使用 tabularx 和 subfloats 对齐图形

Question

我想要做的是在tabularx和subfloats环境中对齐图形。

基本上，我想使用 5 个图形来显示一个流程/工作流，其中 1-3 个“连接”和 4+5。

这是我的代码：我尝试了两种不同的方法，但都不太一致：

\documentclass{report}
\usepackage{pifont}
\usepackage[svgnames, x11names]{xcolor}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subfig}
\usepackage{tabularx}

\newcommand\bigleftArrow{\color{Tomato2}\rotatebox[origin=c]{180}{\scalebox{2.4}[3.6]{\ding{225}}}}
\newcommand\bigrightArrow{\color{Tomato2}\rotatebox[origin=c]{0}{\scalebox{2.4}[3.6]{\ding{225}}}}

\newcolumntype{C}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}

\begin{document}

\begin{figure} [h]
\begin{tabularx}{\textwidth}{@{}*{5}{>{\centering\arraybackslash}X}@{}}
  \subfloat[text 1]{
     \includegraphics[width=0.28\textwidth]
     {example-image-a}}
      &
      \bigleftArrow
      &
  \subfloat[text 2]{
     \includegraphics[width=0.28\textwidth]
     {example-image-b}}
      &
      \bigleftArrow
      &
  \subfloat[text 3 is longer as  the others text text text text text]{
     \includegraphics[width=0.28\textwidth]
     {example-image-c}}
     \\
  \subfloat[text 4]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}
       &
       &
       \bigrightArrow
       &
       &
  \subfloat[text 5]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}


\end{tabularx}
  \captionof{figure}[]{long text 1}
  \label{fig:merge}
\end{figure}

     {example-image}}
      &
      &
      \bigrightArrow
      &
      &
  \subfloat[text5]{
     \includegraphics[width=0.28\textwidth]
     {example-image}}


\end{tabularx} 
  \captionof{figure}[]{long text 2}

问题是，我想让垂直和水平箭头在每一行中居中。但这是我的结果：

---

它看起来应该是这样的：

有人可以给我一些关于对齐的提示吗（或者如果需要的话可以用其他方法来解决这个问题）？

Answer 1

您可以使用一些组合\makebox。

该\vcenterobject宏垂直移动其参数，使得高度等于深度。

该\makebox[0pt]{...}命令会创建一个位于“列”之间的零宽度框。

请注意，由于行尾未受保护，因此存在多个虚假空格。我还简化了箭头的定义。

\documentclass{report}
\usepackage{pifont}
\usepackage[svgnames, x11names]{xcolor}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subfig}

\newcommand\bigleftArrow{%
  \scalebox{-2.4}[3.6]{%
    \color{Tomato2}\ding{225}%
  }%
}
\newcommand\bigrightArrow{%
  \scalebox{2.4}[3.6]{%
    \color{Tomato2}\ding{225}%
  }%
}

\newcommand{\vcenterobject}[1]{%
  \begin{tabular}{@{}c@{}}#1\end{tabular}%
}

Answer 2

从 TeX 原始角度来看，您需要做这样的事情：

\def\vhb#1{\vtop{\hbox{#1}}}
\def\rb#1{\raise.9cm\hbox{#1}}

\begin{figure}[h]
\hbox to\hsize{%
  \vhb{\subfloat[text 1]{\includegraphics[width=0.28\textwidth]{example-image-a}}}%
  \hss \rb\bigleftArrow \hss
  \vhb{\subfloat[text 2]{\includegraphics[width=0.28\textwidth]{example-image-b}}}%
  \hss \rb\bigleftArrow \hss
  \vhb{\subfloat[text 3 is longer as  the others text text text text text]{
     \includegraphics[width=0.28\textwidth]{example-image-c}}}%
}
\hbox to\hsize{%
  \vhb{\subfloat[text 4]{\includegraphics[width=0.28\textwidth]{example-image}}}%
  \hss \rb\bigrightArrow \hss
  \vhb{\subfloat[text 5]{\includegraphics[width=0.28\textwidth]{example-image}}}%
}
\end{figure}
