F#

[<ExtensionAttribute>]
static member FillPie : 
        bitmapData : IReadWriteBitmapData * 
        color : Color32 * 
        bounds : Rectangle * 
        startAngle : float32 *

        parallelConfig : ParallelConfig -> bool

Parameters

bitmapData IReadWriteBitmapData: The IReadWriteBitmapData instance to draw on.
color Color32: The color of the pie to fill.
bounds Rectangle: 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: A DrawingOptions instance that specifies the drawing options to use. If , then the default options are used.
parallelConfig ParallelConfig: The configuration of the 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. If , then the degree of parallelization is configured automatically.

Return Value

Boolean
, if the operation completed successfully.
, if the operation has been canceled and the ThrowIfCanceled property of the parallelConfig parameter was .

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

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.

Note

This method blocks the caller as it executes synchronously, though the parallelConfig parameter allows configuring the degree of parallelism, cancellation and progress reporting. Use the BeginFillPie or FillPieAsync (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.
OperationCanceledException	The operation has been canceled and the ThrowIfCanceled property in parallelConfig was .
