自动生成图形标题

我的 latex 文件中包含数百张图片。有什么方法可以自动为每张图片创建标题吗？例如，文件 picture1 会生成一个标题 picture1。

\begin{document}

\begin{figure*}[h]
        \section{Title}
    \subsection{SubTitle}
    \begin{subfigure}{0.5\linewidth}
        \includegraphics[width=\linewidth, height=0.5\linewidth]{Figure1.png}
        \caption{}
    \end{subfigure}
    \hfill
\begin{subfigure}{0.5\linewidth}
        \includegraphics[width=\linewidth, height=0.5\linewidth]{Figure2.png}
        \caption{}
    \end{subfigure}
    \hfill
\begin{subfigure}{0.5\linewidth}
    \includegraphics[width=\linewidth, height=0.5\linewidth]Figure3.png}
    \caption{}
    \end{subfigure}
    \hfill
\begin{subfigure}{0.5\linewidth}
    \includegraphics[width=\linewidth, height=0.5\linewidth]{Figure4.png}
    \caption{}
\end{subfigure}
\end{figure*}
\end{document}

通过定义新环境，可以捕获图形文件的名称并将其插入到标题中。 是

ShowSubFigure有两个参数，两个要并排显示为子图的图形的文件名。

ShowFigure同样作为两个参数：页面居中的单个图形的文件名及其宽度。

自动化替代方案

如果从操作系统生成了图形列表（如dir / b / s * .jpg > ListFig.txt），则可以自动执行该过程以生成包含所有缩略图的文档。

.csv然后构建一个（逗号分隔值）文件，每行有两个文件名，以逗号分隔。

将数据加载到数据库中（使用包datatool），然后逐行遍历，同时将文件名插入到环境中ShowSubFigure。 X

这个非常基本的示例生成了 7 页，每页 6 幅图像，按顺序编号。

\documentclass[12pt,a4paper]{article}

\usepackage{graphicx}   
\usepackage{subcaption} 

\usepackage{datatool} % added <<<<<<<<<<    
\usepackage{calculator}% added <<

\newcounter{nrow}
\setcounter{nrow}{1}

 \begin{filecontents*}[overwrite]{ImagesList.csv}

        example-image-b, example-image-b
