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.
Image.show command parameter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 7.2.0
The ``command`` parameter was deprecated and will be removed in a future release.
Use a subclass of ``ImageShow.Viewer`` instead.
Image._showxv
~~~~~~~~~~~~~
.. deprecated:: 7.2.0
``Image._showxv`` has been deprecated. Use :py:meth:`~PIL.Image.Image.show`
instead. If custom behaviour is required, use :py:meth:`~PIL.ImageShow.register` to add
a custom :py:class:`~PIL.ImageShow.Viewer` class.
ImageFile.raise_ioerror
~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 7.2.0
``IOError`` was merged into ``OSError`` in Python 3.3. So, ``ImageFile.raise_ioerror``
is now deprecated and will be removed in a future release. Use
``ImageFile.raise_oserror`` instead.
PILLOW_VERSION constant
~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 5.2.0
``PILLOW_VERSION`` has been deprecated and will be removed in a future release. Use
``__version__`` instead.
It was initially removed in Pillow 7.0.0, but brought back in 7.1.0 to give projects
more time to upgrade.
Removed features
----------------
Deprecated features are only removed in major releases after an appropriate
period of deprecation has passed.
ImageCms.CmsProfile attributes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 3.2.0
.. versionremoved:: 8.0.0
Some attributes in ``ImageCms.CmsProfile`` have been removed. From 6.0.0, they issued a
``DeprecationWarning``:
======================== ===============================
Removed Use instead
======================== ===============================
``color_space`` Padded ``xcolor_space``
``pcs`` Padded ``connection_space``
``product_copyright`` Unicode ``copyright``
``product_desc`` Unicode ``profile_description``
``product_description`` Unicode ``profile_description``
``product_manufacturer`` Unicode ``manufacturer``
``product_model`` Unicode ``model``
======================== ===============================
Python 2.7
~~~~~~~~~~
.. deprecated:: 6.0.0
.. versionremoved:: 7.0.0
Python 2.7 reached end-of-life on 2020-01-01. Pillow 6.x was the last series to
support Python 2.
Image.__del__
~~~~~~~~~~~~~
.. deprecated:: 6.1.0
.. versionremoved:: 7.0.0
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:
.. 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
The version constants of individual plugins have been removed. Use ``PIL.__version__``
instead.
=============================== ================================= ==================================
Removed Removed Removed
=============================== ================================= ==================================
``BmpImagePlugin.__version__`` ``Jpeg2KImagePlugin.__version__`` ``PngImagePlugin.__version__``
``CurImagePlugin.__version__`` ``JpegImagePlugin.__version__`` ``PpmImagePlugin.__version__``
``DcxImagePlugin.__version__`` ``McIdasImagePlugin.__version__`` ``PsdImagePlugin.__version__``

``ImtImagePlugin.__version__`` ``PdfImagePlugin.__version__`` ``XVThumbImagePlugin.__version__``
``IptcImagePlugin.__version__`` ``PixarImagePlugin.__version__``
=============================== ================================= ==================================
PyQt4 and PySide
~~~~~~~~~~~~~~~~
.. deprecated:: 6.0.0
.. versionremoved:: 7.0.0
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.
Support for PyQt4 and PySide has been removed from ``ImageQt``. Please upgrade to PyQt5
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.
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.
Undocumented ImageOps functions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. deprecated:: 4.3.0
.. versionremoved:: 6.0.0
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 and 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``).
