Python PIL是否有抗锯齿方法? [英] Is there an antialiasing method for Python PIL?

问题描述

对于PIL中的线条和椭圆，图像是粗糙的.​​

For lines and ellipses in PIL, the images are rough.

我发现只有在调整大小和缩略图时才具有抗锯齿功能.

I found antialiasing only in resize and thumbnail.

画线或椭圆时有什么方法可以进行抗锯齿吗?

Is there any way to do antialiasing when drawing a line or ellipse?

推荐答案

本地执行此操作的唯一方法是超级采样.以所需大小的倍数渲染图像，然后用filter=Image.ANTIALIAS resize渲染图像.

The only way to do it natively is with supersampling. Render your image at a multiple of the size you require, then resize it with filter=Image.ANTIALIAS.
