并排图片：标题和尺寸问题

Question

我对 Latex 还不太熟悉，在并排放置图形时遇到了一些问题。我希望将第一幅图像移到文本左侧一点，将第二幅图像移到文本右侧一点，这样我就可以将它们放大而不会重叠。此外，我希望子标题相对于图形居中。所以我想问你：

• 我的代码有什么问题？
• 有没有更好的方法来实现我想要做的事情？
• 如何扩大文本和图像之间的空间？

我附上我所能做的事情。

\documentclass[a4paper,12pt]{report}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}
\setlength{\parindent}{10pt}
\usepackage{lipsum} 
\usepackage{ae}
\usepackage{mwe}

\begin{document}

\lipsum[1-2]

\begin{figure}[h]
\centering 
\begin{subfigure}[t]{0.499\textwidth}%
\hspace{-2.5 cm}%
\includegraphics[scale=0.4]{{example-image-a}}%
\subcaption{Nel mezzo del cammin di nostra vita mi ritrovai per una selva oscura}%
\end{subfigure}%
\hfill%
\begin{subfigure}[t]{0.499\textwidth}%
\includegraphics[scale=0.4]{{example-image-a}}%
\subcaption{Quel ramo del lago di Como, che volge a mezzogiorno, tra due catene non interrotte di monti}%
\hspace{-2.5 cm}%
\end{subfigure}
\caption{Caption}
\end{figure}

\lipsum[3-4]

\end{document}

多谢！

Answer 1

如果您希望图像宽度大于文本宽度，则changepage该包可以帮助您：

\documentclass[a4paper,12pt]{article}
\usepackage[T1]{fontenc}
\usepackage{ae}
\usepackage[greek,english]{babel}
\usepackage{graphicx}
\usepackage[font=small, labelfont=bf]{caption}
\usepackage{subcaption}
\usepackage[strict]{changepage}
\setlength{\parindent}{10pt}

\usepackage{lipsum}

\begin{document}
\lipsum[1]
    \begin{figure}[ht]
\begin{adjustwidth}{-22mm}{-22mm}
\parbox{\linewidth}{% I don't know why is needed that caption has expected width
    \setkeys{Gin}{width=\linewidth}
\begin{subfigure}[t]{0.48\linewidth}%
\includegraphics{example-image-a}%
\subcaption{Nel mezzo del cammin di nostra vita mi ritrovai per una selva oscura}%
\end{subfigure}%
    \hfill%
\begin{subfigure}[t]{0.48\linewidth}%
\includegraphics{example-image-b}%
\subcaption{Quel ramo del lago di Como, che volge a mezzogiorno, tra due catene non interrotte di monti}%
\end{subfigure}

\caption{Caption}
}% end of parbox
\end{adjustwidth}
\end{figure}

\lipsum[2-3]
\end{document}

Answer 2

如果要防止图像之间重叠，最好使用选项，width=\linewidth而不是间接的选项scale=0.4。（我会将宽度设置为0.48\textwidth，而不是0.499\textwidth...）通过这种调整，也没有必要使用\hspace*指令。

\documentclass[a4paper,12pt]{report}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english,italian]{babel}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

\setlength{\parindent}{10pt}
\usepackage{lipsum} 

\begin{document}
\lipsum[1]

\begin{figure}[h]
\begin{subfigure}[t]{0.48\textwidth}
\includegraphics[width=\linewidth]{example-image-a}
\caption{Nel mezzo del cammin di nostra vita mi ritrovai per una selva oscura}
\end{subfigure}%
\hfill
\begin{subfigure}[t]{0.48\textwidth}
\includegraphics[width=\linewidth]{example-image-b}
\caption{Quel ramo del lago di Como, che volge a mezzogiorno, tra due catene non interrotte di monti}
\end{subfigure}

\caption{Caption} % overall caption
\end{figure}

\lipsum[3]
\end{document}

子图只是带有标题的迷你页面。不确定为什么我需要\struts \hfill。

\setlength{\parindent}{10pt}
\usepackage{lipsum} 
\usepackage{ae}
\usepackage{mwe}

\begin{document}

\lipsum[1-2]

\begin{figure}[h]
\hspace*{-2.5 cm}%
\begin{subfigure}[t]{\dimexpr 0.5\textwidth+2.5cm-0.5\columnsep}
\centering
\includegraphics[scale=0.4]{{example-image-a}}%
\caption{Nel mezzo del cammin di nostra vita mi ritrovai per una selva oscura}%
\end{subfigure}%
\strut\hfill\strut
\begin{subfigure}[t]{\dimexpr 0.5\textwidth+2.5cm-0.5\columnsep}
\centering
\includegraphics[scale=0.4]{{example-image-a}}%
\caption{Quel ramo del lago di Como, che volge a mezzogiorno, tra due catene non interrotte di monti}%
