我有代码可以在我的 swf 中创建舞台的实时屏幕截图。之后，它保存为 jpeg。都好。

只是，我不需要整个舞台，我只需要一个抠图：

x,y：357,341 宽度，高度：319,483

我的代码看起来像这样..

在哪里以及如何插入 copypixels 函数？

（我是 Flash 新手，所以请放轻松 :-)

function mouseReleaseSave(event:MouseEvent):void {
import com.adobe.images.JPGEncoder;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequestHeader;
import flash.net.URLRequest;

var jpgSource:BitmapData = new BitmapData(this.stage.stageWidth, this.stage.stageHeight);
jpgSource.draw(this.stage);
var jpgEncoder:JPGEncoder = new JPGEncoder(70);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

//set the request's header,method and data
var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");
var loader:URLLoader = new URLLoader();
//sends jpg bytes to saveJPG.php script
var myRequest:URLRequest = new URLRequest("saveJPG.php");
myRequest.requestHeaders.push(header);
myRequest.method = URLRequestMethod.POST;
myRequest.data = jpgStream;
loader.load(myRequest);
//fire complete event;
loader.addEventListener(Event.COMPLETE,saved);
function saved(e:Event){
    //trace the image file name
    trace(loader.data);
}

}

这应该有助于：

var subArea:Rectangle = new Rectangle(0,0, 319,483 );
var newBmp:Bitmap = new BitmapData( 319,483 );
var cutoutBmp:Bitmap = new Bitmap( newBmp, PixelSnapping.ALWAYS, true );
cutoutBmp.bitmapData.draw( jpgSource, new Matrix(1, 0, 0, 1, -357, -341) , null, null, subArea, true );
