Frame graph node for render capture. 更多...
| 頭： | #include <Qt3DRender/QRenderCapture> |
| qmake: | QT += 3drender |
| Since: | Qt 5.8 |
| 實例化： | RenderCapture |
| 繼承： | Qt3DRender::QFrameGraphNode |
該類在 Qt 5.8 引入。
| QRenderCapture (Qt3DCore::QNode * parent = nullptr) | |
| Qt3DRender::QRenderCaptureReply * | requestCapture () |
| Qt3DRender::QRenderCaptureReply * | requestCapture (const QRect & rect ) |
The QRenderCapture is used to capture rendering into an image at any render stage. Capturing must be initiated by the user and one image is returned per capture request. User can issue multiple render capture requests simultaniously, but only one request is served per QRenderCapture instance per frame.
構造函數創建實例，采用指定的 parent .
Used to request render capture. Only one render capture result is produced per requestCapture call even if the frame graph has multiple leaf nodes. The function returns a QRenderCaptureReply object, which receives the captured image when it is done. The user is responsible for deallocating the returned object by calling deleterLater().
注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .
