   Very nice example, but i have trouble:
   when i’m trying to flip object with text (i.e. label, button) I don’t see text after flipping.
   After appplying flip once more, text appear back.
   Any suggestions ?

   ah…
   sorry
   If you want to do something like flip with objects with text, you must use embed fonts.

   Yes, otherwise the fonts aren’t eligible to be rasterized into bitmaps.

   Hi, I´m not sure what your code does, but I think it´s easier like this:

   vertical:
   dsp.scaleY = -dsp.scaleY;

   horizontal:
   dsp.scaleX = -dsp.scaleX;

   xleon,

   Your method doesn’t work with video, while the others do.

   to switch back and forth, use this:

   function flipHorizontal(dsp:DisplayObject):void
   {
   var matrix:Matrix = dsp.transform.matrix;
   //matrix.a = -1;
   matrix.a *= -1;
   //matrix.tx = dsp.width + dsp.x;
   matrix.tx = -matrix.a * dsp.width + dsp.x;
   dsp.transform.matrix = matrix;
   }

   function flipVertical(dsp:DisplayObject):void
   {
   var matrix:Matrix = dsp.transform.matrix;
   //matrix.d = -1;
   matrix.d *= -1;
   matrix.ty = -matrix.d * dsp.height + dsp.y;
   //matrix.ty = dsp.height + dsp.y;
   dsp.transform.matrix = matrix;
   }

   Does anyone know how the Michael’s code woulde be if the image had a bigger or smaller scale and a rotation angle?
