+% \begin{abstract}
+% \noindent This package allows the placement of background material on the pages of a
+% document. The user can control many aspects (i.e., contents, position, color, opacity) of the
+% background material that will be displayed.
+% \end{abstract}
+% \tableofcontents
+% \section{Introduction}
+% The \package{background} package relies on the \package{TikZ} and \package{everypar}
+% packages to provide a simple and flexible mechanism to include background material on all
+% (or on some of) the pages of a \LaTeX2e document.
+% \par\medskip
+% The implementation is quite simple and parallels the one of the \package{draftwatermark}
+% package by Sergio Callegari, but adds greater control over the background material attributes.
+% \par\medskip
+% The author will gladly receive suggestions, comments and bug reports.
+%
+% \section{User Interface}
+%
+% Loading this package (without any package options) in the preamble of a document in the
+% standard way:
+% \begin{center}
+% |\usepackage{background}|
+% \end{center}
+% activates a set of predefined options that will typeset the word "Draft" across every page of
+% your document (from the lower left corner to the upper right corner), using
+% \textcolor{red!45}{this color} and a huge font size.
+% \par\medskip
+% Of course, the package can be loaded using some of the options described in the next section;
+% for example:
+% \begin{center}
+% |\usepackage[some,bottom]{background}|
+% \end{center}
+%
+% \subsection{Package Options}
+% Table~\ref{tab:options} shows the available package options\MarNote{By
+% default, the package loads the options |all| and |center|.} and their meaning. Obviously, the
+% options |all| and |some| are mutually exclusive; the same remark applies to the group of options
+% |center|, |bottom|, and |top|.
+% \par\medskip
+% Take into account that using the |some| option will cause no background material to be displayed
+% at all and the user will have to issue the command |\BgThispage| for each page
+% in which he/she desires the background material to appear (see example \ref{exa:bgthispage}).
+%
+% \begin{table}[!ht]
+% \centering
+% \begin{tabular}{rp{6cm}}\toprule
+% Option & Meaning\\\toprule
+% |all| & The background material will be displayed in all the pages.\\
+% |some| & The background material will be displayed only in the pages for which the
+% |\BgThispage| command was used.\\
+% |center| & The background material will be displayed diagonally.\\
+% |bottom| & The background material will be displayed horizontally at the bottom of the page.\\
+% |top| & The background material will be displayed horizontally at the top of the page.
+% \\\bottomrule
+% \end{tabular}
+% \caption{The package options.}
+% \label{tab:options}
+% \end{table}
+%
+% \subsection{User Commands}
+% Since the commands used to modify attributes of the background material depend on the
+% |\node| construct offered by the \package{TikZ} package, we strongly encourage the reading
+% of Till Tantau's
+% \href{http://mirror.ctan.org/graphics/pgf/base/doc/generic/pgf/pgfmanual.pdf}%
+% {\emph{PGF/TikZ package manual}}.
+% \par\medskip
+% \DescribeMacro{\SetBgContents}
+% This command allows the user to change the material that will be used as background. The usage
+% is
+% \begin{center}
+% |\SetBgContents{|\meta{material}|}|
+ % \end{center}
+% where \meta{material} can be any text or an image (via the |\includegraphics| command
+% from the \package{graphicx} package) or even a graphic created, for example, with the
+% \package{TikZ} package.
+% \par\medskip
+% \DescribeMacro{\SetBgColor}
+% This command allows the user to change the color that will be used for the background material if % such material is text. The usage is
+% \begin{center}
+% |\SetBgContents{|\meta{color}|}|
+% \end{center}
+% where \meta{color} can be any color set by the \package{xcolor} package.
+% \par\medskip
+% \DescribeMacro{\SetBgAngle}
+% This command allows the user to change the angle that will be used for displaying the background % material. The usage is
+% \begin{center}
+% |\SetBgContents{|\meta{degrees}|}|
+% \end{center}
+% where \meta{degrees} can be any value between $-360$ and $360$.
+% \par\medskip
+% \DescribeMacro{\SetBgOpacity}
+% This command allows the user to change the transparency level for the background material. The % usage is
+% \begin{center}
+% |\SetBgOpacity{|\meta{value}|}|
+% \end{center}
+% where \meta{value} can be any number between $0$ (full transparency) and $1$ (no
+% transparency at all).
+% \par\medskip
+% \DescribeMacro{\SetBgScale}
+% This command allows the user to change the scaling factor that will be applied to the background
+% material. The usage is
+% \begin{center}
+% |\SetBgScale{|\meta{factor}|}|
+% \end{center}
+% where \meta{factor} can be any positive value.
+% \par\medskip
+% \par\medskip
+% \DescribeMacro{\SetBgPosition}
+% This command allows the user to define the position of the background
+% material. The usage is
+% \begin{center}
+% |\SetBgPosition{|\meta{position}|}|
+% \end{center}
+% where \meta{position} can be any valid\MarNote{Do not enclose \meta{position} inside
+% parentheses} position accepted by the |at| syntax for nodes placement (see the TikZ
+% manual). Some examples of valid positions are
+% \begin{center}
+% |\SetBgPosition{0,0}|\\
+% |\SetBgPosition{current page.north}|\\
+% |\SetBgPosition{5cm,7cm}|
+% \end{center}
+% \par\medskip
+% \DescribeMacro{\SetBgAnchor}
+% This command allows the user to set the anchor for the node placement. The usage is
+% \begin{center}
+% |\SetBgAnchor{|\meta{anchor name}|}|
+% \end{center}
+% Typical examples are:
+% \begin{center}
+% |\SetBgAnchor{north east}|\\
+% |\SetBgAnchor{west}|\\
+% \end{center}
+% \par\medskip
+% \DescribeMacro{\SetBgHshift}
+% \DescribeMacro{\SetBgVshift}
+% These two commands control the horizontal and vertical shifting of the node position.
+% \begin{center}
+% |\SetBgHshift{|\meta{value}|}|\\
+% |\SetBgVshift{|\meta{value}|}|
+% \end{center}
+% \par\medskip
+% The following two commands are designed to give the user control on whether the background
+% material should or should not appear on specific pages of the document.
+% \par\medskip
+% \DescribeMacro{\BgThispage}
+% This command permits to select particular pages in which the background material will
+% be displayed (see example \ref{exa:bgthispage}).
+%
+% \subsubsection{Experimental}
+% \DescribeMacro{\NoBgThispage}
+% This command will prevent the background material to be displayed in the page where it
+% \MarNote{Do not use this command in two column mode.}
+% was issued. Its implementation depends on the \package{afterpage} package,
+% so the corresponding precautions must be taken into account (see example
+% \ref{exa:nobgthispage}) .
+%
+% \section{Examples}
+% In the following examples, the \package{lipsum} package was used only to automatically
+% generate text.
+% \begin{exam}
+% This example shows how to display the background material only on the first two pages of
+% the document:
+% \end{exam}
+% |\documentclass{article}|\\
+% |\usepackage{background}|\\
+% |\usepackage{lipsum}|\\
+%
+% |\begin{document}|\\
+% |\lipsum[1-10]|\\
+% |\newpage\SetBgContents{}|\\
+% |\lipsum[1-30]|\\
+% |\end{document}|
+% \begin{exam}
+% This example imitates the page numbering format used in this document:
+% \end{exam}
+% |\documentclass{article}|\\
+% |\usepackage[top]{background}|\\
+% |\usepackage{lipsum}|\\
+%
+% |\SetBgContents{-\thepage-}|\\
+% |\SetBgAngle{0}|\\
+% |\SetBgColor{black!40}|\\
+% |\SetBgScale{4}|\\
+% |\SetBgHshift{60}|\\
+% |\SetBgVshift{-5}|\\
+%
+% |\pagestyle{empty}|\\
+%
+% |\begin{document}|\\
+% |\lipsum[1-30]|\\
+% |\end{document}|
+%
+% \begin{exam}\label{exa:bgthispage}
+% This example illustrates how to use of the |\BgThispage| command to add background material
+% on selected pages.
+% \end{exam}
+% |\documentclass{article}|\\
+% |\usepackage[some,top]{background}|\\
+% |\usepackage{lipsum}|\\
+%
+% |\begin{document}|\\
+% |\lipsum[1-5]|\\
+% |\newpage|\\
+% |\SetBgContents{A}\SetBgColor{yellow}|\\
+% |\BgThispage|\\
+% |\lipsum[1-5]|\\
+% |\newpage|\\
+% |\SetBgContents{B}\SetBgColor{blue}|\\
+% |\BgThispage|\\
+% |\lipsum[1-5]|\\
+% |\end{document}|
+%
+% \begin{exam}
+% This example shows how to proceed in order to obtain different background material for the
+% odd and even pages of a document.
+% \end{exam}
+% |\documentclass{article}|\\
+% |\usepackage{background}|\\
+% |\usepackage{lipsum}|\\
+% |\usepackage{ifthen}|\\
+%
+% |\SetBgContents{}|\\
+% |\SetBgOpacity{1}|\\
+% |\SetBgScale{1.5}|\\
+% |\makeatletter|\\
+% |\AddEverypageHook{%|\\
+% | \ifthenelse{\isodd{\thepage}}%|\\
+% | {\SetBgAngle{90}%|\\
+% | \SetBgPosition{0,-.7\textheight}%|\\
+% | \SetBgColor{blue!90}%|\\
+% | \SetBgContents{The background package}}%|\\
+% | {\SetBgAngle{270}%|\\

+% | \SetBgContents{First version}}%|\\
+% | \bg@material}|\\
+% |\makeatother|\\
+%
+% |\begin{document}|\\
+% |\lipsum[1-30]|\\
+% |\end{document}|
+%
+% \begin{exam}\label{exa:nobgthispage}
+% This example\MarNote{Adding the |twocolumn| class option will produce compilation errors}
+% illustrates the use of the |\NoBgThispage| command, to
+% suppress the background material on selected pages (page 2, in this case).
+% \end{exam}
+% |\documentclass{article}|\\
+% |\usepackage{background}|\\
+% |\usepackage{lipsum}|\\

+% \section{Implementation}
+%
+% Standard identification:
+% \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{background}[2009/11/07 v1.0 bg material]
+% \end{macrocode}
+%
+% Now we load the packages that will be used:
+%
+% \begin{macrocode}
+
+\RequirePackage{everypage}
+\RequirePackage{tikz}
+\RequirePackage{afterpage}
+% \end{macrocode}
+%
+% \begin{macro}{\bg@some}
+% A boolean (initially set to |false|) to control whether the background material will be displayed in
+% every page or not.
+% \begin{macrocode}
+
+\newif\ifbg@some
+ \bg@somefalse
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\bg@contents}
+% \begin{macro}{\bg@color}
+% \begin{macro}{\bg@angle}
+% \begin{macro}{\bg@opacity}
+% \begin{macro}{\bg@scale}
+% \begin{macro}{\bg@position}
+% \begin{macro}{\bg@anchor}
+% \begin{macro}{\bg@hshift}
+% \begin{macro}{\bg@vshift}
+% We define the internal control commands and set their default value:
+% \begin{macrocode}
+
+\def\bg@contents{Draft}
+\def\bg@color{red!45}
+\def\bg@angle{60}
+\def\bg@opacity{.5}
+\def\bg@scale{15}
+\def\bg@position{current page.center}
+\def\bg@anchor{}
+\def\bg@hshift{0}
+\def\bg@vshift{0}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% Now we declare the package options:
+% \begin{macrocode}
+
+\DeclareOption{all}{\bg@somefalse}
+\DeclareOption{some}{\bg@sometrue}
+\DeclareOption{center}{%
+ \def\bg@position{current page.center}%
+ \def\bg@anchor{}%
+ \def\bg@angle{60}}
+\DeclareOption{bottom}{%
+ \def\bg@position{current page.south}%
+ \def\bg@anchor{above}%
+ \def\bg@angle{0}%
+ \def\bg@scale{8}}
+\DeclareOption{top}{%
+ \def\bg@position{current page.north}%
+ \def\bg@anchor{below}%
+ \def\bg@angle{0}%
+ \def\bg@scale{8}}
+% \end{macrocode}
+%
+% We next execute and process options in the standard \LaTeX2e way:
+% \begin{macrocode}
+
+\ExecuteOptions{all,center}
+\ProcessOptions
+% \end{macrocode}
+%
+% \begin{macro}{\SetBgContents}
+% \begin{macro}{\SetBgColor}
+% \begin{macro}{\SetBgAngle}
+% \begin{macro}{\SetBgOpacity}
+% \begin{macro}{\SetBgScale}
+% \begin{macro}{\SetBgPosition}
+% \begin{macro}{\SetBgAnchor}
+% \begin{macro}{\SetBgHshift}
+% \begin{macro}{\SetBgVshift}
+% Now comes the definition of the user commands:
+% \begin{macrocode}
+
+\newcommand*\SetBgContents[1]{%
+ \def\bg@contents{#1}}
+\newcommand*\SetBgColor[1]{%
+ \def\bg@color{#1}}
+\newcommand*\SetBgAngle[1]{%
+ \def\bg@angle{#1}}
+\newcommand*\SetBgOpacity[1]{%
+ \def\bg@opacity{#1}}
+\newcommand*\SetBgScale[1]{%
+ \def\bg@scale{#1}}
+\newcommand*\SetBgPosition[1]{%
+ \def\bg@position{#1}}
+\newcommand*\SetBgAnchor[1]{%
+ \def\bg@anchor{#1}}
+\newcommand*\SetBgHshift[1]{%
+ \def\bg@hshift{#1}}
+\newcommand*\SetBgVshift[1]{%
+ \def\bg@vshift{#1}}
+% \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\bg@material}
+% Our main command uses a simple |\node| construct to build the background material.
+% \begin{macrocode}
+
+\newcommand\bg@material{%
+ \begin{tikzpicture}[remember picture,overlay]
+ \node [rotate=\bg@angle,scale=\bg@scale,opacity=\bg@opacity,%
+ xshift=\bg@hshift,yshift=\bg@vshift,color=\bg@color]
+ at (\bg@position) [\bg@anchor] {\bg@contents};
+ \end{tikzpicture}}%
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\BgThispage}
+% A simple application of the |AddThispageHook| command provided by the \package{everypage}
+% package.
+% \begin{macrocode}
+\newcommand\BgThispage{\AddThispageHook{\bg@material}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\NoBgThispage}
+% A hack that perhaps admits improvements. We make a copy of |\bg@material|, and redefine
+% it to be empty on the current page. Then we use the |afterpage| command to restore the
+% original background material.
+% \begin{macrocode}
+
+\newcommand\NoBgThispage{%
+ \let\oldbg@material\bg@material\renewcommand\bg@material{}%
+ \afterpage{\AddEverypageHook{\oldbg@material}}}
+% \end{macrocode}
+% \end{macro}
+%
+% Finally, we check for the boolean |bg@some|; if it is |true|, then no background material is
+% added; otherwise, the material will be added using the |AddEverypageHook| command.
+% \begin{macrocode}
+
+\ifbg@some
+ \AddThispageHook{}
+\else
+ \AddEverypageHook{\bg@material}
+\fi
+% \end{macrocode}
