对于包含大量图片的图书项目，我需要生成包含的所有图片的文件名列表，方法是includegraphics{} 及其图号。 就像是：
1.1 ch01-intro/fig/lascaux.jpg
1.2 ch01-intro/fig/plot-weather-new.png
1.3 ch01-intro/fig/huygens1669.png
1.4 ch01-intro/fig/priestley-chart-biography-edit.png
CTAN 上有一段perl脚本，泰克森，它将找到文件名，但它不一定按顺序列出它们，也不会理解图号。（它旨在生成Makefile或为 LaTeX 项目准备 ZIP 文件。）
> texdepend -format=1 -print=f TOGS.tex |head
# C:\batchfiles\texdepend.pl, v0.96 (Michael Friendly ([email protected]))
# commandline: C:\batchfiles\texdepend.pl -format=1 -print=f TOGS.tex
# FIGS =
ch05-playfair/fig/playfair1805-inquiry-crop.jpg
ch01-intro/fig/lascaux.jpg
ch01-intro/fig/plot-weather-new.png
ch01-intro/fig/huygens1669.png
ch01-intro/fig/priestley-chart-biography-edit.png
ch01-intro/fig/marey-trains.png
ch01-intro/fig/Minard-cotton3.png
通缉：一种修改includegraphics自身的方法，以便它也将行写入外部文件，形式如下
fignum filename
一个小的复杂因素是给定的begin{figure}环境可以包含两个或多个\includegraphics命令，例如：
\begin{figure}[htb]
\centering
\includegraphics[width=.49\textwidth]{\theChapter/fig/galton-interp2}
\includegraphics[width=.49\textwidth]{\theChapter/fig/galton-interp3}
\caption{A reconstruction of Galton's method for finding contours of
approximately equal frequency in the relationship between heights of parents
and their children.
}%
\label{fig:galton-interp2}
\end{figure}
如果生成图 6.16，结果应该如下所示
6.16 ch06-scat/fig/galton-interp2.png
6.16 ch06-scat/fig/galton-interp3.png
答案1
\includegraphics通过在末尾添加更多代码来重新定义，人为地增加figure数量（在一组内）并写入ToC类似文件，以获得文件句柄机制\addtocontents的好处。ToC\tf@...
该文件将被命名，并且只有在使用\jobname.lfn时才会写入。\listoffigurenumbernames
删除demo实际用例的选项，我把它放在那里是因为我的磁盘上没有各种图形文件。

这给出
1.1 1/fig/galton-interp2
1.1 1/fig/galton-interp3
1.2 1/fig/galton-interp4
1.2 1/fig/galton-inter5
2.1 2/fig/galton-interp6
2.1 2/fig/galton-inter7
改良版
使用启发式方法确定文件扩展名.jpg，.pdf或.pdf
该\includegraphics宏有第四个可选参数，可用于覆盖文件扩展名。
