globalmapper.GetPixelColor
==========================

.. currentmodule:: globalmapper
.. py:function:: GetPixelColor (GM_LayerHandle_t32 aLayer, sint32 aRow, sint32 aCol) -> GM_Error_t32, GM_Color_t

    Retrieves the color at a given pixel location from the provided raster layer. If the layer does not contain a valid
    color value at the provided pixel location (i.e. it is a "no data" or transparent value), GM_Error_NoDataAtLocation
    will be returned.

    :param GM_LayerHandle_t32 aLayer: Layer to get color from
    :param sint32 aRow: Y coord of pixel (0 is topmost)
    :param sint32 aCol: X coord of pixel (0 is leftmost)
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: Color of pixel at location
    :rtype: GM_Color_t
