Flash AS3 Color Correction

I will soon need a wig to replace the hair I've ripped out in regards to this problem! I have a flash element on my website that is an XML gallery. It's supposed to blend seamlessly in with the background. I imported a PNG that has transparency which one edge is the blending edge with the other BG. Of course there's a color shift on both Mac and Windows. I tried importing PSD, saving as JPG, using GammaSlamma to remove profiling, all sorts of stuff.

I thought I was going to have to manually adjust the image to match and then serve two different Flash files depending on the user's OS or something crazy like that, but then I saw that AS3 supports color correction and a lot of people have seemed to find it useful. Needless to say I was very excited However, I've NEVER used AS3 before, and am developing a major headache over it.

I found a replacement free slideshow that's AS3 but I just have no idea where to add this code in.

Code that according to http://kelsocartography.com/blog/?tag=as3-color-correction is all that's needed:

stage.colorCorrection = ColorCorrection.ON;

The code for the gallery (sorry for such a long snippet):

You can see I added "color correction" in there, but get this error when I run the file:

ReferenceError: Error #1065: Variable stage is not defined.
at global$init()

Any suggestions? Thank you....

That's because the stage is not defined/created yet. So here are 2 options:

1. Use the ADDED_TO_STAGE listener to wait for the slideshow to be added to the stage. So you'd have add the following to the constructor:

   addEventListener(Event.ADDED_TO_STAGE,
   

   _added); And add this function to the class:

   private _added function(e:Event)
   {
     removeEventListener(Event.ADDED_TO_STAGE,
   

   _added); stage.colorCorrection = ColorCorrection.ON; }

2. Make a document class (see http://goo.gl/b92SU for a tut on these) for your flash like so:

   package
   {
     import flash.display.MovieClip;
   
     public class Main extends MovieClip
     {
       function Main()
       {
         addEventListener(Event.ADDED_TO_STAGE, _added);
         //other code that was in your main timeline
       }
   
       private function _added(e:Event):void
       {
         removeEventListener(Event.ADDED_TO_STAGE, _added);
         stage.colorCorrection = ColorCorrection.ON;
       }
     }
   }
   

You can't put code outside a class. Remove the line

stage.colorCorrection = ColorCorrection.ON;

And place it on your Document Class constructor. If you have trouble with that, means that your application is not properly set. I'd recommend you to create a new question, or read this tutorial.
