I am not able to use any attribute (eg. get_size() or resize) on a Willow Image instance. It seems these attributes are not available on the Image subclass (here: JPEGImageFile). I tried the code samples from the README but I must have taken a wrong turn somewhere and can't find my mistake ;-)
I'm using Willow 1.4.1
from willow.image import Image
f = open("/tmp/foo.jpg", "rb")
img = Image.open(f)
img
<willow.image.JPEGImageFile object at 0x7fc7445d2c10>
img.get_size()
AttributeError: 'JPEGImageFile' object has no attribute 'resize'
