Example
The following example creates three DropShadowFilter objects and compares them;
filter_1 is created by using the DropShadowFilter constructor; filter_2 is created by
setting it equal to filter_1; and clonedFilter is created by cloning filter_1. Notice that
although filter_2 evaluates as being equal to filter_1, clonedFilter, even though it
contains the same values as filter_1, does not.
import flash.filters.DropShadowFilter;
var filter_1:DropShadowFilter = new DropShadowFilter(15, 45, 0x000000, .8,
16, 16, 1, 3, false, false, false);
var filter_2:DropShadowFilter = filter_1;
var clonedFilter:DropShadowFilter = filter_1.clone();
trace(filter_1 == filter_2); // true
trace(filter_1 == clonedFilter); // false
for(var i in filter_1) {
trace(">> " + i + ": " + filter_1[i]);
// >> clone: [type Function]
// >> hideObject: false
// >> strength: 1
// >> blurY: 16
// >> blurX: 16
// >> knockout: false
// >> inner: false
// >> quality: 3
// >> alpha: 0.8
// >> color: 0
// >> angle: 45
// >> distance: 15
}
for(var i in clonedFilter) {
trace(">> " + i + ": " + clonedFilter[i]);
// >> clone: [type Function]
// >> hideObject: false
// >> strength: 1
// >> blurY: 16
// >> blurX: 16
// >> knockout: false
// >> inner: false
// >> quality: 3
// >> alpha: 0.8
// >> color: 0
// >> angle: 45
// >> distance: 15
