globalmapper.ConvertCoordLayerGroundToPixel
===========================================

.. currentmodule:: globalmapper
.. py:function:: ConvertCoordLayerGroundToPixel (GM_LayerHandle_t32 aLayer, float aGroundX, float aGroundY) -> GM_Error_t32, float, float

    Convert a coordinate between the current projection and layer pixel space and the current. The input layer must be a
    raster or gridded elevation layer (i.e. a layer where a pixel coordinate makes sense).

    :param GM_LayerHandle_t32 aLayer: raster layer to do conversion in
    :param float aGroundX: X Coord in current projection
    :param float aGroundY: Y Coord in current projection
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: X Coord in layer pixel space
    :rtype: float
    :return: Y Coord in layer pixel space
    :rtype: float
