Distance parameter for "\mrcmarker"

[rolfn]

I created a map similar to the example in the manual:

    ...
    {
      \mrcmarker{named position=\city,type=knob,fill=red!20,draw=red,
        radius=2mm}
      \mrcmarker{named position=\city,type=pin,fill=blue!10,draw=blue,
        contents=\name}
    }
   ...

The result would look better if I could reduce the distance between the pin marker and the city position. How can it work? The following picture shows the problem. Many thanks in advance.

For the type pin, there is no distance customization (yet).

But you can create your own marker type as documented. One way is to copy and modify some package code. In the following example, a new marker xpin is made from pin with an distance modifier \mydistance. If \mydistance is set to 0.5, you have the original pin distance.

\def\mydistance{0.25}

\ExplSyntaxOn

\__mermap_new_marker_type:nn {xpin}
  {
    \path[fill=mrcmarkerfill,draw=none,fill~opacity=0.7]
      (0,0) -- (0.1,\mydistance) -- (-0.1,\mydistance) -- cycle;
    \node[fill=white,draw=none,text=mrcmarkertext,
      above,font=\mrcmarkerfont,inner~sep=0.5mm,align=center,
      line~width=0mm,xshift=\mrcmarkershift,
      fill~opacity=0.7,text~opacity=1,xshift=0mm,mrcnodestyle]
      (pin_node) at (0,\mydistance) {\mrcmarkercontents};
    \path[draw=mrcmarkerdraw,fill=none,line~join=round,mrcpathstyle]
      (0,0) -- (0.1,\mydistance) -- (pin_node.south~east) -- (pin_node.north~east)
      -- (pin_node.north~west) -- (pin_node.south~west)
      -- (-0.1,\mydistance) [line~join=bevel] --  cycle;
  }

\ExplSyntaxOff

Thanks a lot. This helps.

I incorporated this distance feature to pin into Version 1.02 (2020-08-06).

Many Thanks.
