: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.

.. class:: wx.adv.GIFDecoder(AnimationDecoder)

   **Possible constructors**::

       GIFDecoder()
       
   
   An animation decoder supporting animated ``GIF`` files.



   .. method:: __init__(self)






   .. method:: Clone(self)

      Create a copy of this decoder.                  

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








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

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

      :type `frame`: int
      :param `image`: 
      :type `image`: wx.Image




      :rtype: `bool`








   .. method:: DoCanRead(self, stream)

      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:`~wx.adv.AnimationDecoder.CanRead`   will do it.

      :type `frame`: int




      :rtype: `Colour`     








   .. method:: GetType(self)

      Return the animation type this decoder implements.                  

      :rtype: :ref:`wx.adv.AnimationType`








   .. method:: Load(self, stream)

      Load the animation image frames from the given stream.
