Flash/Flex学习笔记(2)：捕获摄像头
Flash中使用摄像头，个人感觉比silverlight要更容易
时间轴第一帧上敲以下代码就可以了：
//import fl.controls.Label;??
???
//var camera:Camera = Camera.getCamera();??
??
//trace(camera==null?"未检测到摄像头":"已安装了摄像头");??
??
var W:int=stage.stageWidth;//场景的原始宽度??
????
var H:int=stage.stageHeight;//场景的原始高度??
????
stage.scaleMode=StageScaleMode.NO_SCALE;//舞台禁止缩放,但是好
象没效果???
???
var video:Video;??
???
var camera:Camera=Camera.getCamera();??
???
if (camera==null) {??
??
trace("未检测到摄像头!");????
????
lbl1.text="未检测到摄像头!";??
???
btnCapture.visible=false;??
??
} else {??
????
camera.addEventListener
(ActivityEvent.ACTIVITY,activityHander);??
??
video=new Video(camera.width,camera.height);??
??
trace("视频宽度：" + camera.width + "，视频高度：" +
camera.height);??
???
video.attachCamera(camera);??
???
//定位到水平中心点??
video.x = (W - video.width) /2;??
???
video.y=10;??
???
addChild(video);//加载到当前舞台中??
??
btnCapture.x = (W - btnCapture.width) /2;??
??
btnCapture.y=video.y+video.height+5;??
??
btnCapture.addEventListener(MouseEvent.CLICK,captureImage);??
??
}??
??
???
function activityHander(e:ActivityEvent):void {??
???
trace("activityHander:" + e);??
??
}??
??
var dp:DataProvider = new DataProvider();??
??
function captureImage(e:MouseEvent):void {??
???
//trace("你点击了按钮");??
?
var bit:BitmapData=new BitmapData(video.width,video.height);??
???
bit.draw(video);??
???
var bmp:Bitmap=new Bitmap(bit);??
?
//bmp.y=btnCapture.y+btnCapture.height+10;??
?
//bmp.x = (W - bmp.width) /2;??
???
var d:Date = new Date();??
??
dp.addItem({label:"截图" + d.getFullYear() + d.getMonth() +
d.getDay() + d.getHours() + d.getMinutes() + d.getSeconds() +
d.getMilliseconds(),source:bmp});??
?
//addChild(bmp);??
???
tilelst1.dataProvider = dp;??
?
}??
??
stop();
