Graphics::FillPolygon Method (Brush, array<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)

void FillPolygon(
	Brush^ brush, 
	array<PointF>^ points, 
	FillMode fillMode


Type: System.Drawing::Brush

Brush that determines the characteristics of the fill.

Type: array<System.Drawing::PointF>

Array of PointF 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.


brush is nullptr.


points is nullptr.

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.

   void FillPolygonPointFFillMode( PaintEventArgs^ e )
      // Create solid brush.
      SolidBrush^ blueBrush = gcnew SolidBrush( Color::Blue );

      // Create points that define polygon.
      PointF point1 = PointF(50.0F,50.0F);
      PointF point2 = PointF(100.0F,25.0F);
      PointF point3 = PointF(200.0F,5.0F);
      PointF point4 = PointF(250.0F,50.0F);
      PointF point5 = PointF(300.0F,100.0F);
      PointF point6 = PointF(350.0F,200.0F);
      PointF point7 = PointF(250.0F,250.0F);
      array<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 );
