Graphics.FillPolygon Method (Brush, Point(), FillMode)


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

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

Public Sub FillPolygon (
	brush As Brush,
	points As Point(),
	fillMode As FillMode


Type: System.Drawing.Brush

Brush that determines the characteristics of the fill.

Type: System.Drawing.Point()

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

Type: System.Drawing.Drawing2D.FillMode

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

  • Sets the fill mode to Winding.

  • Fills the polygonal area on the screen.

Public Sub FillPolygonPointFillMode(ByVal e As PaintEventArgs)

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

    ' Create points that define polygon.
    Dim point1 As New Point(50, 50)
    Dim point2 As New Point(100, 25)
    Dim point3 As New Point(200, 5)
    Dim point4 As New Point(250, 50)
    Dim point5 As New Point(300, 100)
    Dim point6 As New Point(350, 200)
    Dim point7 As New Point(250, 250)
    Dim curvePoints As Point() = {point1, point2, point3, point4, _
    point5, point6, point7}

    ' Define fill mode.
    Dim newFillMode As FillMode = FillMode.Winding

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