\section{Markers}%
As described before, a map can be amended by arbitrary \tikzname\ code
using map coordinates.
For highlighting places or adding markers, the \refCom{mrcmarker} macro
may be helpful which provides some predefined marker types.

%-------------------------------------------------------------------------------
\subsection{Marker Settings}

\begin{docCommand}{mrcmarker}{\marg{options}}
  Places a marker according to the given \meta{options} on the map.
  All \meta{options} share the common prefix |/mermap/marker/|.
  Different \refKey{/mermap/marker/type} settings are available which are
  more or less customizable.

\tikzsetnextfilename{marker_mrcmarker}%
\begin{dispExample}
% \mrcsetapikey{thunderforest}{YOUR-API-KEY} % registered key
\begin{tikzpicture}
  \mrcmap[type=reference, position=48.15:11.6,
    flex reference scale=500 000,
    source=thunderforest neighbourhood,
    tex width=\linewidth,tex height=4cm]{}
  \mrcdrawmap
  \node[below,font=\fontsize{7pt}{7pt}\sffamily] at (mrcmap.south)
    {\mrcmapattribution};
  \mrcdrawnetwork
  \mrcclipmap

  \mrcmarker{type=classic, position=48.15:11.2, contents={A}, radius=0.5mm}
  \mrcmarker{type=pin,     position=48.15:11.3, contents={B}}
  \mrcmarker{type=pinflip, position=48.15:11.4, contents={C}}

  \mrcmarker{type=markx,   position=48.15:12,   contents={I}}
\end{tikzpicture}
\end{dispExample}
\end{docCommand}


\begin{docCommand}{mermapsetmarker}{\marg{options}}
  Sets \meta{options} for all following markers inside the current \TeX\ group.
  All options share the common prefix |/mermap/marker/|, e.g. for setting
  \refKey{/mermap/marker/type} use
  \begin{dispListing}
    \mermapsetmarker{type=pin}
  \end{dispListing}
  Also see \refCom{mermapset} and \refCom{mermapsetsupply}.
\end{docCommand}

  \emph{after} the options of \refCom{mrcmarker}.
\end{docMrcKey}

\begin{docMrcKey}{marker/latitude}{=\meta{latitude}}{no default, initially |12|}
  Latitude degree of the place marker.
  It is accessible as \docAuxCommand{mrcmarkerlatitude} (use read-only).
\end{docMrcKey}

\begin{docMrcKey}{marker/lat}{=\meta{latitude}}{no default, initially |12|}
  Alias for \refKey{/mermap/marker/latitude}.

\begin{docMrcKey}{marker/lon}{=\meta{longitude}}{no default, initially |49|}
  Alias for \refKey{/mermap/marker/longitude}.
\end{docMrcKey}

\begin{docMrcKey}{marker/position}{=\meta{place latitude}:\meta{place longitude}}{no default, initially |12:49|}

\end{docMrcKey}

\begin{docMrcKey}{marker/named position}{=\meta{name}}{style, no default}
  Sets the latitude degree and the longitude degree of the place marker
  to the \emph{named position} denoted by \meta{name}, see \Fullref{sec:names_positions}.
\end{docMrcKey}

\begin{docMrcKey}{marker/use inside}{=\meta{area}}{no default, initially |map|}
  The place marker is used or ignored according to its belonging inside the
  given \meta{area}. Feasible values for \meta{area} are:
  \begin{itemize}
  \item\docValue{map}: Use inside map.
  \item\docValue{vicinity}: Use inside map plus vicinity, see \refKey{/mermap/vicinity}.
  \end{itemize}
\end{docMrcKey}


\begin{docMrcKey}{marker/contents}{=\meta{text}}{no default, initially empty}
  Sets \meta{text} for displaying inside the marker, if
  the marker type supports such a thing.
  It is accessible as \docAuxCommand{mrcmarkercontents} (use read-only).
\end{docMrcKey}

\begin{docMrcKey}{marker/pictocontents}{=\meta{code}}{no default, initially empty}
  Sets \tikzname\ \meta{code} for displaying inside the marker, if
  the marker type supports such a thing.
  It is accessible as \docAuxCommand{mrcmarkerpictocontents} (use read-only).
\end{docMrcKey}

\begin{docMrcKey}{marker/alias}{=\meta{text}}{no default, initially |noname|}
  The position of the marker is available as \tikzname\ coordinate by
  the given \meta{text}, e.g. to draw to or from the marker.
\end{docMrcKey}

\begin{docMrcKey}{marker/uuid}{=\meta{uuid}}{no default, initially empty}
  Sets a \meta{uuid} for unique identification of markers.
  It is accessible as \docAuxCommand{mrcmarkeruuid} (use read-only).
  The \meta{uuid} is provided for user applications.

  Sets a \meta{category} to group markers.
  It is accessible as \docAuxCommand{mrcmarkercategory} (use read-only).
\end{docMrcKey}

\clearpage

\begin{docMrcKey}{marker/show}{\colOpt{=true\textbar false}}{default |true|, initially |true|}
  If set to |true|, the marker is shown, if it lies inside the map (or vicinity).
  Otherwise, the place marker is not used.
\end{docMrcKey}


\begin{docMrcKey}{marker/hide}{\colOpt{=true\textbar false}}{default |true|, initially |false|}
  If set to |true|, the marker is not used.
  \refKey{/mermap/marker/hide} is inverse to \refKey{/mermap/marker/show}.
\end{docMrcKey}



\begin{docMrcKey}{marker/show category}{=\meta{category}}{style, no default}
  Sets \refKey{/mermap/marker/show} to |true|, if \refKey{/mermap/marker/category} equals \meta{category}.
  Otherwise, nothing happens.
  \refKey{/mermap/marker/category} has to be set \emph{before}.
\end{docMrcKey}


\begin{docMrcKey}{marker/show all but category}{=\meta{category}}{style, no default}
  Sets \refKey{/mermap/marker/show} to |true|, if \refKey{/mermap/marker/category} does not equal \meta{category}.

\begin{docMrcKey}{marker/path style}{=\marg{options}}{no default, initially empty}
  \tikzname\ \meta{options} which are added to (some) path elements of

\subsection{New Marker Types}

\begin{docCommand}{mrcnewmarkertype}{\marg{type name}\marg{\tikzname\ code}}
  Creates a new \refKey{/mermap/marker/type} value \meta{type name} using the
  given \meta{\tikzname\ code} for drawing a place marker.
  To avoid future name clashes, you should start a private \meta{type name}
  with letter |x|. For \meta{\tikzname\ code} settings like
  \docAuxCommand{mrcmarkercontents},
  \docAuxCommand{mrcmarkerfont}, or \docColor{mrcmarkerfill} may be used
  or ignored.

  \tikzsetnextfilename{marker_xmark}%
  \begin{dispExample}
  \mrcnewmarkertype{xmark}{
    \path[draw=mrcmarkerdraw,thick] circle (\mrcmarkerradius);
    \path[draw=mrcmarkerdraw,thick]
       (45:2*\mrcmarkerradius)--(225:2*\mrcmarkerradius)
       (135:2*\mrcmarkerradius)--(315:2*\mrcmarkerradius);
  }

  \mrcmap[tex width=4cm, tex height=4cm,
    latitude=48.14, longitude=11.57, target=none]{}
  \mrcdrawmap[draw=path]
  \mrcmarker{type=xmark,

\subsection{New Marker Styles}

\begin{docCommand}{mrcnewmarkerstyle}{\marg{style name}\marg{options}}
  Creates a new \refKey{/mermap/marker/style} value \meta{style name} using the
  given \meta{options} for drawing a place marker.
  All \meta{options} share the common prefix |/mermap/marker/|. Here, a \emph{style}
  has the same concept as a \tikzname\ style.

  \tikzsetnextfilename{marker_markerstyle}%
  \begin{dispExample}
  \begin{tikzpicture}
  \mrcmap[tex width=8cm, tex height=4cm, zoom=10,
    latitude=48.14, longitude=11.48, target=none]{}
  \mrcdrawmap[draw=path]
  \mrcnewmarkerstyle{one}{type=pin, draw=blue, fill=blue!20!white,
    font=\sffamily\footnotesize}
  \mrcnewmarkerstyle{two}{type=pinflip, draw=red, fill=red!20!white,
    font=\sffamily\footnotesize}
  \mrcmarker{style=one, position=48.14:11.36, contents={Germering}}
  \mrcmarker{style=two, position=48.14:11.57, contents={M\"unchen}}
  \end{tikzpicture}
  \end{dispExample}

  A \emph{style} can have one parameter, but note the small difference
  in applying this parameter compared to \tikzname:

  \tikzsetnextfilename{marker_markerstyle2}%
  \begin{dispExample}
  \begin{tikzpicture}
  \mrcmap[tex width=8cm, tex height=4cm, zoom=10,
    latitude=48.14, longitude=11.48, target=none]{}
  \mrcdrawmap[draw=path]
  \mrcnewmarkerstyle{color}{type=pin, draw=#1, fill=#1!20!white,
    font=\sffamily\footnotesize}
  \mrcmarker{style/color=blue, position=48.14:11.36, contents={Germering}}
  \mrcmarker{style/color=red, position=48.14:11.57, contents={M\"unchen}}
  \end{tikzpicture}
  \end{dispExample}
\end{docCommand}


\begin{docMrcKey}{marker/style}{=\meta{style name}}{no default, initially unset}
  Applies a given \meta{style name}, i.e. all options which were stored
  by \refCom{mrcnewmarkerstyle} under this name.
\end{docMrcKey}
