Flash Player 9, AIR 1.1

The MaskEffect class is an abstract base class for all effects that animate a mask, such as the wipe effects and the Iris effect. This class encapsulates methods and properties that are common among all mask-based effects.

A mask effect uses an overlay, called a mask, to perform the effect. By default, the mask is a rectangle with the same size as the target component.

The before or after state of the target component of a mask effect must be invisible. That means a mask effect always makes a target component appear on the screen, or disappear from the screen.

You use the scaleXFrom, scaleYFrom, scaleXTo, and scaleX properties to specify the initial and final scale of the mask, where a value of 1.0 corresponds to scaling the mask to the size of the target component, 2.0 scales the mask to twice the size of the component, 0.5 scales the mask to half the size of the component, and so on. To use any one of these properties, you must specify all four.

You use the xFrom, yFrom, xTo, and yTo properties to specify the coordinates of the initial position and final position of the mask relative to the target component, where (0, 0) corresponds to the upper left corner of the target. To use any one of these properties, you must specify all four.

The coordinates of the initial and final position of the mask depend on the type of effect and whether the show property is true or false. For example, for the WipeLeft effect with a show value of false, the coordinates of the initial mask position are (0, 0),corresponding to the upper-left corner of the target, and the coordinates of the final position are the upper-right corner of the target (width, 0), where width is the width of the target.

For a show value of true for the WipeLeft effect, the coordinates of the initial mask position are (width, 0), and the coordinates of the final position are (0, 0).

Function called when the effect creates the mask. The default value is a function that returns a Rectangle with the same dimensions as the target.

The custom mask function has the following signature:

      public function createLargeMask(targ:Object, bounds:Rectangle):Shape
      {
          var myMask:Shape = new FlexShape();
     
          // Create mask.
     
          return myMask;
      }

Your custom mask function takes an argument corresponding to the target component of the effect, and a second argument that defines the dimensions of the target so that you can correctly size the mask. You use that argument to access properties of the target component, such as width and height, so that you can create a mask with the correct size.

The function returns a single Shape object that defines the mask.

Specifies that the target component is becoming visible, true, or invisible, false. If you specify this effect for a showEffect or hideEffect trigger, Flex sets the showTarget property for you, either to true if the component becomes visible, or false if the component becomes invisible. If you use this effect with a different effect trigger, you should set it yourself, often within the event listener for the startEffect event.

Returns the component properties modified by this effect. This method returns an Array containing: [ "visible", "width", "height" ]. Since the WipeDown, WipeLeft, WipeRight, and WipeDown effect subclasses all modify these same properties, those classes do not implement this method.

If you subclass the MaskEffect class to create a custom effect, and it modifies a different set of properties on the target, you must override this method and return an Array containing a list of the properties modified by your subclass.

Array — An Array of Strings specifying the names of the properties modified by this effect.

Dispatched when the effect ends.

When an effect plays a single time, this event occurs at the same time as an effectEnd event. If you configure the effect to repeat, it occurs at the end of every repetition of the effect, and the endEffect event occurs after the effect plays for the final time.

The TweenEvent.TWEEN_END constant defines the value of the event object's type property for a tweenEnd event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`value`	The value passed to the `onTweenEnd()` method.

Dil Sürümü:

Dispatched when the effect starts, which corresponds to the first call to the onMoveTweenUpdate() and onScaleTweenUpdate() methods. Flex also dispatches the first tweenUpdate event for the effect at the same time.

The Effect.effectStart event is dispatched before the tweenStart event.

The TweenEvent.TWEEN_START constant defines the value of the event object's type property for a tweenStart event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

Dispatched every time the effect updates the target. The dispatching of this event corresponds to the calls to the onMoveTweenUpdate() and onScaleTweenUpdate() methods.

The TweenEvent.TWEEN_UPDATE constant defines the value of the event object's type property for a tweenUpdate event.

The properties of the event object have the following values:
