Lyrics overlap when placed in different layers

axgeertinger commented 3 weeks ago

When syllables belonging to the same verse are placed across different layers due to rhythmic variants, the spacing algorithm does not seem to be aware of collisions.

What would be the expected order? Do you have some publication examples?

craigsapp commented 1 week ago

I would expect this layout:

The main thing is that the first syllable of the second verse does not have an offset (unlike the first note of the second verse).

Often the first two notes for the second verse will be cue sized to increase readability.

@craigsapp Exactly. This is the printed source. samson_pigens_sang

Unfortunately fixing this will require some in-depth refactoring of the lyric layout algorithm.

In the meantime, the best work-around I can think of is to put the beam in the second layer. This is clearly not optimal, but at least the rendering outcome it correct.
