在背景中重复水印

Question

如何以倾斜的方式在标题页的背景中重复插入水印。以下是 MWE：

\documentclass{article}
\usepackage{background}
\usepackage{lipsum}

\backgroundsetup{%
  scale=1,       
  angle=0,         
  opacity=.6,    
  color =black,  
  contents={\begin{tikzpicture}[remember picture,overlay]
        \node at ([yshift=11pt,xshift=5pt]current page.center) {\includegraphics[width=5cm]{example-image-a}};    
    \end{tikzpicture}}
}
\begin{document}
\lipsum[1-50]
\end{document}

我希望实现这一点的代码：

\documentclass[12pt]{book}
\usepackage{graphicx}
\usepackage{background}

\newlength{\drop}

\backgroundsetup{%
  scale=1,       %% change accordingly
  angle=0,       %% change accordingly
  opacity=.6,    %% change accordingly
  contents={\begin{tikzpicture}[remember picture,overlay]
        \node at ([yshift=11pt,xshift=5pt]current page.center) {\includegraphics[width=5cm]{logo}};    %% yshift and xshift for example only
    \end{tikzpicture}}
}

\begin{document}
\begin{titlepage}
\drop=0.1\textheight
\centering
\vspace*{\baselineskip}
\rule{\textwidth}{1.6pt}\vspace*{-\baselineskip}\vspace*{2pt}
\rule{\textwidth}{0.4pt}\\[\baselineskip]
{\LARGE\bfseries JAVA\\[0.3\baselineskip] {\Large Core Concepts}}\\[0.2\baselineskip]
    \rule{\textwidth}{0.4pt}\vspace*{-\baselineskip}\vspace{3.2pt}
    \rule{\textwidth}{1.6pt}\\[\baselineskip]
    {\Large\bfseries BY \\[2mm]SUBHAM SONI}\\[\baselineskip]
    \includegraphics{logo}\\[1.2cm]
    {\Large\scshape May 27, 2014}
\end{titlepage}
\end{document}

使用选项加载background包pages=some，然后\BgThispage用于标题页；使用minipage用于内容和足够数量的图像副本，您将获得所需的结果：

\documentclass[12pt]{book}
\usepackage{graphicx}
\usepackage[pages=some]{background}
\usepackage{lipsum}

\newcommand\DupImage{%
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill%  
     \includegraphics[width=5cm]{logo}\hfill% 
}

\newlength{\drop}

\backgroundsetup{%
  scale=1,       %% change accordingly
  angle=45,       %% change accordingly
  opacity=.3,    %% change accordingly
  contents={%
     \begin{minipage}{1.5\paperheight}
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage\\[2ex]
     \DupImage
     \end{minipage}% 
   }  
}

\begin{document}

\begin{titlepage}
\drop=0.1\textheight
\BgThispage
\centering
\vspace*{\baselineskip}
\rule{\textwidth}{1.6pt}\vspace*{-\baselineskip}\vspace*{2pt}
\rule{\textwidth}{0.4pt}\\[\baselineskip]
{\LARGE\bfseries JAVA\\[0.3\baselineskip] {\Large Core Concepts}}\\[0.2\baselineskip]
    \rule{\textwidth}{0.4pt}\vspace*{-\baselineskip}\vspace{3.2pt}
    \rule{\textwidth}{1.6pt}\\[\baselineskip]
    {\Large\bfseries BY \\[2mm]SUBHAM SONI}\\[\baselineskip]
    \includegraphics{logo}\\[1.2cm]
    {\Large\scshape May 27, 2014}
\end{titlepage}
\lipsum[1-10]
\end{document}
