获取单个图形文件的标题编号

Question

我想列出乳胶文档图表的标题编号。我的 MWE 如下：

\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

\begin{document}

\begin{figure}
\centering
\includegraphics{fig_alef.jpg}
\label{fig:fig_alef}
\caption{Alef.}
\end{figure}

\begin{figure}
\centering
\includegraphics{fig_bet.jpg}
\label{fig:fig_bet}
\caption{Bet.}
\end{figure}

\begin{figure}
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{fig_gimel.jpg}
    \label{fig:fig_gimel}
    \caption{Gimel.}
    \end{subfigure}
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{fig_dalet.jpg}
    \label{fig:fig_dalet}
    \caption{Dalet.}
    \end{subfigure}
    \caption{Gimel + dalet.}
\end{figure}

\appendix
\renewcommand{\thefigure}{A\arabic{figure}}
\setcounter{figure}{0}

\begin{figure}
\centering
\includegraphics{fig_he.jpg}
\label{fig:fig_he}
\caption{He.}
\end{figure}

\end{document}

期望的输出是这样的：

\label{fig:fig_alef}: Figure 1
\label{fig:fig_bet}:  Figure 2
\label{fig:fig_gimel}: Figure 3 [perhaps with (a) - not so important]
\label{fig:fig_dalet}: Figure 3 [perhaps with (b) - not so important]
\label{fig:fig_he}: Figure A1

是否可以以某种方式提取图形标签和标题编号之间的对应关系？

Answer 1

您想要的大部分内容都由 完成\listoffigures。您可以使用 的可选参数来控制内容\caption。您还可以修改\l@figure（目前仅调用\@dottedtocline）。

\documentclass{article}

\usepackage{caption}

\captionsetup[subfigure]{list=true}

\begin{document}

\listoffigures
\newpage

\begin{figure}
\centering
\includegraphics{example-image-a}
\label{fig:fig_alef}
\caption[\figurename~\thefigure]{Alef.}
\end{figure}

\begin{figure}
\centering
\includegraphics{example-image-b}
\label{fig:fig_bet}
\caption[\figurename~\thefigure]{Bet.}
\end{figure}

\begin{figure}
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{example-image-c}
    \label{fig:fig_gimel}
    \caption[\figurename~\thefigure\thesubfigure]{Gimel.}
    \end{subfigure}
    \begin{subfigure}[]{\textwidth}
    \centering
    \includegraphics[width=\textwidth]{example-image}
    \label{fig:fig_dalet}
    \caption[\figurename~\thefigure\thesubfigure]{Dalet.}
    \end{subfigure}
    \caption[\figurename~\thefigure]{Gimel + dalet.}
\end{figure}

\appendix
\renewcommand{\thefigure}{A\arabic{figure}}
\setcounter{figure}{0}

\begin{figure}
\centering
\includegraphics{example-image-duck}
\label{fig:fig_he}
\caption[\figurename~\thefigure]{He.}
\end{figure}

\end{document}

这显示了如何从头开始创建图形列表。请注意，条目的顺序与\modcaptions 的顺序相同。
