精確選擇節點之間的線的出發點

2024-6-19 • tag-icon

我想在這些錨點之間的某個位置選擇節點之間的線的出發點，例如我想選擇東北和東之間的錨點。我怎樣才能做到這一點？

您可以用來nodename.angle指定節點邊緣的線應開始的位置：

\documentclass{article}
\usepackage{tikz}

\begin{document}

    \begin{tikzpicture}
      \node[draw,minimum height=2cm,minimum width=2cm] (Abonné) {Abonné};
      \draw (Abonné.25) -- ++ (2,2);
    \end{tikzpicture}

\end{document}
