3.1.84 PhrasingSlur

PhrasingSlur objects are created by: Phrasing_slur_engraver.

Standard settings:

control-points (list):

ly:slur::calc-control-points

List of offsets (number pairs) that form control points for the tie, slur, or bracket shape. For Béziers, this should list the control points of a third-order Bézier curve.

details (list):

'((region-size . 4) (head-encompass-penalty . 1000.0) (stem-encompass-penalty . 30.0) (edge-attraction-factor . 4) (same-slope-penalty . 20) (steeper-slope-factor . 50) (non-horizontal-penalty . 15) (max-slope . 1.1) (max-slope-factor . 10) (free-head-distance . 0.3) (free-slur-distance . 0.8) (extra-object-collision-penalty . 50) (accidental-collision . 3) (extra-encompass-free-distance . 0.3) (extra-encompass-collision-distance . 0.8) (head-slur-distance-max-ratio . 3) (head-slur-distance-factor . 10) (absolute-closeness-measure . 0.3) (edge-slope-exponent . 1.7) (close-to-edge-length . 2.5) (encompass-object-range-overshoot . 0.5) (slur-tie-extrema-min-distance . 0.2) (slur-tie-extrema-min-distance-penalty . 2))

Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a details property.

direction (direction):

ly:slur::calc-direction

If side-axis is 0 (or X), then this property determines whether the object is placed LEFT, CENTER or RIGHT with respect to the other object. Otherwise, it determines whether the object is placed UP, CENTER or DOWN. Numerical values may also be used: UP=1, DOWN=-1, LEFT=-1, RIGHT=1, CENTER=0.

height-limit (dimension, in staff space):

2.0

Maximum slur height: The longer the slur, the closer it is to this height.

minimum-length (dimension, in staff space):

1.5

Try to make a spanner at least this long, normally in the horizontal direction. This requires an appropriate callback for the springs-and-rods property. If added to a Tie, this sets the minimum distance between noteheads.

ratio (number):

0.333

Parameter for slur shape. The higher this number, the quicker the slur attains its height-limit.

spanner-id (string):

""

An identifier to distinguish concurrent spanners.

springs-and-rods (boolean):

ly:spanner::set-spacing-rods

Dummy variable for triggering spacing routines.

stencil (stencil):

ly:slur::print

The symbol to print.

thickness (number):

1.1

Line thickness, generally measured in line-thickness.

vertical-skylines (pair of skylines):

ly:slur::vertical-skylines

Two skylines, one above and one below this grob.

Y-extent (pair of numbers):

ly:slur::height

Hard coded extent in Y direction.

This object supports the following interface(s): grob-interface, slur-interface and spanner-interface.
