使用 tkz-euclide 制作的圆形图在 TeX Live 2018 和 TeX Live 2020 中的呈现方式不同

我还有另一个类似的问题我最后一个问题关于 2018 -> 2020tkz-euclide兼容性变化。

我有一个圆形图，可以在 Overleaf（TeX Live 2018）中完美编译和呈现：

以下是编译成功的代码：

但是，如果你将 TeX Live 发行版从 2018 更改为 2020，它的渲染方式会有所不同，并且 Overleaf 会出现一些错误：

我从中学到此主题不应\usetkzobj{all}与最新的 tkz-euclide 一起使用。在 2020 发行版中注释此行可修复部分问题，但并非全部问题。

一些（不希望的改变）：

  1. 在第一张图中，几何点非常大
  2. 在第一张图中，角度中有一个“刻度标记”
  3. 在第二张图中，圆的切线消失了

有什么办法可以解决这些问题吗？谢谢！

答案1

首先\usetkzobj{all}应该删除，在新版本中它会出现错误。（抱歉，没看到你提到过这一点，但它没有在代码中被注释掉。）

第二，\tkzTangent应该\tkzDefTangent

这样就修复了错误。对于不需要的更改：

  1. 如果点太大，只需更改大小\tkzDrawPoints[fill=black,size=10](O,A,B,C)，例如size=5。
  2. \tkzMarkAngle 的默认行为
  3. 往上看\tkzDefTangent。
