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
