3.1.52 Hairpin

Hairpin objects are created by: Dynamic_engraver.

Standard settings:

after-line-breaking (boolean):


Dummy property, used to trigger callback for after-line-breaking.

bound-padding (number):


The amount of padding to insert around spanner bounds.

broken-bound-padding (number):


The amount of padding to insert when a spanner is broken at a line break.

circled-tip (boolean)

Put a circle at start/end of hairpins (al/del niente).

grow-direction (direction):


Crescendo or decrescendo?

height (dimension, in staff space):


Height of an object in staff-space units.

minimum-length (dimension, in staff space):


Try to make a spanner at least this long, normally in the horizontal direction. This requires an appropriate callback for the springs-and-rods property. If added to a Tie, this sets the minimum distance between noteheads.

self-alignment-Y (number):


Like self-alignment-X but for the Y axis.

springs-and-rods (boolean):


Dummy variable for triggering spacing routines.

stencil (stencil):


The symbol to print.

thickness (number):


Line thickness, generally measured in line-thickness.

to-barline (boolean):


If true, the spanner will stop at the bar line just before it would otherwise stop.

vertical-skylines (pair of skylines):

#<unpure-pure-container #<primitive-procedure ly:grob::vertical-skylines-from-stencil> #<primitive-procedure ly:grob::pure-simple-vertical-skylines-from-extents> >

Two skylines, one above and one below this grob.

Y-extent (pair of numbers):

#<unpure-pure-container #<primitive-procedure ly:grob::stencil-height> #<primitive-procedure ly:hairpin::pure-height> >

Hard coded extent in Y direction.

Y-offset (number):

#<unpure-pure-container #<primitive-procedure ly:self-alignment-interface::y-aligned-on-self> #<primitive-procedure ly:self-alignment-interface::pure-y-aligned-on-self> >

The vertical amount that this object is moved relative to its Y-parent.

This object supports the following interface(s): dynamic-interface, grob-interface, hairpin-interface, line-interface, self-alignment-interface and spanner-interface.
