svg 图标在网页上锯齿状明显

[i8k]

一直以为矢量图是很平滑的，没想到放在网页中，锯齿感明显。请问是什么原因？如何修复？

import React from 'react';

interface VoiceIconProps {
  color?: string;
  className?: string;
  size?: number | string;
}

const VoiceIcon: React.FC<VoiceIconProps> = ({ 
  color = '#000000', 
  className = '',
  size = 24
}) => {
  return (
    <svg 
      xmlns="http://www.w3.org/2000/svg" 
      width={size} 
      height={size} 
      viewBox="0 0 24 24"
      className={className}
      style={{ color }}
    >
      <style>
        {`
          .audio-arc {
            fill: none;
            stroke-width: 2;
            stroke-linecap: round;
          }
          
          #inner {
            stroke: none;
          }
        `}
      </style>
      
      <g transform="translate(6, 12) rotate(-45)">
        <path id="inner" d="M0,0 L3,0 A3,3 0 0 1 0,3 Z" fill={color}/>
        <path id="middle" className="audio-arc" d="M6,0 A6,6 0 0 1 0,6" stroke={color} />
        <path id="outer" className="audio-arc" d="M9.5,0 A9.5,9.5 0 0 1 0,9.5" stroke={color}/>
      </g>
    </svg>
  );
};

export default VoiceIcon;

唉，解决办法就是画精细一点：
```javascript
import React from 'react';

interface VoiceIconProps {
color?: string;
className?: string;
size?: number | string;
}

const VoiceIcon: React.FC<VoiceIconProps> = ({
color = '#000000',
className = '',
size = 24
}) => {
return (
<svg
xmlns="http://www.w3.org/2000/svg"
width={size}
height={size}
viewBox="0 0 100 100"
className={className}
style={{ color }}
>

};

export default VoiceIcon;

不用 stroke color ，用 fill color 会好一些
