Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData instance to draw on.

brush  Brush

The Brush to use for filling the Path.

path  Path

The Path instance to fill.

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

If the Transformation property of drawingOptions is not the identity matrix, then the path region is not cached, even if PreferCaching is enabled. To improve the performance of filling transformed paths repeatedly, apply the transformations to the path instance instead, and use the identity matrix in drawingOptions.

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

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

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