如何在整个文档上创建一条水平线？

Question

如何在整个文档的中间位置创建一条水平线？我希望这条线位于之前创建和放置的所有其他对象上方，以获得用水平线将整个文档切成两半的效果。有没有简单的方法可以添加它？

适应此解决方案，如果该线应与文本重叠。

\documentclass{article}
\usepackage{lipsum} % dummy text
\usepackage{tikz}
\usepackage{eso-pic}

\AddToShipoutPicture{%
    \begin{tikzpicture}[overlay,remember picture]
        \draw[line width=1pt,red]
              (current page.east) -- (current page.west);
    \end{tikzpicture}%
}

\begin{document}
 \lipsum 
\end{document}

如果你改变锚点，你可以轻松获得其他线条。例如(current page.south east) -- (current page.north west);

或者另一种规则。

(current page.west)       -- (current page.north) 
(current page.south west) -- (current page.north east)
(current page.south)      -- (current page.east)      ;
