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.
Assembly: System.Drawing (in System.Drawing.dll)
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.
- fillMode
- Type: System.Drawing.Drawing2D::FillMode
Member of the FillMode enumeration that determines the style of the fill.
| Exception | Condition |
|---|---|
| ArgumentNullException | brush is nullptr. -or- points is nullptr. |
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 = 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 ); }
