Conversion Lat/Long to Screen-Pixels

Hi,
I have add a Place on the map and I try to get the Position in Screen-Pixels from that Place.
Is there any way to do that..?

I try with the "com.nutiteq.maps.projections"-package, but there is only conversions from Wgs-to-Map-Point/Map-Point-to-Wgs but I need the position in pixels..!
