[JW Lua] Slurs Data...

Jan,

So I looked at it and I’m at the same point. Thanks though, for pointing out the weird semantic of the endpoints.

I’ll try to phrase it differently: if I just want to change the height of a non-edited slur and nothing else, right now, I would need to know the other 2 (or 3) parameters of the control points. Since to change the height (ctrlpoint:SetControlPoint1OffsetY() and ctrlpoint:SetControlPoint2OffsetY()) I need to put the slur in "ctrlpoint:SetCustomShaped(true)”, as soon as I do it, all parameters are reset to zero.

In your example, you’re giving new values to all 4 parameters, which I understand.

I’m looking for a way to make an actual “read out” of the default values. The only way that I can see right now is to move manually the slur (and back to its original position) and then, Finale considers that the slur is “custom” and I can get through LUA an actual read out of all 4 parameters of the controlpoints.

Here’s a snippet:

local marks = finale.FCSmartShapeMeasureMarks()
marks:LoadAllForRegion(finenv.Region(), true)
for mark in each(marks) do
     local smartshape = mark:CreateSmartShape()
     if (smartshape ~= nil) and smartshape:IsSlur() then
         local leftseg=smartshape:GetTerminateSegmentLeft()
         local rightseg=smartshape:GetTerminateSegmentRight()
         ctrlpoint=smartshape:GetCtrlPointAdjust()

-- ctrlpoint:SetCustomShaped(true)-- if used on a non-edited slur, I get a flat line (and zero for all parameters)


print("vertical left =", ctrlpoint:GetControlPoint1OffsetY())
print("vertical right =", ctrlpoint:GetControlPoint2OffsetY())
print("custom =",ctrlpoint:GetCustomShaped())

        -- smartshape:Save()
     end
end

This will return:

vertical left = 0
vertical right = 0
custom = true

for a non-edited slur,

And this, on a manually edited slur:

vertical left = 60 (actual read out)
vertical right = 60 (actual read out)
custom = true
