我编写了一个小程序,将 webp 转换为python中的jpg
import imghdr
from PIL import Image
im = Image.open("unnamed.webp").convert("RGB")
im.save("test.jpg","jpeg")
执行时会出现以下错误
No handlers could be found for logger "PIL.ImageFile"
Traceback (most recent call last):
File "webptopng.py", line 3, in <module>
im = Image.open("unnamed.webp").convert("RGB")
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 2286, in open
% (filename if filename else fp))
IOError: cannot identify image file 'unnamed.webp'
我已经安装了具有webp功能的枕头。这是我的枕头安装输出

我使用webp图像测试了你的代码,它适用于Pillow 2.9:
$ wget https://www.gstatic.com/webp/gallery3/2_webp_a.webp
>>> from PIL import Image
>>> im = Image.open("2_webp_a.webp").convert("RGB")
>>> im.save("test.jpg","jpeg")
Pillow 3.0问题#1474与您的错误有关。
让我们尝试将Pillow从3.0降级到2.9,然后重试。

此问题现已解决。我已安装最新的libwebp库i,e libwebp-0.4.3并重新安装枕头。
Here是github问题线程,如果有人遇到同样的问题。

pip install webptools
安装 webptools 然后:
from webptools import dwebp
print(dwebp("python_logo.webp","python_logo.jpg","-o"))
该库的工作速度有点慢,但是很容易完成您的工作。
