access your web cam and take a snapshot using flash actionscript 3.0

In this post i will help you how to access your web cam and take a snap shot and save it as in JPEG format.

  1. Create a new flash file with name WebCam.
  2. Create a button with instance name "_capt " in the stage
  3. Then create a new actionscript 3 file with name "vido". copy and paste the following code into that and save it..
    package
    {
       
        import com.adobe.images.JPGEncoder;
            import flash.display.Bitmap;
            import flash.display.BitmapData;
            import flash.media.Video;
            import flash.media.Camera;
            import flash.display.Sprite;
            import flash.events.*;
            import flash.display.MovieClip;
            import flash.net.FileReference;
            import flash.utils.ByteArray;
            import flash.geom.Matrix;

          
            [SWF(width=640,height=480,frameRate=24)]
            public class vido extends Sprite
          
            {
                public var _camera:Camera;
                public var _video:Video;
                public var _capt:MovieClip;
                public var _snap:Bitmap;
                public var _snapContent:BitmapData;
                public var _fileRefer:FileReference;
                public var bytes:ByteArray;
              
                    public function vido()
                    {
                        _camera=Camera.getCamera();
                        _video=new Video(320,240);
                        _video.attachCamera(_camera);
                        addChild(_video);
                        _capt.addEventListener(MouseEvent.CLICK,takeCapt);
                      
                  
                    }
                    public function takeCapt(evt:MouseEvent)
                    {
                      
                        var _snapContent:BitmapData=new BitmapData(320,240, false, 0);                  
                        BitmapData(_snapContent.draw(_video));
                        var _snap:Bitmap=new Bitmap();
                        _snap.bitmapData=_snapContent;
                        addChild(_snap);
                        _snap.x = 304;
                        var jpgEncode:JPGEncoder = new JPGEncoder();
                        var bytes:ByteArray = jpgEncode.encode(_snapContent);
                        var _fileRefer=new FileReference();
                        _fileRefer.save(bytes, "image.jpeg");                  
                      
                    }
            }
          
          
    } 
5. You can download the JPEG Encoder from here
6. Goto the webcam fla and give the class name =vido.
7.Run  the flash file and take the snapshot and save it as jpeg.

Here is a simple class that loads a single JPG file and places it on the screen. After creating a new Loader and a new URLRequest, we pair them with the load command. The entire process takes only three lines of code. Then, we use addChild to add the Loader object to the stage, just like a normal display object like a Sprite: package { import flash.display.*; import flash.net.URLRequest; public class BitmapExample extends MovieClip { public function BitmapExample() { var loader:Loader = new Loader(); var request:URLRequest = new URLRequest("myimage.jpg"); loader.load(request); addChild(loader); } } } It is positioned in the upper-left corner. Because the Loader object acts like a normal display object, we can also set its x and y position to center it on the sc...

You want to store information in memmory using flash sharedObject

Local shared Objecct are to Flash what cookies are to web browsers but more so. some developers because they allow you to store large amounts of data and store and retrieve.This is mainly using for saving "username" and "Passwords". var example:SharedObject = SharedObject.getLocal( "example" ); The static getLocal( )in shared object are both created and opened for reading. You want to add data to a SharedObject use the following code. // Store a username value to the example shared object. example.data.username = "myname"; You can store several datatypes to the shared object's data property, as follows. example.data.exampleArray = new Array( "a", "b", "c" ); example.data.exampleDate = new Date(); example.data.exampleObject = { key1: "example", key2: -12, key3: null }; You want to save data in a Shared Object to the client computer. var flushResult:String = example.flush( );
