显示子图的标签不可读

Question

当subfigures使用包添加时subcaption，包在 pdf 中生成的标签showlabels不可读。

包裹在包裹subcaption之前就已包含showlabels。我该如何纠正这个问题？

\usepackage{subcaption}
\usepackage{showlabels}

\begin{figure}
    \centering
    \begin{subfigure}[t]{0.48\linewidth}
        \includegraphics[width=1\linewidth]{plots/membrane/error_H1_rel_1d_100_11_11.pdf}
        \caption{Full RBs}
        \label{fig:membrane_recon_error_full_RB}
    \end{subfigure}
    \begin{subfigure}[t]{0.48\linewidth}
        \includegraphics[width=1\linewidth]{plots/membrane/error_H1_rel_1d_100_11_7.pdf}
        \caption{Full primal RB and truncated dual RB}
        \label{fig:membrane_recon_error_truncated_RB}
    \end{subfigure}
    \caption{Reconstruction error for points in and outside training set}
    \label{fig:membrane_recon_error}
\end{figure}

这将创建一个新的环境queuelabels，以防止showlabel在其中重叠标签。它使用url和marginnote包来格式化和打印标签。

注意：标签需要运行两次才能显示。

\documentclass{article}
\usepackage{subcaption}
\usepackage{marginnote}
\usepackage{url}
\usepackage{graphicx}

\let\normallabel=\label
\usepackage{showlabels}

\newsavebox{\labelbox}
\newenvironment{queuelabels}{\def\label##1{\normallabel{##1}%
  \global\setbox\labelbox=\vbox{%
    \hsize=\marginparwidth\raggedright
    \ifvoid\labelbox\else \unvbox\labelbox\vskip\baselineskip\fi
    \url{##1}}}}%
 {\dimen0=\ht\labelbox
  \marginnote{\unvbox\labelbox}[-\dimen0]}

\begin{document}

\begin{figure}
    \begin{queuelabels}
    \centering
    \begin{subfigure}[t]{0.48\linewidth}
        \includegraphics[width=1\linewidth]{example-image-a}
        \caption{Full RBs}
        \label{fig:membrane_recon_error_full_RB}
    \end{subfigure}
    \begin{subfigure}[t]{0.48\linewidth}
        \includegraphics[width=1\linewidth]{example-image-b}
        \caption{Full primal RB and truncated dual RB}
        \label{fig:membrane_recon_error_truncated_RB}
    \end{subfigure}
    \caption{Reconstruction error for points in and outside training set}
    \label{fig:membrane_recon_error}
    \end{queuelabels}
\end{figure}

\end{document}
