Hi, all.
I'm attempting to create some music functions that have some
postscript commands in them. Is there a way to pass an argument from
the Scheme music function into the embedded postscript? Here's a
simplified example that makes a hollow square notehead:
The function:
sample =
#(define-music-function (parser location thickness note )
(number? ly:music?)
#{
\once \override NoteHead #'stencil = #ly:text-interface::print
\once \override NoteHead #'text = \markup {
\postscript #"
-1.65 0 translate
0.25 setlinewidth
0.75 -0.4 0.8 0.8 rectstroke"
}
$note
#})
Usage:
\sample #0.25 bf2
What I want to do is have the value of the "thickness" variable
replace the "0.25" in the postscript. I've tried everything that I can
think of and have also looked in some postscript documentation. Is
there a way to do this? It would allow me to solve a lot of things I
want to do with Lilypond.
I'm not sure if I should post questions like this here or to the devel
forum. I did not cross-post so let me know if I should repost there.
Thanks,
-Eric
