我正在尝试向通过SVG的剪切路径剪切的图像添加阴影,如何在 React native 中完成? 如果我的原始SVG有阴影,则图像会覆盖它。 我当前的代码:
<svg>
<Defs>
<ClipPath id='clip'>
<Path
d='M113.093,63.183c9.5-23.17,42.313-23.17,51.814,0l97.257,237.195A28,28,0,0,1,236.257,339H41.743a28,28,0,0,1-25.907-38.622Z'
transform='translate(340.5 -12.21) rotate(90)'
scale={scale}
/>
</ClipPath>
</Defs>
<Image
href={{
uri: uri,
}}
clipPath='url(#clip)'
width='100%'
height='100%'
preserveAspectRatio='xMidYMax slice'
/>
</Svg>
谢谢, 埃雷兹(Erez)

如果将阴影应用于图像,然后剪切图像,则还将剪切阴影。在下一个示例中,我将使用路径并将阴影应用于路径。接下来,我要绘制图像并裁剪图像。
svg{width:300px;}
<svg viewBox="150 -20 180 160" width="200">
<defs>
<filter id="f">
<feGaussianBlur in="SourceAlpha" stdDeviation="5" result="desenfoque"></feGaussianBlur>
<feOffset in="desenfoque" dx="3" dy="3" result="sombra"></feOffset>
<feMerge>
<feMergeNode in="sombra"></feMergeNode>
<feMergeNode in="SourceGraphic"></feMergeNode>
</feMerge>
</filter>
<clipPath id='clip'>
<path id="thePath" d='M113.093,63.183c9.5-23.17,42.313-23.17,51.814,0l97.257,237.195A28,28,0,0,1,236.257,339H41.743a28,28,0,0,1-25.907-38.622Z' transform='translate(340.5 -12.21) rotate(90) scale(.5)'/>
</clipPath>
</defs>
<use xlink:href="#thePath" filter="url(#f)" id="use" />
<image x="150" y="-20" xlink:href="https://assets.codepen.io/222579/castell.jpg" clip-path='url(#clip)' width='100%' height='100%' preserveAspectRatio='xMidYMax slice' />
</svg>
OP正在评论:
我正在使用带有“ react-native-svg”库的本地响应。该代码在这种情况下似乎不起作用。缺乏“ feGaussianBlur”和其他组件的支持
在这种情况下,如果只有这种形状,则可以使用CSS滤镜将阴影应用于svg元素:
svg{filter:drop-shadow(2px 2px 5px #000);}
<svg viewBox="150 -20 180 160" width="200">
<defs>
<clipPath id='clip'>
<path id="thePath" d='M113.093,63.183c9.5-23.17,42.313-23.17,51.814,0l97.257,237.195A28,28,0,0,1,236.257,339H41.743a28,28,0,0,1-25.907-38.622Z' transform='translate(340.5 -12.21) rotate(90) scale(.5)'/>
</clipPath>
</defs>
<image x="150" y="-20" xlink:href="https://assets.codepen.io/222579/castell.jpg" clip-path='url(#clip)' width='100%' height='100%' preserveAspectRatio='xMidYMax slice' />
