3.2.7 arpeggio-interface

Functions and settings for drawing an arpeggio symbol.

User settable properties:

arpeggio-direction (direction)

If set, put an arrow on the arpeggio squiggly line.

dash-definition (pair)

List of dash-elements defining the dash structure. Each dash-element has a starting t value, an ending t-value, a dash-fraction, and a dash-period.

line-thickness (number)

For slurs and ties, this is the diameter of the virtual “pen” that draws the two arcs of the curve’s outline, which intersect at the endpoints. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to Staff.StaffSymbol.thickness).

positions (pair of numbers)

Pair of staff coordinates (start . end), where start and end are vertical positions in staff-space units of the current staff. For slurs, this value selects which slur candidate to use; if extreme positions are requested, the closest one is taken.

protrusion (number)

In an arpeggio bracket, the length of the horizontal edges.

script-priority (number)

A key for determining the order of scripts in a stack, by being added to the position of the script in the user input, the sum being the overall priority. Smaller means closer to the head.

thickness (number)

For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to Staff.StaffSymbol.thickness).

Internal properties:

stems (array of grobs)

An array of stem objects.

This grob interface is used in the following graphical object(s): Arpeggio.
