图像的水平和垂直对齐

Question

我正在使用此处提供的 acm latex 期刊模板：http://www.acm.org/publications/authors/submissions

这遵循单列格式。现在我有 8 张图片，我想按照以下模式显示这些图片和标题：

我不知道如何使用子图或任何其他方式获取这种格式。

\documentclass[format=acmsmall, review=false, screen=true]{acmart}
\usepackage{subcaption}
\usepackage{array}
\usepackage{varwidth}
\usepackage{lipsum}
\begin{document}
\title[This is a Title]{This is a title}  
\maketitle

\section{Introduction}
\lipsum[2-4]

\begin{center}
\begin{minipage}{0.5\columnwidth}
\includegraphics[width=\linewidth]{pam}
\captionof{figure}{}
\end{minipage}
\end{center}

\begin{center}
\begin{minipage}{0.5\columnwidth}
\includegraphics[width=\linewidth]{jam}
\captionof{figure}{}
\end{minipage}
\end{center}

Answer 1

使用subcaption软件包，subfigure环境是一个环境，具有附加的处理和语句minipage能力。\caption\label

\documentclass[format=acmsmall, review=false, 
               screen=true, demo]{acmart}
\usepackage{subcaption}
\usepackage{array,varwidth,lipsum}
\begin{document}
\title{Chow, Dow, and Pow}  
\author{Mr. T and the A-Team}
\date{\today}
\maketitle

\section{Introduction}
\lipsum[2-4] % filler text

\begin{figure}[tp!]
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figa}
\caption{}
\end{subfigure}\hfill
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figb}
\caption{}
\end{subfigure}

\medskip
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figc}
\caption{}
\end{subfigure}\hfill
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figd}
\caption{}
\end{subfigure}

\medskip
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{fige}

\end{subfigure}\hfill
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figf}

\end{subfigure}

\medskip
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figg}

\end{subfigure}\hfill
\begin{subfigure}{0.475\textwidth}
\includegraphics[width=\linewidth]{figh}
\caption{}
\end{subfigure}

\caption{Overall figure caption}
\end{figure}

\lipsum[5-12] % more filler text
\end{document}

\documentclass[format=acmsmall, review=false,
               screen=true, demo]{acmart}
\usepackage{subfig}
\usepackage{array,varwidth,lipsum}

\begin{document}
\title{Chow, Dow, and Pow}
\author{Mr. T and the A-Team}
\date{\today}
\maketitle

\section{Introduction}
\lipsum[2-4] % filler text

\begin{figure}[tp!]
\subfloat[]{\includegraphics[width=0.46\linewidth]{figa}}%
    \hfill
\subfloat[]{\includegraphics[width=0.48\linewidth]{figb}}

\medskip
\subfloat[]{\includegraphics[width=0.48\linewidth]{figc}}%
    \hfill
\subfloat[]{\includegraphics[width=0.48\linewidth]{figd}}

\medskip
\subfloat[]{\includegraphics[width=0.48\linewidth]{fige}}%
    \hfill
\subfloat[]{\includegraphics[width=0.48\linewidth]{figf}}

\medskip
\subfloat[]{\includegraphics[width=0.48\linewidth]{figg}}%
    \hfill
\subfloat[]{\includegraphics[width=0.48\linewidth]{figh}}

\caption{Overall figure caption}
\end{figure}

\lipsum[5-12] % more filler text
\end{document}

编辑： 添加%用于终止左侧四幅图像的代码行（如建议 米科在下面的评论中）。

Answer 3

我按照以下方式制作了两幅图像：

\begin{center}
\begin{minipage}{0.5\textwidth}
\includegraphics[width=0.95\linewidth]{imgs/gmail_spam/spam_spam}
\captionof{figure}{}
\end{minipage}%
\begin{minipage}{0.5\textwidth}
\includegraphics[width=0.95\linewidth]{imgs/gmail_spam/spam_phishing}
\captionof{figure}{}
\end{minipage}
\end{center}

\begin{center}
\begin{minipage}{0.5\textwidth}
...

重复 4 次。这样就得到了所需的格式。

如果有其他解决方案，请告诉我。
