[JW Lua] Spacings within a measure

[Jari Williamsson]

Chris,

If you're going to center a single note, all you would basically need is 
the FCMeasure:Width, since the note positioning is at 0 and the note 
uses the same coordinate system as the measure.

However, that would get the note a bit too far to the right, since the 
note positioning is left-aligned. To get it truly optically centered, 
you should look the note width and use FCCellMetrics.HorizontalStretch 
to get a good notehead adjustment within measure coordinates.


This code could also give a good starting point:
---
local m = finale.FCMeasure()
m:Load(1)
if m.SpaceBefore == 0 then
     m.SpaceBefore = m.Width / 2
     m:Save()
end
---


Best regards,

Jari Williamsson
