Public NotInheritable Class PerceptionVideoFrameAllocator
Implements IDisposable

Herança: Object Platform::Object IInspectable PerceptionVideoFrameAllocator

Atributos: ActivatableAttribute ContractVersionAttribute MarshalingBehaviorAttribute ThreadingAttribute DeprecatedAttribute

Implementações: IClosable IDisposable

Requisitos do Windows

Família de dispositivos	Windows 10 (introduzida na 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduzida na v1.0)

Construtores

PerceptionVideoFrameAllocator(UInt32, BitmapPixelFormat, Size, BitmapAlphaMode)

Inicializa um novo PerceptionVideoFrameAllocator com as propriedades necessárias para uso pelo IPerceptionFrameProvider para criar PerceptionFrames publicados por meio de PerceptionFrameProviderManagerService::P ublishFrameForProvider.

Métodos

AllocateFrame()	Cria um PerceptionFrame vazio com as propriedades especificadas ao criar o PerceptionVideoFrameAllocator.
Close()	Libera recursos do sistema expostos por um objeto Windows Runtime.
CopyFromVideoFrame(VideoFrame)	Cria uma cópia profunda do vídeo FrameProvider com os bytes já preenchidos com o PerceptionFrame resultante.
Dispose()	Realiza tarefas definidas pelo aplicativo associadas à liberação ou à redefinição de recursos não gerenciados.
