MatrixAnimationBase Class

Abstract class that, when implemented, animates a Matrix value.

Namespace: System.Windows.Media.Animation
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public abstract class MatrixAnimationBase : AnimationTimeline
public abstract class MatrixAnimationBase extends AnimationTimeline
public abstract class MatrixAnimationBase extends AnimationTimeline
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Notes to Inheritors: See the Custom Animations Overview for information about extending animation classes.

The following code example demonstrates how to use the derived MatrixAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).

  <StackPanel Margin="20">
    <Canvas HorizontalAlignment="Left" Width="340" Height="240" >

      <!-- The Button that is animated. -->
      <Button Margin="-30,0,0,0" MinWidth="100">
        Click
        <Button.RenderTransform>
          <MatrixTransform x:Name="myMatrixTransform">
            <MatrixTransform.Matrix >
              <Matrix OffsetX="10" OffsetY="100"/>
            </MatrixTransform.Matrix>
          </MatrixTransform>
        </Button.RenderTransform>
        <Button.Triggers>
          <EventTrigger RoutedEvent="Button.Loaded">
            <BeginStoryboard>
              <Storyboard>

                <!-- Animates the button's MatrixTransform using MatrixAnimationUsingKeyFrames. 
                Animates to first Matrix in the first 0.2 seconds, to second Matrix in the next
                second, and then starts over. Notice that the first KeyFrame stretches the button
                and skews it using the M11 and M12 Matrix properties respectively. Also, animations are 
                using Discrete interpolation, so the MatrixTransform appears to "jump" from one value 
                to the next. -->
