Graphics::FillPolygon Method (Brush, array<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:
void FillPolygon(
	Brush^ brush, 
	array<PointF>^ points
)

Parameters

brush
Type: System.Drawing::Brush
Brush that determines the characteristics of the fill.
points
Type: array<System.Drawing::PointF>
Array of PointF structures that represent the vertices of the polygon to fill.

ExceptionCondition
ArgumentNullException

brush is nullptr.

-or-

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 actions:

  • Creates a solid blue brush.

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

  • Fills the polygonal area on the screen.


public:
   void FillPolygonPointF( 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};

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