GifImagePlugin loading strategy
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Pillow 9.0.0 introduced the conversion of subsequent GIF frames to ``RGB`` or ``RGBA``. This
behaviour can now be changed so that the first ``P`` frame is converted to ``RGB`` as
well.
.. code-block:: python
from PIL import GifImagePlugin
GifImagePlugin.LOADING_STRATEGY = GifImagePlugin.LoadingStrategy.RGB_ALWAYS
Or subsequent frames can be kept in ``P`` mode as long as there is only a single
palette.
.. code-block:: python
from PIL import GifImagePlugin
GifImagePlugin.LOADING_STRATEGY = GifImagePlugin.LoadingStrategy.RGB_AFTER_DIFFERENT_PALETTE_ONLY
