![使用 tikz spath3 和 *nodes*](https://linux22.com/image/442575/%E4%BD%BF%E7%94%A8%20tikz%20spath3%20%E5%92%8C%20*nodes*.png)
我可以使用 spath3路径(不是节点) 这样:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{spath3, intersections}
\begin{document}
\begin{tikzpicture}
\draw[spath/save = rect, rounded corners=12pt] (0,0) rectangle (2,1);
\draw[spath/save global = line3] (-1,-1) -- (0.4,0.75);
\draw[spath/save global = line4] (-1,-1) -- (1,0.5);
\tikzset{spath/.cd,
split at intersections with={rect}{line3},
split at intersections with={rect}{line4},
get components of={rect}\cpts
}
\draw[ultra thick, color=red, spath/restore=\getComponentOf\cpts{3}] node {};
\end{tikzpicture}
\end{document}
结果:
到目前为止,一切都很好。
但我真正需要的是用双线突出显示交叉点处矩形节点的一部分,但它不起作用:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{spath3, intersections}
\begin{document}
\begin{tikzpicture}
\node[spath/save global = rect, rectangle, rounded corners=12pt, draw=black!50, thick, fill=white, minimum height=27pt] {asdfasdfasdfasdf};
\draw[spath/save global = line, line width=1pt, double=white, draw=black!20, double distance=3pt] (-2, -1) -- (-0.5,0.0);
\tikzset{spath/.cd,
split at intersections with={rect}{line},
split at intersections with={rect}{line},
get components of={rect}\cpts
}
\draw[ultra thick, color=red, spath/restore=\getComponentOf\cpts{2}] node {};
\end{tikzpicture}
\end{document}
有任何想法吗?
