SVG 笔划未显示在 clipPath 内部
SVG stroke not showing inside of clipPath
我有以下 Codepen,我在其中尝试为图像周围的圆圈设置动画。
到目前为止,我有一个正在裁剪图像的圆形 SVG,但它没有在 clipPath 中显示笔画。
如何显示边框?
class App extends React.Component {
render() {
return (
<svg width='48' height='48'>
<defs>
<clipPath id='circleView'>
<circle cx='24' cy='24' r='23' fill='none' stroke='red' strokeWidth='2' />
</clipPath>
</defs>
<image width='48' height='48' xlinkHref={'https://source.unsplash.com/random'} clipPath='url(#circleView)' />
</svg>
)
}
}
正如罗伯特所说,clip-path
行中的子 SVG 图形未显示。
因此,对于动画,您需要在 clip-path
之外添加另一个圆圈
<circle cx="25" cy="24" r="14" fill="none" stroke="red" strokeWidth="2" />
.container {
width:25%;
height:25%;
}
<div class="container">
<svg viewBox="0 0 48 48" >
<defs>
<clipPath id='circleView'>
<circle cx='24' cy='22' r='16' fill='none' stroke='red' stroke-width='2' />
</clipPath>
</defs>
<image width="100%" height="100%" xlink:href='https://i.stack.imgur.com/O9eO8.jpg'
clip-path='url(#circleView)' />
<circle cx='24' cy='22' r='16' fill='none' stroke='red' strokeWidth='2' />
</svg>
</div>
要为圆圈设置动画,请使用 stroke-dashoffset
属性中从最大值到零的更改。 values="(100.48;0)"
点击后开始动画
.container {
width:25%;
height:25%;
}
<div class="container">
<svg id="svg1" viewBox="0 0 48 48">
<defs>
<clipPath id='circleView'>
<circle cx='24' cy='22' r='16' fill='none' stroke='red' stroke-width='2' />
</clipPath>
</defs>
<image width="100%" height="100%" xlink:href='https://i.stack.imgur.com/O9eO8.jpg' clip-path='url(#circleView)' />
<circle transform="rotate(-90 24 22)" cx="24" cy="22" r="16" fill='none' stroke='red' strokeWidth='2'
stroke-dasharray="100.48" stroke-dashoffset="100.48" >
<animate
attributeName="stroke-dashoffset"
dur="1s"
begin="svg1.click"
values="100.48;0"
fill="freeze"/>
</circle>
</svg>
</div>
带有 CSS
的动画变体
我在圆形动画中添加了透明动画。
鼠标悬停时动画开始。
.container {
width:25%;
height:25%;
}
#crc1 {
fill:skyblue;
stroke-width:1;
stroke:red;
stroke-dasharray:100.48;
stroke-dashoffset:100.48;
fill-opacity:0.9;
}
#crc1:hover {
animation: dash 1.5s ease-out forwards;
}
@keyframes dash {
0% { stroke-dashoffset: 100.48; fill-opacity:0.9; }
50% { fill-opacity:0.45;}
100% { stroke-dashoffset: 0; fill-opacity:0; }
}

clip-path: url(#circleView);
