LilyPond Internals Reference: 3.1.7 AmbitusLine

### 3.1.7 AmbitusLine

AmbitusLine objects are created by: Ambitus_engraver.

Standard settings:

> `gap` (dimension, in staff space):

>   `ambitus-line::calc-gap`

>   Size of a gap in a variable symbol.

> `length-fraction` (number):

>   `0.7`

>   Multiplier for lengths. Used for determining ledger lines and stem lengths.

> `maximum-gap` (number):

>   `0.45`

>   Maximum value allowed for `gap` property.

> `stencil` (stencil):

>   `ambitus::print`

>   The symbol to print.

> `thickness` (number):

>   `2`

>   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`).

> `X-offset` (number):

>   `ly:self-alignment-interface::centered-on-x-parent`

>   The horizontal amount that this object is moved relative to its X-parent.

This object supports the following interface(s): ambitus-interface, font-interface, grob-interface and item-interface.
