Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData instance to draw on.

color  Color32

The color of the rounded rectangle to fill.

bounds  Rectangle

The bounding rectangle that defines the rounded rectangle.

radiusTopLeft  Int32

The size of the top-left corner radius of the rounded rectangle.

radiusTopRight  Int32

The size of the top-right corner radius of the rounded rectangle.

radiusBottomRight  Int32

The size of the bottom-right corner radius of the rounded rectangle.

radiusBottomLeft  Int32

The size of the bottom-left corner radius of the rounded rectangle.

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 a rounded rectangle, the right/bottom values of the bounding rectangle are exclusive, so if the width or height is zero, then nothing is drawn.

If a corner radius parameter is negative, its absolute value will be used. If the sum of any adjacent corner radius parameters is greater than the corresponding side of the bounding rectangle, then all corner radius parameters will be scaled down proportionally to fit into the bounding rectangle.

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