	bmd.draw(video,mtr);
	
	//保存成jpg图片
	var jpg:JPGEncoder = new JPGEncoder();
	var ba:ByteArray=jpg.encode(bmd);
	
	/*  保存成png图片
	var ba:ByteArray = PNGEncoder.encode(bmd);
	var file:File = File.desktopDirectory.resolvePath("webcam" + count++ + ".png");
	var file:File = File.documentsDirectory.resolvePath("G:\PHPnow\htdocs\phpgetpic\upload\webcam" + count++ + ".png");
	*/
	var file:File = File.applicationStorageDirectory.resolvePath("G:\\PHPnow\\htdocs\\phpgetpic\\upload\\webcam" + count++ + ".jpg");
	var fileStream:FileStream = new FileStream();
	fileStream.open(file, FileMode.WRITE);
	fileStream.writeBytes(ba);
	fileStream.close();
	
	//socket 广播出去
	//sendStr("webcam" + (count-1));
}

跟本站发布的“php获取本地图片文件并生成xml文件输出”结合加socket可实现一台电脑拍照，另一台电脑显示拍得的照片。
