SnapIt Apollo – Source Included

I have had requests on how to take snap shot and save it to disk.  So here is a vary basic example that takes a picture of itself and saves it to disk using the file name provided.  Here is the guts of the function that saves the image:

private function snagPic():void {
bitmapData = new BitmapData(this.width,this.height);
bitmapData.draw(this,new Matrix());
var bitmap : Bitmap = new Bitmap(bitmapData);
var jpg:JPGEncoder = new JPGEncoder();
var ba:ByteArray = jpg.encode(bitmapData);
newImage = File.appStorageDirectory.resolve(“Images/” + fileName.text + “.jpg”);
fileStream = new FileStream();
fileStream.open(newImage, FileMode.UPDATE);
fileStream.writeBytes(ba);
}

Please note you will need the core lib for the image encoders if you want to compile it yourself.

Apollo Online/Offline sample – full source included

Here is a nice little example of testing for online and offline within Apollo. It is very basic.

Test it by either hitting the Test Connection button or by pulling your cable on disconnecting your wireless.

Here is what is occurring within the application:

• on creationComplete Shell.shell.addEventListener(Event.NETWORK_CHANGE,onNetworkChange);
• onNetworkChange test the connection. Here is the contents of the test connection function.
  • var headRequest:URLRequest = new URLRequest();
    headRequest.method = “HEAD”;
    headRequest.url = “http://blog.everythingflex.com”;
    var response:URLLoader = new URLLoader(headRequest);
    response.addEventListener(HTTPStatusEvent.HTTP_STATUS,statusChanged);
    response.addEventListener(IOErrorEvent.IO_ERROR,error);
• when the HTTPStatusEvent.HTTP_STATUS Event is broadcast statusChanged is called
  • The statusChanged fuction checks the status code and sets disconnected if code is 0
• if IOErrorEvent.IO_ERROR is broadcast
  • we assume the connection is broken

Thats it. There are additional URLLoader events that can be checked but I haven’t included them in this example. Check the documentation for details on these events. Here is the results:
