The function LatLon2XY.centered(MyMap, lat,lon,zoom) computes the coordinate transformation from lat/lon to map tile coordinates given a map object.
LatLon2XY.centered(MyMap, lat, lon, zoom)
map object
latitude values to transform
longitude values to transform
optional zoom level. If missing, taken from MyMap
properly scaled and centered (with respect to the center of MyMap
) coordinates
transformed longitude
transformed latitude
