[Mapserver-users] center map on x,y coordinates

[Alexandros Chimarios]

Hi , 

	are you using the MapScript language ? If yes in the mapObj class there is 
the method centerByPoint which operates on the screen space(pixels). What are 
those x,y ? Screen coords(pixels) or geographical coordinates (e.x lat/lon) ?
