Answer 1

actually, you can use back2dos 's solution in a much easier way:

const rc:Number = 1/3, gc:Number = 1/3, bc:Number = 1/3;
mc.filters = [ new ColorMatrixFilter([rc, gc, bc, 0, 0,rc, gc, bc, 0, 0, rc, gc, bc, 0, 0, 0, 0, 0, 1, 0]) ];

where mc is the MovieClip or Sprite container where the bitmapdata exists as a visual element. thanks back2dos :)
