Fills an ellipse with the specified color.

Definition

Namespace: KGySoft.Drawing.Shapes
Assembly: KGySoft.Drawing.Core (in KGySoft.Drawing.Core.dll) Version: 9.1.1

C#

public static void FillEllipse(
	this IReadWriteBitmapData bitmapData,
	Color32 color,
	Rectangle bounds,
	DrawingOptions? drawingOptions = null
)

VB

<ExtensionAttribute>
Public Shared Sub FillEllipse ( 
	bitmapData As IReadWriteBitmapData,
	color As Color32,
	bounds As Rectangle,
	Optional drawingOptions As DrawingOptions = Nothing
)

C++

public:
[ExtensionAttribute]
static void FillEllipse(
	IReadWriteBitmapData^ bitmapData, 
	Color32 color, 
	Rectangle bounds, 
	DrawingOptions^ drawingOptions = nullptr
)

F#

[<ExtensionAttribute>]
static member FillEllipse : 
        bitmapData : IReadWriteBitmapData * 
        color : Color32 * 
        bounds : Rectangle * 
        ?drawingOptions : DrawingOptions 
(* Defaults:
        let _drawingOptions = defaultArg drawingOptions null
*)
-> unit

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: .

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 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.

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 BeginFillEllipse or FillEllipseAsync (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.
