PointF(200.0F, 5.0F)
    Dim point4 As New PointF(250.0F, 50.0F)
    Dim point5 As New PointF(300.0F, 100.0F)
    Dim point6 As New PointF(350.0F, 200.0F)
    Dim point7 As New PointF(250.0F, 250.0F)
    Dim curvePoints As PointF() = {point1, point2, point3, point4, _
    point5, point6, point7}

    ' Fill polygon to screen.
    e.Graphics.FillPolygon(blueBrush, curvePoints)
End Sub
