Re: list of stencils

Hi,
at the moment I solved the problem with postscript as I couldn’t properly deal with the vertical lining of the note-glyph and the line of the markup (it seems to me difficult to move a markup over a staff).
Here is what I did:

dblacknote = {
  \once \override NoteHead.stencil = #ly:text-interface::print
  \once \override NoteHead.text = \markup {
    \combine
    \musicglyph #"noteheads.s2"
    \postscript #"
        newpath
        0.13 setlinewidth
        -0.3 -0.6 moveto
        1.6 0.6 lineto
        stroke"
  }
}

dwhitenote = {
  \once \override NoteHead.stencil = #ly:text-interface::print
  \once \override NoteHead.text = \markup {
    \combine
    \musicglyph #"noteheads.s1"
    \postscript #"
        newpath
        0.13 setlinewidth
        -0.3 -0.6 moveto
        1.7 0.7 lineto
        stroke"
  }
}

The snippet I was referring to was:
circle =
\once \override NoteHead.stencil = #(lambda (grob)
    (let* ((note (ly:note-head::print grob))
           (combo-stencil (ly:stencil-add

note

               (circle-stencil note 0.1 0.8))))
          (ly:make-stencil (ly:stencil-expr combo-stencil)
            (ly:stencil-extent note X)
            (ly:stencil-extent note Y)))) 
{ \circle c' } 

So I wanted to substitute the circle-stencil with some dash-stencil
only… where should I look for a complete list of stencils?
Is it even a proper question?

Thank you for all the help.

Hi Massimiliano, can you include some examples of your lilypond code?

Normally I would create a line as a graphic:
\markup { \draw-line #'(2 . 1)} 

See this page

Hi everybody,
I’m a newbie but already with a, at least for me, not elementary problem.
I want to realise a note head with the original note glyph plus a slash on hte note.
I’ve seen a couple of way to do it: one by overriding the note head stencil with a lambda function and another one by using a combine with a markup.
But, in both cases I need to modify the examples…
and here is the question:  in the first solution, which appears to me the most suitable one, I should modify the stencil… but where do I find a list of all the available stencils (such as the diagonal line)?

Thank you for all the help

Massimiliano
