在ActionScript3的嵌入的位图 [英] Embed bitmap in ActionScript3

问题描述

我如何可以嵌入一个位图在ActionScript 3中，并得到的BitmapData？

How can I embed a bitmap in Actionscript 3 and get the BitmapData?

public class MyGame extends Sprite {
    [EMBED(source="Assets/helicopter1.png")] private static var BMClass:Class;
    public function MyGame() {
        var BM:Bitmap = new BMClass();
        var BMData:BitmapData = new BitmapData(BM.width, BM.height);
        BMData.draw(BM)
    }
}

我已经竭尽所能。如果我尝试实例化嵌入类（新BMClass（）; ）我得到这个错误：

I've tried everything. If I ever try to instantiate the embedded class (new BMClass();) I get this error:

类型错误：错误＃1007：实例化尝试对非构造。

如果我用

[内嵌（来源=资产/ helicopter1.png）私有静态无功BMClass：的​​BitmapData;

或类似的BitmapData东西为空。

or something similar the BitmapData is null.

编辑：

所以我想通了，嵌入的数据为空，但我想不出为什么。我做了什么错在嵌入？

So I figured out that the embedded data is null, but I can't figure out why. What did I do wrong in the embedding?

推荐答案

看起来，你是嵌入正确，如果你没有得到一个错误代码转换。您应该能够直接从位图得到的位图数据：

Looks like you are embedding correctly if you don't get an error transcoding. You should be able to get the bitmapData directly from the bitmap:

[Embed(source="picture.jpg")]
private var Picture:Class;

// create a bitmap of the embedded
var pic:Bitmap = new Picture();

// add to display list
addChild(pic);

// if you need to get the bitmapData for something else
var bitmapData:BitmapData = pic.bitmapData;
