ISurfaceImageSourceNative interface
Provides the implementation of a shared fixed-size surface for DirectX drawing.
Note If the surface is larger than the screen size, use IVirtualSurfaceImageSourceNative instead.
Members
The ISurfaceImageSourceNative interface inherits from the IUnknown interface. ISurfaceImageSourceNative also has these types of members:
Methods
The ISurfaceImageSourceNative interface has these methods.
| Method | Description |
|---|---|
| BeginDraw |
Opens the supplied DXGI surface for drawing. |
| EndDraw |
Closes the surface draw operation. |
| SetDevice |
Sets the DXGI device, created with D3D11_CREATE_DEVICE_BGRA_SUPPORT, that will draw the surface. |
Remarks
This interface provides the native implementation of the Windows::UI::Xaml::Media::Imaging::SurfaceImageSource Windows runtime type. To obtain a pointer to ISurfaceImageSourceNative, you must cast a SurfaceImageSource instance to IInspectable or IUnknown, and call QueryInterface.
Microsoft::WRL::ComPtr<ISurfaceImageSourceNative> m_sisNative; // ... IInspectable* sisInspectable = (IInspectable*) reinterpret_cast<IInspectable*>(surfaceImageSource); sisInspectable->QueryInterface(__uuidof(ISurfaceImageSourceNative), (void **)&m_sisNative)
