scrreprt 拇指索引與 scrlayer-scrpage：使用任何形狀作為chapterthumb

我想使用與矩形不同的形狀作為chapterthumb-symbol，即圓形或帶有圓角的菱形。使用 scrlayer-scrpage 和雙面 scrreprt 設定是否可以實現這一點？我看到可以使用 Tikz 在 LaTeX 中繪製形狀，我如何使用我的設定來實現這一點？

如果您想要帶有圓角的菱形，請\usetikzlibrary{backgrounds}在後面添加\usepackage{tikz}並\begin{tikzpicture} ... \end{tikzpicture}%用以下內容替換該部分：

\begin{tikzpicture}
  \node[inner sep=2.5ex] (n) {\chapterthumbformat};
  \begin{scope}[on background layer]
    \path[fill=chapterthumbboxcolor, rounded corners=2pt]
      (n.north) -- (n.west) -- (n.south) -- (n.east) -- cycle;
  \end{scope}
\end{tikzpicture}%
