Retrieve a pixel with Alpha set to 255, from a transparent image


  import flash.display.*;
  public class Main extends Sprite{
    public function Main(){

        var imgData:BitmapData = new BitmapData(20, 20, true, 0xFFFFFFFF);
        trace(imgData.getPixel32(0, 0));  // Displays: 4294967295
                                  // (original data was preserved)
