.. note::
    This format cannot be automatically recognized, so the
    class is not registered for use with :py:func:`PIL.Image.open()`.  To open a
    gd file, use the :py:func:`PIL.GdImageFile.open()` function instead.

.. warning::
    THE GD FORMAT IS NOT DESIGNED FOR DATA INTERCHANGE.  This
    implementation is provided for convenience and demonstrational
    purposes only.

    Image plugin for the GD uncompressed format.  Note that this format
    is not supported by the standard :py:func:`PIL.Image.open()` function.  To use
    this plugin, you have to import the :py:mod:`PIL.GdImageFile` module and
    use the :py:func:`PIL.GdImageFile.open()` function.
