我正在尝试使用 moodle.sty 包，但对图像有疑问。问题是生成的 xml 文件对图像不正确（当我查看 Moodle 中的 html 代码时，我得到的是“”。base64 之后缺少图像，我的 tex 文件如下
提前感谢你的帮助

这在很大程度上取决于你使用的平台。我的经验是使用 Linux。基本上
我不知道你为什么要修改内部命令。我的 Moodle 可以正常工作，包括图像……只要你使用全名（我知道，我知道，不应该这样，但是……）就像
\includegraphics{myfig.pdf}。尽管有补丁可以修复它，但图形必须与主文件位于同一目录中。
你必须用旗帜来呼叫解释器
--shell-escape。lualatex如果您的文本中包含任何重音字符，则效果会更好（嗯，有效，因为没有pdflatex它就不会）。我被这个咬了
imagemagick过于热心的设置找到它真是一件令人痛苦的事……
我希望这有帮助...
举个例子。我把这个图保存为fullrect.png：
并且此代码在testquiz.tex：
% vim: set spelllang=es :
%! TEX program = lualatex
%
\documentclass{article}
\usepackage{graphicx}
\usepackage{moodle}
\moodleset{ppi=200}
\begin{document}
\begin{quiz}{Rectificadores} % Nombre del banco de preguntas
\begin{multi}{Medida del termopar}
\includegraphics[width=10cm]{fullrect.png}
A ver, supon que tienes este circuito arriba. El valor medio de la tensión a la salida $u_1$ es \dots
\item* positivo
\item negativo
\item nulo
\end{multi}
\end{quiz}
\end{document}
我编译时使用：
lualatex --shell-escape testquiz.tex
testquiz-moodle.xml生成一个文件，其中包含：
是的，分辨率很低，但我有一个提高分辨率的技巧，如果你需要的话可以问问。
