Book, set-global-staff-size & set-paper-size

[Pierre Perol-Schneider]

Hi List,

Please consider the following code:

\version "2.18.2"
%\version "2.19.16" %% <= same result

accords = \chordmode { c1 g1:7 }
musique = \relative c' { c4 d e f g1 }
paroles = \lyricmode { bla bla bla bla bla }

%#(set-global-staff-size 30)
\book {
  \bookOutputSuffix "a4"
  \paper {
    #(set-paper-size "a4")
  }
  \score {
    <<
      \new ChordNames \accords
      \musique
      \addlyrics \paroles
    >>
  }
}

%#(set-global-staff-size 10)
\book {
  \bookOutputSuffix "a5"
  \paper {
    #(set-paper-size "a5")
  }
  \score {
    <<
      \new ChordNames \accords
      \musique
      \addlyrics \paroles
    >>
  }
}

%#(set-global-staff-size 5)
\book {
  \bookOutputSuffix "a6"
  \paper {
    #(set-paper-size "a6")
  }
  \score {
    <<
      \new ChordNames \accords
      \musique
      \addlyrics \paroles
    >>
  }
}

As soon as 'set-global-staff-size' are uncommented, 'set-paper-size' are no more taken into account.

Any reason for this ?

Am I missing something ?

TIA,

Pierre
