ImageDraw.ellipse() with square bounding box doesn't produce circle

[gronostajo]

The code below should produce a circle:

>>> from PIL import Image, ImageDraw
>>> box = (20, 20, 40, 40)
>>> im = Image.new('L', (60, 60), 0)
>>> draw = ImageDraw.Draw(im)
>>> draw.ellipse(box, 255)
>>> im.show()

The result isn't a 20x20 px circle as expected, but 21x20 px ellipse:

I'm using Pillow 2.2.2.

Got a pull request to fix this? Any idea where the regression is?

[wiredfool]

It's at least back to Pillow 1.7.8

[aclark4life]

Now targeting 2.4.0

Reproducible with Pillow 1.76 and PIL 1.1.7 on Python 2.7/Windows.

Reproducible with PIL 1.1.4 on Python 2.3/Windows, the oldest PIL here.

2.5.0 time!

[aclark4life]

What's going on here?

[hugovk]

@aclark4life I expect this will be fixed when @Terseus' work is finalised in #610. Currently awaiting further feedback from @wiredfool [https://github.com//pull/610#issuecomment-42601238].

Ah, thanks @hugovk

#610 superseded by #737
