RectAnimationBase Class
.NET Framework 3.0
Abstract class that, when implemented, animates a Rect value.

Notes to Inheritors:
See the Custom Animations Overview for information about extending animation classes.
The following code example demonstrates how to use the derived RectAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).

LinearRectKeyFrame creates a smooth, linear animation between values. --> <LinearRectKeyFrame Value="600,50,200,50" KeyTime="0:0:2" /> <!-- In the next half second, change height to 10. DiscreteRectKeyFrame creates a sudden "jump" between values. --> <DiscreteRectKeyFrame Value="600,50,200,10" KeyTime="0:0:2.5" /> <!-- In the final 2 seconds of the animation, go back to the starting position, width, and height. Spline key frames like SplineRectKeyFrame creates a variable transition between values depending on the KeySpline property. In this example, the animation starts off slow but toward the end of the time segment, it speeds up exponentially.--> <SplineRectKeyFrame Value="0,200,100,100" KeyTime="0:0:4.5" KeySpline="0.6,0.0 0.9,0.00" /> </RectAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </Path.Triggers> </Path> </StackPanel> </Page>
