+% \begin{abstract}
+% This small package provides a new macro, which adds fancy reflections at
+% the bottom of graphics. To keep things simple, this new macro can be used
+% in a similar way to the |\includegraphics| macro of the \package{graphicx}
+% package.
+% \end{abstract}
+%
+% \section{Introduction}
+% \label{sec:introduction}
+% Having a fading reflection or mirroring effect at the bottom of graphics can
+% dramatically increase the fancyness of documents and in particular of
+% presentations. Such an effect can be achieved by creating the reflection
+% beforehand with an image editing software or by using the \package{tikz}
+% package. Using Ti\textit{k}Z can be very tricky and many users might not be
+% familiar with describing graphics by writing code. In particular when
+% applying image manipulation operations (like scaling, rotating, trimming) on
+% graphics, handling Ti\textit{k}Z code and positioning nodes correctly can be
+% challenging.
+%
+% To remove this obstacle for inexperienced users and allow them to easily
+% include graphics with fancy reflections, this package offers a simple
+% alternative. By just specifying a graphics file, the macros provided by this
+% package will render it and its reflection automatically.
+%
+% \section{Usage}
+% \label{sec:usage}
+% No big surprise, the package is loaded using:
+% \begin{quote}
+% |\usepackage|\oarg{options}|{reflectgraphics}|
+% \end{quote}
+% The options specified as \meta{options} are globally set for the whole
+% document and can be obliterated by locally defined options. A description of
+% valid options can be found in subsection~\ref{sec:options}.
+%
+% \subsection{Macros}
+% \label{sec:macros}
+% The only new macro provided by this package is:
+% \begin{quote}
+% \DescribeMacro{\reflectgraphics}|\reflectgraphics|\oarg{options}\marg{path}
+% \end{quote}
+% It can be used to render graphics together with their reflections at the
+% bottom, which are fading from a particular starting opacity to fully
+% transparent. The dimensions of a graphic and the properties of its reflection
+% can be defined by \meta{options} (see subsection~\ref{sec:options}).
+%
+% The mandatory argument \meta{path} must contain a valid path to a graphics
+% file of a supported file type. This package internally uses
+% |\includegraphics|. Therefore, basically every graphics type that is
+% supported by |\includegraphics| is also supported by this package. The file
+% extension may be omitted in \meta{path}. To see some examples have a look at
+% subsection~\ref{sec:examples}.
+%
+% \subsection{Options}
+% \label{sec:options}
+% Options can be specified globally with the |\usepackage| statement or locally
+% for each |\reflectgraphics| statement. Local options override values of
+% global options. There are two types of options: the ones that affect graphics
+% and the ones that affect only the rendering of reflections.
+%
+% \paragraph{graphics} The following options describe the properties of
+% graphics.
+%
+% To set the dimensions of the graphic to render, the options
+% \describeoption{width}\option{width}=\meta{dim} and
+% \describeoption{height}\option{height}=\meta{dim} can be specified. If only
+% one of these options is specified, the original aspect ratio will be left
+% untouched. Values passed to these options must be typical \TeX{} dimensions
+% with units like \texttt{cm}, \texttt{em}, \texttt{pt}, and so on.
+%
+% Instead of a manually defining graphics dimensions, the option
+% \describeoption{scale}\option{scale}=\meta{float} can be set as well. Hereby
+% the original aspect ratio and size will be chosen scaled by the provided
+% floating point value. Valid values are all values that are greater than $0$.
+% If either \option{width} or \option{height} is specified, the \option{scale}
+% option will be ignored.
+%
+% The graphics and corresponding reflections can be rotated by specifying the
+% option \describeoption{angle}\option{angle}=\meta{float}. This floating point
+% value describes the rotation angle in degrees. Valid angle values can be
+% positive as well as negative.
+%
+% Similar to |\includegraphics| trimming and clipping can be applied to render
+% only subregions of graphics. This can be done by defining the option
+% \describeoption{trim}\option{trim}=\meta{dim}\ \meta{dim}\ \meta{dim}\
+% \meta{dim}. The option takes four dimension arguments that define the trimming
+% in the following order: \emph{left bottom right top}. If the dimension unit
+% is omitted than \texttt{bp} is used by default, which is similar to
+% |\includegraphics|. Unlike |\includegraphics| the \option{clip} option does
+% not have to be specified.
+%
+% \paragraph{reflections} The following options describe the properties of
+% graphics reflections.
+%
+% The distance between the actual graphic and its reflection can be defined by
+% setting the option \describeoption{distance}\option{distance}=\meta{dim}. If
+% it is not set, a default value of $3.0$\,\texttt{pt} will be used. The
+% specified value must be a \TeX{} dimension.
+%
+% To set the size of the graphics reflection, specify the option
+% \describeoption{length}\option{length}=\meta{float}. This option defines a
+% percentage value, which represents the length (i.\,e.\ the height) of the
+% reflection with respect to the height of the corresponding graphic. Its value
+% is a floating point number and must lie within the interval $[0,1]$. The
+% default value is set to $0.5$, which results in a reflection height that is
+% equal to $50$\,\% of the graphics height.
+%
+% Changing the starting opacity for the fading of the reflection influences the
+% impression how \emph{strong} the reflection is. The opacity can be modified
+% by setting the \describeoption{opacity}\option{opacity}=\meta{float} option.
+% Its value is a floating point number within the interval $[0,1]$. The default
+% value is $0.5$, which equates to $50$\,\% opacity.
+%
+% \subsection{Examples}
+% \label{sec:examples}
+% The simplest way to use |\reflectgraphics| is to omit all optional arguments
+% and let the underlaying |\includegraphics| macro choose the dimensions of the
+% graphic:\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics{lenna.jpg}
+% \end{verbatim}
+% \end{minipage}
+%
+% To change the graphics size in a way whereat the aspect ratio should be kept
+% as it is, define either \option{width}, \option{height} or use the
+% \option{scale} option:\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics[width=4cm]{lenna.jpg}
+% \reflectgraphics[height=4cm]{lenna.jpg}
+% \reflectgraphics[scale=0.25]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=4cm, height=4cm]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
+%
+% If a specific aspect ratio should be forced, both dimensions have to be
+% specified explicitly:\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics[width=4cm, height=2cm]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=4cm, height=2cm]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
+%
+% Rotating graphics can be enabled by specifying the \option{angle} option.
+% Note that rotation will increase the rectangular space (bounding box) that is
+% taken by the graphic and its reflection. In particular the overall height can
+% expand drastically, because the increased height of both the graphic and the
+% reflection add up.\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics[width=1.5cm, angle=45]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=1.5cm, height=1.5cm, angle=15]{lenna.jpg}
+% \reflectgraphics[width=1.5cm, height=1.5cm, angle=30]{lenna.jpg}
+% \reflectgraphics[width=1.5cm, height=1.5cm, angle=45]{lenna.jpg}
+% \reflectgraphics[width=1.5cm, height=1.5cm, angle=60]{lenna.jpg}
+% \reflectgraphics[width=1.5cm, height=1.5cm, angle=75]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
+%
+% To trim and clip graphics together with the corresponding reflection (e.\,g.\
+% to show Lenna's face only), one can straightforward proceed the same way as
+% using |\includegraphics|, except that the \option{clip} option can be
+% omitted:\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics[trim=180 100 125 160]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=1.55cm, height=2cm, trim=180 100 125 160]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
+%
+% In order to get a stronger and more crisp reflection, the options
+% \option{opacity} and \option{length} can be set. For instance, to get a
+% stronger starting opacity of $75$\,\% and a much shorter reflection length of
+% only $20$\,\% of the graphics height, set the following values:\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \reflectgraphics[opacity=0.75, length=0.2]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=4cm, height=4cm, opacity=0.75, length=0.2]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
+%
+% To automatically modify the distance between a graphic and its reflection
+% when dimensions change, the distance and the graphics height can be set in
+% relation to each other. The following code renders graphics with a height of
+% $4$\,\texttt{cm} and sets the distance of the reflection to $10$\,\% of the
+% graphics height ($0.4$\,\texttt{cm}$\null=0.1\cdot4$\,\texttt{cm}):\\
+% \begin{minipage}[t]{\textwidth}
+% \begin{verbatim}
+% \newlength{\len}
+% \setlength{\len}{4cm}
+% \reflectgraphics[height=\len, distance=0.1\len]{lenna.jpg}
+% \end{verbatim}
+% \begin{center}
+% \reflectgraphics[width=4cm, height=4cm, distance=0.4cm]{lenna.jpg}
+% \end{center}
+% \end{minipage}\bigskip
