3.1.90 Slur

Slur objects are created by: Slur_engraver.

Standard settings:

control-points (list):


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.

direction (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.

springs-and-rods (boolean):


Dummy variable for triggering spacing routines.

Y-extent (pair of numbers):


Hard coded extent in Y direction.

stencil (unknown):


The symbol to print.

thickness (number):


Line thickness, generally measured in line-thickness.

line-thickness (number):


The thickness of the tie or slur contour.

minimum-length (dimension, in staff space):


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.

height-limit (dimension, in staff space):


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

ratio (number):


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

avoid-slur (symbol):


Method of handling slur collisions. Choices are around, inside, outside. If unset, scripts and slurs ignore each other. around only moves the script if there is a collision; outside always moves the script.

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