Backwards Incompatible Changes

Python 3.6

Pillow has dropped support for Python 3.6, which reached end-of-life on 2021-12-23.

PILLOW_VERSION constant

PILLOW_VERSION has been removed. Use __version__ instead.

FreeType 2.7

Support for FreeType 2.7 has been removed; FreeType 2.8 is the minimum supported.

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

Image.show command parameter

The command parameter has been removed. Use a subclass of :pyPIL.ImageShow.Viewer instead.

Image._showxv

Image._showxv has been removed. Use :py~PIL.Image.Image.show instead. If custom behaviour is required, use :py~PIL.ImageShow.register to add a custom :py~PIL.ImageShow.Viewer class.

ImageFile.raise_ioerror

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

API Changes

API Additions

Added support for "title" argument to DisplayViewer

Support has been added for the "title" argument in :py~PIL.ImageShow.UnixViewer.DisplayViewer, so that when im.show() or :py.ImageShow.show() use the display command line tool, the "title" argument will also now be supported, e.g. im.show(title="My Image") and ImageShow.show(im, title="My Image").

Other Changes

Convert subsequent GIF frames to RGB or RGBA

Since each frame of a GIF can have up to 256 colors, after the first frame it is possible for there to be too many colors to fit in a P mode image. To allow for this, seeking to any subsequent GIF frame will now convert the image to RGB or RGBA, depending on whether or not the first frame had transparency.

Added support for pickling TrueType fonts

TrueType fonts may now be pickled and unpickled. For example:

import pickle
from PIL import ImageFont

font = ImageFont.truetype("arial.ttf", size=30)
pickled_font = pickle.dumps(font, protocol=pickle.HIGHEST_PROTOCOL)

# Later...
unpickled_font = pickle.loads(pickled_font)

Added support for additional TGA orientations

TGA images with top right or bottom right orientations are now supported.
