public final class DrawCurve
extends Operation

'Append a cubic Bezier curve to the current path' operation [PDF:1.6:4.4.1].

Such curves are defined by four points: two endpoints (the current point and the final point) and two control points (the first control point, associated to the current point, and the second control point, associated to the final point).

Field Summary

static String	FinalOperator Specifies only the second control point (the first control point coincides with the initial point of the curve).
static String	FullOperator Specifies both control points explicitly.
static String	InitialOperator Specifies only the first control point (the second control point coincides with the final point of the curve).
