Public ReadOnly Property PixelWidth As Integer
The width of the D3DImage, in pixels.
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();
The value of PixelWidth can change when a new back buffer is assigned by a call to the SetBackBuffer method.
