我正在尝试调整一些图像的大小,其中大多数是JPG。但是在一些图像中,我得到了错误:
Traceback (most recent call last): File "image_operation_new.py", line 168, in modifyImage tempImage.save(finalName); File "/Users/kshitiz/.virtualenvs/django_project/lib/python2.7/site- packages/PIL/Image.py", line 1465, in save save_handler(self, fp, filename) File "/Users/kshitiz/.virtualenvs/django_project/lib/python2.7/site- packages/PIL/JpegImagePlugin.py", line 455, in _save raise IOError("cannot write mode %s as JPEG" % im.mode) IOError: cannot write mode P as JPEG
我没有更改图像类型,而是使用了枕头库。我的操作系统是Mac OSX。如何解决该问题?
您需要将图像转换为RGB模式。
Image.open('old.jpeg').convert('RGB').save('new.jpeg')
