att.curvature

att.curvature Attributes that describe curvature.
Module MEI.shared
Members
curve (direct member of att.curvature)
att.phrase.vis.cmn (no elements directly inheriting from this class)
Attributes
@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
@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. One or more of decimal. att.curvature
@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.) att.curvature
