javascript - svg 变形而不翻转

Question

我一直在尝试找到一种简单且自由的方法来在贝塞尔曲线形状与其镜像副本之间进行变形。因为他们的点数相同，所以我认为这将是一件容易的事。事实并非如此。我尝试了 KUTE 和 SVG morpheus。 Kute 执行了不必要的垂直翻转，Morpheus 执行了不必要的水平翻转 ( codepen here )。唯一能做到这一点的 javascript 库是付费的 MorphSVG 插件。 (codepen here) 很遗憾，我希望将来能找到更便宜的解决方案。如果有人知道任何事情，请告诉我。

 var svgMorpheus = new SVGMorpheus('#icon', {rotation: "none"});
 var icons = ['question', 'answer'];
 var current = 0;

基于我的旧动画的快速破解:http://jsfiddle.net/alkhoo/JwkYm/11/ - 鼠标悬停即可激事件画。

注意:greensock 动画包含 paths 值。

 $(function () {

     //Grab an array of all the main SVG Elements
     var containers = $(".category .item a");

     //Define some vars that we will use later
     var speed = 1000;
     var animation = mina.backout;

     //Loop through all of these containers and insert the SVG's
     containers.each(function (index) {

         //Get each of our SVG tags
         var s = Snap(".animated-overlay.svg-" + index);

         //Define our Paths

         var defaultWhitePath = "M1.8978756799999998,64.59785067199999 C4.5919579200000005,94.29202528 74.7848272,99.01918832 128.25879712,95.43520928 361.0060832,78.08572735999999 468.2360832,8.157339040000004 562.54879712,6.478409280000005 646.3748272,4.004430240000005 663.93195792,95.19048896 664.08987568,93.45505007999999 664.24724128,114.2054704 664.1263182399999,144.17150224 664.1263182399999,166.67625712 443.1668704,166.67625712 222.2168704,166.67625712 1.26631824,166.67625712 1.26631824,165.36156416 -0.8027587199999999,36.217596 1.8898756799999998,64.59746416 z";
