Parameters

bitmapData IReadWriteBitmapData: The IReadWriteBitmapData instance to draw on.
color Color32: The color of the rounded rectangle to fill.
x Int32: The x-coordinate of the upper-left corner of the bounding rectangle that defines the rounded rectangle.
y Int32: The y-coordinate of the upper-left corner of the bounding rectangle that defines the rounded rectangle.
width Int32: The width of the bounding rectangle that defines the rounded rectangle.
height Int32: The height of the bounding rectangle that defines the rounded rectangle.
cornerRadius Int32: The size of the corner radius of the rounded rectangle for all corners.
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: .

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadWriteBitmapData. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

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

If cornerRadius is negative, the absolute value will be used. If it is greater than the half of the smaller side of the bounding rectangle, it will be adjusted to the half of the smaller side, so the result will be an oval shape. If the cornerRadius is 0, a simple filled rectangle will be drawn.

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.

Note

This method adjusts the degree of parallelization automatically, blocks the caller, and does not support cancellation or reporting progress. You can use the overloads that have a ParallelConfig parameter to configure these, while still executing the method synchronously. Alternatively, use the BeginFillRoundedRectangle or FillRoundedRectangleAsync (in .NET Framework 4.0 and above) methods to perform the operation asynchronously.

Exceptions

ArgumentNullException	bitmapData is .
OverflowException	The coordinates (after a possible transformation specified in drawingOptions) are outside the bounds of an int value.
