Ambitus

Ambitus objects are created by: Ambitus_engraver

Standard settings:

axes (list):
'(0 1)

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

X-extent-callback (procedure):
Axis_group_interface::group_extent_callback

Procedure that calculates the extent of this object. If this value is set to #f, the object is empty in the X direction. The procedure takes a grob and axis argument, and returns a number-pair.

Y-extent-callback (procedure):
Axis_group_interface::group_extent_callback

see X-extent-callback.

space-alist (list):
'((clef extra-space . 0.5) (key-signature extra-space . 0.0) (staff-bar extra-space . 0.0) (time-signature extra-space . 0.0) (first-note fixed-space . 0.0))

A table that specifies distances between prefatory items, like clef and time-signature. The format is an alist of spacing tuples: (break-align-symbol type . distance), where type can be the symbols minimum-space or extra-space.

breakable (boolean):
#t

Can this object appear at a line break, like clefs and bar lines?

break-align-symbol (symbol):
'ambitus

This key is used for aligning and spacing breakable items.

break-visibility (procedure):
begin-of-line-visible

A function that takes the break direction and returns a cons of booleans containing (transparent . empty). The following variables are predefined: all-visible, begin-of-line-visible, end-of-line-visible, begin-of-line-invisible, end-of-line-invisible, all-invisible.

This object supports the following interfaces: item-interface, ambitus-interface, break-aligned-interface, axis-group-interface and grob-interface
