Only if you apply it on a square image.

Not sure how you're rounding things here, but PIL's thumbnail method
does indeed preserve the aspect ratio:
>>> from PIL import Image
>>> im = Image.new("RGB", (500, 635))
>>> im.size
(500, 635)
>>> im.thumbnail((250, 250))
>>> im.size
(197, 250)
>>> im = Image.new("RGB", (625, 500))
>>> im.size
(625, 500)
>>> im.thumbnail((250, 250))
>>> im.size
(250, 200)
>>>
