public alphas : Array
An array of alpha transparency values for the corresponding colors in the colors array. Valid values for each element in the array are 0 to 1. For example, 0.25 sets a transparency value of 25%.
The alphas property cannot be changed by directly modifying its values. Instead, you must get a reference to alphas, make the change to the reference, and then set alphas 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.
Availability: ActionScript 1.0; Flash Player 8
The following example demonstrates how to set the alphas property on an existing entity.
import flash.filters.GradientBevelFilter;
var mc:MovieClip = setUpFilter("alphasExample");
mc.onPress = function() {
var arr:Array = this.filters;
var alphas:Array = [0.2, 0, 0.2];
arr[0].alphas = alphas;
this.filters = arr;
}
mc.onRelease = function() {
var arr:Array = this.filters;
var alphas:Array = [1, 0, 1];
arr[0].alphas = alphas;
this.filters = arr;
}
function setUpFilter(name:String):MovieClip {
var art:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth());
var w:Number = 150;
var h:Number = 150;
art.beginFill(0xCCCCCC);
art.lineTo(w, 0);
art.lineTo(w, h);
art.lineTo(0, h);
art.lineTo(0, 0);
var colors:Array = [0xFFFFFF, 0xCCCCCC, 0x000000];
var alphas:Array = [1, 0, 1];
var ratios:Array = [0, 128, 255];
var filter:GradientBevelFilter = new GradientBevelFilter(5, 225, colors, alphas, ratios, 5, 5, 5, 2, "inner", false);
art.filters = new Array(filter);
return art;
}
