[therion] scale / base-scale question

[Stacho Mudrak]

Font sizes setup is very simple, just add to layout following lines:

  code metapost
  fonts_setup(14,16,20,28,40);

Some remarks:

Default is fonts_setup(7,8,10,14,20) for 1:200, so the above command will double font sizes.

Sizes 7,8,10,14,20 are the font sizes for xs,s,m,l,xl fonts. In the output map, these sizes are mupltiplied by optical scale (1/2.5 in this case). So if you want medium font to be 10 point size, it needs to be set to 10 * 2.5 = 25 pt :)

OK, it sounds complicated, but it is very simple.

To fix the waterflow arrow bug, add following metapost code to your layout.

 code metapost
 def p_waterflow_permanent (expr pos,theta,sc,al)=
    U:=(.15u,.5u);
    T:=identity aligned al rotated theta scaled sc shifted pos;
    pickup PenC;
    p:=(0,.5u){down}..(.12u,.3u)..(-.15u,.15u)..(.13u,0)..
        (-.08u,-.2u)..{down}(0,-.5u);
    p:=p rotated 180;
    thdraw p;
    oldahlength:=ahlength; ahlength:=2.5pt * optical_zoom;
    thdraw arrowhead p;
    thfill arrowhead p;
    ahlength:=oldahlength;
 enddef;

It is still "cheating", but it should help you. If not or you are using other waterflow symbols, please let me know. In the next release, these problems should be fixed.
