如何在横向页面（tikz）latex中绘制矩形框

Question

我在同一个 latex 文件上有两页文档，一个是纵向的，一个是横向的。我需要为这两页绘制一个矩形框，左边距为 3cm，右边距为 2cm，上边距为 2cm，下边距为 2cm。对于纵向页面，我使用与下面相同的代码，但横向页面无法正确绘制。我认为坐标发生了变化。

\documentclass{article}
\usepackage{tikz}
 \usepackage{pdflscape}
\usetikzlibrary{calc}
\usepackage[fontsize=14pt]{scrextend}%font mặc định
\usepackage[paperheight=21cm,paperwidth=29.7cm,right=2.6cm,left=3.5cm,top=2cm,bottom=2cm]{geometry}%font a4
\begin{document}

 \begin{tikzpicture}[overlay,remember picture]
\draw [line width=3pt]
   ($ (current page.north west)+ (3.0cm,-2.0cm) $)
    rectangle
   ($ (current page.south east) + (-2.0cm, 2.5cm) $);
\draw [line width=0.5pt]
   ($ (current page.north west) + (3.1cm,-2.1cm) $)
    rectangle
   ($ (current page.south east) + (-2.1cm,2.6cm) $);
\end{tikzpicture}

\newpage

\begin{landscape}
 \begin{tikzpicture}[overlay,remember picture]
\draw [line width=3pt]
   ($ (current page.north west)+ (3.0cm,-2.0cm) $)
    rectangle
   ($ (current page.south east) + (-2.0cm, 2.5cm) $);
\draw [line width=0.5pt]
   ($ (current page.north west) + (3.1cm,-2.1cm) $)
    rectangle
   ($ (current page.south east) + (-2.1cm,2.6cm) $);
\end{tikzpicture}
\end{landscape}
\end{document}

Answer 1

该pdflscape包在横向坐标方面存在问题，但该typearea包工作正常。请注意切换方向时必须添加的两行：

\KOMAoptions{paper=portrait,pagesize}
\recalctypearea
