在双列环境中将不同大小的图像与标题垂直对齐

Question

我试图让第二行中较小的图像与第一行中较大的图像居中对齐：（使用 MS Word）

我尝试了以下代码：

\begin{figure*}[h]
\centering
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4a.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4b.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4c.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4d.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4e.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=8em]{4f.png}}\\

\subcaptionbox{} [4em] {\includegraphics[width=4em]{4g.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=4em]{4h.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=4em]{4i.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=4em]{4j.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=4em]{4k.png}}\hfill
\subcaptionbox{} [4em] {\includegraphics[width=4em]{4l.png}}
        \caption {My caption}
\end{figure*}

得出：

但是，如您所见，我必须手动调整 hspace 值，以使每个较小的图像与其对应的较大图像居中对齐。我该怎么做？

Answer 1

而是使用subcaption包裹它允许您指定子图形块的宽度。以下是示例\subcaptionbox{<caption>}[<width>]{<stuff>}：

\documentclass{article}

\usepackage{subcaption,graphicx}

\begin{document}

\begin{figure}
  \centering
  \subcaptionbox{}[4em]{\includegraphics[width=4em,angle=90]{example-image-a}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em,angle=90]{example-image-b}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em,angle=90]{example-image-c}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em,angle=90]{example-image-b}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em,angle=90]{example-image-a}}

  \subcaptionbox{}[4em]{\includegraphics[width=4em]{example-image-a}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em]{example-image-b}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em]{example-image-c}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em]{example-image-b}}
  \subcaptionbox{}[4em]{\includegraphics[width=4em]{example-image-a}}

  \caption{My caption}
\end{figure}

\end{document}

如果你对（过时的）subfigure，您可以测量最宽元素的宽度，然后将其用作较窄图像的宽度：

\newlength{\widestimg}

\begin{figure}
  \centering
  \settowidth{\widestimg}{\includegraphics{4a.png}}% Measure width of widest image
  \subfigure[]{\includegraphics{4a.png}}
  \subfigure[]{\includegraphics{4b.png}}
  \subfigure[]{\includegraphics{4c.png}}
  \subfigure[]{\includegraphics{4d.png}}
  \subfigure[]{\includegraphics{4e.png}}
  \subfigure[]{\includegraphics{4f.png}}

  \subfigure[]{\makebox[\widestimg]{\includegraphics{4g.png}}}
  \subfigure[]{\makebox[\widestimg]{\includegraphics{4h.png}}}
  \subfigure[]{\makebox[\widestimg]{\includegraphics{4i.png}}}
  \subfigure[]{\makebox[\widestimg]{\includegraphics{4j.png}}}
  \subfigure[]{\makebox[\widestimg]{\includegraphics{4k.png}}}
  \subfigure[]{\makebox[\widestimg]{\includegraphics{4l.png}}}

  \caption{My caption}
\end{figure}
