语境

Question

我想自动生成我的内容幻灯片投影机，我使用 TikZ 对其进行了自定义。我目前手动进行。

语境

我的目标是创造自己的beamer风格。这就是为什么我为我的框架定义了布局内容—见下方左侧：

该框架结构如下：见上文，对：

• 我定义一条斜线(A) -- (B)——看到红点
• 在这条线上，我定义了两点：(top)和(down)——看到蓝点
• 然后，章节编号和标题均匀分布在这条线上，在(top)和(down)边界之间——参见黄点，以及下方的一节和两节的情况。
  

问题

然而，整个结构都是手动定义的。我怎样才能自动生成这样的框架？

我看到了两个子问题：

• 生成点(one)、(two)等。
  计算它们的位置相当容易，因为它们的定义如下\node [yellow] (Number) at ($(top)!X!(down)$) {};：x = <section number> / (<total number of sections> +1)

• \thesection使用和生成标签的节点\secname（后者发现得益于这个问题) 为每个部分。

Answer 1

我的理解是您正在创建目录。因此，合理的方法是设置 toc 样式并包含该.toc文件。

@samcarter 建议采用一种更好的方法来捕获节的总数。但我选择了一种更粗暴的方法来演示可以包含.toc多次并实现各种目标。

在https://tex.stackexchange.com/a/260647/51022我曾演示过类似的方法。
