ImagickDraw::pathCurveToRelative — Draws a cubic Bezier curve
$x1,$y1,$x2,$y2,$x,$y本函数还未编写文档，仅有参数列表。
Draws a cubic Bezier curve from the current point to (x,y) using (x1,y1) as the control point at the beginning of the curve and (x2,y2) as the control point at the end of the curve using relative coordinates. At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier.
x1x coordinate of starting control point
y1y coordinate of starting control point
x2x coordinate of ending control point
y2y coordinate of ending control point
xending x coordinate
yending y coordinate
