Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData instance to draw on.

brush  Brush

The Brush to use for filling the polygon.

points  IEnumerablePoint

The vertices of the polygon to draw.

drawingOptions  DrawingOptions  (Optional)

A DrawingOptions instance that specifies the drawing options to use. If , then the default options are used. This parameter is optional.
Default value: .

asyncConfig  AsyncConfig  (Optional)

The configuration of the asynchronous operation such as parallelization, cancellation, reporting progress, etc. When Progress is set in this parameter, then this library always passes a DrawingOperation instance to the generic methods of the IAsyncProgress interface. This parameter is optional.
Default value: .

Return Value

Usage Note

Every pair of two consecutive points specifies a side of the polygon. In addition, if the last point and the first point do not coincide, they specify the last side of the polygon.

This method does not use optimized shortcuts. If the same polygon is filled repeatedly, creating a Path with PreferCaching enabled and adding the polygon to it can provide a better performance.

In .NET Framework 4.0 and above you can use also the FillPolygonAsync methods.

To finish the operation and to get the exception that occurred during the operation you have to call the EndFillPolygon method.

This method is not a blocking call even if the MaxDegreeOfParallelism property of the asyncConfig parameter is 1.
