3.1.93 NoteCollision

An auxiliary grob to group NoteColumn grobs from several voices, mainly to handle note collisions. See also RestCollision.

NoteCollision objects are created by the following engraver(s): Collision_engraver.

Standard settings:

axes (list):

'(0 1)

List of axis numbers. In the case of alignment grobs, this should contain only one number.

note-collision-threshold (dimension, in staff space):

1

Simultaneous notes that are this close or closer in units of staff-space will be identified as vertically colliding. Used by Stem grobs for notes in the same voice, and NoteCollision grobs for notes in different voices. Default value 1.

prefer-dotted-right (boolean):

#t

For note collisions, prefer to shift dotted up-note to the right, rather than shifting just the dot.

vertical-skylines (pair of skylines):

ly:axis-group-interface::calc-skylines

Two skylines, one above and one below this grob.

X-extent (pair of numbers):

ly:axis-group-interface::width

Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

Y-extent (pair of numbers):

#<unpure-pure-container #<procedure ly:axis-group-interface::height (_)> #<procedure ly:axis-group-interface::pure-height (_ _ _)> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): axis-group-interface, grob-interface, item-interface and note-collision-interface.

This object is of class Item (characterized by item-interface).
