Re: Available font sizes in Lilypond preview

Sorry, yes. my mistake, I AM now seeing exported Lilypond files that match the Lilypond print pre-views.

I am also getting roughly the outputs I expect when I edit the Lilypond file to change the global-staff-size. As far as I can tell, Lilypond does operate with values other than the Rosegarden pre-set list. The "Basic Options" - Font size setting in the Lilypond export options dialog appears to set the "global-staff-size" parameter in the resulting Lilypond file, rather than a font size as such. Presumably Lilypond itself then chooses text & note font sizes compatible with that staff size. So we can use the staff size as a convenient global scaling parameter.

Having pre-sets, as at present, and also allowing arbitrary staff size entry might be a useful change for Rosegarden in the future. Adjusting score size to fit exactly into a set of pages is a tricky business.

You must have done something to cause the difference. Here's a file I
previewed and then exported, using identical settings in the export dialog
both times, and without changing anything in between:

e3cd49b5f3ec7209f9151329fa43da1b6fc1503c 609_lilypondview/rosegardenv5zlPa.ly
e3cd49b5f3ec7209f9151329fa43da1b6fc1503c exported.ly

Exactly the same.

I think I'm the one who implemented this originally. If not, I had a hand in
it along the way, because I have a clear memory of offering all the point
sizes that were valid in LilyPond at that time.

Perhaps this limitation is no longer true. LilyPond has changed a great deal
since those days. I'll investigate this as soon as I get a chance.
