◆ geoCoordinates()
|
overridevirtual |
Get the earth coordinates corresponding to a pixel in the map.
- Parameters
-
x the x coordinate of the pixel y the y coordinate of the pixel params parameters of the viewport lon the longitude angle is returned through this parameter lat the latitude angle is returned through this parameter unit the unit
- Returns
true
if the pixel (x, y) is within the globefalse
