**Deprecations#**

**Categories#**

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.

**Tk/Tcl 8.4#**

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.

**API Changes#**

**Image.alpha\_composite: dest#**

When calling alpha_composite(), the dest argument now accepts negative co-ordinates, like the upper left corner of the box argument of paste() can be negative. Naturally, this has effect of cropping the overlaid image.

**Image.getexif: EXIF and GPS IFD#**

Previously, getexif() flattened the EXIF IFD into the rest of the data, losing information. This information is now kept separate, moved under im.getexif().get_ifd(0x8769).

Direct access to the GPS IFD dictionary was possible through im.getexif()[0x8825]. This is now consistent with other IFDs, and must be accessed through im.getexif().get_ifd(0x8825).

These changes only affect getexif(), introduced in Pillow 6.0. The older _getexif() methods are unaffected.

**Image.\_MODEINFO#**

This internal dictionary had been deprecated by a comment since PIL, and is now removed. Instead, Image.getmodebase(), Image.getmodetype(), Image.getmodebandnames(), Image.getmodebands() or ImageMode.getmode() can be used.

**API Additions#**

**getxmp() for JPEG images#**

A new method has been added to return XMP data for JPEG images. It reads the XML data into a dictionary of names and values.

For example:

\>>> from PIL import Image
\>>> with Image.open("Tests/images/xmp\_test.jpg") as im:
\>>>     print(im.getxmp())
{'RDF': {}, 'Description': {'Version': '10.4', 'ProcessVersion': '10.0', ...}, ...}

**ImageDraw.rounded\_rectangle#**

Added rounded_rectangle(). It works the same as rectangle(), except with an additional radius argument. radius is limited to half of the width or the height, so that users can create a circle, but not any other ellipse.

from PIL import Image, ImageDraw
im \= Image.new("RGB", (200, 200))
draw \= ImageDraw.Draw(im)
draw.rounded\_rectangle(xy\=(10, 20, 190, 180), radius\=30, fill\="red")

**ImageOps.autocontrast: preserve\_tone#**

The default behaviour of autocontrast() is to normalize separate histograms for each color channel, changing the tone of the image. The new preserve_tone argument keeps the tone unchanged by using one luminance histogram for all channels.

**ImageShow.GmDisplayViewer#**

If GraphicsMagick is present, this new PIL.ImageShow.Viewer subclass will be registered. It uses GraphicsMagick, an ImageMagick fork, to display images.

The GraphicsMagick based viewer has a lower priority than its ImageMagick counterpart. Thus, if both ImageMagick and GraphicsMagick are installed, im.show() and ImageShow.show() prefer the viewer based on ImageMagick, i.e the behaviour stays the same for Pillow users having ImageMagick installed.

**ImageShow.IPythonViewer#**

If IPython is present, this new PIL.ImageShow.Viewer subclass will be registered. It displays images on all IPython frontends. This will be helpful to users of Google Colab, allowing im.show() to display images.

It is lower in priority than the other default PIL.ImageShow.Viewer instances, so it will only be used by im.show() or ImageShow.show() if none of the other viewers are available. This means that the behaviour of PIL.ImageShow will stay the same for most Pillow users.

**Saving TIFF with ICC profile#**

As is already possible for JPEG, PNG and WebP, the ICC profile for TIFF files can now be specified through a keyword argument:

im.save("out.tif", icc\_profile\=...)

**Security#**

These were all found with OSS-Fuzz.

**CVE-2021-25287, CVE-2021-25288: Fix OOB read in Jpeg2KDecode#**

*   For J2k images with multiple bands, it’s legal to have different widths for each band, e.g. 1 byte for L, 4 bytes for A.
    
*   This dates to Pillow 2.4.0.
    

**CVE-2021-28675: Fix DOS in PsdImagePlugin#**

*   PsdImagePlugin.PsdImageFile did not sanity check the number of input layers with regard to the size of the data block, this could lead to a denial-of-service on open() prior to load().
    
*   This dates to the PIL fork.
    

**CVE-2021-28676: Fix FLI DOS#**

*   FliDecode.c did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load.
    
*   This dates to the PIL fork.
    

**CVE-2021-28677: Fix EPS DOS on \_open#**

*   The readline used in EPS has to deal with any combination of \r and \n as line endings. It accidentally used a quadratic method of accumulating lines while looking for a line ending.
    
*   A malicious EPS file could use this to perform a denial-of-service of Pillow in the open phase, before an image was accepted for opening.
    
*   This dates to the PIL fork.
    

**CVE-2021-28678: Fix BLP DOS#**

*   BlpImagePlugin did not properly check that reads after jumping to file offsets returned data. This could lead to a denial-of-service where the decoder could be run a large number of times on empty data.
    
*   This dates to Pillow 5.1.0.
    

**Fix memory DOS in ImageFont#**

*   A corrupt or specially crafted TTF font could have font metrics that lead to unreasonably large sizes when rendering text in font. ImageFont.py did not check the image size before allocating memory for it.
    
*   This dates to the PIL fork.
    

**Other Changes#**

**GIF writer uses LZW encoding#**

GIF files are now written using LZW encoding, which will generate smaller files, typically about 70% of the size generated by the older encoder.

The pixel data is encoded using the format specified in the CompuServe GIF standard.

The older encoder used a variant of run-length encoding that was compatible but less efficient.

**GraphicsMagick#**

The test suite can now be run on systems which have GraphicsMagick but not ImageMagick installed. If both are installed, the tests prefer ImageMagick.

**Libraqm and FriBiDi linking#**

The way the libraqm dependency for complex text scripts is linked has been changed:

Source builds will now link against the system version of libraqm at build time rather than at runtime by default.

Binary wheels now include a statically linked modified version of libraqm that links against FriBiDi at runtime instead. This change is intended to address issues with the previous implementation on some platforms. These are created by building Pillow with the new build flags --vendor-raqm --vendor-fribidi.

Windows users will now need to install fribidi.dll (or fribidi-0.dll) only, libraqm.dll is no longer used.

See installation documentation for more information.

**PyQt6#**

Support has been added for PyQt6. If it is installed, it will be used instead of PySide6, PyQt5 or PySide2.

CVE-2021-28676: 8.2.0

**Issue**

Istio contains a remotely exploitable vulnerability where an external client can access unexpected services in the cluster, bypassing authorization checks, when a gateway is configured with AUTO_PASSTHROUGH routing configuration.

**Am I impacted?**

This vulnerability impacts only usage of the AUTO_PASSTHROUGH Gateway type, which is typically only used in multi-network multi-cluster deployments.

The TLS mode of all Gateways in the cluster can be detected with the following command:

    $ kubectl get gateways.networking.istio.io -A -o "custom-columns=NAMESPACE:.metadata.namespace,NAME:.metadata.name,TLS_MODE:.spec.servers[*].tls.mode"
    

If the output shows any AUTO_PASSTHROUGH Gateways, you may be impacted.

**Mitigation**

Update your cluster to the latest supported version:

*   Istio 1.8.6, if using 1.8.x
*   Istio 1.9.5 or up
*   The patch version specified by your cloud provider
