3.1.99 PaperColumn

An auxiliary grob grouping musical items to handle the flexible horizontal space between musical and non-musical columns. See also NonMusicalPaperColumn.

PaperColumn objects are created by the following engraver(s): Paper_column_engraver.

Standard settings:

allow-loose-spacing (boolean):

#t

If set, column can be detached from main spacing.

axes (list):

'(0)

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

font-size (number):

-7.5

The font size, compared to the ‘normal’ size. 0 is style-sheet’s normal size, -1 is smaller, +1 is bigger. Each step of 1 is approximately 12% larger; 6 steps are exactly a factor 2 larger. If the context property fontSize is set, its value is added to this before the glyph is printed. Fractional values are allowed.

horizontal-skylines (pair of skylines):

ly:separation-item::calc-skylines

Two skylines, one to the left and one to the right of this grob.

keep-inside-line (boolean):

#t

If set, this column cannot have objects sticking into the margin.

layer (integer):

1000

An integer which determines the order of printing objects. Objects with the lowest value of layer are drawn first, then objects with progressively higher values are drawn, so objects with higher values overwrite objects with lower values. By default most objects are assigned a layer value of 1.

skyline-vertical-padding (number):

0.08

The amount by which the left and right skylines of a column are padded vertically, beyond the Y-extents and extra-spacing-heights of the constituent grobs in the column. Increase this to prevent interleaving of grobs from adjacent columns.

X-alignment-extent (pair of numbers):

'(0 . 1.35)

If a grob wants to align itself on a PaperColumn grob that doesn’t contain note heads, use this horizontal extent as a placeholder.

X-extent (pair of numbers):

ly:axis-group-interface::width

Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): axis-group-interface, font-interface, grob-interface, item-interface, musical-paper-column-interface, paper-column-interface, separation-item-interface and spaceable-grob-interface.

This object is of class Paper_column (characterized by paper-column-interface).
