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.
|
||
|
||
PyQt4 and PySide
|
||
~~~~~~~~~~~~~~~~
|
||
|
||
.. deprecated:: 6.0.0
|
||
|
||
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 deprecated from ``ImageQt`` and will be removed in
|
||
a future version. Please upgrade to PyQt5 or PySide2.
|
||
|
||
PIL.*ImagePlugin.__version__ attributes
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
.. deprecated:: 6.0.0
|
||
|
||
The version constants of individual plugins have been deprecated and will be removed in
|
||
a future version. Use ``PIL.__version__`` instead.

Setting the size of TIFF images
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
.. deprecated:: 5.3.0
|
||
|
||
Setting the image size of a TIFF image (eg. ``im.size = (256, 256)``) issues
|
||
a ``DeprecationWarning``:
|
||
|
||
.. code-block:: none
|
||
|
||
Setting the size of a TIFF image directly is deprecated, and will
|
||
be removed in a future version. Use the resize method instead.
|
||
|
||
PILLOW_VERSION and VERSION constants
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
.. deprecated:: 5.2.0
|
||
|
||
Two version constants – ``VERSION`` (the old PIL version, always 1.1.7) and
|
||
``PILLOW_VERSION`` – have been deprecated and will be removed in the next
|
||
major release. Use ``__version__`` instead.
|
||
|
||
Removed features
|
||
----------------
|
||
|
||
Deprecated features are only removed in major releases after an appropriate
|
||
period of deprecation has passed.
|
||
|
||
Undocumented ImageOps functions
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
*Removed in version 6.0.0.*
|
||
|
||
Several undocumented functions in ``ImageOps`` have been removed. Use the equivalents
|
||
in ``ImageFilter`` instead:

PIL.OleFileIO
|
||
~~~~~~~~~~~~~
|
||
|
||
*Removed in version 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. ``pip install olefile``).
