PquadraticVertex
processingSpecifies vertex coordinates for quadratic Bezier curves. Each call to PquadraticVertex
defines the position of one control point and one anchor point of a Bezier curve, adding a new segment to a line or shape. The first time PquadraticVertex
is used within a PbeginShape
call, it must be prefaced with a call to Pvertex
to set the first anchor point. This function must be used between PbeginShape
and PendShape
and only when there is no MODE parameter specified to PbeginShape
.
