如何让一个图形包含多组图像并且每组图像都有单独的名称？

Question

我有几张图片，我必须在它们下面放置它们的名称。此外，我还需要给出这些图片组的名称（例如，如下所示的“第一层”、“第二层”等）。我需要有如下图所示的内容。

重要的：在我的例子中，一组图像可能包含多行。我的意思是，“（a）第一层”可能包含多于 3 幅图像，因此可以是多行的一组图像。

Answer 1

两个选项：

1. tabular对每一层和包使用一些s subcaption：

   

   代码：

   \documentclass{article}
   \usepackage{subcaption}
   \usepackage{graphicx}
   
   \begin{document}
   
   \begin{figure}
   \begin{minipage}{\linewidth}
     \centering
     \begin{tabular}{ccc}
     \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b}
       & \includegraphics[width=.28\linewidth,height=1cm]{example-image-c} \\
     First image & Second image & Third image \\  
     \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b} \\
     Fourth image & Fifth image &
     \end{tabular}
     \subcaption{First layer}
     \end{minipage}\par\bigskip
     \begin{minipage}{\linewidth}
     \centering
     \begin{tabular}{ccc}
     \includegraphics[width=.28\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=.28\linewidth,height=1cm]{example-image-b}
       & \includegraphics[width=.28\linewidth,height=1cm]{example-image-c} \\
     First image & Second image & Third image \\  
     \end{tabular}
     \subcaption{Second layer}
     \end{minipage}
   \caption{a figure with some layers of subfigures each with its own name and each layer with a subcaption}
   \end{figure}
   
   \end{document}
   

   tabular上面我使用了具有三种类型列的标准c；如果图像下方的文本跨越多行，则可以使用tabularx包tabularx和居中X列，如下面的选项所示。

2. 由于 OP 正在使用subfig，subcaption因此无法使用该包；这里有一个使用与以前相同想法的方法，但使用tabularx和subfig包：

   \documentclass{article}
   \usepackage[caption=false]{subfig}
   \usepackage{graphicx}
   \usepackage{tabularx}
   
   \newcolumntype{Y}{>{\centering\arraybackslash}X}
   
   \begin{document}
   
   \begin{figure}
   \subfloat[First layer]{%
   \begin{minipage}{\linewidth}
     \centering
     \begin{tabularx}{\linewidth}{YYY}
     \includegraphics[width=\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=\linewidth,height=1cm]{example-image-b}
       & \includegraphics[width=\linewidth,height=1cm]{example-image-c} \\
     First image & Second image & Third image \\  
     \includegraphics[width=\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=\linewidth,height=1cm]{example-image-b} \\
     Fourth image & Fifth image &
     \end{tabularx}
     \end{minipage}}\par\medskip
   \subfloat[Second layer]{%
     \begin{minipage}{\linewidth}
     \centering
     \begin{tabularx}{\linewidth}{YYY}
     \includegraphics[width=\linewidth,height=1cm]{example-image-a}
       & \includegraphics[width=\linewidth,height=1cm]{example-image-b}
       & \includegraphics[width=\linewidth,height=1cm]{example-image-c} \\
     First image & Second image & Third image \\  
     \end{tabularx}
     \end{minipage}}
   \caption{a figure with some layers of subfigures each with its own name and each layer with a subcaption}
   \end{figure}
   
   \end{document}
   

   

Answer 2

您可以有多行，例如查看此示例经典论文：

begin{figure}[bth]
    \myfloatalign
    \subfloat[Asia personas duo.]
    {\includegraphics[width=.45\linewidth]{gfx/example_1}} \quad
    \subfloat[Pan ma signo.]
    {\label{fig:example-b}%
     \includegraphics[width=.45\linewidth]{gfx/example_2}} \\
    \subfloat[Methodicamente o uno.]
    {\includegraphics[width=.45\linewidth]{gfx/example_3}} \quad
    \subfloat[Titulo debitas.]
    {\includegraphics[width=.45\linewidth]{gfx/example_4}}
    \caption[Tu duo titulo debitas latente]{Tu duo titulo debitas
    latente.}\label{fig:example}
\end{figure}
