paper.js关闭路径之间的变形/补间

Question

我想将一条路径设置为另一条路径（将黑色形状转换为红色SVG形状 - 最终都是黑色）：

var circlePath = new paper.Path.Circle(centerPoint, 90);
circlePath.fillColor = 'red';
circlePath.fullySelected = true;

var winkData = 'M-184.4,393.4c0,0-0.5-0.5-1.4-1.4c-0.9-0.9-2.2-2.1-4-3.3c-1.8-1.3-4.1-2.4-6.8-3.4c-1.4-0.4-2.8-0.9-4.3-1

var winkPath = new paper.Path(winkData);
winkPath.fillColor = 'black';
winkPath.scale(4);
winkPath.simplify(2)
winkPath.fullySelected = true;
winkPath.position = centerPoint

paper.view.draw();

有没有人有关于如何做到这一点的建议？
