Django，sorl-thumbnail裁剪图片头 [英] Django, sorl-thumbnail crop picture head

问题描述

我想知道如果sorl-thumbnail有从下到上的选择...我有一个垃圾问题，在一些图片中，缩略图是在图片中的人物的头上。

谢谢

解决方案

我刚刚发布了一个新版本由btol45的答案灵感来自边缘和智能裁剪的sorl-thumbnail（3.2.5）。

引用文档：

默认情况下，图像在裁剪前居中。要从
边缘裁剪，请传递一个逗号分隔的字符串，其中包含 x 和 y
百分比偏移量（负值从右侧/底部）。一些
的例子如下：

• crop =0,0将从左边和上边缘裁剪。




• crop = - 10，-0将从正确的边缘（10％的偏移量）和
  的边缘裁剪。




• crop = ，0将保持x轴的默认行为（水平
  以图像为中心），并从上边缘裁剪。

图像也可以通过使用 crop =smart进行智能裁剪。图像
通过从最小熵的边删除切片
，逐渐裁剪到所请求的大小。

guys, i would like to know if sorl-thumbnail have any option to crop from the bottom to the top... i have a litter problem, in some picture sorl-thumbnail is croping the head of the people in pictures.

Thanks

解决方案

I've just released a new version of sorl-thumbnail (3.2.5) with cropping from edge and smart cropping inspired by btol45's answer.

Quoting the docs:

By default, the image is centered before being cropped. To crop from the edges, pass a comma separated string containing the x and y percentage offsets (negative values go from the right/bottom). Some examples follow:

• crop="0,0" will crop from the left and top edges.

• crop="-10,-0" will crop from the right edge (with a 10% offset) and the bottom edge.

• crop=",0" will keep the default behavior for the x axis (horizontally centering the image) and crop from the top edge.

The image can also be "smart cropped" by using crop="smart". The image is incrementally cropped down to the requested size by removing slices from edges with the least entropy.
