在纯AS工程中嵌入个别字体方法

整个工程如下：

package
{
import flash.display.Loader;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageQuality;
import flash.display.StageScaleMode;
import flash.events.Event;
import flash.events.ProgressEvent;
import flash.net.URLRequest;
import flash.system.LoaderContext;
import flash.text.Font;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.utils.getDefinitionByName;

public class FontTest extends Sprite
{
private var txt:TextField;
private var fontLoader:Loader;
public function FontTest():void
{
if(stage!=null){
init();
}else{
addEventListener(Event.ADDED_TO_STAGE,init);
}
}
private function init():void{
stage.quality = StageQuality.HIGH;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
stage.showDefaultContextMenu = false;

txt = new TextField();
txt.x = stage.stageWidth/3;
txt.y = stage.stageHeight/2;
txt.width = 500;
txt.height = 30;
addChild(txt);

fontLoader = new Loader();
fontLoader.load(new URLRequest("LoadFont.swf"), new LoaderContext(false, loaderInfo.applicationDomain));
fontLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
fontLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler);
}
private function progressHandler(e:ProgressEvent):void
{
var ratio:int = e.bytesLoaded / e.bytesTotal * 100;
txt.text = "loading... " + ratio + "%";
}

private function completeHandler(e:Event):void
{
fontLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, completeHandler);
fontLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
var MyFont:Class = getDefinitionByName("LoadFont_RoundHand") as Class;
// 注册全局字体
Font.registerFont(MyFont);
var myFont:Font = new MyFont() as Font;
// 应用字体
var format:TextFormat = new TextFormat(myFont.fontName, 25, null, true);
txt.defaultTextFormat = format;
// 嵌入字体
txt.embedFonts = true;
txt.text = "空山无人，水流花开。";
}
}
}
