Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData instance to draw on.

color  Color32

The color of the ellipse to fill.

bounds  Rectangle

The bounding rectangle that defines the ellipse.

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

When filling an ellipse, the right/bottom values of the bounding rectangle are exclusive, so if the width or height is zero, then nothing is drawn.

This method does not use optimized shortcuts. If the same ellipse is filled repeatedly, creating a Path with PreferCaching enabled and adding the ellipse 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.
