globalmapper.SetOrientation
===========================

.. currentmodule:: globalmapper
.. py:function:: SetOrientation (float aOrientation) -> GM_Error_t32

    Allows for drawing data with a direction other than north to the top of the screen for most projections. A value of
    0.0 is the default and implies no rotation. Technically, the orientation value is the number of degrees to rotate
    the rendered data counter-clockwise.

    :param float aOrientation: Orientation of bitmap (0 is north up, 90 is east up, 180 is south up, 270 is west up)
    :returns: Error Code
    :rtype: GM_Error_t32
