strength (GradientGlowFilter.strength property)

The strength of the imprint or spread. The higher the value, the more color is imprinted and the stronger the contrast between the glow and the background. Valid values are 0 to 255. A value of 0 means that the filter is not applied. The default value is 1.

Example

The following example changes the strength property on an existing movie clip when a user clicks it.

import flash.filters.GradientGlowFilter;
var mc:MovieClip = createGradientGlowRectangle("GlowStrength");
mc.onRelease = function() {
    var filter:GradientGlowFilter = this.filters[0];
    filter.strength = 1;
    this.filters = new Array(filter);
}

function createGradientGlowRectangle(name:String):MovieClip {
    var art:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth());
    var w:Number = 100;
    var h:Number = 100;
    art.beginFill(0x003366);
    art.lineTo(w, 0);
    art.lineTo(w, h);
    art.lineTo(0, h);
    art.lineTo(0, 0);
    art._x = 20;
    art._y = 20;

    var colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF];
    var alphas:Array = [0, 1, 1, 1];
    var ratios:Array = [0, 63, 126, 255];
    var filter:GradientGlowFilter = new GradientGlowFilter(0, 45, colors, alphas, ratios, 55, 55, 2.5, 2, "outer", false);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    art.filters = filterArray;
    return art;
}
