python之pygame 的字体渲染代码中的抗锯齿是什么意思

class Score(pygame.Surface):    
 
pygame.font.Font.render(Text, antialias, color, Background)  

我正在尝试编写一个代码来实现一个文本文件，该文件会出现在我的 pygame 界面上。我希望它显示在屏幕的右上角。我的问题是我不了解抗锯齿的作用以及我在抗锯齿代码点上放了什么。我是放一个 Int 还是某种 String。这里有更多的代码来展示，只是为了让您了解我要做什么。我希望这有助于得到我的答案。

请您参考如下方法:

antialias 参数是一个 bool 值。如果为真，字符将具有平滑的边缘。您可以在文档中阅读相关信息。
