在多個頁面上繪製 TikZ 箭頭

Question

我希望在頁邊註之間有箭頭，我透過\tikzmarknode（圖 1）實現了這一點。但如果一個標記位於另一頁上，則該方法不起作用（圖 2）。

我想要的是一條連續的線，一直延伸到頁面末尾，然後重新出現在下一頁的頂部（圖 3）。

微量元素：

\documentclass[10pt,oneside]{scrbook}
\usepackage{lipsum}
\usepackage[left=32.5mm, right=22.5mm, top=25mm, bottom=20mm, marginparsep=3mm]{geometry}
\usepackage{tikz}
    \usetikzlibrary{tikzmark}
\usepackage{marginnote}
\renewcommand*{\marginfont}{\footnotesize\itshape}

\begin{document}

\marginnote{\tikzmarknode{a}{Thermoplast}}
\lipsum[1]
\marginnote{\tikzmarknode{b}{teilkristallin}}
\lipsum[1]
\marginnote{\tikzmarknode{c}{aliphatisch}} 
\begin{tikzpicture}[remember picture, overlay, shorten >=1.5mm, shorten <=1.5mm,->]
    \draw ([xshift=10pt]a.south west) to ([xshift=10pt]b.north west);
    \draw ([xshift=10pt]b.south west) to ([xshift=10pt]c.north west);
\end{tikzpicture}
% \lipsum[1-6]    % Works fine
\lipsum[1-7]    % Doesn't work
\marginnote{\tikzmarknode{d}{aliphatisch}} 
\begin{tikzpicture}[remember picture, overlay, shorten >=1.5mm, shorten <=1.5mm,->]
    \draw ([xshift=10pt]c.south west) to ([xshift=10pt]d.north west);
\end{tikzpicture}

\end{document}

Answer 1

圖書館tikzmark附有一張支票\iftikzmarkoncurrentpage。這使我們能夠區分情況

1. 目前頁面上沒有任何節點（目前頁面可能位於兩個要連接的後續標記的頁面之間），
2. 當前頁面的第一個節點，
3. 目前頁面上的第二個節點，
4. 兩個節點都在同一頁上。

這些情況在巨集中區分\ConnectTikZmarknodes，巨集也透過分頁符號連接節點。它用於eso-pic避免要求用戶在多個頁面上添加巨集。由於附帶的良好檢查，tikzmark可以（並且，如果連接運行在多個頁面上，也是必要的）\ConnectTikZmarknodes在實際定義節點之前添加。
