Uploading an image dynamically into Flash

Question

I'd upload an image choosen by the client, but I want to wrap it in a movieclip in order to manipulate its size and color with color transform. How can I do it? (AS3 in Flash 10)
My code:
import flash.display.SimpleButton;
   import flash.net.FileReference;
   import flash.net.FileFilter;
   import flash.events.IOErrorEvent;
   import flash.events.Event;
   import flash.utils.ByteArray;
   import flash.display.*;
   import flash.geom.*;
   var loadFileRef:FileReference;
   const FILE_TYPES:Array = [new FileFilter("Image Files", "*.jpg;*.jpeg;*.gif;*.png;*.JPG;*.JPEG;*.GIF;*.PNG")];
    function loadFile(event:MouseEvent):void {
    loadFileRef = new FileReference();
    loadFileRef.addEventListener(Event.SELECT, onFileSelect);
    loadFileRef.browse();
    function onFileSelect(e:Event):void {
    loadFileRef.addEventListener(Event.COMPLETE, onFileLoadComplete);
    loadFileRef.load();
    function onFileLoadComplete(e:Event):void {
       var loader:Loader = new Loader();
       loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDataLoadComplete);
       loader.loadBytes(loadFileRef.data);
    loadFileRef = null;
    function onDataLoadComplete(e:Event):void {
    var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData;
    if((bitmapData.height)<=(bitmapData.width))
                var r:Number = bitmapData.height/bitmapData.width;
                var ra:Number = 500*r;
                var matrix:Matrix = new Matrix();
                matrix.scale(500/bitmapData.width, ra/bitmapData.height);
    graphics.clear();
    graphics.lineStyle(1, 0x000000);
    graphics.beginBitmapFill(bitmapData, matrix, false);
    graphics.drawRect(0, 0, 500, ra);
    graphics.endFill();
    } else {
                var d:Number = bitmapData.width/bitmapData.height;
                var da:Number = 500*d;
                var matrix2:Matrix = new Matrix();
                matrix2.scale(500/bitmapData.width, da/bitmapData.height);
    graphics.clear();
    graphics.lineStyle(1, 0x000000);
    graphics.beginBitmapFill(bitmapData, matrix2, false);
    graphics.drawRect(0,50, 500, da);
    graphics.endFill();
  boton.addEventListener(MouseEvent.CLICK, loadFile);
Any help will be very appreciated. Madrid.

Answer 1

If you see the code, I draw a rectangle in order to enclose the bitmapData as a fill. I made it in flex adding the rectangle to a canvas with ID, and then applied the transformations and zooming to the canvas itself successfully. But my client wants some other issues that only can be made in Flash, and I have to transfer the whole code to Flash, For instance, look at both codes and you will grasp what I'm trying to say:
1) Flex:
imageView.graphics.clear();  // "imageView" is the canvas id.imageView.graphics.beginBitmapFill(bitmapData, matrix,false);imageView.graphics.drawRect(0, 0, 500, ra);
imageView.graphics.endFill();
2) Flash:
     graphics.clear();   // you see? There is NOT an instance name. How can I manipulate THIS?
    graphics.lineStyle(1, 0x000000);
    graphics.beginBitmapFill(bitmapData, matrix, false);
    graphics.drawRect(0, 0, 500, ra);
    graphics.endFill();
Thanks a lot for your patience. Madrid.
