在 SVG 路径动画中为 SVG 设置动画

Question

我已经建立了一个路径动画，但是我在 svg 中的锯片有问题。

我想为 Sawblade 制作动画（旋转 360 度）。

    <style>html {
  background-color: #337ab7;
}

.cutline {
  stroke: #222;
  stroke-width: .1%;
  stroke-width: .5%;
  stroke-dasharray: 1% 2%;
  stroke-linecap: round;
  fill: none;
}

.sawblade {
  fill: #eee;
  width: 200px;
  height: auto;
  margin: 30px;
}
</style>
<svg viewBox="0 0 3387 1270">
  <path id="cutline" class="cutline" d="M 2700 1000 L 100 1000 " />

你能帮帮我吗？

Answer 1

您可以将两个动画都放在需要动画的元素中。我正在使用<animateTransform> 旋转锯片，使用<animateMotion> 在路径上移动锯片。或者，您可以在这里翻译形状。

我稍微改变了路径，因为我想消除translate。实际上，我使用了这个工具：Lea Verou 的Convert SVG path to all-relative or all-absolute 将路径更改为小写命令。接下来，我将路径的起点修改为用于翻译的数量。

html {
  background-color: #337ab7;
}

.cutline {
  stroke: #222;
  stroke-width: .1%;
  stroke-width: .5%;
  stroke-dasharray: 1% 2%;
  stroke-linecap: round;
  fill: none;
}

.sawblade {
  fill: #eee;
  width: 200px;
  height: auto;
  margin: 30px;
}
