可以在Kivy中的图像圆形边缘吗？

我对我的代码有疑问，找不到任何答案，所以我来了。有人知道是否可以在Kivy中绕过图像的边缘吗？我不是指舍入按钮的边缘。

我的图像代码：

    Image:
        source: 'assets/images/banner/purple.jpeg'
        keep_ratio: True
        height: 250
        width: 350
        center_x: root.width / 2
        center_y: 575

PS尝试使用边框属性。没有错误，但图像也没有变化:(

原文

I had a question about my code and couldn't find any answers so I came here. Does anyone know if it is possible to round the edges of an image in kivy and how? I am not referring to rounding a button's edges.

My image code:

    Image:
        source: 'assets/images/banner/purple.jpeg'
        keep_ratio: True
        height: 250
        width: 350
        center_x: root.width / 2
        center_y: 575

P.S. Tried using the border property. No errors but no change in the image either :(

在这种情况下，最好的解决方案是用椭圆形成画布：

kivy doc：

.kv

canvas:
        Color:
            rgb: 1, 1, 1
        Ellipse:
            pos: 100, 100
            size: 200, 200
            source: 'assets/images/banner/purple.jpeg'
            angle_start: 0
            angle_end: 360

我也建议您查看

动态类：
https://kivy.org/doc/doc/stable/stable/api--kivy.lang。 html

导入，设置并包括：
https://kivy.org/doc/doc/stable/guide/guide/guide/lang.htm.html.html

这将帮助您保持主KV文件尽可能小。因此，您也有变量，例如文本颜色和内容，因此您只需要在一个地方进行更改即可。

希望它有帮助

In this case the best solution would be to do a canvas with a Ellipse:

kivy doc:
https://kivy.org/doc/stable/examples/gen__canvas__circle__py.html

.kv

canvas:
        Color:
            rgb: 1, 1, 1
        Ellipse:
            pos: 100, 100
            size: 200, 200
            source: 'assets/images/banner/purple.jpeg'
            angle_start: 0
            angle_end: 360

I would suggest also looking at

Dynamic Classes:
https://kivy.org/doc/stable/api-kivy.lang.html

import, set and include :
https://kivy.org/doc/stable/guide/lang.html

this would help you keep your main kv file as small as possible. And also so you have variables for example text colors and stuff so you only need to change in one place.

Hope it helps
