API Changes
|
|
===========
|
|
|
|
Allow saving of zero quality JPEG images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
If no quality was specified when saving a JPEG, Pillow internally used a value
|
|
of zero to indicate that the default quality should be used. However, this
|
|
removed the ability to actually save a JPEG with zero quality. This has now
|
|
been resolved.
|
|
|
|
.. code-block:: python
|
|
|
|
from PIL import Image
|
|
im = Image.open("hopper.jpg")
|
|
im.save("out.jpg", quality=0)
|
|
|
|
Improved APNG support
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Added support for reading and writing Animated Portable Network Graphics (APNG) images.
|
|
The PNG plugin now supports using the :py:meth:`~PIL.Image.Image.seek` method and the
|
|
:py:class:`~PIL.ImageSequence.Iterator` class to read APNG frame sequences.
|
|
The PNG plugin also now supports using the ``append_images`` argument to write APNG frame
|
|
sequences. See :ref:`apng-sequences` for further details.
