用Tikz制作精美的边框装饰

代码设计如下：

\documentclass{article}
\usepackage[%
  margin=4cm
  %,showframe% to show the page layout
]{geometry}
\usepackage[object=vectorian]{pgfornament}

\newcommand\om{5mm}% ornament margin
\newcommand\ow{5cm}% ornament width
\newcommand\ols{5.5mm}% ornament line shift
\newcommand\on{63}% ornament number
\colorlet{bordercolor}{purple}
\tikzset{
ol/.style={line width=1mm,dotted}% style for the lines
}

% define the border and save it in a box
\newsavebox\border
\sbox\border{%
  \tikz[color=bordercolor]{
    \useasboundingbox(0,0)rectangle(\paperwidth,-\paperheight);
    \foreach[count=\i]\a/\p/\s in {%
      north west/{\om,-\om}/none,
      north east/{{\paperwidth-\om},-\om}/v,
      south east/{{\paperwidth-\om},{-\paperheight+\om}}/c,%
      south west/{\om,{-\paperheight+\om}}/h%
      }\node[anchor=\a](n\i) at (\p){\pgfornament[width=\ow,symmetry=\s]{\on}};
    \begin{scope}[ol]
      \draw([yshift=-\ols]n1.north east)--([yshift=-\ols]n2.north west);
      \draw([xshift=-\ols]n2.south east)--([xshift=-\ols]n3.north east);
      \draw([yshift=\ols]n3.south west)--([yshift=\ols]n4.south east);
      \draw([xshift=\ols]n4.north west)--([xshift=\ols]n1.south west);
    \end{scope}
  }%
}

\usepackage[manualmark]{scrlayer-scrpage}
\clearpairofpagestyles
\addtokomafont{pagehead}{\color{blue!50!green!80!black}\large}
\chead*{The current page style is \toplevelpagestyle{} \ifstr{\toplevelpagestyle}{\currentpagestyle}{}{as alias for \currentpagestyle}.}
\cfoot*{\pagemark}

% define a switch to enable and disable the border
\newif\ifBorder
% define a new layer
\DeclareNewLayer[{%
    background,
    page,
    contents={\ifBorder\usebox\border\fi}
  }]{border.bg}
% add the border layer to all layer page styles (scrheadings, plain, empty, ...) ...
\AddLayersAtBeginOfPageStyle{@everystyle@}{border.bg}
% but no border on empty pages
\AddToLayerPageStyleOptions{empty}{oninit=\Borderfalse}

\usepackage{blindtext}% dummy text
\begin{document}
\Bordertrue
\Blindtext
\clearpage
\pagestyle{empty}
\Blindtext[10]
\clearpage
\pagestyle{plain}
\Blindtext
\end{document}
