如何确保两个相邻的图形和标题水平对齐？

Question

图像不共享水平底线，使用时标题也不共享：

\centering
\begin{minipage}{.48\textwidth}
  \centering
  \includegraphics[width=\linewidth]{Figures/im1}
  \captionof{figure}{Long caption ..........................................................................................................................}
  \label{fig:im1}
\end{minipage}
\hfill
\begin{minipage}{.48\textwidth}
  \centering
  \includegraphics[width=\linewidth]{Figures/im2}
  \captionof{figure}{Long caption ...........................................................................................................................}
  \label{fig:im2}
\end{minipage}
\end{figure}

有什么方法可以使图像的底部和标题的顶部水平对齐？

Answer 1

该floatrow包非常简单：

\documentclass{article}
\usepackage[margin=2cm]{geometry}
\usepackage{erewhon}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{floatrow}

\begin{document}

\begin{figure}
\centering
\begin{floatrow}
\ffigbox[\FBwidth]{\caption{Meret Oppenheim – Schoolgirl’s Notebook}}{ \includegraphics[width=\linewidth]{cahier}}
\hfill
\ffigbox[\FBwidth]{\caption{Meret Oppenheim – My Nurse}}{\includegraphics[width=0.8\linewidth]{magouvernante}}
\end{floatrow}
\end{figure}

\end{document} 

Answer 2

\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\begin{document}

\begin{figure}
\centering
\begin{minipage}[b]{.48\textwidth}
  \includegraphics[width=\linewidth]{example-image}
\end{minipage}
\hfill
\begin{minipage}[b]{.48\textwidth}
  \includegraphics[width=\linewidth]{example-image-16x9}
\end{minipage}
\begin{minipage}[t]{.48\textwidth}
  \caption{Long caption long caption long caption long caption long caption long caption long caption long caption long caption long caption \label{fig:im1}}
\end{minipage}
\hfill
\begin{minipage}[t]{.48\textwidth}
  \caption{Long caption long caption long caption long caption long caption long caption \label{fig:im2}}
\end{minipage}
\end{figure}

\end{document}

Answer 3

两种方法——测量图形的宽度并将其保存在sbox——或者使用选项将其对齐minipages在底部[b]——两者的结果相同

选择savebox​

或minipages底部对齐，captionsetup = linewidth
