如何在双面文档中翻转边距水印

我有一个问题，我不知道该如何解决。我希望每次翻页时背景都会翻转。这样，成对的页面将在左侧有背景边距，而受损的页面将在右侧有背景边距照片。我希望我说清楚了。

\usepackage{background} %see the background doc for more info

\backgroundsetup{%  
  scale=1,       
  angle=0,       
  opacity=.7,    
  color =black,  
  contents={\begin{tikzpicture}[remember picture,overlay]
    \node at ([yshift=0cm,xshift=-9.7cm]current page) {\includegraphics[scale=1.10]{Margin.png}};    
\end{tikzpicture}}  
}

包文档的示例 4 解释了如何实现这一点。其思路是使用条件测试（根据您的具体需求调整位置和内容）：

\documentclass{article}
\usepackage[contents={},opacity=1,scale=1]{background}
\usepackage{lipsum}

\AddEverypageHook{%
\ifodd\value{page}\relax%
\backgroundsetup{% settings for odd-numbered pages
  angle=90,
  position={1.35\textwidth,-0.5\textheight},%
  contents={\includegraphics[height=3cm]{example-image-a}}
  }%
\else
\backgroundsetup{% settings for even-numbered pages
  angle=270,
  position={0,-0.5\textheight},%
  contents={\includegraphics[height=3cm]{example-image-b}}
}%
\fi%
\BgMaterial}

\begin{document}
\lipsum[1-30]
\end{document}

要省略前几页的背景材料，可以使用另一个条件；例如

\documentclass{article}
\usepackage[contents={},opacity=1,scale=1]{background}
\usepackage{lipsum}

\AddEverypageHook{%
\ifnum\value{page}>3
\ifodd\value{page}\relax%
\backgroundsetup{% settings for odd-numbered pages
  angle=90,
  position={1.35\textwidth,-0.5\textheight},%
  contents={\includegraphics[height=3cm]{example-image-a}}
  }%
\else
\backgroundsetup{% settings for even-numbered pages
  angle=270,
  position={0,-0.5\textheight},%
  contents={\includegraphics[height=3cm]{example-image-b}}
}%
\fi%
\BgMaterial
\fi}

\begin{document}
\lipsum[1-30]
\end{document}
