The following example calls the application-defined SafeRelease macro to free the visual object. It is good programming practice to free any visual objects as soon as you no longer need them. Step 10: Free the DirectComposition objects Commit the visual to be composed and displayed. The resulting composition appears in the target window. Set the visual to be the root of the visual tree.Ĭall the IDCompositionDevice::Commit method to commit the batch of commands to DirectComposition for processing. Set the root visual of the visual tree by calling the IDCompositionTarget::SetRoot method. Step 8: Set the root visual of the visual tree to the upper-left corner of the composition target window. Set the horizontal and vertical position of the visual relative Because it is the root visual, the container for this visual is the composition target window. This next example sets the bitmap content for the visual, and the horizontal and vertical position of the visual relative to upper-left corner of its container. Step 7: Bind surface to visual and set the properties of the visual objectĬall the methods of the visual object's IDCompositionVisual interface to set the properties of the visual. Call an application-defined macro to free the surface pointer. HBitmapOld = (HBITMAP)SelectObject(hBitmapDC, hBitmap) īitBlt(hSurfaceDC, pointOffset.x, pointOffset.y,īitmapWidth, bitmapHeight, hBitmapDC, 0, 0, SRCCOPY) HBitmapDC = CreateCompatibleDC(hSurfaceDC) Create a compatible DC and select the surface Hr = pDXGISurface->GetDC(FALSE, &hSurfaceDC) Get the device context (DC) for the surface. Reinterpret_cast(&pDXGISurface), &pointOffset) Hr = pDCSurface->BeginDraw(NULL, _uuidof(IDXGISurface1), Hr = m_pDCompDevice->CreateSurface(bitmapWidth, bitmapHeight,ĭXGI_FORMAT_B8G8R8A8_UNORM, DXGI_ALPHA_MODE_IGNORE, &pDCSurface)

rendering on the surface using GDI via GetDC. The DXGI_FORMAT_B8G8R8A8_UNORM flag is required for Create a DirectComposition-compatible surface that is the same size IDCompositionSurface *pDCSurface = nullptr īmpSize = GetObject(hBitmap, sizeof(BITMAP), &bmp) HRESULT DemoApp::M圜reateGDIRenderedDCompSurface(HBITMAP hBitmap, ppSurface - the composition surface object. M圜reateGDIRenderedDCompSurface - Creates a DirectComposition surface and The following function creates a Microsoft DirectComposition surface and draws the bitmap on the surface. Hr = M圜reateGDIRenderedDCompSurface(m_hBitmap, &pSurface) Create a composition surface and render a GDI bitmap IDCompositionSurface *pSurface = nullptr Step 6: Create a composition surface and render a bitmap to the surfaceĬreate an IDCompositionSurface pointer. Hr = m_pDCompDevice->CreateVisual(&pVisual) For more information, see Properties of a visual object. The method retrieves an IDCompositionVisual pointer used to set the properties of the visual. Use the IDCompositionDevice::CreateVisual method to create a visual object. Hr = m_pDCompDevice->CreateTargetForHwnd(m_hwnd, TRUE, &m_pDCompTarget) Create the composition target object based on the Calling CreateTargetForHwnd binds the device object to the application window that will display the composition. Use the IDCompositionDevice::CreateTargetForHwnd method to create an instance of the composition target object. Step 4: Create the composition target object Hr = DCompositionCreateDevice(pDXGIDevice, Create the DirectComposition device object.

The function retrieves an IDCompositionDevice pointer used to create all other DirectComposition objects used in a composition. Use the DCompositionCreateDevice function to create an instance of the DirectComposition device object, specifying the IDXGIDevice pointer retrieved in the previous step. Step 3: Create the DirectComposition device object Hr = m_pD3D11Device->QueryInterface(&pDXGIDevice) Create the DXGI device used to create bitmap surfaces. Check the result of calling D3D11CreateDriver. DirectComposition will use the Microsoft DirectX Graphics Infrastructure (DXGI) object to create all surface objects for the DirectComposition device. Use the QueryInterface method to retrieve the IDXGIDevice pointer from the Direct3D device object. Step 2: Retrieve a pointer to the DXGI object flag enables rendering on surfaces using Direct2D. Use the D3D11CreateDevice function from the Microsoft Direct3D API to create an instance of a device object that represents the display adapter. Instructions Step 1: Create the Direct3D device object

This topic demonstrates how to create and initialize the minimum set of Microsoft DirectComposition objects needed to create a simple composition. For more info, see Modernize your desktop app using the Visual layer. For apps on Windows 10, we recommend using Windows.UI.Composition APIs instead of DirectComposition.
