:meth:`~wx.adv.AnimationDecoder.__init__`                                        
:meth:`~wx.adv.AnimationDecoder.CanRead`                                         Returns ``True`` if this decoder supports loading from the given stream.
:meth:`~wx.adv.AnimationDecoder.Clone`                                           Create a copy of this decoder.
:meth:`~wx.adv.AnimationDecoder.ConvertToImage`                                  Convert given frame to  :ref:`wx.Image`.
:meth:`~wx.adv.AnimationDecoder.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:`~AnimationDecoder.CanRead`   will do it.
