减少子标题之间的索引区域空间

减少子标题之间的索引区域空间

我插入了两行图像,\subcaptionbox但它们之间的垂直空间仍然存在,该空间最初由第一列图像的索引占据。

我怎样才能减少这个区域的空间?

我的代码:

\begin{figure}[h!]
    \captionsetup[subfigure]{position=b}
    \centering
    \caption{my-images}
    \label{fig:images}

    \subcaptionbox*{
        \label{img-0}}
    {\includegraphics[width=2.2cm]{img-0.jpg}}\hspace{0.5em}
    \subcaptionbox*{
        \label{img-1}}
    {\includegraphics[width=2.2cm]{img-1.jpg}}\hspace{0.5em}
    \subcaptionbox*{
        \label{img-2}}
    {\includegraphics[width=2.2cm]{img-2.jpg}}

    \subcaptionbox{
        \label{img-10}}
    {\includegraphics[width=2.2cm]{img-0.jpg}}\hspace{0.5em}
    \subcaptionbox{
        \label{img-11}}
    {\includegraphics[width=2.2cm]{img-1.jpg}}\hspace{0.5em}
    \subcaptionbox{
        \label{img-12}}
    {\includegraphics[width=2.2cm]{img-2.jpg}}

\end{figure}

我会将每个子图的元素堆栈放在 中tabular。这样您就可以使用 轻松控制间隙\\[<len>]

在此处输入图片描述

\documentclass[draft]{article}

\usepackage{graphicx,subcaption}

\begin{document}

\begin{figure}[ht]
  \captionsetup[subfigure]{position=b}
  \centering
  \caption{my-images}\label{fig:images}

  \setlength{\tabcolsep}{0pt}% Remove column gap in tabular
  \subcaptionbox{\label{img-0}}{%
    \begin{tabular}{c}
      \includegraphics[width=2.2cm]{img-00.jpg} \\[.5\normalbaselineskip]
      \includegraphics[width=2.2cm]{img-10.jpg}
    \end{tabular}}%
  \hspace{0.5em}%
  \subcaptionbox{\label{img-1}}{%
    \begin{tabular}{c}
      \includegraphics[width=2.2cm]{img-01.jpg} \\[.5\normalbaselineskip]
      \includegraphics[width=2.2cm]{img-11.jpg}
    \end{tabular}}%
  \hspace{0.5em}%
  \subcaptionbox{\label{img-2}}{%
    \begin{tabular}{c}
      \includegraphics[width=2.2cm]{img-02.jpg} \\[.5\normalbaselineskip]
      \includegraphics[width=2.2cm]{img-12.jpg}
    \end{tabular}}%
\end{figure}

\end{document}

上述建议是基于 a\subcaptionbox*和 a\label看起来是多余的这一事实。但是,如果您确实希望保留这种布局,可以插入负垂直空间以减少两行之间的间隙:

\begin{figure}[ht]
  \captionsetup[subfigure]{position=b}
  \centering
  \caption{my-images}\label{fig:images}

  \subcaptionbox*{.}{..}%
  \hspace{0.5em}%
  \subcaptionbox*{.}{..}%
  \hspace{0.5em}%
  \subcaptionbox*{.}{..}%

  \vspace{-0.5\baselineskip}

  \subcaptionbox{\label{.}}{..}%
  \hspace{0.5em}%
  \subcaptionbox{\label{.}}{..}%
  \hspace{0.5em}%
  \subcaptionbox{\label{.}}{..}%  
\end{figure}
