[Therion] Height numbers in square boxes

[Bruce Mutton]

Thanks Martin, and Stacho, for your collected efforts.

I’ll try out and digest all of those suggestions, and put something on the wiki in due course.

 

I started wondering if a similar thing could be done for ‘line label’ (for say boxed or filled) but looking at the code it seems like that would be a much bigger chunk of work, as the mode concept is not implemented there.

 

Thanks again

 

Bruce

If I wanted to box just one or two text labels, night it be possible to pass this parameter using a standard ‘point label’ entity with a ‘mode’ option?

Or would we have to go down a user defined label route?

 

Hi,

 

there is no such option, but you can use custom attribute, let's name it "label_mode":

 

-attr label_mode 6

 

Than you just need to redefine the label macro to use it:

 

vardef p_label@#(expr txt,pos,rot,mode_) =

  if known ATTR_label_mode:

    mode := scantokens(ATTR_label_mode);

  else:

    mode := mode_;

  fi;

  if (mode=1) or (mode=7): interim labeloffset:=(u/8) fi;

  lab:=thelabel@#(txt, pos);

  if mode>1: pickup PenD fi;

  if mode=1:

    pickup pencircle scaled (u/6);

    drawdot(pos);

    process_label(pos,0);

  elseif mode=2: process_uplabel;       

  elseif mode=3: process_downlabel;

  elseif mode=4: process_updownlabel;

  elseif mode=5: process_circledlabel;

  elseif mode=6: process_boxedlabel;

  elseif mode=7: process_label(pos,rot);  % station name

  elseif mode=8: process_filledlabel(pos, rot);

  else: process_label(pos,rot); fi;

enddef;

 

Best regards,

Martin
