Windows の要件

デバイス ファミリ
Windows 10 (10.0.10240.0 で導入)
API contract
Windows.Foundation.UniversalApiContract (v1.0 で導入)

コンストラクター

PerceptionVideoFrameAllocator(UInt32, BitmapPixelFormat, Size, BitmapAlphaMode)

IPerceptionFrameProvider で使用するために必要なプロパティを使用して新しい PerceptionVideoFrameAllocator を初期化し、PerceptionFrameProviderManagerService::P ublishFrameForProvider を介して発行された PerceptionFrame を作成します。

メソッド

AllocateFrame()

PerceptionVideoFrameAllocator の作成時に指定されたプロパティを使用して、空の PerceptionFrame を作成します。
Close()

Windows ランタイム オブジェクトによって公開されるシステム リソースを解放します。
CopyFromVideoFrame(VideoFrame)

ビデオ FrameProvider のディープ コピーを作成し、結果の PerceptionFrame が既に入力されているバイトを作成します。
Dispose()

アンマネージ リソースの解放またはリセットに関連付けられているアプリケーション定義のタスクを実行します。
