Getting the mouse position in pixels in QC

Hi,

I'm trying to make something that can get the mouse position in pixels in quartz composer using "rendering destination dimensions" and "mouse". The idea is to dynamically be able to know if the mouse is over a specific image or not.

If i have the mouse at 1/4 of the screen, the "opengl position" or whatever it's called is -0.5, how can i use this to get the actual pixel position?

Thanks
