globalmapper.GetPathProfile
===========================

.. currentmodule:: globalmapper
.. py:function:: GetPathProfile (GM_LayerHandle_t32 aLayer, float aStartX, float aStartY, float aEndX, float aEndY, float_array aElevList, int aListSize, float aDfltElev) -> GM_Error_t32

    Retrieves a list of elevations along a path in the provided layer or from the list of currently loaded elevation
    layers (topmost elevation layer first). The result is returned into the *aElevList* parameter as a float_array.
	
    :param GM_LayerHandle_t32 aLayer: Layer to get elevation from or gm.NULL for topmost
    :param float aStartX: Start X coord in current projection
    :param float aStartY: Start Y coord in current projection
    :param float aEndX: End X coord in current projection
    :param float aEndY: End Y coord in current projection
    :param float_array aElevList: Buffer to hold list of elevations; must be initialized before using as a parameter
    :param int aListSize: Number of elevations to retrieve; must not be greater than length of *aElevList*
    :param float aDfltElev: Elev to use when none could be found
    :returns: Error Code
    :rtype: GM_Error_t32
