D3DImage.PixelHeight Property

Gets the height of the D3DImage, in pixels.

Namespace:  System.Windows.Interop
Assembly:  PresentationCore (in PresentationCore.dll)

public int PixelHeight { get; }

Property Value

Type: System.Int32
The height of the D3DImage, in pixels.

The value of PixelHeight 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 PixelHeight 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();
