Standard settings:

axes (list):

'(0 1)

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

break-align-symbol (symbol):


This key is used for aligning and spacing breakable items.

break-visibility (vector):

#(#f #f #t)

A vector of 3 booleans, #(end-of-line unbroken begin-of-line). #t means visible, #f means killed.

non-musical (boolean):


True if the grob belongs to a NonMusicalPaperColumn.

space-alist (list):

'((cue-end-clef extra-space . 0.5) (clef extra-space . 0.5) (cue-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.

X-extent (pair of numbers):


Hard coded extent in X direction.

Y-extent (pair of numbers):


Hard coded extent in Y direction.

This object supports the following interface(s): ambitus-interface, axis-group-interface, break-aligned-interface, grob-interface and item-interface.
