[JW Lua] Page-relative Units

[M. R. Miller]

Thanks for the quick response, Jan! That works perfectly.

I had ignored it because of the documentation. Not sure if there's a place to file documentation issues, but FCArticulation::CalcMetricPos should be marked as Lua-supported. Metric position also made me think musical position within the measure rather than graphical position, despite the FCPoint* argument. A more clear doc text could maybe be something like:

"Calculate the coordinates of the articulation's handle in page-relative EVPU."

CalcMetricPos() is the method which exists for both FCArticulation and FCExpression.
In FCSmartShape it's similar: CalcLeft/RightCellMetricPos for measure-attached, CalcLeft/RightEntryMetricPos for note-attached smart shapes.

Hey all,

Is there a good way to get an articulation's position relative to the page? I see FCArticulation::GetVerticalPos but this appears to be an offset relative to different anchors based on the articulation definition's AutoPosSide.

Same question for FCExpression which has a different alignment scheme but similarly only gives offsets. And I can't seem to find any positioning info about smart shapes.

For context, I'm writing a Lua script to draw a bounding box that encompasses all the elements in a region. I've got it working with notes and rests using FCEntryMetrics and FCCellMetrics but can't seem to find a convenient way to get the articulation and expression placement in the same page-relative coordinates.

Any suggestions?

Thanks!
