我想在使用 SVG 的 animateMotion 标签设置动画的路径上应用旋转。 似乎应用于 animateMotion 标记遵循的路径的规则 transform-origin:50%;transform: rotate(240deg); 不会改变动画。
<path id="theMotionPathIdLikeToRotate" d="m 100,100 -3e-6,-52.916668 45.82718,26.458333 0,52.916665" stroke-width="5px" stroke="aqua" fill="none" style="transform-origin:50%;transform: rotate(120deg);" stroke-linecap="round" stroke-linejoin="round" />
我的目标是创建动画并重复变换。 In this example 我想创建其他移动的圆圈,围绕六边形中心旋转 120 度和 240 度。
最佳答案
仅由 d
引用的路径的路径定义 ( <mpath>
)元素被使用。任何transform
它可能会被忽略。
您需要将变换应用于圆和 <mpath>
在一起。
