[Therion] Change size of scalebar

[Henry_Bennett at Dell.com]

Seems that you are producing a large format survey which is what I've done.

Try this

    def s_scalebar (expr l, units, txt) =
      begingroup
        interim warningcheck:=0;
        tmpl:=l / Scale * cm * units / 2;
        tmpx:=l / Scale * cm * units / 5;
        tmph:=25bp; % bar height
      endgroup;
      pickup PenC;
      draw (-tmpl,0)--(tmpl,0)--(tmpl,-tmph)--(-tmpl,-tmph)--cycle;
      p:=(0,0)--(tmpx,0)--(tmpx,-tmph)--(0,-tmph)--cycle;
      for i:=-2.5 step 2 until 2:
        fill p shifted (i * tmpx,0);
      endfor;
      begingroup
        interim labeloffset:=3.5bp;
        for i:=0 step (l/5) until (l-1):
          tmpx:=tmpl * (i * 2 / l - 1);
          label.top(thTEX(decimal (i)) scaled 3.6, (tmpx,0));
        endfor;
        label.top(thTEX(decimal (l) & "\thinspace" & txt) scaled 3.6,(tmpl,0));
        label.bot(thTEX("Original Scale = 1 : " & decimal round(Scale*100)) scaled 5.6, (.6cm,-1.6cm)) transformed T;
      endgroup;
    enddef;

I never found a way of making this stuff bigger so that you can print it out on a large banner.  Each element has to be tweaked.

Subject: [Therion] Change size of scalebar

Hello again

Recently I asked how to change size of legendsymbols.
Henry helped on this. Thanks again Henry.

Now my question is how to resize scalebar.
I'm using "Scalebar 2" from this metapost code http://therion.speleo.sk/wiki/doku.php/metapost?s[]=scalebar
As I'm no pro in Metapost or Texcode I don't see how to resize it.
Any help is appreciated.

Btw:
Is there any easy way to resize parts like scalebar, northarrow, legendsymbols, legendcontent?
I'm using all this parts in seperate legendboxes (within layout part in config
file) to position it on seperate places on the map.
Depending on the size of the map it's recomended to make all this single parts bigger to have a nice view of the map.

Thanks,
Torsten
