Example
The following example uses
Function.call() to make a function behave as a method of
another object, without storing the function in the object:
function myObject() {
}
function myMethod(obj) {
trace("this == obj? " + (this == obj));
}
var obj:Object = new myObject();
myMethod.call(obj, obj);
The trace() statement displays:
this == obj? true

public class GlowFilter
extends BitmapFilter
The GlowFilter class lets you apply a glow effect to various objects in Flash. You have several
options for the style of the glow, including inner or outer glow and knockout mode. The glow
filter is similar to the drop shadow filter with the
distance and angle properties of the drop
shadow set to 0.
The use of filters depends on the object to which you apply the filter:
■ To apply filters to movie clips, text fields, and buttons at runtime, use the filters
property. Setting the
filters property of an object does not modify the object and can be
undone by clearing the
filters property.
■ To a pp ly f ilt ers to Bit map Data instances, use the BitmapData.applyFilter() method.
Calling
applyFilter() on a BitmapData object takes the source BitmapData object and
the filter object and generates a filtered image as a result.
