Hairpin

Hairpin grobs are created by: Dynamic_engraver

dynamic-interface

Any kind of loudness sign

hairpin-interface

hairpin crescendo.

padding - horizontal padding. This is useful if a crescendo is set next to a text like `mf'

grow-direction (direction):

crescendo or decrescendo?. Default value: (unset)

thickness (number):

thickness, measured in stafflinethickness. Default value: 1.0

height (number):

in staffspace. Default value: 0.6666

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: '(#<primitive-procedure Side_position_interface::aligned_on_self>)

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 Hairpin::brew_molecule>

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)
