1.3.6.3 Behaviors
Animation effects vary one or more properties of a shape. Variation of a property over time is called a behavior. Available behaviors are dependent on the type of shape being animated. For example, a geometric shape supports behaviors that change its color and size while a video shape supports behaviors that define its playback.
Behaviors belong to the basic types described in the following table:
|
Behavior type |
Description |
|---|---|
|
Animate |
Animates any property of an object that is either a numerical or a string value. |
|
Animate Color |
Animates the color values of an object. |
|
Animate Effect |
Allows image transformations and filter animations on an object. |
|
Animate Motion |
Animates position properties of an object by using either key-frame data or detailed path descriptions that include Bezier curves or lines. |
|
Animate Rotation |
Animates the orientation of an object. |
|
Animate Scale |
Animates the width and height of an object over time. |
A time node can combine multiple animations to create complex effects. For example, the "flash bulb" animation, which scales a shape larger while simultaneously fading it, uses two animation behavior elements. An example is shown in the following figure:
