嵌入未知文件格式

Question

使用嵌入標籤，我們可以在SWF文件不僅SWF的或JPG文件等，同時也支持的文件格式，如嵌入：

Embed[(source="mzip.zip", mimeType="application/octet-stream")]

public static MyZip:Class;

當我實例這樣一類，是什麼我得到的物體類型？是否有可能從這個類中獲得一個ByteArray？

當我這樣做： package { import flash.utils.ByteArray;

public final class Resource {  
    [Embed(source="p2.zip", mimeType="application/octet-stream")] 
    public static const MyZip:Class; 

    public static function getByteArrayFromZip():ByteArray { 
     var zip:ByteArray = new MyZip as ByteArray; 
     return zip; 
    } 
} 

}

和

public class Main extends Sprite {
private var ship:Bitmap; private var lib:FZipLibrary;

public function Main() {    
     lib = new FZipLibrary();  
     lib.formatAsBitmapData(".jpg");  
     lib.addEventListener(Event.COMPLETE,onCompleteHandler); 

     var fzip:FZip = new FZip(); 
     fzip.loadBytes(Resource.getByteArrayFromZip()); 
     lib.addZip(fzip); 
    } 

    private function onCompleteHandler(evt:Event) { 
     var image:BitmapData = lib.getBitmapData("assets/graphics/scratchers/myimg.jpg"); 
     trace("Size: " + image.width + "x" + image.height); 
     var sa0img0:Bitmap = new Bitmap(image); 
     addChild(sa0img0); 
    } 
} 

}

的我得到以下錯誤： TypeError: Error #1009: Cannot access a property or method of a null object reference. at Main/onCompleteHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at deng.fzip::FZipLibrary/processNext() at deng.fzip::FZipLibrary/loaderCompleteHandler()

是的，只是實例MyZip和投爲ByteArray。

Embed[(source="mzip.zip", mimeType="application/octet-stream")] 
public static var MyZip:Class; 

var zip:ByteArray = new MyZip() as ByteArray;
