.. _wx.Metafile:

==========================================================================================================================================
|phoenix_title|  **wx.Metafile**
==========================================================================================================================================

A  ** :ref:`wx.Metafile` **   represents the MS Windows metafile object, so metafile operations have no effect in X.          

In wxWidgets, only sufficient functionality has been provided for copying a graphic to the clipboard; this may be extended in a future version. 

Presently, the only way of creating a metafile is to use a :ref:`wx.MetafileDC`.

.. class:: wx.Metafile(Object)

   **Possible constructors**::

       Metafile(filename="")
       
   
   A Metafile represents the MS Windows metafile object, so metafile
   operations have no effect in X.



   .. method:: __init__(self, filename="")

      Constructor.                  

      If a filename is given, the Windows disk metafile is read in. Check whether this was performed successfully by using the :meth:`IsOk`   member.                  


      :param `filename`: 
      :type `filename`: string







   .. method:: IsOk(self)

      Returns ``True`` if the metafile is valid.                  

      :rtype: `bool`








   .. method:: Play(self, dc)

      Plays the metafile into the given device context, returning ``True`` if successful.                  


      :param `dc`: 
      :type `dc`: wx.DC




      :rtype: `bool`








   .. method:: SetClipboard(self, width=0, height=0)

      Passes the metafile data to the clipboard.                  

      The metafile can no longer be used for anything, but the :ref:`wx.Metafile`  object must still be destroyed by the application. 

      Below is an example of metafile, metafile device context and clipboard use from the  ``hello.cpp``   example. Note the way the metafile dimensions are passed to the clipboard, making use of the device context's ability to keep track of the maximum extent of drawing commands. 

      ::

          dc = wx.MetafileDC()
          if dc.IsOk():
              self.Draw(dc)
              mf = dc.Close()
              if mf:
                  mf.SetClipboard(dc.MaxX() + 10, dc.MaxY() + 10)

                 


      :param `width`: 
      :type `width`: int
      :param `height`: 
      :type `height`: int




      :rtype: `bool`
