如何缩放外部文件中的 tikzpicture 以用于投影仪幻灯片？

Question

你不应该\usetikzlibrary{mindmap,shadows}在序言之外使用。要包含具有指定宽度的思维导图，只需使用

\includestandalone[width=.75\linewidth]{mindmap}

subpreambles如果包选项设置为，则可以使用所包含文件的前言true。

如果您只绘制图像，您可能希望用替换\documentclass{article}。\documentclass{standalone}

请尝试创建 MWE。主文档和大树中的所有格式都没有真正的理由

您的代码可能如下所示：

主文本

\documentclass{beamer}
\usepackage[subpreambles=true]{standalone}
\usepackage{tikz}


\usepackage{lipsum}

\usecolortheme{wolverine}
\setbeamertemplate{headline}{inflines theme}
\setbeamertemplate{footline}{infolines theme}

\setbeamertemplate{headline}{%
 \hbox{%
   \begin{beamercolorbox}[wd=.25\paperwidth]{section in head/foot}%
   \end{beamercolorbox}%
   \begin{beamercolorbox}[wd=.75\paperwidth]{section in head/foot}%
   \end{beamercolorbox}%
 }%
}%

\defbeamertemplate*{footline}{infolines theme}{\relax
  \leavevmode%
  \hbox{\relax
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
  \end{beamercolorbox}}%
  \vskip0pt%
}

\begin{document}
  \begin{frame}\frametitle{Frame Title}
       \centering
       \includestandalone[width=.75\linewidth]{mindmap}

   \end{frame}
\end{document}
