Why does Pillow not recognize the JPEG format?

Question

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.

Answer 1

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.

Answer 2

Try just running

img.save("test.jpg")

and see if that does the trick. You shouldn't have to specify the type of file if you also supply a valid extension.
