:meth:`~wx.adv.GIFDecoder.ConvertToImage`                                        Convert given frame to  :ref:`wx.Image`.
:meth:`~wx.adv.GIFDecoder.DoCanRead`                                             Checks the signature of the data in the given stream and returns ``True`` if it appears to be a valid animation format recognized by the animation decoder; this function should modify the stream current position without taking care of restoring it since  :meth:`~GIFDecoder.CanRead`   will do it.
:meth:`~wx.adv.GIFDecoder.GetDelay`                                              Return the number of milliseconds this frame should be displayed.

   .. method:: __init__(self)



      :rtype: `None`     








   .. method:: Clone(self)

      Create a copy of this decoder. 
                 

      :rtype: :ref:`wx.adv.AnimationDecoder`








   .. method:: ConvertToImage(self, frame : int, image : Image)

      Convert given frame to  :ref:`wx.Image`.
