通过“typearea”查看横向页面的几何形状

Question

我landscape pages用这个包在我的文章里插入了一些typearea。然后我发现text body横向页面的两边空白很小，浪费了太多的横向边距空间。请看附图。

那么，如何放大横向页面的文本主体（宽度和高度）？以及如何分别调整所有页面尺寸（headheight、bottom、top等hmargin）。

梅威瑟：

\documentclass{article}
\usepackage{typearea}
\usepackage{geometry,layout}
\geometry{showframe}
\begin{document}
\section{This is my Portrait Page}
\clearpage
\KOMAoptions{paper=landscape,pagesize}
\recalctypearea
\section{This is my Landscape Page}
Text in my landscape section\footnote{Footnote in Landscape}
\clearpage
Text in my landscape
\clearpage
\KOMAoptions{paper=portrait,pagesize}
\recalctypearea
\section{This is again Portrait Page}
\end{document}

Answer 1

不含包装的建议geometry：

\documentclass{article}
\usepackage{typearea}
\usepackage{showframe}

\AtBeginDocument{%
  \storeareas\normalpapersize
}
\BeforeRestoreareas{\cleardoublepage}

\newcommand*\uselandscape{%
  \cleardoublepage
  \KOMAoptions{paper=landscape}%
  \recalctypearea
  \areaset{1.6\textwidth}{1.6\textheight}% adjust here: \areaset{<text body width>}{<text body height>}
}

\begin{document}
\section{This is my Portrait Page}

\uselandscape
\section{This is my Landscape Page}
Text in my landscape section\footnote{Footnote in Landscape}
\clearpage
Text in my landscape

\normalpapersize
\section{This is again Portrait Page}
\end{document}

建议使用包geometry来调整边距：

\documentclass{article}
\usepackage[usegeometry]{typearea}
\usepackage[showframe]{geometry}
\newcommand*\useportrait{%
  \cleardoublepage
  \KOMAoptions{paper=portrait,DIV=current}%
  \newgeometry{hmargin=2cm,top=3cm,bottom=4cm}%
}
\newcommand*\uselandscape{%
  \cleardoublepage
  \KOMAoptions{paper=landscape,DIV=current}%
  \newgeometry{vmargin=2cm,left=4cm,right=3cm}%
}
\AtBeginDocument{\useportrait}
\begin{document}
\section{This is my Portrait Page}

\uselandscape
\section{This is my Landscape Page}
Text in my landscape section\footnote{Footnote in Landscape}
\clearpage
Text in my landscape

\useportrait
\section{This is again Portrait Page}
\end{document}
