Support for Tk/Tcl 8.4 is deprecated and will be removed in Pillow 10.0.0 (2023-01-02), when Tk/Tcl 8.5 will be the minimum supported.
TODO
If IPython is present, this new 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 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 ImageShow will stay the same for most Pillow users.
TODO
Support has been added for PyQt6. If it is installed, it will be used instead of PySide6, PyQt5 or PySide2.
