Remarks
An animation updates the value of a property over a period of time. An animation effect can be subtle, such as moving a Shape a few pixels left and right, or dramatic, such as enlarging an object to 200 times its original size while spinning it and changing its color. To create an animation in Windows Presentation Foundation (WPF), you associate an animation with an object's property value.
Target Values
The Int16Animation class creates a transition between two target values. To set its target values, use its From, To, and By properties. The following table summarizes how the From, To, and By properties may be used together or separately to determine an animation's target values.
| Properties specified | Resulting behavior |
|---|---|
| From | The animation progresses from the value specified by the From property to the base value of the property being animated or to a previous animation's output value, depending on how the previous animation is configured. |
| From and To | The animation progresses from the value specified by the From property to the value specified by the To property. |
| From and By | The animation progresses from the value specified by the From property to the value specified by the sum of the From and By properties. |
| To | The animation progresses from the animated property's base value or a previous animation's output value to the value specified by the To property. |
| By | The animation progresses from the base value of the property being animated or a previous animation's output value to the sum of that value and the value specified by the By property. |
Note
If you set both the To and By properties, the To property takes precedence and the By property is ignored.
To use other interpolation methods or animate between more than two target values, use a Int16AnimationUsingKeyFrames object.
For information about applying multiple animations to a single property, see Key-Frame Animations Overview.
Freezable Features
Because the Int16Animation class inherits from Freezable, Int16Animation objects gain several special features, which include the following: they can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.
