tikz 独立版不显示绘制的箭头

Question

我使用 standalone 绘制了一些箭头来注释图形。但是，当我输入 [tikz]{standalone} 时，箭头不显示。如果我使用 report 或删除 [tikz]，则箭头会显示出来，但是，我希望图形在各自的页面上分开。我该如何实现这一点？感谢您的时间。

\documentclass[tikz]{standalone}
\usepackage{graphicx}
\usepackage{pgfplots,tikz}
\usepackage{textcomp}
\usepackage{fixltx2e}
\usetikzlibrary{shapes,arrows,calc,backgrounds}

\pagestyle{empty}
\begin{document}


\tikzstyle{line} = [draw, -latex']
\tikzstyle{every picture}+=[remember picture] 

\begin{tikzpicture}
\node [anchor=south, inner sep=0pt]{\includegraphics[width=4cm]{./graphics/imdligand.pdf}};
\node [anchor=west] (ligand) at (3,2.9) {2x L\textsubscript{IMD}};

\node [anchor=east] (top) at (0.35,4.56) {};
\node [anchor=east] (bottom) at (0.98,1.29) {};
\end{tikzpicture}

\begin{tikzpicture}[overlay]
\path [line,black,thick] (ligand) |- node {}(top);
\path [line,black,thick] (ligand) |- node {}(bottom);
\end{tikzpicture}

\begin{tikzpicture}
\node[anchor=south,inner sep=0pt]{\includegraphics[width=4cm]{./graphics/pyrligand.pdf}};
\node[anchor=west] (ligand2) at (3,4.3) {2x L\textsubscript{PYR}};

\node[anchor=east] (top1) at (0.85,5.9) {};
\node[anchor=east] (bottom2) at (0.85,2.6) {};
\end{tikzpicture}

\begin{tikzpicture}[overlay]
\path [line,black, thick] (ligand2) |-node{}(top1);
\path [line,black,thick] (ligand2) |-node{}(bottom2);
\end{tikzpicture}

\end{document}

Answer 1

当您使用该类的选项时，每个选项tikzpicture都会开始一个新页面。这样可以防止图片出现，因为没有任何东西可以覆盖它。tikzstandaloneoverlay

为了避免这种情况，只需将箭头包含在tikzpicture相关图形的环境中。

例如：

\documentclass[tikz,multi,border=10pt]{standalone}
\usetikzlibrary{arrows}
\begin{document}
\tikzset{% \tikzstyle is deprecated
  line/.style = {draw, -latex'}}

\begin{tikzpicture}
  \node [anchor=south, inner sep=0pt]{\includegraphics[width=4cm]{example-image-a}};
  \node [anchor=west] (ligand) at (3,2.9) {2x L\textsubscript{IMD}};
  \node [anchor=east] (top) at (0.35,4.56) {};
  \node [anchor=east] (bottom) at (0.98,1.29) {};
  \path [line,black,thick] (ligand) |- node {}(top);
  \path [line,black,thick] (ligand) |- node {}(bottom);
\end{tikzpicture}

\begin{tikzpicture}
  \node[anchor=south,inner sep=0pt]{\includegraphics[width=4cm]{example-image-b}};
  \node[anchor=west] (ligand2) at (3,4.3) {2x L\textsubscript{PYR}};
  \node[anchor=east] (top1) at (0.85,5.9) {};
  \node[anchor=east] (bottom2) at (0.85,2.6) {};
  \path [line,black, thick] (ligand2) |-node{}(top1);
  \path [line,black,thick] (ligand2) |-node{}(bottom2);
\end{tikzpicture}

\end{document}
