relativeCubicTo method

void relativeCubicTo (double x1, double y1, double x2, double y2, double x3, double y3)

Adds a cubic bezier segment that curves from the current point to the point at the offset (x3,y3) from the current point, using the control points at the offsets (x1,y1) and (x2,y2) from the current point.

Implementation 

void relativeCubicTo(double x1, double y1, double x2, double y2, double x3, double y3) native 'Path_relativeCubicTo';
