我很高兴使用 overpic，并使用以下 MWE（用任何 .pdf 文件替换 Annulus-PBma-essai.pdf）
\documentclass [12pt]{amsbook}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage[percent]{overpic}
\begin{document}
\begin{figure}[ht]
\center\begin{overpic}[width=10cm]{Annulus-PBma-essai.pdf}
\put (32,65) {$z_{0}$}
\put (52,44){$z_1$}
\end{overpic}
\end{figure}
\end{document}
直到新版 overpic 出现，似乎不再接受“width”选项。因此我收到一条错误消息。我是否遗漏了什么？如果没有，是否有办法在新版本中获得与“width”相同的效果。[抱歉，我无法重现错误消息（与 setkeyval 有关），因为我更新了办公室电脑，但没有更新家用电脑。]
以下是完整日志
