Re: Lines or Boxes without reference to score or stave

[Guy Stalnaker]

Thanks, Richard, alas, no ... that does nothing that I can discern except errors in lilypond 2.19.x

I'm assuming, therefore, that I don't know what to do with your code. Use \bookTitleMarkup somewhere?

Not sure if it will help, but when creating the book title page for
Denemo I cooked up this:

 bookTitleMarkup = \markup \when-property #'header:title {
     { \postscript #"
                    gsave
                    initmatrix
                    1 setlinewidth 40 40 moveto 517 0 rlineto 0 760
rlineto -517 0 rlineto 0 -760 rlineto  stroke
                    0.5 setlinewidth 45 45 moveto 507 0 rlineto 0 750
rlineto -507 0 rlineto 0 -750 rlineto  stroke
                    grestore" }


I don't remember much about it now, but the gsave and grestore were
things that made the thing work independently of the rest IIRC, so it
may be what you need ...
