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 since version 9.5.0.
The 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.
PyAccess and Image.USE_CFFI_ACCESS#
Deprecated since version 10.0.0.
Since Pillow’s C API is now faster than PyAccess on PyPy,
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.
Removed features#
Deprecated features are only removed in major releases after an appropriate period of deprecation has passed.
Tk/Tcl 8.4#
Deprecated since version 8.2.0.
Removed in version 10.0.0.
Support for Tk/Tcl 8.4 was removed in Pillow 10.0.0 (2023-07-01).
Categories#
Deprecated since version 8.2.0.
Removed in version 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 since version 8.3.0.
Removed in version 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 since version 8.4.0.
Removed in version 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 since version 9.1.0.
Removed in version 10.0.0.
The file
argument in show_file()
has been
removed and replaced by path
.
In effect, viewer.show_file("test.jpg")
will continue to work unchanged.
Constants#
Deprecated since version 9.1.0.
Removed in version 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.

Previous code:

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 since version 9.2.0.
Removed in version 10.0.0.

. Upgrade to
PyQt6 or
PySide6 instead.

Removed in version 10.0.0.
This undocumented method has been removed.
PILLOW_VERSION constant#
Deprecated since version 5.2.0.

Removed in version 9.0.0.
The command
parameter has been removed. Use a subclass of
ImageShow.Viewer
instead.
Image._showxv#
Deprecated since version 7.2.0.
Removed in version 9.0.0.

instead. If custom behaviour is required, use
ImageShow.register()
to add a custom ImageShow.Viewer
class.
ImageFile.raise_ioerror#
Deprecated since version 7.2.0.
Removed in version 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 since version 8.1.0.
Removed in version 9.0.0.

Image.__del__#
Deprecated since version 6.1.0.
Removed in version 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.

im = Image.open("hopper.png")
im.save("out.jpg")
Use instead:
with Image.open("hopper.png") as im:
im.save("out.jpg")

Setting the size of TIFF images#
Deprecated since version 5.3.0.

PIL.OleFileIO#
Deprecated since version 4.0.0.
Removed in version 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
