Here's another method that would allow you to pass in the whole UIComponent.  
Below is an example usage:

public function getUIComponentBitmapData( target:UIComponent, w:Number, 
h:Number ) : BitmapData
{ 
    // scale down (or up)
    var scaleX:Number = w / target.width;
    var scaleY:Number = h / target.height;
    var m:Matrix = new Matrix();
    m.scale(scaleX, scaleY);

    // get new bitmap data
    var bd:BitmapData = new BitmapData( w, h );
    bd.draw( target, m );
    bd.smoothing = true;

    // return the new bitmap data
    return bd;  
}



Assume you have var originalImage:Image already set and you want to scale it 
down to 50x30:

var newImage:Image = new Image();
newImage.source = getUIComponentBitmapData( originalImage, 50, 30 );
