如何在 floatrow 包中进行子引用-hyperref？

我有一个使用 floatrow 包的子图环境，我想在我的段落中单独引用面板中的每个图，如下所示：

图（3a）和图（3b），但是当我调用命令时，它不知何故不起作用\subref。

我的完整代码：

\documentclass[12pt,reqno]{report}
\begin{document}

\usepackage{graphicx}

\usepackage{floatrow}
    \floatsetup[figure]{subcapbesideposition=top}
\usepackage{graphicx}
\usepackage[label font=bf, 
            labelformat=simple]{subfig}
\usepackage{caption}

    \begin{figure}[H]
    \renewcommand\thesubfigure{\Alph{subfigure}}
    \setlength{\labelsep}{2mm}
    \centering
\sidesubfloat[  \label{fig:mHCN2_dime}]%
{
\includegraphics[width=0.4\textwidth]{figs/Fig_edited_figure_A_in_panel.png}\label{fig:a}%
}
\hfill
\sidesubfloat[  \label{fig:non-swapped_mHCN2}]%
{
\includegraphics[width=0.4\textwidth]{figs/mHCN2_cAMP_hidden_rotated_90_non-swapped_packing.png}\label{fig:a}%
}

\caption{Structure of the channel tetramer in the ligand-free state, viewed parallel to the membrane (A) or from the extracellular side (B). Each subunit is shown in a different color. Gray bars represent approximate boundaries of the membrane bilayer.}

\label{fig:mHCN2}
  \end{figure}

\end{document}

这提供了subcaption的兼容版本\sidesubfloat。

棘手的是，标题（甚至\captiontext）总是会填满给定的空间，所以我们需要先通过伪造来测量所需的空间。

\documentclass[12pt]{report}
\usepackage{graphicx}
\usepackage{subcaption}

\newcommand{\sidesubfloat}[2][\empty]% #1 = caption and \label (optional}, #2 image
{\begin{subcaptiongroup}
  \refstepcounter{subfigure}% get width of caption
  \sbox0{(\thesubfigure)~#1~}% assumed format
  \addtocounter{subfigure}{-1}%
  \sbox1{#2}% get width of image
  \dimen0=\dimexpr \linewidth-\wd1\relax
  \ifdim\dimen0>\wd0
    \dimen0=\wd0
  \fi
  \setbox2=\vbox{\hsize=\dimen0\caption{#1}}%
  \raisebox{\dimexpr \abovecaptionskip+\ht1-\ht2}[\ht1]{\usebox2}#2
\end{subcaptiongroup}}

\begin{document}
    \begin{figure}[ht]
    \renewcommand\thesubfigure{\Alph{subfigure}}
    \setlength{\labelsep}{2mm}
    \centering
\sidesubfloat[  \label{fig:mHCN2_dime}]%
{
\includegraphics[width=0.4\textwidth]{example-image-a}\label{fig:a}%
}
\hfill
\sidesubfloat[  \label{fig:non-swapped_mHCN2}]%
{
\includegraphics[width=0.4\textwidth]{example-image-b}\label{fig:b}%
}

\caption{Structure of the channel tetramer in the ligand-free state, viewed parallel to the membrane (A) or from the extracellular side (B). Each subunit is shown in a different color. Gray bars represent approximate boundaries of the membrane bilayer.}

\label{fig:mHCN2}
  \end{figure}
  
\subref{fig:mHCN2_dime} \subref{fig:a}
\subref{fig:non-swapped_mHCN2} \subref{fig:b}

\ref{fig:mHCN2_dime} \ref{fig:a}
\ref{fig:non-swapped_mHCN2} \ref{fig:b}

\end{document}

使用\ref{fig:a} 和\ref{fig:b}（您的代码中缺失）。

A

\documentclass[12pt]{report}

\usepackage{floatrow}
\floatsetup[figure]{subcapbesideposition=top}
\usepackage{graphicx}
\usepackage[label font=bf, labelformat=simple]{subfig}
\usepackage{caption}

\begin{document}        

    \begin{figure}[H]
        \renewcommand\thesubfigure{\Alph{subfigure}}
        \setlength{\labelsep}{2mm}
        \centering
        \sidesubfloat[  \label{fig:mHCN2_dime}]%
        {
            \includegraphics[width=0.4\textwidth]{example-image-a}\label{fig:a}%
        }
        \hfill
        \sidesubfloat[  \label{fig:non-swapped_mHCN2}]%
        {
            \includegraphics[width=0.4\textwidth]{example-image-b}\label{fig:b}%
        }
        
        \caption{Structure of the channel tetramer in the ligand-free state, viewed parallel to the membrane (A) or from the extracellular side (B). Each subunit is shown in a different color. Gray bars represent approximate boundaries of the membrane bilayer.}
                    \label{fig:mHCN2}
    \end{figure}

See subfigures~\ref{fig:a}  and \ref{fig:b}.
