11.2.1 (2025-04-12)¶
Warning
The release of Pillow 11.2.0 was halted prematurely, due to hitting PyPI’s project size limit and concern over the size of Pillow wheels containing libavif. The PyPI limit has now been increased and Pillow 11.2.1 has been released instead, without libavif included in the wheels. To avoid confusion, the incomplete 11.2.0 release has been removed from PyPI.
Security¶
Undefined shift when loading compressed DDS images¶
When loading some compressed DDS formats, an integer was bitshifted by 24 places to generate the 32 bits of the lookup table. This was undefined behaviour, and has been present since Pillow 3.4.0.
Deprecations¶
Image.Image.get_child_images()¶
Deprecated since version 11.2.1.
Image.Image.get_child_images()
has been deprecated. and will be removed in Pillow
13 (2026-10-15). It will be moved to ImageFile.ImageFile.get_child_images()
. The
method uses an image’s file pointer, and so child images could only be retrieved from
an PIL.ImageFile.ImageFile
instance.
API Changes¶
append_images
no longer requires save_all
¶
Previously, save_all
was required to in order to use append_images
. Now,
save_all
will default to True
if append_images
is not empty and the format
supports saving multiple frames:
im.save("out.gif", append_images=ims)
API Additions¶
"justify"
multiline text alignment¶
In addition to "left"
, "center"
and "right"
, multiline text can also be
aligned using "justify"
in ImageDraw
:
from PIL import Image, ImageDraw
im = Image.new("RGB", (50, 25))
draw = ImageDraw.Draw(im)
draw.multiline_text((0, 0), "Multiline\ntext 1", align="justify")
draw.multiline_textbbox((0, 0), "Multiline\ntext 2", align="justify")
Specify window in ImageGrab on Windows¶
When using grab()
, a specific window can be selected using the
HWND:
from PIL import ImageGrab
ImageGrab.grab(window=hwnd)
Check for MozJPEG¶
You can check if Pillow has been built against the MozJPEG version of the libjpeg library, and what version of MozJPEG is being used:
from PIL import features
features.check_feature("mozjpeg") # True or False
features.version_feature("mozjpeg") # "4.1.1" for example, or None
Saving compressed DDS images¶
Compressed DDS images can now be saved using a pixel_format
argument. DXT1, DXT3,
DXT5, BC2, BC3 and BC5 are supported:
im.save("out.dds", pixel_format="DXT1")
Other Changes¶
Arrow support¶
Arrow is an in-memory data exchange format that is the
spiritual successor to the NumPy array interface. It provides for zero-copy access to
columnar data, which in our case is Image
data.
To create an image with zero-copy shared memory from an object exporting the arrow_c_array interface protocol:
from PIL import Image
import pyarrow as pa
arr = pa.array([0]*(5*5*4), type=pa.uint8())
im = Image.fromarrow(arr, 'RGBA', (5, 5))
Pillow images can also be converted to Arrow objects:
from PIL import Image
import pyarrow as pa
im = Image.open('hopper.jpg')
arr = pa.array(im)
Reading and writing AVIF images¶
Pillow can now read and write AVIF images when built from source with libavif 1.0.0 or later.
