Re: layout-set-staff-size units

[Mats Bengtsson]

I must have dreamt that I tried it. Anyway, it seems that the unit of the
argument is not the same as for global-set-staff-size. If you try
#(layout-set-staff-size (* 14.0 pt))
you will get the correct size. Still, the staff line spacing isn't adjusted
as long as the function is called within a \layout{...} block.

You second example works without any problems in 2.11.7, though.

To summarize (for bug-lilypond), we have at least two bugs:

- The text that I recently added to the manual is wrong, since it
 doesn't include the (* ... pt) to get the correct scaling. However,
 it seems more reasonable to change the function itself to use pt as
 the scale (the function is called internally at some places, which would
 have to be adjusted correspondingly). Example:
\version "2.10.0"
#(set-global-staff-size 16)
\score {
 \relative c' { c d e f }
 \layout { #(layout-set-staff-size 16.0) }
}
\score {
 \relative c' { c d e f }
 \layout { #(layout-set-staff-size (* 16.0 pt)) }
}


- The staff line spacing isn't changed unless you call the function within
 a \paper{...} block, which means that it cannot be used to produce 
different
 staff size of different scores within the same book. Example:

\version "2.10.0"

\score {
 \relative c' { c d e f }
 \layout { #(layout-set-staff-size (* 16.0 pt)) }
}
