为 Raphael 元素及其一组发光路径设置动画

Question

这个answer has been accepted 但它不起作用，因为glowSet.animate({cx: 100}) 不会像圆圈一样移动光晕。此外，要为焕发集路径对象设置动画，您需要应用 a transformation, something like this，但一个简单的移动转换会将辉光路径缩小到 0。

目前的方法是js fiddle，还是有更聪明的方法来实现同样的目标？：

paper = Raphael(0, 0, 200, 200);
circle = paper.circle(10, 10, 10);
glow = circle.glow();
glow.push(circle);
all = glow;
all.attr("stroke", "#f00");

// Animation
delay = 300
speed = 1000

// Will only animate the glow paths and not the circle
// Also shrinks the glow paths to nothing.
_transformedPath = Raphael.transformPath('M100 100');
animGlow = Raphael.animation({path: _transformedPath}, speed);
all.animate(animGlow.delay(delay + 200));

//We shouldn't want or need to do this.  You can apply an
//element.matrix.translate(x, y), followed by a //element.transform(element.matrix.toTransformString()) for 
//each of the elements in the glowSet
anim = Raphael.animation({cx: 100, cy: 100}, speed);
circle.animate(anim.delay(delay));

Answer 1

对于动画，您只需要使用translate 而不是matrix，对于transform：

// Animation
delay = 300
speed = 1000

_transformedPath = Raphael.transformPath('t100 100');
animGlow = Raphael.animation({transform: _transformedPath}, speed, '<>');
all.animate(animGlow.delay(delay));
