Mint ImageLoader class.

[MintPaw]

Back in the Flash Player 9 days I wanted to let the user upload images into the my flash games and let him create the players logo in my game. Sadly back then I realized it was imposable without some kind of server to hold the images.

Look like a while ago it suddenly became possible with Flash Player 10, and I never knew, but it is a bit tricky. So I took the time to write a class that people might find useful.

Links are all below, in the classes link you'll find a folder called Mint, take that folder and move it into your source folder or a class path directory. It contains ImageLoader and ImageLoaderEvent.

Here's an example of how it works:
Make sure to import import Mint.*;

//Vars
private var _imageLoader:ImageLoader;
private var _loadText:TextField;

//My init function
private function init(e:Event = null):void 
{
	removeEventListener(Event.ADDED_TO_STAGE, init);

	//Create a text box and add it to the centre of the stage.
	_loadText = new TextField();
	_loadText.text = "Load image";
	_loadText.x = stage.stageWidth / 2;
	_loadText.y = stage.stageHeight / 2;
	_loadText.selectable = false;
	addChild(_loadText);
	
	//Add an event listener to start the file load when it is clicked.
	_loadText.addEventListener(MouseEvent.CLICK, openFile);
}

private function openFile(e:MouseEvent):void 
{
	//Create an new instance of the image loader
	_imageLoader = new ImageLoader();
	//Add an event listener to listen for the upload being complete. Doesn't take really any time at all.
	//This uses the IMAGE_LOADED Event in the ImageLoaderEvent class.
	_imageLoader.addEventListener(ImageLoaderEvent.IMAGE_LOADED, displayImage);
	
	//Start the image request.
	_imageLoader.requestImage();
}

private function displayImage(e:ImageLoaderEvent):void 
{
	//Create a new Bitmap the hold the returned Bitmap.
	//The Bitmap data is returned in the event under .bitmapData, so we can get it by using e.bitmapData
	//In this case we're going to put it directly into a Bitmap.
	var bitmap:Bitmap = new Bitmap(e.bitmapData);
	//Then addChild the Bitmap.
	addChild(bitmap);
	
	//For the example's sake, move the Bitmap under the "Load Image" text so you can use it again.
	setChildIndex(bitmap, getChildIndex(_loadText));
}

This will not work if you're trying to request an image outside of a user initiated event. So ImageLoader cannot run in something like a constructor, in this case it's in a MouseEvent so it works correctly, otherwise it would be a security issue and simply fail. So do test this in a browser if you're planning on using this in a game.

Use it however you wish, no need to credit.
