kivy.atlas

[Allan Mabe]

I am trying to use kivy.atlas to make an atlas of images, but I keep getting the following error:

python -m kivy.atlas myatlas 256x256 *.png

What am I doing wrong here?

I am using arch linux and have python 3.4 installed by default, but I also have python 2 installed. I also installed the Pillow library.

Looks like this is a python3 bug - the code expects that map returns a list, but now it returns an object. I've created a PR (https://github.com/kivy/kivy/pull/3482) to fix this in the master branch.

In the meantime, it's probably easiest to make the atlas with python2 if you have that available, though you'd need kivy installed for that python. You could also modify the atlas source in the same way as my PR (it's just 2 small changes), I suppose that should have no bad side effects since when kivy is upgraded this fix will hopefully already have been merged.

Thanks, that worked out.
