BitmapEncoder.CreateAsync Method

  • Reference

Definition

Namespace:
Windows.Graphics.Imaging

Overloads

CreateAsync(Guid, IRandomAccessStream)

Asynchronously creates a new BitmapEncoder.
CreateAsync(Guid, IRandomAccessStream, IIterable<KeyValuePair<String,BitmapTypedValue>>)

Asynchronously creates a new BitmapEncoder for the specified codec with the specified encoding options and initializes it on a stream.

CreateAsync(Guid, IRandomAccessStream)

Edit

Asynchronously creates a new BitmapEncoder.

public:
 static IAsyncOperation<BitmapEncoder ^> ^ CreateAsync(Platform::Guid encoderId, IRandomAccessStream ^ stream);
/// [Windows.Foundation.Metadata.Overload("CreateAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<BitmapEncoder> CreateAsync(winrt::guid const& encoderId, IRandomAccessStream const& stream);
[Windows.Foundation.Metadata.Overload("CreateAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<BitmapEncoder> CreateAsync(Guid encoderId, IRandomAccessStream stream);
function createAsync(encoderId, stream)
Public Shared Function CreateAsync (encoderId As Guid, stream As IRandomAccessStream) As IAsyncOperation(Of BitmapEncoder)

Parameters

encoderId
Guid

Platform::Guid

winrt::guid

The unique identifier of the specified encoder.

stream
IRandomAccessStream

The output stream.

Returns

IAsyncOperation<BitmapEncoder>

An object that manages the asynchronous creation of a new BitmapEncoder.

Attributes
OverloadAttribute RemoteAsyncAttribute

Remarks

An application must always specify the encoderId in order to create a BitmapEncoder. The unique identifiers of the built-in encoders are available as properties on BitmapEncoder. In addition, the unique identifier of any installed encoder can be obtained by using the GetEncoderInformationEnumerator method.

BitmapEncoder expects that the output stream is empty. You can ensure that the stream is empty by setting its Size property to 0.
