VAR快照：将ImageSnapshot = ImageSnapshot.captureImage（someSprite）;
var文件：的FileReference =新的FileReference（）;
file.save（snapshot.data，'abc.png'）;
 

在上面的code，我能够捕捉到的图像。

但我也想申请一个scalingMatrix（用于zoomIn输入/输出）和剪辑矩形吧。

怎么办呢？

我试过 capturebitmapdata 过，但我甚至不能得到正确的图像。请参见这里。所以我不希望使用它。

  SW = someSprite.stage.stageWidth;
SH = someSprite.stage.stageHeight;
VAR CR：矩形=新的Rectangle（X，Y，CW，CH）; //你要检查这个剪辑矩形不宜过冲你的舞台
// CR是剪裁矩形
VAR BMP：的BitmapData =新的BitmapData（SW，SH）;
bmp.draw（someSprite，NULL，NULL，NULL，CR）;

VAR BMP1：的BitmapData =新的BitmapData（CW，CH）;
bmp1.copyPixels（BMP，CR，新点（0,0））;
VAR ENC：JPEGEn codeR =新JPEGEn codeR（）;
VAR数据：的ByteArray = EN coder.en code（BMD 1）;
新的FileReference（）保存（数据，image.jpeg'）;
 

以上code，您可以只绘制剪辑矩形内的部分。 在我来说，我没有考虑到缩放矩阵，即使 我是用放大/缩小功能。

var snapshot:ImageSnapshot = ImageSnapshot.captureImage(someSprite);
var file:FileReference = new FileReference();
file.save(snapshot.data,'abc.png');

In the above code I am able to capture an image.

But I also want to apply a scalingMatrix(for zoomIn/Out) and a clipping rectangle to it.

How to do it?

I tried capturebitmapdata too, but with that I can't even get a proper image. See here. So I don't want to use that.

sw = someSprite.stage.stageWidth;            
sh = someSprite.stage.stageHeight;           
var cr:Rectangle = new Rectangle(x,y,cw,ch);//you have to check that this clip rectangle should not overshoot your stage
//cr is the clip rectangle
var bmp:BitmapData = new BitmapData(sw,sh);
bmp.draw(someSprite,null,null,null,cr);

var bmp1:BitmapData = new BitmapData(cw,ch);
bmp1.copyPixels(bmp,cr,new Point(0,0));
var enc:JPEGEncoder = new JPEGEncoder();
var data:ByteArray = encoder.encode(bmd1);
new FileReference().save(data,'image.jpeg');

The above code allows you to draw only the portion inside the clip rectangle. In my case I didn't have to take into account a scaling matrix, even though I was using zoom In/Out features.
