========================

.. currentmodule:: globalmapper
.. py:function:: CalcBearing (float aFromX, float aFromY, float aToX, float aToY, GM_CalcBearingFlags_t8 aFlags) -> GM_Error_t32, float

    Calculates the bearing in radians between two points. The points can either be specified as lat/lon values or in the
    current projection. The bearing retrieved is a cartographic bearing, with 0 being north, PI / 2 being east, PI being
    south, and 3 * PI / 2 being west.

    :param float aFromX: start X/longitude coordinate
    :param float aFromY: start Y/latitude coordinate
    :param float aToX: stop X/longitude coordinate
    :param float aToY: stop Y/latitude coordinate
    :param GM_CalcBearingFlags_t8 aFlags: flags controlling coordinate projection and returned bearing sense
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: Bearing in radians between the points
    :rtype: float
