如何确定AS3中的形状填充颜色?

Question

我在舞台上的MovieClip内有一个圆圈，实例名称为holder。我想得到那个圆圈的颜色。

我成功地定位了那个圆圈，如代码所示。我可以使用变换更改其颜色，但我找不到实际检查其颜色的方法。

holder.getChildAt(0);

好的，正如我在回复中所说，最后，这是我需要的。它可以稍微简化和优化，但是，就我的需求而言，它足够快了！:)

function decimalToHex(decimal: int, padding: int = 2): String {
var hex: String = Number(decimal).toString(16);
while (hex.length < padding) {
hex = "0" + hex;
}
return hex.toUpperCase();
}
function getColor(what: Object):void {
var obj = what.getChildAt(0);
var bmd: BitmapData = new BitmapData(obj.width, obj.height, true, 0x00ffffff);
//In the 0x00ffffff color, leading two zeros are alpha channel
bmd.draw(obj);
var img = new Bitmap(bmd);
var stp = "";
for (var l: uint = 0; l < img.height && stp == ""; l++) {
for (var m: uint = 0; m < img.width && stp == ""; m++) {
var color = decimalToHex(bmd.getPixel32(m, l), 8);
if (int(parseInt(color.substr(0, 2), 16)) > 0) {
color = "#" + color.substr(2);
stp = "stop";
// Display color in a text box named as "what"'s name + letter "c"
param.getChildByName(what.name + "c").text = color;
}
}
}
}
getColor(holder); //As in question, my shape is inside it's holder
