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.

ImageFile.raise_oserror#

Deprecated since version 10.2.0.

ImageFile.raise_oserror() has been deprecated and will be removed in Pillow 12.0.0 (2025-10-15). The function is undocumented and is only useful for translating error codes returned by a codec’s decode() method, which ImageFile already does automatically.

IptcImageFile helper functions#

Deprecated since version 10.2.0.

The functions IptcImageFile.dump and IptcImageFile.i, and the constant IptcImageFile.PAD have been deprecated and will be removed in Pillow 12.0.0 (2025-10-15). These are undocumented helper functions intended for internal use, so there is no replacement. They can each be replaced by a single line of code using builtin functions in Python.

ImageCms constants and versions() function#

Deprecated since version 10.3.0.

A number of constants and a function in ImageCms have been deprecated. This includes a table of flags based on LittleCMS version 1 which has been replaced with a new class ImageCms.Flags based on LittleCMS 2 flags.

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.

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. See Constants

Several functions for computing the size and offset of rendered text have been removed:

Removed

Use instead

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 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.

IOError was merged into OSError in Python 3.3. So, ImageFile.raise_ioerror has been removed. Use ImageFile.raise_oserror instead.

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.

Previous method:

im = Image.open("hopper.png")
im.save("out.jpg")

Use instead:

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

PIL.*ImagePlugin.__version__ attributes#

Deprecated since version 6.0.0.

Setting the size of TIFF images#

Deprecated since version 5.3.0.

Removed in version 7.0.0.

Setting the size of a TIFF image directly (eg. im.size = (256, 256)) throws an error. Use Image.resize instead.

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 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).

import _imaging#

Removed in version 2.1.0.

Pillow >= 2.1.0 no longer supports import _imaging. Please use from PIL.Image import core as _imaging instead.

Removed in version 1.0.0.

Pillow and PIL cannot co-exist in the same environment. Before installing Pillow, please uninstall PIL.

import Image#

Removed in version 1.0.0.

Pillow >= 1.0 no longer supports import Image. Please use from PIL import Image instead.
