[Therion] Change Size of Legensymbols and Text

[Henry_Bennett at Dell.com]

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!

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
