ImagickDraw::pathCurveToQuadraticBezierRelative — Draws a quadratic Bezier curve
$x1,$y1,$x,$y本函數還未編寫(xiě)文檔，僅有參數列表。
Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point using relative coordinates. At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier.
x1starting x coordinate
y1starting y coordinate
xending x coordinate
