将图片文件名映射到图片编号上

Question

我正在寻找一种方法来在图形文件名和其图形编号之间建立映射。您可以在下面找到 MWE，其中指定了所需的输出。

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

\begin{document}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Some code that provides the same output as the following fragment:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Figure map:
\begin{itemize}
\item Figure 1: example-image-a
\item Figure 2: example-image-b
\item Figure 3: example-image-c
\end{itemize}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

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

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

\begin{figure}
\centering
\includegraphics{example-image-c}
\label{fig:gimel}
\caption[Gimel figure.]{Gimel.}
\end{figure}

\end{document}

次优解决方案发布于获取单个图形文件的标题编号，但有时我需要使用, []\listoffigures参数来生成真正的目录\caption。

我想过创建一个副本\listoffigures，但这似乎不可行（修改命令以获取替代图表列表）。

Answer 1

在另一个主题中（如何对按图号索引的列表进行排序？）您要求采用更自动化的方式来完成此任务。

既然你说这是一份要发送给出版商的清单，我认为目标不是将文本包含在实际文档中。因此，我认为最好将这些数据注销到辅助文件中。

添加你的序言

并像平常一样使用您的图形和子图形。

这将创建一个包含

Figure 1: example-image-a
Figure 2a: example-image-b
Figure 2b: example-image-c

如果您的文档名为document.tex，则该文件名为document_figures.txt，即_figures.txt附加在其后面。

这就是你想要的吗？

Answer 2

这是一个可能的方法。请注意，\label应该后標題。
