globalmapper.GetLastDrawnScale
==============================

.. currentmodule:: globalmapper
.. py:function:: GetLastDrawnScale (HDC aDC) -> float

    .. note:: This function requires a Handle to Device Context (HDC), which comes from the Windows GUI. An HDC for a window is easy to get in C++, but unobtainable in Python without relying on other modules. As such, you may be unable to use this and other functions which need an HDC as parameter; they are included in the Python SDK for Global Mapper primarily for consistency with the C++ version of the SDK and are not fully supported at current release.

    Return the scale value (i.e. 24000.0 for 1:24K) that data was last rendered at. If nothing has been drawn, 0.0 is returned.

    :param HDC aDC: Device context that was drawn to
    :returns: The scale value
    :rtype: float
