You need to add this to your th config.  Tweak the numbers to find what works for you.

 

Code metapost

   def draw_legend_box =

        %make the objects in the legend boxes bigger

        currentpicture := currentpicture scaled 7.0;

        clip currentpicture to unitsquare scaled 20u;

        drawoptions();

        pickup PenB;

        draw unitsquare scaled 20u ;

    enddef;

 

    %clear the background of the larger legend boxes   

    def clean_legend_box =

        unfill unitsquare scaled 20u;

    enddef;

   

    %change the value of inscale to fill the legend boxes

    def inscale =

        %xscaled legend_scale yscaled (0.618*legend_scale)

        xscaled legend_scale yscaled legend_scale

    enddef;

endcode

 

code tex-map

  \def\maplayout{

    \legendbox{75}{80}{NW}{

      \legendwidth 140 cm

      \legendtextsize={\size[54]}

      \hsize=\legendwidth

      \input th_legend

      }

  }

endcode #end of TeX code

 

You may also find this useful, from memory it was how I sorted the altitude legend box too.

This works for me for virtually all the symbols except for passage height which needs some additional thought. 

Enjoy!

Subject: [Therion] Change Size of Legensymbols and Text

Hi

I'm wondering if it's possible to change the size of the legendsymbols and it's text in a simple way.
Does anyone have an idea?

Within the layout passage in the th-config file I use a separate legendbox for just the legendsymbols:
...
\legendbox{10}{10}{SE}{\legendsymbols}
...
\legendsymbols is defined as follows:
code tex-map
\def\legendsymbols{
\hsize=\legendwidth
\formattedlegend
}

As the map is pretty big the legendsymbols are pretty small in comparision.
And there is a lot free space for much bigger legendsymbols.

cheers,
Torsten
