Ok so lets save this image then….

There are a few more things we need to add to our little application file.
We need to import a jpeg encoder and a few filesystem classes. So underneath the other importing statements we add the following code:

                          import mx.graphics.codec.JPEGEncoder;
                     import flash.filesystem.File; 
                    import flash.filesystem.FileMode;
                         import flash.filesystem.FileStream;
 

We also need to add a call to a new function to save the image. We will add this to the takeSnapshot function. The take snapshot function will now look like this:

 public function takeSnapshot():void{
      var snapshotHolder:UIComponent = new UIComponent();
      var snapshot:BitmapData = new BitmapData(160,120, true);
      var snapshotbitmap:Bitmap = new Bitmap(snapshot);     
  
      snapshotHolder.addChild(snapshotbitmap);
      cnvSnapshot.addChild(snapshotHolder);
      snapshot.draw(video);
      saveImg(snapshot);
  }
 

Finally we add the saveImg() function.

 private function saveImg( imgData:BitmapData ):void{
     /* Create the necessary objects */
      var imgEncoder:JPEGEncoder = new JPEGEncoder( 99 );      
      var fileStream:FileStream = new FileStream();
      var myDate:Date = new Date();  
   /* Create the unique file name */
      var thisFileName:String = “webcam_”+ myDate.getTime() +”.jpg”;
    
     /* Create the a file object for the new file */
  
      var theFile:File = File.desktopDirectory.resolve( thisFileName ); 
   /* Get the image data and store it in a byte array */
      var iBytesA:ByteArray = imgEncoder.encode(imgData) ;        
   /* Open the file and write the data to the file */
      fileStream.openAsync(theFile, FileMode.WRITE);
      fileStream.writeBytes( iBytesA ); 
   /* Close the file */ 
      fileStream.close();
    }
 

Next on our to do list is to add a timer function to periodically take pictures…
