Re: Symmetrical ties in TieColumn

Hi

Currently I'm making some experiments with ties.

What I need is a function that makes all ties in TieColumn have the same length (see attachment). I tried to achieve this by changing some values from Tie.details, but couldn't find the right configuration.

Then I tried to modify shapeTieColumn.ly (http://lists.gnu.org/archive/html/lilypond-devel/2012-06/msg00285.html) but that's probably not the way it should be done.

My question: how difficult would be to write such function?

The problem here is that AFAIK you can't tell LilyPond: here are the attachment points I want for my ties; draw nice ones.

.

I've come up with a sketch which does something like what you want, but you have to play around with numbers to get a good result.

Basically, it draws however many ties you need, but draws them with the same shape, lined up.

You need to specify the shape of one of them by giving a list resembling control points.

The y coordinates in this list are relative to 0. 

The x-coordinates represent the horizontal distance of the control points from the first NoteColumn associated with the TieColumn.

I don't think that makes a lot of sense--and I'm a little too tired to do better--but I fiddling with the numbers should make it clear.

Now the problems :)

Anyway, it's something.
