I'm not sure I completely understand what you ask, but here are two
suggestions:
1) If you are interested in vector-drawn characters and are willing
to define them yourself (which is I think what you are try to
show above), how about writing a program like:
pro metsym,x,y,sym,symsize
if (sym eq 0) then begin
plots,/100.0*symsize+x,/100.0*symsize+y
plots,[etc.
endif
if (sym eq 1) then begin
plots,/100.0*symsize+x,[0,100,20,0]/100.0*symsize+y
plots,[etc.
endif
return
end
2) If you are interested in a bit-mapped font set, I do have something
you might use: one program takes a large image which contains
the whole symbol set in it and separates all the symbols into a specific
format and saves that. the other program is similar to xyouts, taking
x,y,string and then a fontname... the letters are TV'ed onto the screen
from the stored bitmap font file. I use this when I need big block letters
on the screen, larger than what my X font library contains.
hope this helps a little..
Eric
