[Chameleon] GeoToPixel Function

[Ken Sanderson]

By mapObject's zoomtopoint do you mean mapscript's zoompoint function? 
If so it takes its coordinates in pixels I believe.

Are you creating a widget or where are you trying to access the coords? 
Have you tried grabbing the X and Y values from the form hidden 
variables MAP_CURSOR_POS_X and MAP_CURSOR_POS_Y, these values would be 
in pixels?
