How to: Create Multiple Visual Effects
Multiple visual effects can be applied to a single visible object using the BitmapEffectGroup. The following example shows how to apply a BlurBitmapEffect and a DropShadowBitmapEffect to create a blurry button with a shadow behind it.
Example
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Media.Effects;
namespace SDKSample
{
public partial class MultipleEffectExample : Page
{
public MultipleEffectExample()
{
Button myButton = new Button();
myButton.Content = "DropShadow under this Button";
myButton.Margin = new Thickness(50);
myButton.Width = 300;
// Create the BitmapEffects to apply to the button.
BlurBitmapEffect myBlurBitmapEffect = new BlurBitmapEffect();
myBlurBitmapEffect.Radius = 2;
DropShadowBitmapEffect myDropShadowBitmapEffect = new DropShadowBitmapEffect();
myDropShadowBitmapEffect.Color = Colors.Black;
myDropShadowBitmapEffect.Direction = 320;
myDropShadowBitmapEffect.ShadowDepth = 30;
myDropShadowBitmapEffect.Softness = 1;
myDropShadowBitmapEffect.Opacity = 0.5;
BitmapEffectGroup myBitmapEffectGroup = new BitmapEffectGroup();
myBitmapEffectGroup.Children.Add(myBlurBitmapEffect);
myBitmapEffectGroup.Children.Add(myDropShadowBitmapEffect);
myButton.BitmapEffect = myBitmapEffectGroup;
StackPanel myStackPanel = new StackPanel();
myStackPanel.Children.Add(myButton);
this.Content = myStackPanel;
}
}
}
