Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData instance to draw on.

color  Color32

The color of the pie to fill.

bounds  RectangleF

The bounding rectangle that defines the ellipse from which the pie shape comes.

startAngle  Single

The starting angle of the pie shape, measured in degrees clockwise from the x-axis.

sweepAngle  Single

The sweep angle of the pie shape, measured in degrees clockwise from startAngle.

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  TaskConfig  (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

The pie shape is defined by an arc of an ellipse and the two radial lines that intersect with the endpoints of the arc.

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

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