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();
