The scaling of the map

To change the map's scale along the point, induce the following functions:

var wspol = map.getCenterPos(); //Assign the current coordinates of the 
                                //middle point of the map for a variable "wspol"

map.setCenterPos(new EMAPI.LonLat(wspol),10); //substitution of the current coordinates 
                                              //and a new value of the scale

EMAPI.LonLat

EMAPI.LonLat(lon,lat);

gdzie:

lon	{Number} Longitude.
lat	{Number} Latitude.
