sorl-thumbnail：编写图像文件时的编码器错误-2

问题描述

我一直在使用sorl-thumbnail一段时间没有问题。但是，以下错误开始出现：编写图像文件时的编码器错误-2 。

I've been using sorl-thumbnail for some time without problems. However, the following error started to appear: encoder error -2 when writing image file.

以下代码导致错误：

from sorl.thumbnail import get_thumbnail
photobooth_thumbnail = get_thumbnail(img_file,
    PHOTOBOOTH_THUMB_SIZE, crop='center', quality=99)

正在 img_file 一个Django模型的ImageField，当 PHOTOBOOTH_THUMB_SIZE 是足够大时。当我使用 PHOTOBOOTH_THUMB_SIZE ='670'时，一切正常，但当我将其增加到 PHOTOBOOTH_THUMB_SIZE ='1280'，出现上述错误。

being img_file a Django models' ImageField and when PHOTOBOOTH_THUMB_SIZE is "sufficiently large". When I was using PHOTOBOOTH_THUMB_SIZE = '670', everything worked just fine, but when I increased it to PHOTOBOOTH_THUMB_SIZE = '1280', the aforementioned error appeared.

我怀疑这是PIL中的错误，而不是在sorl-thumbnail中，给定低级消息。我想要更大的缩略图，所以我很乐意为此提供任何帮助。感谢提前。

I'm suspecting this is an error in PIL rather than in sorl-thumbnail, given the low level message. I'd like to have bigger thumbnails, so I'd appreciate any help on this. Thanks in advance.

我最后补丁文件 pil_engine.py 在 /lib/python2.7/site-packages/sorl/thumbnail/engines ：

这解决了我的问题。
