ReadableBitmapDataExtensionsBeginToWriteableBitmap(IReadableBitmapData, AsyncConfig) Method

public static IAsyncResult BeginToWriteableBitmap(
	this IReadableBitmapData source,
	AsyncConfig? asyncConfig = null
)

<ExtensionAttribute>
Public Shared Function BeginToWriteableBitmap ( 
	source As IReadableBitmapData,
	Optional asyncConfig As AsyncConfig = Nothing
) As IAsyncResult

public:
[ExtensionAttribute]
static IAsyncResult^ BeginToWriteableBitmap(
	IReadableBitmapData^ source, 
	AsyncConfig^ asyncConfig = nullptr
)

[<ExtensionAttribute>]
static member BeginToWriteableBitmap : 
        source : IReadableBitmapData * 
        ?asyncConfig : AsyncConfig 
(* Defaults:
        let _asyncConfig = defaultArg asyncConfig null
*)
-> IAsyncResult 

Parameters

source  IReadableBitmapData

The source IReadableBitmapData instance to convert.

asyncConfig  AsyncConfig  (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

In .NET Framework 4.0 and above you can use also the ToWriteableBitmapAsync method.

To get the result or the exception that occurred during the operation you have to call the EndToWriteableBitmap method.

This method is not a blocking call even if the MaxDegreeOfParallelism property of the asyncConfig parameter is 1.
