D3DImage::PixelWidth Property
.NET Framework (current version)
Gets the width of the D3DImage, in pixels.
Assembly: PresentationCore (in PresentationCore.dll)
The value of PixelWidth can change when a new back buffer is assigned by a call to the SetBackBuffer method.
The following code example shows how to use the PixelWidth property to specify the changed region in the back buffer. For more information, see Walkthrough: Hosting Direct3D9 Content in WPF.
d3dimg.Lock(); // Repeatedly calling SetBackBuffer with the same IntPtr is // a no-op. There is no performance penalty. d3dimg.SetBackBuffer(D3DResourceType.IDirect3DSurface9, pSurface); HRESULT.Check(Render()); d3dimg.AddDirtyRect(new Int32Rect(0, 0, d3dimg.PixelWidth, d3dimg.PixelHeight)); d3dimg.Unlock();
