[Therion] Height numbers in square boxes

Thu Sep 20 21:38:40 CEST 2018

One of the developers added a NZSS symbol set some years ago, based on a few symbol definitions I posted on this forum.

I have some more symbol definitions I would like to add to it, btw.

If someone points me to the general code location, I might try to cut my teeth on git and add those extra definitions.

A new symbol set can include as little as a single symbol, so it should not be a big job Bill.  You can simply reassign symbols from other symbol sets for those not defined in your chosen symbol set.  ie

  symbol-assign line gradient UIS

  symbol-assign point gradient UIS

Maybe some learning we can do together Bill (on adding to symbol sets).

Also for what it is worth, I made this clumsy attempt at text within boxes (or sorts).  Not quite what you are after, but might give some ideas.

A more generally useful thing I have been wondering about for point labels and point remarks (or line labels for that matter) would be the ability to add a box around the text, as a simple property of that entity, activated in the same way as we specify -align left or -scale xs.  And even a -hyperlink [path|url] would be useful

# Define an experimental label symbol for graffiti

code metapost

def p_u_graffiti (expr pos,theta,sc,al)=

  U:=(.2u,.5u);

  T:=identity aligned al rotated theta scaled sc shifted pos;

  %# pos and al work fine in label below, but theta and sc transformed about far off point???

  %# so have been disabled for label component.  Plan rotation seems to have no further detrimental effect

  label (btex Gr etex, pos) aligned al; % rotated theta scaled sc aligned al;  % btex and etex are wrappers around code to be process by tex

  thdraw unitsquare scaled u shifted (-0.5u,-0.5u) rotated 45 withpen PenD; % diagonal box with thin pen

  thdraw fullcircle scaled u withpen PenD;  

enddef;

initsymbol("p_u_graffiti")

endlayout LayoutMapThisCave

#legend entries for custom entities

text en "point u:graffiti" "Historic graffiti" #text to appear in legend

Regards

Bruce
