AttributeError exception due to backward incompatible change in Pillow 10.0.0

[pieqq]

Hello! I discovered your super handy project while trying to print labels on a Brother QL-800 from Linux. Thanks a lot for the time you spent developing this solution, it's very handy!

I installed the program by following the instructions, but ran into this problem:

 brother_ql -b pyusb -m QL-800 -p usb://0x04f9:0x209b print -l 12 ../202306-31748.png 
deprecation warning: brother_ql.devicedependent is deprecated and will be removed in a future release

AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'

This is caused by Pillow 10.0.0 which removed ANTIALIAS.

An easy fix for me was to force the installation of the previous version of Pillow, 9.5.0:

pip install --force-reinstall -v "Pillow==9.5.0"

then everything was good.

Two ways to fix this behavior:

1. Update the code (conversion.py) to use a different method as explained in the Pillow 10.0.0 changelog
2. Update the setup.py file to fix the Pillow version to 9.x.

Let me know what would be the preferred solution, I can probably help to implement this.

Cheers,

You can simply add:

from pkg_resources import parse_version
if parse_version(Image.__version__)>=parse_version('10.0.0'):
    Image.ANTIALIAS=Image.LANCZOS

after the line from PIL import Image In the conversion.py file of the brother_ql library.

Using pkg_resources will only work on Python < 3.12 by default due to dropping setuptools from the default packages in a virtual environment. The alternative is to require and use the packaging package or to just replace the usage of the old way and require Python > 3.7 (Python <= 3.7 are EOL anyway).
