说实话，我不太了解该bmpsize包的文档。
我在旧资料中找到了它，但没有提到为什么需要它。所以我的第一个问题是为什么需要它，因为似乎我编译的所有内容在没有它的情况下都可以正常工作。背景可能是在创建 dvi 文件吗？或者使用 htlatex 之类的东西？
第二个问题是为什么xelatex对于这个最小的例子来说编译会失败：
\documentclass{article}
\usepackage{bmpsize}
\begin{document}
Test
\end{document}
结果是：
his is XeTeX, Version 3.141592653-2.6-0.999994 (TeX Live 2022/TeX Live for SUSE Linux) (preloaded format=xelatex)
restricted \write18 enabled.

核心看起来是! Package bmpsize Error: You need pdfTeX 1.30.0 or newer.
这样的，我的 pdftex 确实更新很多，而且xelatex不依赖于pdftex，对吧？那么，这个提示是否意味着只有 pdflatex 才需要 bmpsize？那 呢lualatex？
我检查了xelatex的版本：

您几乎肯定不需要这个，graphicx（或者更确切地说它的使用extractbb）意味着大多数格式都可以处理。
但它应该可以工作。
提供的文件在 pdflatex 和 lualatex 中运行时没有错误，但在 xelatex 中却出现了一个虚假错误，因为pdftexmds无法定义包装器\filedump
\documentclass{article}
\makeatletter
\def\pdf@filedump#1#2#3{\filedump offset#1 length#2{#3}}
\makeatother
\usepackage{bmpsize}
\begin{document}
test
\end{document}
运行无错误
