strength (GlowFilter.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. The default is 2.

Example

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

import flash.filters.GlowFilter;

var mc:MovieClip = createGlowFilterRectangle("GlowFilterStrength");
mc.onRelease = function() {
    var filter:GlowFilter = this.filters[0];
    filter.strength = 0.8;
    this.filters = new Array(filter);
}

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

    var filter:GlowFilter = new GlowFilter(0x000000, 0.8, 16, 16, 1, 3, false, false);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    rect.filters = filterArray;
    return rect;
}
