svg动画
=====

为svg组件添加动画效果。

#### 属性样式动画

在svg的子组件[animate](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-components-svg-animate)中，通过attributeName设置需要进行动效的属性，from设置开始值，to设置结束值。

<!-- xxx.hml -->
<div class="container">
  <svg>
    <text x="300" y="300" fill="blue">
      Hello
      <animate attributeName="font-size" from="30" to="60" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="fill" from="red" to="blue" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="opacity" from="1" to="0.3" dur="3s" repeatCount="indefinite">
      </animate>
    </text>
    <text x="300" y="600" fill="blue">
      World
      <animate attributeName="font-size" from="30" to="60" values="30;80" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="fill" from="red" to="blue"  dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="opacity" from="0.3" to="1" dur="3s" repeatCount="indefinite">
      </animate>
    </text>
  </svg>
</div>

在设置动画变化值时，如果已经设置了values属性，则from和to都失效。

#### 路径动画

在svg的子组件[animateMotion](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-components-svg-animatemotion)中，通过path设置动画变化的路径。

<!-- xxx.hml -->
<div class="container">
  <svg fill="white" width="800" height="900">
    <path d="M300,200 h-150 a150 150 0 1 0 150 -150 z" fill="white" stroke="blue" stroke-width="5" >
    </path>
    <path fill="red" d="M-5,-5 L10,0 L-5,5 L0,0 Z"  >
      <animateMotion dur="2000" repeatCount="indefinite" rotate="auto-reverse"path="M300,200 h-150 a150 150 0 1 0 150 -150 z">
      </animateMotion>
    </path>
  </svg>
</div>

#### animateTransform动画

在svg的子组件[animateTransform](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-components-svg-animatetransform)中，通过attributeName绑定transform属性，type设置动画类型，from设置开始值，to设置结束值。

<!-- xxx.hml -->
<div class="container" style="">

    <line x1="90" y1="300" x2="90" y2="730" stroke-width="10" stroke="black" stroke-linecap="round">

      fill="freeze">

    <circle cx="500" cy="500" r="50" stroke-width="15" fill="red" stroke="#e70d0d">

    <line x1="650" y1="300" x2="650" y2="600" stroke-width="20" stroke="blue" stroke-linecap="round">
