This release is dedicated to the memory of Fredrik Lundh, aka Effbot, who died in November 2021. Fredrik created PIL in 1995 and he was instrumental in the early success of Python.
Fredrik was an early Python contributor (e.g. Elementtree and the 're' module) and his enthusiasm for the language and community were inspiring for all who encountered him or his work. He spent countless hours on comp.lang.python answering questions from newbies and advanced users alike.
He also co-founded an early Python startup, Secret Labs AB, which among other software released an IDE named PythonWorks. Fredrik also created the Python Imaging Library (PIL) which is still THE way to interact with images in Python, now most often through its Pillow fork. His effbot.org site was a valuable resource for generations of Python users, especially its Tkinter documentation.
Thank you, Fredrik.
Pillow has dropped support for Python 3.6, which reached end-of-life on 2021-12-23.
PILLOW_VERSION
has been removed. Use __version__
instead.
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
).
The command
parameter has been removed. Use a subclass of :pyPIL.ImageShow.Viewer
instead.
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.
IOError
was merged into OSError
in Python 3.3. So, ImageFile.raise_ioerror
has been removed. Use ImageFile.raise_oserror
instead.
An optional line width
parameter has been added to ImageDraw.Draw.polygon
.
If xdg-open
is present on Linux, this new :pyPIL.ImageShow.Viewer
subclass will be registered. It displays images using the application selected by the system.
It is higher in priority than the other default :pyPIL.ImageShow.Viewer
instances, so it will be preferred by im.show()
or :py.ImageShow.show()
.
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")
.
JpegImagePlugin
may append an EOF marker to the end of a truncated file, so that the last segment of the data will still be processed by the decoder.
If the EOF marker is not detected as such however, this could lead to an infinite loop where JpegImagePlugin
keeps trying to end the file.
To prevent attempts to slow down loading times for images, if an image has consecutive duplicate tiles that only differ by their offset, only load the last tile. Credit to Google's OSS-Fuzz project for finding this issue.
CWE-126 and CWE-665 were found when initializing ImagePath.Path
.
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.
The Pillow wheels from PyPI for macOS and Linux have switched from libjpeg to libjpeg-turbo. It is a fork of libjpeg, popular for its speed.
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)
TGA images with top right or bottom right orientations are now supported.
