Graphics::FillClosedCurve Method (Brush, array<PointF>, FillMode)
Fills the interior of a closed cardinal spline curve defined by an array of PointF structures using the specified fill mode.
Assembly: System.Drawing (in System.Drawing.dll)
public: void FillClosedCurve( Brush^ brush, array<PointF>^ points, FillMode fillmode )
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 define the spline.
- fillmode
- Type: System.Drawing.Drawing2D::FillMode
Member of the FillMode enumeration that determines how the curve is filled.
| Exception | Condition |
|---|---|
| ArgumentNullException | brush is nullptr. -or- points is nullptr. |
This method fills the interior of a closed cardinal spline that passes through each point in the array. If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.
The array of points must contain at least four Point structures.
This method uses a default tension of 0.5.
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 red brush.
Creates an array of four points to define a spline.
Sets the fill mode to Winding.
Fills the curve on the screen.
The curve has a default tension of 0.5.
public: void FillClosedCurvePointFFillMode( PaintEventArgs^ e ) { // Create solid brush. SolidBrush^ redBrush = gcnew SolidBrush( Color::Red ); // Create array of points for curve. PointF point1 = PointF(100.0F,100.0F); PointF point2 = PointF(200.0F,50.0F); PointF point3 = PointF(250.0F,200.0F); PointF point4 = PointF(50.0F,150.0F); array<PointF>^ points = {point1,point2,point3,point4}; // Set fill mode. FillMode newFillMode = FillMode::Winding; // Fill curve on screen. e->Graphics->FillClosedCurve( redBrush, points, newFillMode ); }
