att.curvature

Attributes that describe curvature.
Module
MEI.shared
Attributes
@bezier, @bulge, @curvedir
@bezier(optional)Records the placement of Bezier control points as a series of pairs of space-separated values; e.g., 19 45 -32 118. One or more values, each consisting of a sequence of decimal and decimal sub-values.
<att.curvature>direct children@bezier
@bulge(optional)Describes a curve as one or more pairs of values with respect to an imaginary line connecting the starting and ending points of the curve. The first value captures a distance to the left (positive value) or right (negative value) of the line, expressed in virtual units. The second value of each pair represents a point along the line, expressed as a percentage of the line’s length. N.B. An MEI virtual unit (vu) is half the distance between adjacent staff lines where the interline space is measured from the middle of a staff line. One or more of decimal.
<att.curvature>direct children@bulge
@curvedir(optional)Describes a curve with a generic term indicating the direction of curvature. Allowed values are: "above" (Upward curve.), "below" (Downward curve.), "mixed" (A "meandering" curve, both above and below the items it pertains to.)
