示例1: LayoutRoot_Loaded
async void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
{
// get visuals from xaml object
_touchAreaVisual = GetVisual(this.TouchArea);
var imagePanelVisual = GetVisual(this.ImagePanel);
// get compositor
_compositor = imagePanelVisual.Compositor;
// load the background image
var image = _compositor.DefaultGraphicsDevice.CreateImageFromUri(new Uri("ms-appx:///Assets/White.png"));
await image.CompleteLoadAsync();
// todo: not sure why GaussianBlurEffect doesn't work??
// Got a feeling it might have something to do with the Source setting,
// maybe it's just not supported yet?
var effectDefination = new SaturationEffect // new GaussianBlurEffect
{
//BorderMode = EffectBorderMode.Soft,
//BlurAmount = 5f,
//Optimization = EffectOptimization.Quality,
Source = new CompositionEffectSourceParameter("Overlay")
};
// create the actual effect
var effectFactory = _compositor.CreateEffectFactory(effectDefination);
var effect = effectFactory.CreateEffect();
effect.SetSourceParameter("Overlay", image);
// create the effect visual
_effectVisual = _compositor.CreateEffectVisual();

_effectVisual.Size = new Vector2((float)this.ImagePanel.ActualWidth, (float)this.ImagePanel.ActualHeight);
// place the effect visual onto the UI
