### 3.1.112 StrokeFinger

StrokeFinger objects are created by: New_fingering_engraver.

Standard settings:

> `digit-names` (vector):

>   `#(p i m a x)`

>   Names for string finger digits.

> `font-shape` (symbol):

>   `'italic`

>   Select the shape of a font. Choices include `upright`, `italic`, `caps`.

> `font-size` (number):

>   `-4`

>   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. Fractional values are allowed.

> `padding` (dimension, in staff space):

>   `0.5`

>   Add this much extra space between objects that are next to each other.

> `script-priority` (number):

>   `100`

>   A key for determining the order of scripts in a stack, by being added to the position of the script in the user input, the sum being the overall priority. Smaller means closer to the head.

> `self-alignment-X` (number):

>   `0`

>   Specify alignment of an object. The value `-1` means left aligned, `0` centered, and `1` right-aligned in X direction. Other numerical values may also be specified.

> `self-alignment-Y` (number):

>   `0`

>   Like `self-alignment-X` but for the Y axis.

> `staff-padding` (dimension, in staff space):

>   `0.5`

>   Maintain this much space between reference points and the staff. Its effect is to align objects of differing sizes (like the dynamics p and f) on their baselines.

> `stencil` (stencil):

>   `ly:text-interface::print`

>   The symbol to print.

> `text` (markup):

>   `stroke-finger::calc-text`

>   Text markup. See Formatting text.

> `Y-extent` (pair of numbers):

>   `#<unpure-pure-container #<primitive-procedure ly:grob::stencil-height> >`

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