Adobe Flash image data - actionscript-3

Question

I have never worked in AS3. I want to send a screen shot of flash movie to a php file. Somewhere from internet I copied this function :
function sendSprite(sprite: Sprite, scriptLocation: String): void {
var bmpData: BitmapData = new BitmapData(sprite.width, sprite.height, true, 0xFFFFFF);
bmpData.draw(sprite);
var encodedFile: Base64Encoder = new Base64Encoder();
encodedFile.encodeBytes(PNGEncoder.encode(bmpData));
var data: URLVariables = new URLVariables();
data.fileData = encodedFile;
var request: URLRequest = new URLRequest(scriptLocation);
request.method = URLRequestMethod.POST;
request.data = data;
var loader: URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, spriteSend);
loader.addEventListener(Event.OPEN, traceEvent);
loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, traceEvent);
loader.addEventListener(IOErrorEvent.IO_ERROR, traceEvent);
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, traceEvent);
loader.addEventListener(ProgressEvent.PROGRESS, traceEvent);
try {
loader.load(request);
} catch (e: * ) {
trace("an error occured of type", e);
}
function traceEvent(e: * ): void {
trace(e);
}
function spriteSend(e: Event): void {
trace(e, "\n sprite succesfully send \n");
}
}
However I am not sure how to create a sprite object for calling the above function. Please help.

Answer 1

You can create an Spriteobject with the Sprite class:
//---Create a Sprite
var mySprite:Sprite = new Sprite();
//---Add Sprite to Display List
addChild(mySprite);
Inside this Sprite you can put any DisplayObject, for example:
//---Create the Video Object
var myVideo:Video = new Video();
mySprite.addChild(myVideo);
//---Create the NetConnection
var nc:NetConnection = new NetConnection();
nc.connect(null);
//---Create NetStream
var ns:NetStream = new NetStream(nc);
myVideo.attachNetStream(ns);
//---Play the video
ns.play("example.com/video.mp4");
Next, you could send the Spriteobject to your function and do your stuff.
