我使用Python 2.7 / Django 1.9和Pillow 4.1.1。
我的网站上有成千上万张用户上传的图片,我使用Pillow从模板生成缩略图。
例如:
{% thumbnail apicture.file "1200x350" crop="center" as im %}
<img src="{{ im.url }}" width=100%>
{% endthumbnail %}
直到本周前,它一直运行得非常好。Django现在显示以下错误:
IOError: image file is truncated (6 bytes not processed)
在stackoverflow上找到的解决方案都不起作用,因为它们都适用于视图而不是模板(例如ImageFile.LOAD_TRUNCATED_IMAGES = True)。
有没有一种简单的方法来识别哪些图片会生成此错误?如何解决这个问题?

谢谢您
ImageFile.LOAD_TRUNCATED_IMAGES = True
即可。 - lepsch
