- Abstract method:
- This method is abstract and can be overridden but not called directly.
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 viewport the viewport parameters lon the longitude angle is returned through this parameter lat the latitude angle is returned through this parameter unit the unit of the angles for lon and lat.
- Returns:
- true if the pixel (x, y) is within the globe
