Batch processing
^^^^^^^^^^^^^^^^
Operations can be applied to multiple image files. For example, all PNG images
in the current directory can be saved as JPEGs at reduced quality.
::
import glob
from PIL import Image
def compress_image(source_path, dest_path):
with Image.open(source_path) as img:
if img.mode != "RGB":
img = img.convert("RGB")
img.save(dest_path, "JPEG", optimize=True, quality=80)
paths = glob.glob("*.png")
for path in paths:
compress_image(path, path[:-4] + ".jpg")
Since images can also be opened from a ``Path`` from the ``pathlib`` module,
the example could be modified to use ``pathlib`` instead of the ``glob``
module.
::
from pathlib import Path
paths = Path(".").glob("*.png")
for path in paths:
compress_image(path, path.stem + ".jpg")

9.0.0
-----
Fredrik Lundh
=============
This release is dedicated to the memory of Fredrik Lundh, aka Effbot, who died in
November 2021. Fredrik created PIL in 1995 and he was instrumental in the early
success of Python.
`Guido wrote <https://mail.python.org/archives/list/python-dev@python.org/thread/36Q5QBILL3QIFIA3KHNGFBNJQKXKN7SD/>`_:
Fredrik was an early Python contributor (e.g. Elementtree and the 're'
module) and his enthusiasm for the language and community were inspiring
for all who encountered him or his work. He spent countless hours on
comp.lang.python answering questions from newbies and advanced users alike.
He also co-founded an early Python startup, Secret Labs AB, which among
other software released an IDE named PythonWorks. Fredrik also created the
Python Imaging Library (PIL) which is still THE way to interact with images
in Python, now most often through its Pillow fork. His effbot.org site was
a valuable resource for generations of Python users, especially its Tkinter
documentation.
Thank you, Fredrik.

ImageShow.XDGViewer
^^^^^^^^^^^^^^^^^^^
If ``xdg-open`` is present on Linux, this new :py:class:`PIL.ImageShow.Viewer` subclass
will be registered. It displays images using the application selected by the system.
It is higher in priority than the other default :py:class:`PIL.ImageShow.Viewer`
instances, so it will be preferred by ``im.show()`` or :py:func:`.ImageShow.show()`.
Added support for "title" argument to DisplayViewer
