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.
PSFile
~~~~~~
.. deprecated:: 9.5.0
The :py:class:`~PIL.EpsImagePlugin.PSFile` class has been deprecated and will
be removed in Pillow 11 (2024-10-15). This class was only made as a helper to
be used internally, so there is no replacement. If you need this functionality
though, it is a very short class that can easily be recreated in your own code.
Removed features
----------------
Deprecated features are only removed in major releases after an appropriate
period of deprecation has passed.
Tk/Tcl 8.4
~~~~~~~~~~
.. deprecated:: 8.2.0
.. versionremoved:: 10.0.0
Support for Tk/Tcl 8.4 was removed in Pillow 10.0.0 (2023-07-01).
Categories
~~~~~~~~~~
.. deprecated:: 8.2.0
.. versionremoved:: 10.0.0
``im.category`` was removed 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.
JpegImagePlugin.convert_dict_qtables
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 8.3.0
.. versionremoved:: 10.0.0
Since deprecation in Pillow 8.3.0, the ``convert_dict_qtables`` method no longer
performed any operations on the data given to it, and has been removed.
ImagePalette size parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 8.4.0
.. versionremoved:: 10.0.0
Before Pillow 8.3.0, ``ImagePalette`` required palette data of particular lengths by
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.
ImageShow.Viewer.show_file file argument
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 9.1.0
.. versionremoved:: 10.0.0
The ``file`` argument in :py:meth:`~PIL.ImageShow.Viewer.show_file()` has been
removed and replaced by ``path``.
In effect, ``viewer.show_file("test.jpg")`` will continue to work unchanged.
Constants
~~~~~~~~~
.. deprecated:: 9.1.0
.. versionremoved:: 10.0.0
A number of constants have been removed.
Instead, ``enum.IntEnum`` classes have been added.
.. note::
Additional ``Image`` constants were deprecated in Pillow 9.1.0, but that
was reversed in Pillow 9.4.0 and those constants will now remain available.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 9.2.0
.. versionremoved:: 10.0.0
Several functions for computing the size and offset of rendered text have been removed:
=============================================================== =============================================================================================================
Removed Use instead
=============================================================== =============================================================================================================
``FreeTypeFont.getsize()`` and ``FreeTypeFont.getoffset()`` :py:meth:`.FreeTypeFont.getbbox` and :py:meth:`.FreeTypeFont.getlength`
``FreeTypeFont.getsize_multiline()`` :py:meth:`.ImageDraw.multiline_textbbox`

``ImageDraw2.Draw.textsize()`` :py:meth:`.ImageDraw2.Draw.textbbox` and :py:meth:`.ImageDraw2.Draw.textlength`
=============================================================== =============================================================================================================
Previous code::
from PIL import Image, ImageDraw, ImageFont
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")
width, height = font.getsize("Hello world")
left, top = font.getoffset("Hello world")
im = Image.new("RGB", (100, 100))
draw = ImageDraw.Draw(im)
width, height = draw.textsize("Hello world")
width, height = font.getsize_multiline("Hello\nworld")
width, height = draw.multiline_textsize("Hello\nworld")
Use instead::
from PIL import Image, ImageDraw, ImageFont
font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")
left, top, right, bottom = font.getbbox("Hello world")
width, height = right - left, bottom - top
im = Image.new("RGB", (100, 100))
draw = ImageDraw.Draw(im)
width = draw.textlength("Hello world")
left, top, right, bottom = draw.multiline_textbbox((0, 0), "Hello\nworld")
width, height = right - left, bottom - top
FreeTypeFont.getmask2 fill parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 9.2.0
.. versionremoved:: 10.0.0
The undocumented ``fill`` parameter of :py:meth:`.FreeTypeFont.getmask2` has been
removed.
PhotoImage.paste box parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 9.2.0
.. versionremoved:: 10.0.0
The ``box`` parameter was unused and has been removed.
PyQt5 and PySide2
~~~~~~~~~~~~~~~~~
.. deprecated:: 9.2.0
.. versionremoved:: 10.0.0
`Qt 5 reached end-of-life <https://www.qt.io/blog/qt-5.15-released>`_ on 2020-12-08 for
open-source users (and will reach EOL on 2023-12-08 for commercial licence holders).
Support for PyQt5 and PySide2 has been removed from ``ImageQt``. Upgrade to
`PyQt6 <https://www.riverbankcomputing.com/static/Docs/PyQt6/>`_ or
`PySide6 <https://doc.qt.io/qtforpython-6/>`_ instead.
Image.coerce_e
~~~~~~~~~~~~~~
.. deprecated:: 9.2.0
.. versionremoved:: 10.0.0
This undocumented method has been removed.
PILLOW_VERSION constant
~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 5.2.0
.. versionremoved:: 9.0.0

It was initially removed in Pillow 7.0.0, but temporarily brought back in 7.1.0
to give projects more time to upgrade.
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.

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

.. _FreeType: https://freetype.org/
im.offset
~~~~~~~~~
.. deprecated:: 1.1.2
.. versionremoved:: 8.0.0

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.

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

Several undocumented functions in ``ImageOps`` have been removed. Use the equivalents
in ``ImageFilter`` instead:

========================== ============================
``ImageOps.box_blur`` ``ImageFilter.BoxBlur``
``ImageOps.gaussian_blur`` ``ImageFilter.GaussianBlur``
``ImageOps.gblur`` ``ImageFilter.GaussianBlur``

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
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
PyPI (eg. ``python3 -m pip install olefile``).
