bool ImagickDraw::pathEllipticArcRelative ( float $rx, float $ry, float $x_axis_rotation, bool $large_arc_flag, bool $sweep_flag, float $x, float $y )
Draws an elliptical arc from the current point to (x, y) using relative coordinates. The size and orientation of the ellipse are defined by two radii (rx, ry) and an xAxisRotation, which indicates how the ellipse as a whole is rotat
