To further demonstrate the relationships between filter_1, filter_2, and clonedFilter,

the following example below modifies the

knockout property of filter_1. Modifying

knockout demonstrates that the clone() method creates a new instance based on the values

filter_1 instead of pointing to them in reference.

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.knockout); // false

trace(filter_2.knockout); // false

trace(clonedFilter.knockout); // false

filter_1.knockout = true;

trace(filter_1.knockout); // true

trace(filter_2.knockout); // true

trace(clonedFilter.knockout); // false

colors (GradientGlowFilter.colors property)

public colors : Array

An array of colors that defines a gradient. For example, red is 0xFF0000, blue is 0x0000FF,

and so on.

The

colors property cannot be changed by directly modifying its values. Instead, you must

get a reference to

colors, make the change to the reference, and then set colors to the

reference.

The

colors, alphas, and ratios properties are all related. The first element in the colors

array corresponds to the first element in the

alphas array and in the ratios array, and so on.
