如何在LaTeX中使图片变宽？

Question

我试着在一个大数字上画几幅画。然而，它们被放在非常近的地方。我需要在它们之间增加更多的空间(在水平和垂直的图片之间)。

代码：

\documentclass{article}

\usepackage{subcaption}
\usepackage{graphicx}

\begin{document}
\begin{figure}[h]
    \centering
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{figs/solutions/transaction_solution.png}
        \caption{Transaction level isolation}
        \label{fig:subim1}
    \end{subfigure}
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{figs/solutions/locking_solution.png}
        \caption{Record locking}
        \label{fig:subim2}
    \end{subfigure}
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{figs/solutions/cache_solution.png}
        \caption{Shared cache synchronization}
        \label{fig:subim3}
    \end{subfigure}
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{figs/solutions/message_broker_solution.png}
        \caption{Message broker sequentializing}
        \label{fig:subim4}
    \end{subfigure}
    \captionsetup{justification=centering,margin=1cm}
    \caption{\label{fig:knng} Existing synchronization approaches for multiple server applications}
\end{figure}
\end{document}

Answer 1

根据您想要的内容，您可以将图像粘在两边的边缘，中间有一些空间，或者将它们均匀地分布在页面上。在这两种情况下，使用中间的\hspace{\hfill}作为填充。前一种情况不需要其他任何东西。但是，在后一种情况下，您还需要在两边添加\hspace{\hfill}；这是示例中的情况。

我也使用自定义长度，因为图像似乎具有相同的大小，所以您不需要在每次更改时重复自己。

不幸的是，这次我不能发照片了。

\documentclass[12pt]{article}
\usepackage{graphicx}
\usepackage{subcaption}
\captionsetup{format=hang}   % <--- added
\usepackage{showframe}       % Draws frames around a page
    \renewcommand*{\ShowFrameLinethickness}{0.2pt}
    \renewcommand*{\ShowFrameColor}{\color{blue}}
\newlength\sfigwidth


\begin{document}
\setlength\sfigwidth{0.37\textwidth}

\begin{figure}[h]
  \hspace{\fill}%   % <--- cases uniform redistribution
  \begin{subfigure}[t]{\sfigwidth}

Answer 2

在子图之间使用\hspace和\vspace。

\documentclass{article}

\usepackage{subcaption}
\usepackage{graphicx}

\begin{document}

\begin{figure}[h]
    \centering
    \begin{subfigure}{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{placeholder_1.png}
        \caption{Transaction level isolation}
        \label{fig:subim1}
    \end{subfigure}%
    \hspace{3em}%
    \vspace{1em}
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{placeholder_1.png}
        \caption{Record locking}
        \label{fig:subim2}
    \end{subfigure}%
    \vspace{1em}
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{placeholder_1.png}
        \caption{Shared cache synchronization}
        \label{fig:subim3}
    \end{subfigure}%
    \hspace{3em}%
    \begin{subfigure}[b]{0.4\textwidth}
        \centering
        \includegraphics[scale=0.6]{placeholder_1.png}
        \caption{Message broker sequentializing}
        \label{fig:subim4}
    \end{subfigure}
    \captionsetup{justification=centering,margin=1cm}
    \caption{\label{fig:knng} Existing synchronization approaches for multiple server applications}
\end{figure}

\end{document}
