如何在子图乳胶环境的图形之间留出空间？

Question

我正在使用\ begin {subfigure} ... \ end {subfigure}命令并排插入三张图片。但是我想知道如何在此之间留出空间，因为它们彼此之间太近了。

\begin{figure}
    \begin{subfigure}
       here's the first image
    \end{subfigure}
    \begin{subfigure}
       here's the second image
    \end{subfigure}
    \begin{subfigure}
       here's the third image
    \end{subfigure}
\end{figure}

Answer 1

我建议使用subcaption并在图像之间添加一些\hspace：

\documentclass{article}

\usepackage{subcaption,graphicx}

\begin{document}

\begin{figure}
  \centering
  \begin{subfigure}{.3\linewidth}
    \centering
    \includegraphics[width = \linewidth]{example-image-a}
    \caption{First image}
  \end{subfigure}%
  \hspace{1em}% Space between image A and B
  \begin{subfigure}{.3\linewidth}
    \centering
    \includegraphics[width = \linewidth]{example-image-b}
    \caption{Second image}
  \end{subfigure}%
  \hspace{2em}% Space between image B and C
  \begin{subfigure}{.3\linewidth}
    \centering
    \includegraphics[width = \linewidth]{example-image-c}
    \caption{Third image}
  \end{subfigure}
  \caption{A number of images}
\end{figure}

\end{document}
