Constructors

PerceptionVideoFrameAllocator(UInt32, BitmapPixelFormat, Size, BitmapAlphaMode)

Initializes a new PerceptionVideoFrameAllocator with the required properties for use by the IPerceptionFrameProvider to create PerceptionFrames published via PerceptionFrameProviderManagerService::PublishFrameForProvider.

Methods

AllocateFrame()

Creates an empty PerceptionFrame with the properties specified when creating the PerceptionVideoFrameAllocator.

Close()

Releases system resources that are exposed by a Windows Runtime object.

CopyFromVideoFrame(VideoFrame)

Creates a deep copy of the video FrameProvider with the bytes already filled in with the resulting PerceptionFrame.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
