strength (DropShadowFilter.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 shadow and the background. Valid values are from 0 to 255. The default is 1.

Example

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

import flash.filters.DropShadowFilter;
var mc:MovieClip = createDropShadowRectangle("DropShadowStrength");
mc.onRelease = function() {
    var filter:DropShadowFilter = this.filters[0];
    filter.strength = 0.6;
    this.filters = new Array(filter);
}

function createDropShadowRectangle(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 filter:DropShadowFilter = new DropShadowFilter(15, 45, 0x000000, 0.8, 16, 16, 1, 3, false, false, false);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    art.filters = filterArray;
    return art;
}
