最近我在编译.tex文件时遇到了问题。主要是在处理或加载图像时失败，但仅限于 xelatex，而 pdflatex 可以正常工作。
以下是示例代码：
% Setting the page size and font size. %
\documentclass[a4paper,11pt]{article}
% Package used for image formating.
\usepackage{graphicx}
\graphicspath{ {"img"} }
\begin {document}
\includegraphics[width=0.3 \textwidth, keepaspectratio]{"elasticjawcoupling.png"}
\end{document}
这是使用 xelatex 编译时的输出消息：
This is XeTeX, Version 3.141592653-2.6-0.999996 (TeX Live 2024/Arch Linux) (preloaded format=xelatex)

“编译器”应该可以正确处理这些文件。由于可以使用 pdflatex 加载，这意味着问题出在 xelatex 上。使用 pdflatex 只是为了看看它是否能编译文档。

在尝试了@David Carlisle 和@Ulrike Fischer 的建议后，我成功编译了它，并且运行良好。
我猜这不是问题的根源，但这是一个修复方法，因为之前它运行良好。
