% \section{Book cover parts and sizes}
% In the following picture we can see a tipical dust jacket. Its main parts are back flap, back, spine, front and front flap. 
% Typographically, a book cover is a dust jacket without flaps, the only difference is that the book cover is a fixed part of the book, whereas the dust jacket is removable.
% \begin{center}
% \includegraphics{figures/cover}
% \end{center}
% When we prepare a cover for printing, some marks are needed to know where to trim or fold the paper. These marks determine a special area of the sheet, which is called ``bleed'' (see the next figure). The background will be expanded onto the bleed, taking account of slight inaccuracy when trimming.
% \begin{center}
% \includegraphics{figures/coverscheme}
% \end{center}
%
% \subsection{Sizes}\label{subsec:sizes}
% We have to give the following sizes to prepare a cover: \texttt{coverwidth}, \texttt{coverheight}, \texttt{spinewidth}, \texttt{flapwidth}, \texttt{marklength}, \texttt{bleedwidth}.
% \begin{center}
% \includegraphics{figures/sizes}
% \end{center}
%
% \subsection{Trimmed version}\label{subsec:trimmed}
% After trimming we get the following result:
% \begin{center}
% \includegraphics{figures/result}
% \end{center}
%
% \subsection{Background parts}\label{subsec:background}
% Important: The bleed is a part of the background!

% \subsection{Loading class}
% The class \texttt{bookcover} requires the services of the class \texttt{article} and the following packages:
% \texttt{kvoptions}, \texttt{geometry}, \texttt{graphicx}, \texttt{calc}, \texttt{xcolor}, \texttt{ifthen}, \texttt{tikz}, \texttt{eso-pic}, \texttt{textpos}.

% \bigskip\noindent
% Load the class as usual, with

% \subsection{Commands}
% This class defines two commands: 
%
% \medskip\noindent
% {\color{newcommand}|\setbookcover|\marg{main layer}\marg{part}\marg{content}}
%
% \medskip\noindent 
% \meta{main layer} (see the following subsubsections)\\ 
% \hspace*{10mm}\texttt{bgcolor}, \texttt{bgpic}, \texttt{bgtikz}, \texttt{fgfirst}, \texttt{fgsecond}
%
% \medskip\noindent The \meta{part} and the \meta{content} depend on the \meta{main layer} (see the following subsubsections).
%
% \medskip\noindent 
% {\color{newcommand}|\makebookcover|}
%
% \subsubsection{Background colors}
% {\color{newcommand}|\setbookcover{bgcolor}|\marg{background part}\marg{colors}}
%
% \medskip\noindent 
% \meta{background part} (see Subsection \ref{subsec:background})\\ 
% \hspace*{10mm}\texttt{back}, \texttt{front}, \texttt{spine}, \texttt{front flap}, \texttt{back flap}, \texttt{whole without flaps}, \texttt{whole}
%
% \medskip\noindent 
% \meta{colors} (options of command |\fill| of package \texttt{tikz})\\ 
% \hspace*{10mm}|color=|\meta{color name} (See \meta{color name} in the package \texttt{xcolor}.)\\ 
% \hspace*{10mm}|top color=|\meta{color name}\\ 
% \hspace*{10mm}|bottom color=|\meta{color name}\\ 
% \hspace*{10mm}|middle color=|\meta{color name}\\ 
% \hspace*{10mm}|inner color=|\meta{color name}\\ 
% \hspace*{10mm}|outer color=|\meta{color name}\\ 
% \hspace*{10mm}|ball color=|\meta{color name}\\ 
% \hspace*{10mm}|shading angle=|\meta{degrees} (This rotates the shading by the given angle.)
%
% \bigskip\noindent\emph{Example:}
%\color{example}
%\begin{verbatim}
%\setbookcover{bgcolor}{whole without flaps}{
%    top color=white, bottom color=blue!50!black, shading angle=60}
%\end{verbatim}
%\color{black}
%
% \subsubsection{Background pictures}
% {\color{newcommand}|\setbookcover{bgpic}|\marg{background part}\marg{picture file}}
%
% \medskip\noindent 
% \meta{background part} (see Subsection \ref{subsec:background})\\ 
% \hspace*{10mm}\texttt{back}, \texttt{front}, \texttt{spine}, \texttt{front flap}, \texttt{back flap}, \texttt{whole without flaps}, \texttt{whole}
%
% \medskip\noindent The picture will be rescaled according to the sizes of the current background part.
%
% \bigskip\noindent\emph{Example:}
%\color{example}
%\begin{verbatim}
%\setbookcover{bgpic}{front flap}{fig.png}
%\end{verbatim}
%\color{black}
%
% \subsubsection{Background Ti\emph{k}Z figures}
% {\color{newcommand}|\setbookcover{bgtikz}|\marg{background part}\marg{tikz code}}
%
% \medskip\noindent 
% \meta{background part} (see Subsection \ref{subsec:background})\\ 
% \hspace*{10mm}\texttt{back}, \texttt{front}, \texttt{spine}, \texttt{front flap}, \texttt{back flap}, \texttt{whole without flaps}, \texttt{whole}
%
% \medskip\noindent
% The Ti\emph{k}Z figure will be placed to the upper left corner of the current background part, without resizeing.
%
% \bigskip\noindent\emph{Example:}
%\color{example}
%\begin{verbatim}
%\setbookcover{bgtikz}{back}{
%    \fill[color=blue](0mm,250mm)--(100mm,250mm)--(100mm,245mm)--(0mm,110mm)--cycle;
%    \fill[color=yellow](5mm,5mm)--(175mm,245mm)--(175mm,0mm)--(5mm,0mm)--cycle;}
%\end{verbatim}
%\color{black}
%
% \subsubsection{First foreground}
% {\color{newcommand}|\setbookcover{fgfirst}|\marg{foreground part}\marg{content}}

% \hspace*{10mm}\texttt{back}, \texttt{front}, \texttt{spine}, \texttt{front flap}, \texttt{back flap}, \texttt{remark}
%
% \medskip\noindent The first foreground is the top layer of the book cover (see Subsection \ref{subsec:layers}).
%
% \bigskip\noindent\emph{Example:}
%\color{example}
%\begin{verbatim}
%\setbookcover{fgfirst}{spine}{
%    \vfill
%    \begin{center}
%        \rotatebox[origin=c]{90}{\bfseries Annales Mathematicae et Informaticae}
%    \end{center}
%    \vfill}
%\end{verbatim}
%\color{black}
%
% \subsubsection{Second foreground}
% {\color{newcommand}|\setbookcover{fgsecond}|\marg{foreground part}\marg{content}}
%
% \medskip\noindent 
% \meta{foreground part} (see Subsection \ref{subsec:foreground})\\ 
% \hspace*{10mm}\texttt{back}, \texttt{front}, \texttt{spine}, \texttt{front flap}, \texttt{back flap}
%
% \medskip\noindent The second foreground is under the first foreground (see Subsection \ref{subsec:layers}).
%
% \bigskip\noindent\emph{Example:} 
% The following code puts a picture behind the `TEXT' on the front cover:
%\color{example}
%\begin{verbatim}
%\setbookcover{fgsecond}{front}{
%    \vfill
%    \begin{center}
%        \includegraphics[width=80mm]{pic.png}
%    \end{center}
%    \vfill}
%\setbookcover{fgfirst}{front}{
%    \vfill
%    \begin{center}
%        TEXT
%    \end{center}
%    \vfill}
%\end{verbatim}
%\color{black}
%
% \subsubsection{Making book cover}
% {\color{newcommand}|\makebookcover|}
%
% \medskip\noindent 
% This command makes the book cover by using contents of background and foreground. 
%
% \subsection{Layers}\label{subsec:layers}
% In the following table we can see the hierarchy of the layers:
%
% \bigskip
% \begin{center}
% \begin{tabular}{@{}ll@{}c@{}}
% \cline{1-2} 
% |fgfirst|  & |back|, |front|, |spine|, |front flap|, |back flap|, |remark|& \color{layer}\emph{top layer}\\ 
% \cline{1-2}
% |fgsecond| & |back|, |front|, |spine|, |front flap|, |back flap|&\color{layer}$\uparrow$\\
% \cline{1-2}
% & |back|, |front|, |spine|, |front flap|, |back flap| &\color{layer}$\uparrow$\\
% |bgtikz| &  |whole without flaps| &\color{layer}$\uparrow$\\ 
% & |whole| &\color{layer}$\uparrow$\\
% \cline{1-2}
% & |back|, |front|, |spine|, |front flap|, |back flap| &\color{layer}$\uparrow$\\
% |bgpic| &  |whole without flaps| &\color{layer}$\uparrow$\\ 
% & |whole| &\color{layer}$\uparrow$\\
% \cline{1-2}
% & |back|, |front|, |spine|, |front flap|, |back flap| &\color{layer}$\uparrow$\\
% |bgcolor| &  |whole without flaps| &\color{layer}$\uparrow$\\ 
% & |whole| & \color{layer}\emph{bottom layer}\\
% \cline{1-2}
% \end{tabular} 
% \end{center}
% \bigskip\noindent For example, in case
%\color{example}
%\begin{verbatim}
%\setbookcover{bgpic}{whole}{fig1.jpg}
%\setbookcover{bgpic}{front}{fig2.jpg}
%\setbookcover{fgsecond}{front}{fig3.jpg}
%\setbookcover{fgfirst}{front}{TEXT}
%\end{verbatim}
%\color{black}
%the \texttt{TEXT} is above the \texttt{fig3.jpg}, the \texttt{fig3.jpg} is above the \texttt{fig2.jpg} and the \texttt{fig2.jpg} is above the \texttt{fig1.jpg}.
