Re: Vertical placement of ottava line

[Peter Crighton]

Thanks, Pierre, that is quite good already, but there is an issue with octavation spanning only one note. See this:

\version "2.19.13"

myOttavaUp = {

  \override Staff.OttavaBracket.stencil = #ly:line-spanner::print

  \override Staff.OttavaBracket.bound-details =

    #`((left . ((Y . 0)

                (stencil-align-dir-y . ,UP)))

       (right . ((Y . 0)

                 (text . ,(make-draw-dashed-line-markup (cons 0 -1.2))))))

  \override Staff.OttavaBracket.left-bound-info =

     #ly:line-spanner::calc-left-bound-info-and-text

  \override Staff.OttavaBracket.right-bound-info =

     #ly:line-spanner::calc-right-bound-info

  \ottava #1

}

myOttavaDown = {

  \override Staff.OttavaBracket.stencil = #ly:line-spanner::print

  \override Staff.OttavaBracket.bound-details =

    #`((left . ((Y . 0)

                (stencil-align-dir-y . ,DOWN)))

       (right . ((Y . 0)

                 (text . ,(make-draw-dashed-line-markup (cons 0 1.2))))))

  \override Staff.OttavaBracket.left-bound-info =

     #ly:line-spanner::calc-left-bound-info-and-text

  \override Staff.OttavaBracket.right-bound-info =

     #ly:line-spanner::calc-right-bound-info

  \ottava #-1

}

\relative c'' {

  c1

  \ottava #1

  c c

  \ottava #-1

  c c

  \ottava #0

  c

  \ottava #1

  c

  \ottava #-1

  c

  \break

  \ottava #0

  c

  \myOttavaUp

  c

  c

  \myOttavaDown

  c

  c

  \ottava #0

  c

  \myOttavaUp

  c

  \myOttavaDown

  c

}

I think the problem is that the 8 is center-aligned above the center of the notehead. (Also in the example with two measures per octavation, which looks not so nice.)

How can I tweak that?

Hi Peter,

2014-09-23 5:03 GMT+02:00 Peter Crighton <address@hidden>:
 

is it possible to Y-offset just the line of an ottavaBracket? I want it to be at the top or bottom of the 8 (depending on va or vb).

Try :

\version "2.18.2"

myOttavaUp = {
  \override Staff.OttavaBracket.stencil = #ly:line-spanner::print
  \override Staff.OttavaBracket.bound-details =
    #`((left . ((Y . 0)
                (stencil-align-dir-y . ,UP)))
       (right . ((Y . 0)
                 (text . ,(make-draw-dashed-line-markup (cons 0 -1.2))))))
  \override Staff.OttavaBracket.left-bound-info =
     #ly:line-spanner::calc-left-bound-info-and-text
  \override Staff.OttavaBracket.right-bound-info =
     #ly:line-spanner::calc-right-bound-info
  \ottava #1
}

myOttavaDown = {
  \override Staff.OttavaBracket.stencil = #ly:line-spanner::print
  \override Staff.OttavaBracket.bound-details =
    #`((left . ((Y . 0)
                (stencil-align-dir-y . ,DOWN)))
       (right . ((Y . 0)
                 (text . ,(make-draw-dashed-line-markup (cons 0 1.2))))))
  \override Staff.OttavaBracket.left-bound-info =
     #ly:line-spanner::calc-left-bound-info-and-text
  \override Staff.OttavaBracket.right-bound-info =
     #ly:line-spanner::calc-right-bound-info
  \ottava #-1
}

\relative c'' {
  \myOttavaUp
  c1
  c1
  \myOttavaDown
  c,,1
  c1
}

HTH,
Pierre
