Backwards Incompatible Changes
|
|
==============================
|
|
|
|
Python 3.4 dropped
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
Python 3.4 is EOL since 2019-03-16 and no longer supported. We will not be creating
|
|
binaries, testing, or retaining compatibility with this version. The final version of
|
|
Pillow for Python 3.4 is 5.4.1.
|
|
|
|
Removed deprecated PIL.OleFileIO
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``PIL.OleFileIO`` was removed as a vendored file and in Pillow 4.0.0 (2017-01) in favour of
|
|
the upstream :pypi:`olefile` Python package, and replaced with an :py:exc:`ImportError`. The
|
|
deprecated file has now been removed from Pillow. If needed, install from PyPI (eg.
|
|
``python3 -m pip install olefile``).
|
|
|
|
Removed deprecated ImageOps functions
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Several undocumented functions in ``ImageOps`` were deprecated in Pillow 4.3.0 (2017-10)
|
|
and have now been removed: ``gaussian_blur``, ``gblur``, ``unsharp_mask``, ``usm`` and
|
|
``box_blur``. Use the equivalent operations in ``ImageFilter`` instead.
|
|
|
|
Removed deprecated VERSION
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``VERSION`` (the old PIL version, always 1.1.7) has been removed. Use ``__version__``
|
|
instead.
|
|
|

Deprecations
|
|
^^^^^^^^^^^^
|
|
|
|
Python 2.7
|
|
~~~~~~~~~~
|
|
|
|
Python 2.7 reaches end-of-life on 2020-01-01.
|
|
|
|
Pillow 7.0.0 will be released on 2020-01-01 and will drop support for Python 2.7, making
|
|
Pillow 6.x the last series to support Python 2.
|
|
|
|
PyQt4 and PySide
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
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.
|
|
|
|

|
ImageCms.CmsProfile attributes
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Some attributes in ``ImageCms.CmsProfile`` have been deprecated since Pillow 3.2.0. From
|
|
6.0.0, they issue a :py:exc:`DeprecationWarning`:
|
|
|
|
======================== ===============================
|
|
Deprecated 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``
|
|
======================== ===============================
|
|
|
|
MIME type improvements
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Previously, all JPEG2000 images had the MIME type "image/jpx". This has now been
|
|
corrected. After the file format drivers have been loaded, ``Image.MIME["JPEG2000"]``
|
|
will return "image/jp2". ``ImageFile.get_format_mimetype`` will return "image/jpx" if
|
|
a JPX profile is present, or "image/jp2" otherwise.
|
|
|
|
Previously, all SGI images had the MIME type "image/rgb". This has now been
|
|
corrected. After the file format drivers have been loaded, ``Image.MIME["SGI"]``
|
|
will return "image/sgi". ``ImageFile.get_format_mimetype`` will return "image/rgb" if
|
|
RGB image data is present, or "image/sgi" otherwise.
|
|
|
|
MIME types have been added to the PPM format. After the file format drivers have been
|
|
loaded, ``Image.MIME["PPM"]`` will now return the generic "image/x-portable-anymap".
|
|
``ImageFile.get_format_mimetype`` will return a MIME type specific to the color type.
|
|
|
|
The TGA, PCX and ICO formats also now have MIME types: "image/x-tga", "image/x-pcx" and
|
|
"image/x-icon" respectively.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
DIB file format
|
|
^^^^^^^^^^^^^^^
|
|
|
|
Pillow now supports reading and writing the Device Independent Bitmap file format.
|
|
|
|
Image.quantize
|
|
^^^^^^^^^^^^^^
|
|
|
|
The ``dither`` option is now a customisable parameter (was previously hardcoded to ``1``).
|
|
This parameter takes the same values used in :py:meth:`~PIL.Image.Image.convert`.
|
|
|
|
New language parameter
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
These text-rendering functions now accept a ``language`` parameter to request
|
|
language-specific glyphs and ligatures from the font:
|
|
|
|
* ``ImageDraw.ImageDraw.multiline_text()``
|
|
* ``ImageDraw.ImageDraw.multiline_textsize()``
|
|
* ``ImageDraw.ImageDraw.text()``
|
|
* ``ImageDraw.ImageDraw.textsize()``
|
|
* ``ImageFont.ImageFont.getmask()``
|
|
* ``ImageFont.ImageFont.getsize_multiline()``
|
|
* ``ImageFont.ImageFont.getsize()``
|
|
|
|
Added EXIF class
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
:py:meth:`~PIL.Image.Image.getexif` has been added, which returns an
|
|
:py:class:`~PIL.Image.Exif` instance. Values can be retrieved and set like a
|
|
dictionary. When saving JPEG, PNG or WEBP, the instance can be passed as an
|
|
``exif`` argument to include any changes in the output image.
|
|
|
|
Added ImageOps.exif_transpose
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:meth:`~PIL.ImageOps.exif_transpose` returns a copy of an image, transposed
|
|
according to its EXIF Orientation tag.
|
|
|
|
PNG EXIF data
|
|
^^^^^^^^^^^^^
|
|
|
|
EXIF data can now be read from and saved to PNG images. However, unlike other image
|
|
formats, EXIF data is not guaranteed to be present in :py:attr:`~PIL.Image.Image.info`
|
|
until :py:meth:`~PIL.Image.Image.load` has been called.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
Reading new DDS image format
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Pillow can now read uncompressed RGB data from DDS images.
|
|
|
|
Reading TIFF with old-style JPEG compression
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Added support reading TIFF files with old-style JPEG compression through LibTIFF. All
|
|
YCbCr TIFF images are now always read as RGB.
|
|
|
|
TIFF compression codecs
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Support has been added for the LZMA, Zstd and WebP TIFF compression codecs.
|
|
|
|
Improved support for transposing I;16 images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
I;16, I;16L and I;16B are now supported image modes for all
|
|
:py:meth:`~PIL.Image.Image.transpose` operations.
|
