垂直堆叠浮动

Question

我如何将三个浮点数垂直堆叠在一起，使得每个图的高度大约为页面文本高度的三分之一？（即它们都适合，包括标题和子标题）。我不在乎浮点数的宽度，只要比例适合线宽即可。

我更喜欢使用 subcaption 包。

感谢任何支持，

Answer 1

\documentclass[a4paper]{article}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}
\begin{figure}[htbp]
\centering
\subcaptionbox{some caption}[\textwidth]{\includegraphics[height=.3\textheight]{example-image-a}}
\subcaptionbox{some caption}[\textwidth]{\includegraphics[height=.3\textheight]{example-image-b}}
\subcaptionbox{some caption}[\textwidth]{\includegraphics[height=.3\textheight]{example-image-c}}
\caption{This is the main caption}
\end{figure}

\end{document}

Answer 2

通过这种stackengine方法，您可以控制从图像底部到子标题顶部的间隙（当前为1.1\baselineskip）以及从标题底部到下方图像顶部的间隙（当前为8pt）。

\documentclass{article}
\usepackage[usestackEOL]{stackengine}
\setstackgap{S}{8pt}
\setstackgap{L}{1.1\baselineskip}
\usepackage{graphicx}
\begin{document}
\begin{figure}[p]
\centering\Shortstack
{
\def\stacktype{L}
\stackunder{\includegraphics[height=.27\textheight]{example-image-a}}
           {(a) This is subcaption A}
\\
\def\stacktype{L}
\stackunder{\includegraphics[height=.27\textheight]{example-image-a}}
           {(b) This is subcaption B}
\\
\def\stacktype{L}
\stackunder{\includegraphics[height=.27\textheight]{example-image-a}}
           {(c) This is subcaption C}
}
\caption{This is the figure caption}
\end{figure}
\end{document}
