project method

Future<MercatorCoordinate> project(Point coordinate, double zoomScale)

Calculate a point on the map in Mercator Projection for a given coordinate at the specified zoom scale.

@param coordinate The longitude-latitude pair for which to return the value. @param zoomScale The current zoom factor (2 ^ Zoom level) applied on the map, is used to calculate the world size as tileSize * zoomScale (i.e., 512 * 2 ^ Zoom level) where tileSize is the width of a tile in pixels.

@return Returns a point on the map in Mercator projection.
