|
|
|
Limit size even if one dimension is zero
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
When performing decompression bomb checks, Pillow did not reject images with
|
|
excessive width and zero height, or zero width and excessive height. That has
|
|
now been fixed.
|
|
|
|
This effectively dates to the PIL fork, since problem images would still have
|
|
been processed before Pillow started checking for decompression bombs.
|
|
|
|
.. _Added ImageFont.MAX_STRING_LENGTH:
|
|
|
|
:cve:`2023-44271`: Added ImageFont.MAX_STRING_LENGTH
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
To protect against potential DOS attacks when using arbitrary strings as text
|
|
input, Pillow will now raise a :py:exc:`ValueError` if the number of characters
|
|
passed into ImageFont methods is over a certain limit,
|
|
:py:data:`PIL.ImageFont.MAX_STRING_LENGTH`.
|
|
|
|
This threshold can be changed by setting
|
|
:py:data:`PIL.ImageFont.MAX_STRING_LENGTH`. It can be disabled by setting
|
|
``ImageFont.MAX_STRING_LENGTH = None``.
|
|
|
|
Backwards Incompatible Changes
|
|
==============================
|
|
|
|
Categories
|
|
^^^^^^^^^^
|
|
|
|
``im.category`` has been 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.
|
|
|
|
Tk/Tcl 8.4
|
|
^^^^^^^^^^
|
|
|
|
Support for Tk/Tcl 8.4 has been removed.
|
|
|
|
JpegImagePlugin.convert_dict_qtables
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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
|
|
^^^^^^^^^
|
|
|
|
A number of constants have been removed.
|
|
Instead, :py:class:`enum.IntEnum` classes have been added.
|
|
|
|

FitsStubImagePlugin
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
The stub image plugin ``FitsStubImagePlugin`` has been removed.
|
|
FITS images can be read without a handler through :mod:`~PIL.FitsImagePlugin` instead.
|
|
|
|
Font size and offset methods
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
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`
|
|
=============================================================== =============================================================================================================
|
|
|
|
FreeTypeFont.getmask2 fill parameter
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The undocumented ``fill`` parameter of :py:meth:`.FreeTypeFont.getmask2` has been
|
|
removed.
|
|
|
|
PhotoImage.paste box parameter
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The ``box`` parameter was unused and has been removed.
|
|
|
|
PyQt5 and PySide2
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
`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
|
|
^^^^^^^^^^^^^^
|
|
|
|
This undocumented method has been removed.
|
|
|
|
Deprecations
|
|
============
|
|
|
|
PyAccess and Image.USE_CFFI_ACCESS
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Since Pillow's C API is now faster than PyAccess on PyPy,
|
|
:py:mod:`!PyAccess` has been deprecated and will be removed in Pillow
|
|
11.0.0 (2024-10-15). Pillow's C API will now be used by default on PyPy instead.
|
|
|
|
``Image.USE_CFFI_ACCESS``, for switching from the C API to PyAccess, is
|
|
similarly deprecated.
|
|
|
|
API Changes
|
|
===========
|
|
|
|
Added line width parameter to ImageDraw regular_polygon
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
An optional line ``width`` parameter has been added to
|
|
``ImageDraw.Draw.regular_polygon``.
|
|
|
|
API Additions
|
|
=============
|
|
|
|
Added ``alpha_only`` argument to ``getbbox()``
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
:py:meth:`~PIL.Image.Image.getbbox` now accepts a keyword argument of
|
|
``alpha_only``. This is an optional flag, defaulting to ``True``. If ``True``
|
|
and the image has an alpha channel, trim transparent pixels. Otherwise, trim
|
|
pixels when all channels are zero.
|
|
|
|
Other Changes
|
|
=============
|
|
|
|
32-bit wheels
|
|
^^^^^^^^^^^^^
|
|
|
|
32-bit wheels are no longer provided.
|
|
|
|
Support display_jpeg() in IPython
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
In addition to ``display()`` and ``display_png``, ``display_jpeg()`` can now
|
|
also be used to display images in IPython::
|
|
|
|
from PIL import Image
|
|
from IPython.display import display_jpeg
|
|
|
|
im = Image.new("RGB", (100, 100), (255, 0, 0))
|
|
display_jpeg(im)
|
|
|
|
Support reading signed 8-bit TIFF images
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
TIFF images with signed integer data, 8 bits per sample and a photometric
|
|
interpretation of BlackIsZero can now be read.
|
