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.

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.

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.)*
