Question

我有一个包含多个路径的SVG，我试图为其填充动画。我的目标是制作一个动画，从底部到顶部慢慢填充颜色，每条路径都有不同的颜色。

我尝试过使用lineargradient，但无法弄清楚如何将它与路径一起使用。

我创建了以下SVG：

    <?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 19.0.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     viewBox="0 0 148 148" style="enable-background:new 0 0 148 148;" xml:space="preserve">
<style type="text/css">
    .st0{fill:#0000FF;stroke:#000000;stroke-miterlimit:10;}
    .st1{fill:#FF00FF;stroke:#000000;stroke-miterlimit:10;}
</style>
<g id="XMLID_1_">
    <path id="XMLID_4_" class="st0" d="M147.4,71.3L0.8,67.3c-0.2,2.2-0.3,4.4-0.3,6.7c0,40.6,32.9,73.5,73.5,73.5s73.5-32.9,73.5-73.5
        C147.5,73.1,147.5,72.2,147.4,71.3z"/>
    <path id="XMLID_3_" class="st1" d="M74,0.5C35.7,0.5,4.2,29.8,0.8,67.3l146.6,4.1C146.1,32,113.7,0.5,74,0.5z"/>
</g>
</svg>

所以蓝色会慢慢从底部到顶部填充，然后粉红色也会从下到上开始。

**编辑：我发现了以下示例 - 但如上所述，我有路径，所以如果可能的话需要解决这个问题

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100" width="200" height="200">
      <linearGradient id="lg" x1="0.5" y1="1" x2="0.5" y2="0">
          <stop offset="0%" stop-opacity="1" stop-color="royalblue"/>
          <stop offset="40%" stop-opacity="1" stop-color="royalblue">
            <animate attributeName="offset" values="0;1;0" repeatCount="indefinite" dur="10s" begin="0s"/>
          </stop>
          <stop offset="40%" stop-opacity="0" stop-color="royalblue">
            <animate attributeName="offset" values="0;1;0" repeatCount="indefinite" dur="10s"  begin="0s"/>
          </stop>
          <stop offset="100%" stop-opacity="0" stop-color="royalblue"/>
      </linearGradient>
      <circle cx="50" cy="50" r="45" fill="url(#lg)" stroke="crimson" stroke-width="5"/>
</svg>

谢谢。

对于那些感兴趣的人，我找到了解决方案（不确定这是否是最干净的方式，但从来没有这样做过。）

**注意：SVG路径有点混乱（我不想清理它）但动画代码无论如何都是一样的。
