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.

Tk/Tcl 8.4

Deprecated since version 8.2.0.

Support for Tk/Tcl 8.4 is deprecated and will be removed in Pillow 10.0.0 (2023-07-01), when Tk/Tcl 8.5 will be the minimum supported.

Categories

Deprecated since version 8.2.0.

im.category is deprecated and will be removed in Pillow 10.0.0 (2023-07-01), 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.

JPEG quantization is now automatically converted, but still returned as a dictionary. The convert_dict_qtables method no longer performs any operations on the data given to it, has been deprecated and will be removed in Pillow 10.0.0 (2023-07-01).

ImagePalette size parameter

Deprecated since version 8.4.0.

The size parameter will be removed in Pillow 10.0.0 (2023-07-01).

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.

The file argument in show_file() has been deprecated and will be removed in Pillow 10.0.0 (2023-07-01). It has been replaced by path.

In effect, viewer.show_file("test.jpg") will continue to work unchanged. viewer.show_file(file="test.jpg") will raise a deprecation warning, and suggest viewer.show_file(path="test.jpg") instead.

Constants

Deprecated since version 9.2.0.

A number of constants have been deprecated and will be removed in Pillow 10.0.0 (2023-07-01). Instead, enum.IntEnum classes have been added.

Removed features

Deprecated features are only removed in major releases after an appropriate period of deprecation has passed.

PILLOW_VERSION constant

Deprecated since version 5.2.0.

Removed in version 9.0.0.

Use __version__ instead.

It was initially removed in Pillow 7.0.0, but temporarily brought back in 7.1.0 to give projects more time to upgrade.

Image.show command parameter

Deprecated since version 7.2.0.

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.

Use Image.Image.show() 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.

Support for FreeType 2.7 has been removed.

We recommend upgrading to at least FreeType 2.10.4, which fixed a severe vulnerability introduced in FreeType 2.6 (CVE-2020-15999).

im.offset

Deprecated since version 1.1.2.

Removed in version 8.0.0.

im.offset() has been removed, call ImageChops.offset() instead.

It was documented as deprecated in PIL 1.1.2, raised a DeprecationWarning since 1.1.5, an Exception since Pillow 3.0.0 and NotImplementedError since 3.3.0.

Image.fromstring, im.fromstring and im.tostring

Deprecated since version 2.0.0.

Removed in version 8.0.0.

  • Image.fromstring() has been removed, call Image.frombytes() instead.

  • im.fromstring() has been removed, call frombytes() instead.

  • im.tostring() has been removed, call tobytes() instead.

They issued a DeprecationWarning since 2.0.0, an Exception since 3.0.0 and NotImplementedError since 3.3.0.

ImageCms.CmsProfile attributes

Deprecated since version 3.2.0.

Removed in version 8.0.0.

Some attributes in PIL.ImageCms.CmsProfile have been removed. From 6.0.0, they issued a DeprecationWarning:

Python 2.7

Deprecated since version 6.0.0.

Removed in version 7.0.0.

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.

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.

Removed in version 7.0.0.
