flex - Converting button Icon back to Image -

-

I want to remove the button icon image as a flex image component, then change it to filter it Apply to / white and then apply the image to another button as an icon. Any ideas how can I do this? So far, I can get this as an object in the form of an object: 

  var iconImg: Object = myBtn.getStyle ("icon");

It is not certain how to convert that object into an image.

IconImage object type is DisplayObject so you can draw in a bitmap data object, then apply the transformation You can do this and set the 'icon' style of the second button in this new transfiled object.
