text-spanner-interface

generic text spanner

User settable properties:

bound-padding (number)

The amount of padding to insert around spanner bounds.

bracket-flare (pair of numbers)

A pair of numbers specifying how much edges of brackets should slant outward. Value 0.0 means straight edges

dash-fraction (number)

Size of the dashes, relative to dash-period. Should be between 0.0 (no line) and 1.0 (continuous line).

dash-period (number)

the length of one dash + white space. If negative, no line is drawn at all.

edge-height (pair)

A pair of number specifying the heights of the vertical edges '(left-height . right-height).

edge-text (pair)

A pair specifying the texts to be set at the edges '(left-text . right-text).

enclose-bounds (number)

How much of the bound a spanner should enclose: +1 = completely, 0 = center, -1 not at all.

shorten-pair (pair of numbers)

The lengths to shorten a text-spanner on both sides, for example a pedal bracket. Positive values shorten the text-spanner, while negative values lengthen it.

style (symbol)

This setting determines in what style a grob is typeset. Valid choices depend on the stencil callback reading this property.

thickness (number)

Line thickness, generally measured in line-thickness.

This grob interface is used in the following graphical objects: SustainPedal, TextSpanner and TrillSpanner
