Example
The following example creates three GradientGlowFilter objects and compares them;
filter_1 is created by using the GradientGlowFilter construtor; 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.GradientGlowFilter;
var colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF];
var alphas:Array = [0, 1, 1, 1];
var ratios:Array = [0, 63, 126, 255];
var filter_1:GradientGlowFilter = new GradientGlowFilter(0, 45, colors,
alphas, ratios, 55, 55, 2.5, 2, "outer", false);
var filter_2:GradientGlowFilter = filter_1;
var clonedFilter:GradientGlowFilter = 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]
// >> type: outer
// >> knockout: false
// >> strength: 2.5
// >> quality: 2
// >> blurY: 55
