根据文章自动生成 Beamer 演示文稿草稿

我有一篇包含多个章节、小节和图表的 LaTeX 论文。我用来展示这篇论文的幻灯片大部分都包含相同的章节、小节和图表。因此，我有兴趣自动生成具有以下功能的演示文稿草稿的 Beamer 代码：

  • 论文的章节和小节都保存在幻灯片中。
  • 当论文的某个小节中引用某个图表时，该图表将插入到相应小节的幻灯片中。

我想知道是否已经存在类似的东西。否则，编写一个脚本来解析论文并生成 Beamer 草稿将相当简单。

为了进一步阐明我的问题，我举了以下例子：

纸：

\documentclass{article}
\usepackage[affil-it]{authblk}

\author[1]{Phill}
\author[1]{Bill}
\affil[1]{Instutite of LaTeX}
\title{Paper 1}
\begin{document}
\section{sec1}
\subsection{sec1.1}

See the data in \ref{fig:1}.

\section*{Figures}
\begin{figure}
    \includegraphics[scale = 0.5]{example-image}
    \label{fig:1}
\end{figure}
\end{document}

结果幻灯片：

\documentclass{beamer}
\title{Paper 1}
\author{Phill and Bill}
\Institute{Instutite of LaTeX}
\begin{document}
\begin{frame}
 \titlepage
\end{frame}
\section{sec1}
\subsection{sec1.1}
\begin{frame}{\secname : \subsecname}
\begin{figure}
    \includegraphics[scale = 0.5]{example-image}
    \label{fig:1}
\end{figure}
\end{frame}

\end{document}

我继续编写了一个 Python 脚本来解决这个问题。本质上，Beamer 演示文稿将保留文章的格式（部分子部分），并为每个图形创建一个新幻灯片，使图形适合整个幻灯片。

要使用它，您只需在与文章文件相同的目录中运行它即可，该文件应命名main.tex为。输出演示文稿将写入slides.tex。

import os

    beamer_file_path = 'slides.tex'

就我个人而言，我更喜欢pdfscreen和。 texpowerbeamer

\documentclass{article}
\usepackage[affil-it]{authblk}
\usepackage{xspace,xcolor}
\usepackage{graphics}
\usepackage[screen,nopanel,orange]{pdfscreen}
\hypersetup{pdftoolbar=true}
\usepackage[display]{texpower}

\margins{0.25in}{0.25in}{0.25in}{0.25in}
\screensize{4.5in}{6in}% 4.5in by 8in for widescreen
\backgroundcolor{blue}
\color{white}

\author[1]{Phill}
\author[1]{Bill}
\affil[1]{Instutite of LaTeX}
\title{Paper 1}
\begin{document}
\maketitle
\section{sec1}
\subsection{sec1.1}

See the data in \ref{fig:1}.

\section*{Figures}
\begin{figure}
    \includegraphics[scale = 0.5]{example-image}
    \caption{No caption, No figure number, No label}
    \label{fig:1}
\end{figure}
\end{document}
