Why does Pillow not recognize the JPEG format?

anaconda, python, python-imaging-library

Solution

Turned out that Eclipse was using PIL rather than Pillow: I just deleted the PIL library reference in Eclipse and made sure Pillow was being used instead and it ran fine.

Problem

Trying out this simple code to write text on an image: ``` import ImageFont import Image import ImageDraw font = ImageFont.truetype("arial.ttf", 16) img=Image.new("RGB", (200,200),(120,20,20)) draw = ImageDraw.Draw(img) draw.text((0, 0),"This is a test",(255,255,0),font=font) draw = ImageDraw.Draw(img) img.save("C:/Users/User/Desktop/test","jpeg") ``` and I get this error: ``` File "C:\Users\User\Anaconda\lib\site-packages\PIL\Image.py", line 1456, in save save_handler = SAVE[format.upper()] # unknown format KeyError: 'JPEG' ``` Any idea of how to fix this? I am using Python 2.7.5 Anaconda version in Windows 7 with Eclipse Kepler and PyDev plugin. I also tried `img.save("test.jpeg")` and `img.save("test.png")` resulting in the same error.
