Re: Changing staff size with custom note head stencils

Hello,  I'm trying to increase the overall size of a given staff, as described in the docs[1] using:

  \new Staff \with {

    fontSize = #2

    \override StaffSymbol #'staff-space = #(magstep 2)

    \override NoteHead #'before-line-breaking = \TwinNoteNoteHeads

  }

But I'm also using custom note head shapes, with an override that references a scheme function  that alters the NoteHead stencil and stem-attachment properties.  

That is preventing the resizing of the note heads.  They just stay the same as the rest of the staff, stems, clefs, etc, become larger.  (This may be related to using "before-line-breaking", but I need to use that to get the horizontal spacing to work properly.[2] )

I have tried various things (including putting the size adjustments in the \layout block [3]) and the only thing I've found that will change the size of the noteheads is using set-global-staff-size [3].  But that also increases the size of all the text (lyrics, chord names, titles, etc), when I just want to increase the size of the staff, not the text.  

Anyone know how to get this to work?  Any advice or pointers would be greatly appreciated.  I realize that this is non-standard stuff, but LilyPond has been amazing at handling whatever I've thrown at it, making it possible to experiment.  A simplified version of my code is below.

Thanks!

Hey Paul,

It'll take a few steps to sort through the problem, but one thing I'd recommend is rewriting all your stencils using internal lilypond code.  Embedded PS, while useable, is a pain in terms of variables - it requires lots of messy string manipulation and makes your code unexportable to SVG.

Check out the path stencil (used to make the eyeglasses markup, for example) - everything you're doing can be rewritten in the same spirit.  Then, to resize it dynamically, just make certain things in the path stencil variables instead of hardcoded values.

Cheers,

MS
