需要填充Svg动画的曲线

Question

我在svg中有一条曲线需要在悬停时沿着它的路径填充曲线任何人都可以帮忙吗？填充动画应该是另一种颜色或可以是相同的。我尝试使用animate标签，但它没有效果，并且像任何东西一样填充。我的SVG路径如下。这是我的Svg代码，需要将此路径填充为dashoffset。

<svg width="210mm" height="45mm" viewBox="0 0 744.09449 159.44881">
    <path style="opacity:1;fill:#ded9d5;fill-opacity:1;fill-rule:nonzero;stroke:none;stroke-width:0;stroke-linecap:round;stroke-linejoin:bevel;stroke-miterlimit:4;stroke-opacity:1"

Answer 1

您的SVG补丁代码超出了用户viewport，因此无法看到曲线 我使用 - svg-editor Peter Collingridge

稍微优化了您的SVG代码

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" 
 width="420" height="180" viewBox="-50 540 372 80.4" >
<path id="path1" d="m18.9 529.4c1.1 2.2 1.7 4.6 1.7 7.1 0 2.4-0.6 4.8-1.7 6.9l36.9 0c17.1 0 11.1 14.8 13.5 34.9 7.3 27.3 35.9 38.1 62.6 41.7-1.5-2.4-4.3-7.9-4.3-10.9 0-3.1 0.9-5.7 2.7-8.3-23.3-1.1-29.9-7.3-39.3-22.3-4.8-11.4 5.7-49.2-28.7-49.2z"  style=" stroke:none; stroke-width:1; fill:#ded9d5; />  
</svg> 

您的代码绘制了一个封闭的路径，因此使用stroke-dashoffset属性的动画将沿着封闭的路径绘制曲线。

以下示例。动画的开头是将鼠标悬停在形状上方。

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" 
 width="420" height="180" viewBox="-50 540 372 80.4" >
  
  <path id="path1" d="m18.9 529.4c1.1 2.2 1.7 4.6 1.7 7.1 0 2.4-0.6 4.8-1.7 6.9l36.9 0c17.1 0 11.1 14.8 13.5 34.9 7.3 27.3 35.9 38.1 62.6 41.7-1.5-2.4-4.3-7.9-4.3-10.9 0-3.1 0.9-5.7 2.7-8.3-23.3-1.1-29.9-7.3-39.3-22.3-4.8-11.4 5.7-49.2-28.7-49.2z"  
  style=" stroke:#4B0082; stroke-width:3; fill:#ded9d5; stroke-dasharray:571; stroke-dashoffset:571;">
  <animate id="dash" attributeName="stroke-dashoffset" values="571;0;571" begin="path1.mouseover" restart="whenNotActive" dur="5s" fill="freeze" repeatCount="1"></animate>
  </path>
</svg>     

begin="path1.mouseover" - 启动动画的命令，其中path1是路径标识符

restart="whenNotActive" - 防止重新动画

values="571;0;571" - 从571px到零并返回

的路径上的动画

如果我正确理解了问题的作者，则不需要动画路径，而是用path填充由颜色构成的整个图形。

当路径未关闭时，很容易做到这一点 - 将线条的粗细增加到所需的值并使用动画stroke-dashoffset

要解决这些矛盾，您可以使用此技术：在矢量编辑器中打开我们的代码，并在图中间绘制一条额外的曲线。

这条线将会动画。要开始动画，请移动光标。

<svg id="svg2" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" width="420" height="180" viewBox="-50 550 372 80.4"  version="1.1">
  <path d="m18.9 529.4c1.1 2.2 1.7 4.6 1.7 7.1 0 2.4-0.6 4.8-1.7 6.9l36.9 0c17.1 0 11.1 14.8 13.5 34.9 7.3 27.3 35.9 38.1 62.6 41.7-1.5-2.4-4.3-7.9-4.3-10.9 0-3.1 0.9-5.7 2.7-8.3-23.3-1.1-29.9-7.3-39.3-22.3-4.8-11.4 5.7-49.2-28.7-49.2z"  
  style="fill:#F8F3EF;stroke-width:1; stroke:none;" />
     
  <path style="stroke-dasharray:152;stroke-dashoffset:152; fill:none;stroke-width:2;stroke:yellowgreen;"
  d="m20.8 535.9c24.9 2.5 55.9-6.4 57.2 15.4 3.5 19.3-1.6 31.7 14 45.2 21.1 17.5 35.4 13 35.4 13">
  <animate id="dash" attributeName="stroke-dashoffset" values="152;0" begin="svg2.mouseover" restart="whenNotActive" dur="3s"    fill="freeze" repeatCount="1">
  </animate>

	</path>
</svg>   

接下来，增加线条的粗细 - stroke-width: 20;并获得所需的结果：

<svg id="svg2" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" width="420" height="180" viewBox="-50 550 372 80.4"  version="1.1">

  style="fill:#F8F3EF;stroke-width:1; stroke:none;" />
  
    
  <path style="stroke-dasharray:152;stroke-dashoffset:152; fill:none;stroke-width:20;stroke:yellowgreen;"
  d="m20.8 535.9c24.9 2.5 55.9-6.4 57.2 15.4 3.5 19.3-1.6 31.7 14 45.2 21.1 17.5 35.4 13 35.4 13">
  <animate id="dash" attributeName="stroke-dashoffset" values="152;0" begin="svg2.mouseover" restart="whenNotActive" dur="3s"    fill="freeze" repeatCount="1">
  </animate>

	</path>
</svg>   

使用filter

的解决方案

启动解决方案的想法 - SVG Filter tag on hover @Holger Will

通过更改过滤器dx的属性 - 沿X轴偏移来实现填充路径的动画。

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" 
 width="420" height="180" viewBox="-50 540 372 80.4">
   <defs>
    <filter id="violet-fill" x="0%" y="0%">
      <feFlood flood-color="#F8F3EF" />
      <feOffset dx="0">
        <animate id="anim" attributeName="dx" values="0;115;0" dur="5s" begin="path1.mouseover" restart="whenNotActive" fill="freeze"/> 
      </feOffset>
      <feComposite operator="in" in2="SourceGraphic" />
      <feComposite operator="over" in2="SourceGraphic" />
    </filter>
  </defs>
  <style>
  path {
  filter: url(#violet-fill);
}
  </style>
  <path id="path1" d="m18.9 529.4c1.1 2.2 1.7 4.6 1.7 7.1 0 2.4-0.6 4.8-1.7 6.9l36.9 0c17.1 0 11.1 14.8 13.5 34.9 7.3 27.3 35.9 38.1 62.6 41.7-1.5-2.4-4.3-7.9-4.3-10.9 0-3.1 0.9-5.7 2.7-8.3-23.3-1.1-29.9-7.3-39.3-22.3-4.8-11.4 5.7-49.2-28.7-49.2z"

Answer 2

我会添加一个类而不是ID，并在类上使用CSS“：hover”。

或者你可以同时拥有两者。

这是交互式svg的绝佳网页。 Mouseover effects in SVGs

示例代码，必须删除svg中的硬编码样式才能使css生效。

.effective{
fill:red;
}

.effective:hover{
fill:black;
 transition: fill 2s ease-in;
}
