更改页面格式后分页问题

Question

我遇到了以下问题。我正在写论文，需要将页面格式从 A4 改为 A3 以包含图表。之后，我想恢复到原始格式。

但是格式更改后，第一页末尾总是会出现不想要的分页符。我不知道如何消除它，也不知道为什么会出现这个问题。

希望您能帮助我。提前谢谢您。

这就是我的意思：

Answer 1

您的 MWE 无法编译。您看到软件包的警告了吗typearea？

包 typearea 警告：\typearea 在组级别 3 中使用。在任何组（例如环境、数学模式、框等）内使用 \typearea 可能会导致许多排版问题。您应该将命令 \typearea 移到输入行 130 上的所有组之外。

您可以在固定位置的所有组外插入图片。要保存页面布局，请使用类似\storeareas\savedlayout。然后，您可以使用 恢复页面布局\savedlayout。

\documentclass[12pt,
    parskip=half-% do not set parskip manually
]{scrreprt}
% page layout
\usepackage[left=50mm,right=20mm,top=20mm,bottom=20mm]{geometry}
% page header layout
\usepackage[automark]{scrlayer-scrpage}
\clearpairofpagestyles
\ihead{\headmark}
\ohead{\pagemark}
\cfoot{to show the footer position}
\renewcommand{\partpagestyle}{empty}
\renewcommand{\chapterpagestyle}{scrheadings}
\usepackage{graphicx}
\usepackage{lipsum}
\begin{document}
\lipsum[7-15]
Figure \ref{Big picture}.

\clearpage
\storeareas\savedlayout
\KOMAoptions{paper=a3, paper=landscape, DIV=25}
\includegraphics[height=.95\textheight,width=\linewidth]{example-image}
\captionof{figure}{Big picture}
\label{Big picture}
\clearpage
\savedlayout

\lipsum[1-15]
\end{document}

另一种可能性是使用虚拟页面和虚拟标题作为文档中的占位符：

\documentclass[12pt,
parskip=half-% do not set parskip manually
]{scrreprt}
 %page layout
\usepackage[left=50mm,right=20mm,top=20mm,bottom=20mm]{geometry}
 %page header layout
\usepackage[automark]{scrlayer-scrpage}
\clearpairofpagestyles
\ihead{\headmark}
\ohead{\pagemark}
\cfoot{to show the footer position}
\renewcommand{\partpagestyle}{empty}
\renewcommand{\chapterpagestyle}{scrheadings}
\usepackage{afterpage}
\usepackage{lipsum}
\begin{document}
\captionof{figure}{picture}
\captionof{figure}{picture}
\captionof{figure}{picture}
\lipsum[7-15]
Figure \ref{Big picture}

\afterpage{
\clearpage
This page should be replaced in a second step.
\captionof{figure}{Big picture}\label{Big picture}
\clearpage
}

\lipsum[1-15]
\end{document}

第二步，替换占位符：

\documentclass{scrreprt}
\usepackage{pdfpages}
\begin{document}
\includepdf[pages=1-2]{mydoc.pdf}% pages before dummy page
%
\storeareas\savedlayout
\clearpage
\setcounter{figure}{3}% set the figure number
\KOMAoptions{paper=a3,paper=landscape,DIV=20}
\centering
\includegraphics[height=.95\textheight,width=\linewidth]{example-image}
\captionof{figure}{Big picture}
\clearpage
\savedlayout
%
\includepdf[pages=4-]{mydoc.pdf}% pages after the dummy page
\end{document}
