Describe the bug

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

Additional context

pygnssutils-1.0.17, but all versions will see the error.

The problem and the solution is described here:
https://stackoverflow.com/questions/76616042/attributeerror-module-pil-image-has-no-attribute-antialias

The following change in site-packages/pygpsclient/ solves the problem:
Out: Image.open(IMG_WORLD).resize((w, h), Image.ANTIALIAS)
In: Image.open(IMG_WORLD).resize((w, h), Image.LANCZOS)

Problem started with upgrade from Pillow-9.5.0 to pillow-10.2.0
ANTIALIAS was removed in Pillow 10.0.0 (after being deprecated through many previous versions).

Hi @japs386

Sorry but I’m unclear where exactly you’re seeing this error. The pygnssutils library doesn’t use Pillow and as far as I’m aware PyGPSClient no longer uses the ANTIALIAS flag. Can you clarify which version of PyGPSClient you’re seeing this in and provide the FULL error traceback please. Thanks

You’re using a very old version - the issue you’re referring to was addressed back in 1.3.28. I strongly recommend upgrading to the latest version 1.4.8.

python3 -m pip install —upgrade pygpsclient

If you’re able, I also recommend installing Python 3.12, which offers some worthwhile performance improvements.

I just did a few minutes ago, but pygpsclient/map_frame.py still contains
Image.open(IMG_WORLD).resize((w, h)) # , Image.ANTIALIAS)
It may give rise to some confusion. Anyway problem solved.

Not sure why a comment would cause confusion, but happy to remove it in next release.

Assuming you’ve upgraded, are you happy to close the issue?
