svmono：如何垂直居中图形？

Question

使用 svmono 类时，如何才能将图形垂直居中？我在论坛中找到的传统解决方案似乎不适用于此类。请注意，这不是为了实际提交给出版商，而是为了私人用途。

谢谢并问候，豪尔赫。

PS svmono 课程可以下载这里。

示例（已更新）：

\documentclass[graybox,envcountchap,vecarrow,twoside]{svmono}
\usepackage[paperheight=240mm,paperwidth=170mm,top=2.5cm,inner=2.5cm]{geometry}

\usepackage[caption=false,font=footnotesize]{subfig}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{floatrow}

\begin{document}

% Some text
\lipsum[1-5]

% A figure in an new page
\clearpage
\begin{figure}[p]   %doesn't work
%\begin{figure}[H]  %doesn't work
\centering
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-a}}

\vspace{1cm}
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-b}}
\caption{This figure should be centered vertically}
\end{figure}

% Some text in an new page
\clearpage
\lipsum[6-10]

\end{document}

Answer 1

这是一种不使用figure环境而是caption使用包的方法：

\documentclass[graybox,envcountchap,vecarrow,twoside]{article}
\usepackage[paperheight=240mm,paperwidth=170mm,top=2.5cm,inner=2.5cm]{geometry}

\usepackage[caption=false,font=footnotesize]{subfig}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{caption}

%This code makes thhe whole job of vertical centering the image
% #1 includegraphics options
% #2 image name
% #3 image caption
\newsavebox{\mysavebox}
\newlength{\myvspace}
\newcommand\addCenteredImage[3][]{%
\clearpage
\savebox\mysavebox{\vbox{\phantom{.}\par\includegraphics[#1]{#2}}}%
\setlength\myvspace{\dimexpr(\paperheight-\dimexpr(\ht\mysavebox+\dp\mysavebox))/4\relax}%
\phantom{.}\vspace{\myvspace}\par\usebox\mysavebox\captionof{figure}{#3}\clearpage%
}


\begin{document}

% Some text
\lipsum[1-5]

% A figure in an new page
\addCenteredImage[height=10cm,width=10cm]{example-image-a}{This figure should be centered vertically}

\lipsum[6-10]

\end{document}

据我所知，这是一种使用简单命令的方法。

输出是您所期望的图像。

页面浮动使用以下方式排版

\vspace*{\@fptop}

<material of the float>

\vspace*{\@fpbot}

该类svmono设置\@fptop为零，保留\@fpbot默认值0pt plus 1fil。

只需添加适当的设置。

\documentclass[graybox,envcountchap,vecarrow,twoside]{svmono}
\usepackage[paperheight=240mm,paperwidth=170mm,top=2.5cm,inner=2.5cm]{geometry}

\usepackage[caption=false,font=footnotesize]{subfig}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{floatrow}

\makeatletter
\setlength\@fptop{0pt plus 1fil} % <--- restore the values
\makeatother

\begin{document}

% Some text
\lipsum[1-5]

% A figure in an new page
\clearpage
\begin{figure}[p]   %doesn't work
%\begin{figure}[H]  %doesn't work
\centering
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-a}}

\vspace{1cm}
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-b}}
\caption{This figure should be centered vertically}
\end{figure}

% Some text in an new page
\clearpage
\lipsum[6-10]

\end{document}

\usepackage[caption=false,font=footnotesize]{subfig}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{floatrow}


\begin{document}

% Some text
\lipsum[1-5]

% A figure in an new page
\clearpage\null\vfil
\begin{figure}[h]
\centering
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-a}}

\vspace{1cm}
\sidesubfloat[]{\includegraphics[height=6cm,width=8cm]{example-image-b}}
\caption{This figure should be centered vertically}
\end{figure}

% Some text in an new page
\clearpage
