PercentRepeat

PercentRepeat grobs are created by: Percent_repeat_engraver

percent-repeat-interface

Repeats that look like percent signs

slope (number):

some kind of slope Default value: 1.0

thickness (number):

thickness, measured in stafflinethickness. Default value: 0.48

font-interface

Any symbol that is typeset through fixed sets of glyphs (ie. fonts)

font-style (symbol):

a precooked set of font definitions, eg. finger volta timesig mark script large Large dynamic. Default value: (unset)

font-series (symbol):

partial font definition: medium, bold. Default value: (unset)

font-shape (symbol):

partial font definition: upright or italic. Default value: (unset)

font-family (symbol):

partial font definition: music roman braces dynamic math ... Default value: 'music

font-name (symbol):

partial font definition: base name of font file FIXME: should override other partials. Default value: (unset)

font-design-size (number):

partial font definition: exact font size in points FIXME: should override font-relative-size. Default value: (unset)

font-relative-size (number):

partial font definition: the relative size compared the `normal' size. 0 is style-sheet's normal size, -1 is smaller, +1 is bigger, -1 is smaller. Default value: (unset)

multi-measure-rest-interface

A rest that spans a whole number of measures. For typesetting the numbers, fields from font-interface may be used.

padding is the space between number and rest. Measured in staffspace.

columns (list):

list of grobs, typically containing paper-columns, list of note-columns. Default value: (unset)

expand-limit (integer):

maximum number of measures expanded in church rests. Default value: (unset)

minimum-width (number):

minimum-width of rest symbol, in staffspace. Default value: 12.5

padding (number):

add this much extra space between objects that are next to each other. Default value: (unset)

general-grob-interface

All grobs support this

X-offset-callbacks (list):

list of functions, each taking an grob and axis argument. The function determine the position relative to this grob's parent. The last one in the list is called first. Default value: (unset)

Y-offset-callbacks (list):

see X-offset-callbacks. Default value: (unset)

X-extent-callback (procedure):

procedure taking an grob and axis argument, returning a number-pair. The return value is the extent of the grob. Default value: (unset)

Y-extent-callback (procedure):

see X-extent-callback. Default value: (unset)

molecule-callback (procedure):

Function taking grob as argument, returning a Scheme encoded Molecule. Default value: #<primitive-procedure Multi_measure_rest::percent>

font-relative-size (number):

partial font definition: the relative size compared the `normal' size. 0 is style-sheet's normal size, -1 is smaller, +1 is bigger, -1 is smaller. Default value: (unset)

extra-offset (pair of numbers):

pair of reals (a cons) forcing an extra offset before outputting. extra-offset is added just before `printing' the grob, so the typesetting engine is completely oblivious to it.

Default value: (unset)

interfaces (list):

list of symbols indicating the interfaces supported by this object. Is initialized from the meta field. Default value: (unset)

dependencies (list):

list of score-grob pointers that indicate who to compute first for certain global passes. Default value: (unset)

no-spacing-rods (boolean):

read from grobs: boolean that makes Separation_item ignore this item (MOVE ME TO ITEM). Default value: (unset)

extra-extent-X (pair of numbers):

enlarge in X dimension by this much, measured in staff space. Default value: (unset)

extra-extent-Y (pair of numbers):

see extra-extent-Y. Default value: (unset)

minimum-extent-X (pair of numbers):

minimum size in X dimension, measured in staff space. Default value: (unset)

minimum-extent-Y (pair of numbers):

see minimum-extent-Y. Default value: (unset)

origin (input location):

location in input file of the definition. Default value: (unset)

transparent (boolean):

This is almost the same as setting molecule-callback to #f, but this retains the dimensions of this grob, which means that you can erase grobs individually. . Default value: (unset)
