		const int	y,
		qreal &	lon,
		qreal &	lat,
		GeoDataCoordinates::Unit	unit = `GeoDataCoordinates::Degree`
	)		const

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
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 false if the pixel (x, y) is outside the globe, i.e. in space.

bool Marble::ViewportParams::screenCoordinates	(	const qreal	lon,
		const qreal	lat,
		qreal &	x,
		qreal &	y
	)		const

Get the screen coordinates corresponding to geographical coordinates in the map.

Parameters

lon	the lon coordinate of the requested pixel position in radians
lat	the lat coordinate of the requested pixel position in radians
x	the x coordinate of the pixel is returned through this parameter
y	the y coordinate of the pixel is returned through this parameter

Returns: true if the geographical coordinates are visible on the screen false if the geographical coordinates are not visible on the screen

		bool &	globeHidesPoint
	)		const

Get the screen coordinates corresponding to geographical coordinates in the map.

Parameters

geopoint	the point on earth, including altitude, that we want the coordinates for.
x	the x coordinate of the pixel is returned through this parameter
y	the y coordinate of the pixel is returned through this parameter
globeHidesPoint	whether the point gets hidden on the far side of the earth

Returns: true if the geographical coordinates are visible on the screen false if the geographical coordinates are not visible on the screen

		bool &	globeHidesPoint
	)		const

Get the coordinates of screen points for geographical coordinates in the map.

Parameters

coordinates	the point on earth, including altitude, that we want the coordinates for.
x	the x coordinates of the pixels are returned through this parameter
y	the y coordinate of the pixel is returned through this parameter
pointRepeatNum	the amount of times that a single geographical point gets represented on the map
globeHidesPoint	whether the point gets hidden on the far side of the earth

Returns: true if the geographical coordinates are visible on the screen false if the geographical coordinates are not visible on the screen
