ScaleAnimation Client Reference
The ScaleAnimation scales the size of the target element by the given scaleFactor
(i.e. a scaleFactor of .5 will shrink it in half and a scaleFactor of 2.0
will double it). If scaleFont is true, the size of the font will also scale with the element. If
center is true, then the element's center will not move as it is scaled. It is important to note that
the target must be positioned (i.e. absolutely) so that setting its top/left properties will change
its location in order for center to have an effect.
ScaleAnimation Client Properties
| Name | Description |
|---|
| center | Whether the target should stay centered while scaling |
| duration | Length of the animation in seconds. The default is 1. |
| events | The collection of event handlers for this behavior. This property should only be used by derived behaviors and should not be publicly called by other code. |
| fontUnit | Unit of the font, which is only used if scaleFont is true.
The default value is 'pt'. |
| fps | Number of steps per second. The default is 25. |
| id | |
| isActive | true if animation is active, false if not. |
| isInitialized | |
| isPlaying | true if animation is playing, false if not. |
| isUpdating | |
| percentComplete | Percentage of the animation already played. |
| scaleFactor | The amount to scale the target (a scaleFactor of .5 will
shrink it in half and a scaleFactor of 2.0 will double it). The default value is
1, which does no scaling. |
| scaleFont | Whether the font should be scaled along with the size |
| target | |
| unit | Length unit for the size of the target. The default value is 'px'. |
ScaleAnimation Client Methods
| Name | Description |
|---|
| beginUpdate | |
| dispose |
Dispose the animation
|
| endUpdate | |
| getAnimatedValue |
Get the amount to scale the target |
| initialize | |
| interpolate |
The interpolate function is used to find the appropriate value between starting and
ending values given the current percentage.
|
| onEnd |
Wipe the cached values after the animation completes
|
| onStart |
Cache the initial size because it will be used to determine how much to scale the element at each step of the animation
|
| onStep |
The onStep method is called repeatedly to progress the animation through each frame
|
| pause |
Pause the animation if it is playing. Calling play will resume where
the animation left off.
|
| play |
Play the animation from the beginning or where it was left off when paused.
|
| play |
Create an animation, play it immediately, and dispose it when finished.
|
| raiseEnded |
Raise the ended event
|
| raisePropertyChanged | Raises a change notification event. |
| raiseStarted |
Raise the started event
|
| raiseStep |
Raise the step event
|
| setOwner |
Make this animation the child of another animation
|
| setValue |
Scale the target by the given percentage
|
| stop |
Stop playing the animation.
|
| updated | |
