8.2.0

Deprecations
============

Tk/Tcl 8.4
^^^^^^^^^^

Support for Tk/Tcl 8.4 is deprecated and will be removed in Pillow 10.0.0 (2023-01-02),
when Tk/Tcl 8.5 will be the minimum supported.

API Changes
===========

Image.alpha_composite: dest
^^^^^^^^^^^^^^^^^^^^^^^^^^^

When calling :py:meth:`~PIL.Image.Image.alpha_composite`, the ``dest`` argument now
accepts negative co-ordinates, like the upper left corner of the ``box`` argument of
:py:meth:`~PIL.Image.Image.paste` can be negative. Naturally, this has effect of
cropping the overlaid image.

Image.getexif: EXIF and GPS IFD
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Previously, :py:meth:`~PIL.Image.Image.getexif` flattened the EXIF IFD into the rest of
the data, losing information. This information is now kept separate, moved under
``im.getexif().get_ifd(0x8769)``.

Direct access to the GPS IFD dictionary was possible through ``im.getexif()[0x8825]``.
This is now consistent with other IFDs, and must be accessed through
``im.getexif().get_ifd(0x8825)``.

These changes only affect :py:meth:`~PIL.Image.Image.getexif`, introduced in Pillow
6.0. The older ``_getexif()`` methods are unaffected.

API Additions
=============

ImageDraw.rounded_rectangle
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Added :py:meth:`~PIL.ImageDraw.ImageDraw.rounded_rectangle`. It works the same as
:py:meth:`~PIL.ImageDraw.ImageDraw.rectangle`, except with an additional ``radius``
argument. ``radius`` is limited to half of the width or the height, so that users can
create a circle, but not any other ellipse.

.. code-block:: python

    from PIL import Image, ImageDraw
    im = Image.new("RGB", (200, 200))
    draw = ImageDraw.Draw(im)
    draw.rounded_rectangle(xy=(10, 20, 190, 180), radius=30, fill="red")

ImageShow.IPythonViewer
^^^^^^^^^^^^^^^^^^^^^^^

If IPython is present, this new :py:class:`PIL.ImageShow.Viewer` subclass will be
registered. It displays images on all IPython frontends. This will be helpful
to users of Google Colab, allowing ``im.show()`` to display images.

It is lower in priority than the other default :py:class:`PIL.ImageShow.Viewer`
instances, so it will only be used by ``im.show()`` or :py:func:`.ImageShow.show()`
if none of the other viewers are available. This means that the behaviour of
:py:class:`PIL.ImageShow` will stay the same for most Pillow users.

Saving TIFF with ICC profile
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

As is already possible for JPEG, PNG and WebP, the ICC profile for TIFF files can now
be specified through a keyword argument::

    im.save("out.tif", icc_profile=...)

Security
========

TODO

Other Changes
=============

PyQt6
^^^^^

Support has been added for PyQt6. If it is installed, it will be used instead of
PySide6, PyQt5 or PySide2.
