Convert images to webP using Pillow

问题:

I'm trying to convert .jpg images to webp format using PIL.

I'm using the this code:

from PIL import Image import glob, os  for infile in glob.glob("*.jpg"):     file, ext = os.path.splitext(infile)     im = Image.open(infile).convert("RGB")     im.save(file + ".webp", "WEBP") 

But I get the following error on running it:

Traceback (most recent call last):   File "webp.py", line 7, in <module>     im.save(file + ".webp", "WEBP")   File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1444, in save     save_handler = SAVE[format.upper()] # unknown format KeyError: 'WEBP' 

Kindly help me fixing it. I have installed libwebp-dev.

>>> import PIL >>> dir(PIL) ['PILLOW_VERSION', 'VERSION', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '_plugins'] >>> PIL.PILLOW_VERSION '2.2.1' >>> PIL.VERSION '1.1.7'

Make sure to install WEBP dev library for your OS. For Debian/Ubuntu it's libwebp-dev. You may need reinstall Pillow as well. In the output of Pillow install log you should see:

--- WEBP support available
