Deprecations and removals
=========================
This page lists Pillow features that are deprecated, or have been removed in
past major releases, and gives the alternatives to use instead.
Deprecated features
-------------------
Below are features which are considered deprecated. Where appropriate,
a ``DeprecationWarning`` is issued.
2021-06-30 13:57:21 +03:00
Tk/Tcl 8.4
~~~~~~~~~~
.. deprecated:: 8.2.0
Support for Tk/Tcl 8.4 is deprecated and will be removed in Pillow 10.0.0 (2023-07-01),
2021-06-30 13:57:21 +03:00
when Tk/Tcl 8.5 will be the minimum supported.
Categories
~~~~~~~~~~
.. deprecated:: 8.2.0
``im.category`` is deprecated and will be removed in Pillow 10.0.0 (2023-07-01),
2021-06-30 13:57:21 +03:00
along with the related ``Image.NORMAL``, ``Image.SEQUENCE`` and
``Image.CONTAINER`` attributes.
To determine if an image has multiple frames or not,
``getattr(im, "is_animated", False)`` can be used instead.
2021-06-30 14:47:41 +03:00
JpegImagePlugin.convert_dict_qtables
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 8.3.0
JPEG ``quantization`` is now automatically converted, but still returned as a
dictionary. The :py:attr:`~PIL.JpegImagePlugin.convert_dict_qtables` method no longer
performs any operations on the data given to it, has been deprecated and will be
removed in Pillow 10.0.0 (2023-07-01).
2021-06-30 14:47:41 +03:00
2021-07-29 09:19:53 +03:00
ImagePalette size parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 8.4.0
The ``size`` parameter will be removed in Pillow 10.0.0 (2023-07-01).
2021-07-29 09:19:53 +03:00
Before Pillow 8.3.0, ``ImagePalette`` required palette data of particular lengths by
2021-07-29 09:19:53 +03:00
default, and the size parameter could be used to override that. Pillow 8.3.0 removed
the default required length, also removing the need for the size parameter.
2022-01-16 03:38:34 +03:00
ImageShow.Viewer.show_file file argument
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 9.1.0
The ``file`` argument in :py:meth:`~PIL.ImageShow.Viewer.show_file()` has been
deprecated and will be removed in Pillow 10.0.0 (2023-07-01). It has been replaced by
``path``.
2022-01-16 03:38:34 +03:00
In effect, ``viewer.show_file("test.jpg")`` will continue to work unchanged.
``viewer.show_file(file="test.jpg")`` will raise a deprecation warning, and suggest
``viewer.show_file(path="test.jpg")`` instead.
2022-02-18 14:13:11 +03:00
Constants
~~~~~~~~~
.. deprecated:: 9.1.0
2022-02-18 14:13:11 +03:00
A number of constants have been deprecated and will be removed in Pillow 10.0.0
(2023-07-01). Instead, ``enum.IntEnum`` classes have been added.

Removed features
----------------
Deprecated features are only removed in major releases after an appropriate
period of deprecation has passed.
PILLOW_VERSION constant
~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 5.2.0
.. versionremoved:: 9.0.0
Use ``__version__`` instead.
It was initially removed in Pillow 7.0.0, but temporarily brought back in 7.1.0
to give projects more time to upgrade.
2021-10-18 03:08:51 +03:00
Image.show command parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 7.2.0
.. versionremoved:: 9.0.0
The ``command`` parameter has been removed. Use a subclass of
:py:class:`.ImageShow.Viewer` instead.
2021-10-18 02:53:48 +03:00
Image._showxv
~~~~~~~~~~~~~
.. deprecated:: 7.2.0
.. versionremoved:: 9.0.0
Use :py:meth:`.Image.Image.show` instead. If custom behaviour is required, use
:py:func:`.ImageShow.register` to add a custom :py:class:`.ImageShow.Viewer` class.
2021-10-18 02:53:16 +03:00
ImageFile.raise_ioerror
~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 7.2.0
.. versionremoved:: 9.0.0
``IOError`` was merged into ``OSError`` in Python 3.3.
So, ``ImageFile.raise_ioerror`` has been removed.
Use ``ImageFile.raise_oserror`` instead.
FreeType 2.7
~~~~~~~~~~~~
.. deprecated:: 8.1.0
.. versionremoved:: 9.0.0
Support for FreeType 2.7 has been removed.
We recommend upgrading to at least `FreeType`_ 2.10.4, which fixed a severe
vulnerability introduced in FreeType 2.6 (:cve:`CVE-2020-15999`).
.. _FreeType: https://www.freetype.org
im.offset
~~~~~~~~~
.. deprecated:: 1.1.2
.. versionremoved:: 8.0.0
``im.offset()`` has been removed, call :py:func:`.ImageChops.offset()` instead.
It was documented as deprecated in PIL 1.1.2,
raised a ``DeprecationWarning`` since 1.1.5,
an ``Exception`` since Pillow 3.0.0
and ``NotImplementedError`` since 3.3.0.
Image.fromstring, im.fromstring and im.tostring
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 2.0.0
.. versionremoved:: 8.0.0
* ``Image.fromstring()`` has been removed, call :py:func:`.Image.frombytes()` instead.
* ``im.fromstring()`` has been removed, call :py:meth:`~PIL.Image.Image.frombytes()` instead.
* ``im.tostring()`` has been removed, call :py:meth:`~PIL.Image.Image.tobytes()` instead.
They issued a ``DeprecationWarning`` since 2.0.0,
an ``Exception`` since 3.0.0
and ``NotImplementedError`` since 3.3.0.
2019-01-28 15:30:27 +03:00

Python 2.7
~~~~~~~~~~
.. deprecated:: 6.0.0
.. versionremoved:: 7.0.0

Image.__del__
~~~~~~~~~~~~~
.. deprecated:: 6.1.0
.. versionremoved:: 7.0.0
2019-11-01 14:42:12 +03:00
Implicitly closing the image's underlying file in ``Image.__del__`` has been removed.
Use a context manager or call ``Image.close()`` instead to close the file in a
deterministic way.
Previous method:
2019-11-01 14:42:12 +03:00
.. code-block:: python
im = Image.open("hopper.png")
im.save("out.jpg")
Use instead:
.. code-block:: python
with Image.open("hopper.png") as im:
im.save("out.jpg")
PIL.*ImagePlugin.__version__ attributes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 6.0.0
.. versionremoved:: 7.0.0

~~~~~~~~~~~~~~~~
.. deprecated:: 6.0.0
.. versionremoved:: 7.0.0
2019-09-26 21:38:19 +03:00
Qt 4 reached end-of-life on 2015-12-19. Its Python bindings are also EOL: PyQt4 since
2018-08-31 and PySide since 2015-10-14.

or PySide2.
Setting the size of TIFF images
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 5.3.0
.. versionremoved:: 7.0.0
Setting the size of a TIFF image directly (eg. ``im.size = (256, 256)``) throws
an error. Use ``Image.resize`` instead.

~~~~~~~~~~~~~~~~
.. deprecated:: 5.2.0
.. versionremoved:: 6.0.0
``VERSION`` (the old PIL version, always 1.1.7) has been removed. Use
``__version__`` instead.

.. versionremoved:: 6.0.0
2019-01-20 23:07:22 +03:00
Several undocumented functions in ``ImageOps`` have been removed. Use the equivalents
in ``ImageFilter`` instead:
========================== ============================

Removed Use instead
========================== ============================
``ImageOps.box_blur`` ``ImageFilter.BoxBlur``
``ImageOps.gaussian_blur`` ``ImageFilter.GaussianBlur``
``ImageOps.gblur`` ``ImageFilter.GaussianBlur``
``ImageOps.usm`` ``ImageFilter.UnsharpMask``
``ImageOps.unsharp_mask`` ``ImageFilter.UnsharpMask``
========================== ============================
PIL.OleFileIO
~~~~~~~~~~~~~
.. deprecated:: 4.0.0
.. versionremoved:: 6.0.0
PIL.OleFileIO was removed as a vendored file in Pillow 4.0.0 (2017-01) in favour of
2019-01-20 23:07:22 +03:00
the upstream olefile Python package, and replaced with an ``ImportError`` in 5.0.0
(2018-01). The deprecated file has now been removed from Pillow. If needed, install from
2020-03-09 14:39:27 +03:00
PyPI (eg. ``python3 -m pip install olefile``).
