Is Pillow v3 tied to python 3?

DougieLawson commented 8 years ago

Nope. It's just what I got with a stock pip install.

rm-hull commented 8 years ago

I was previously using pillow v1.7.6 Seems like tostring() is not exactly the same as tobytes() for 1-bit images

Still investigating this one...

Project has had a major overhaul, and works directly with the latest pillow version (v4.0.0)
