Costruttori

PerceptionVideoFrameAllocator(UInt32, BitmapPixelFormat, Size, BitmapAlphaMode)

Inizializza un nuovo PerceptionVideoFrameAllocator con le proprietà necessarie per l'uso da parte di IPerceptionFrameProvider per creare PerceptionFrame pubblicati tramite PerceptionFrameProviderManagerService::P ublishFrameForProvider.

Metodi

AllocateFrame()	Crea un perceptionFrame vuoto con le proprietà specificate durante la creazione di PerceptionVideoFrameAllocator.
Close()	Rilascia le risorse di sistema esposte da un oggetto Windows Runtime.
CopyFromVideoFrame(VideoFrame)	Crea una copia completa del video FrameProvider con i byte già compilati con il PerceptionFrame risultante.
Dispose()	Esegue attività definite dall'applicazione, come rilasciare o reimpostare risorse non gestite.
