我有一个瓶子的图像,并尝试用某种颜色填充这个瓶子

我找到了填充坐标,但瓶子内的背景未填充

.item {
  width: 150px;
  height: 150px;
}

#tubeLiquid {
  background-color: #74ccf4;
  clip-path: polygon(45% 19%, 41% 22%, 41% 29%, 41% 36%, 41% 43%, 41% 50%, 41% 57%, 41% 63%, 41% 70%, 41% 77%, 41% 83%, 41% 90%, 43% 93%, 50% 92%, 56% 93%, 60% 88%, 59% 81%, 60% 75%, 60% 68%, 60% 61%, 59% 55%, 59% 48%, 59% 42%, 59% 35%, 59% 29%, 58% 23%, 54% 19%);
}

#bottleMask{
  background-color: #FFFFFF;
  clip-path: polygon(45% 19%, 41% 22%, 41% 29%, 41% 36%, 41% 43%, 41% 50%, 41% 57%, 41% 63%, 41% 70%, 41% 77%, 41% 83%, 41% 90%, 43% 93%, 50% 92%, 56% 93%, 60% 88%, 59% 81%, 60% 75%, 60% 68%, 60% 61%, 59% 55%, 59% 48%, 59% 42%, 59% 35%, 59% 29%, 58% 23%, 54% 19%);
}
<div class="item">

您不需要额外的
由于瓶子的形状,您可以使用圆形 作为剪辑路径:

waterLevel.addEventListener('input', e => {
  let value = +e.currentTarget.value
  tubeLiquid.setAttribute('stroke-dasharray', `${value} 100`)
})
svg {
  width: 20%;
}
<h3>Draw clip-path</h3>
<svg viewBox="0 0 300 300">
    <image width="300" href="https://i.ibb.co/Mhfwtxp/image-removebg-preview-1.png" />
    <!-- test clip path -->
    <rect x="115" y="55" width="69" height="235" rx="20" ry="20" fill="red" />
  </svg>

<h3>Draw liquid fill</h3>
<svg viewBox="0 0 300 300">
    <image width="300" href="https://i.ibb.co/Mhfwtxp/image-removebg-preview-1.png" />
    <line x1="149.5" y1="290" x2="149.5" y2="50" stroke="green" stroke-width="70" />
  </svg>

<h3>Apply clip path</h3>
<p><input type="range" min="0" max="100" value="100" id="waterLevel" name="water-level" /></p>
<svg viewBox="0 0 300 300">
    <clipPath id="clip">
          <rect x="115" y="55" width="69" height="235" rx="20" ry="20" fill="red" />
    </clipPath>
    <image width="300" href="https://i.ibb.co/Mhfwtxp/image-removebg-preview-1.png" />
    <line id="tubeLiquid" clip-path="url(#clip)" pathLength="100" stroke-dasharray="100 100" x1="149.5" y1="290" x2="149.5" y2="50" stroke="#74ccf4" stroke-width="80" />
  </svg>

首先绘制剪辑路径和填充比例/进度条形状 - 不剪辑任何内容 - 以找到正确的坐标和尺寸。

然后您可以应用剪辑路径。
我为“tubeLiquid”元素使用了 元素,因为它允许我们将 pathLength 属性设置为 100。

我们可以通过更新 lines-dasharray 属性轻松更改当前填充值:

// show 100 %
stroke-dasharray="100 100"

// show 50 %
stroke-dasharray="50 100"

您会发现很多关于使用此方法实现各种动态仪表/进度条或动画饼图的示例,例如“在 JavaScript 中设置 svg 进度条百分比”

我发现的最接近的解决方案是我没有装满整个瓶子,但你只需要更改多边形中的一些坐标,我不了解形状和多边形。

<style>
.item {
  width: 150px;
  height: 150px;
}

#tubeLiquid {
  background-color: #74ccf4;
  clip-path: polygon(45% 19%, 41% 22%, 41% 29%, 41% 36%, 41% 43%, 41% 50%, 41% 57%, 41% 63%, 41% 70%, 41% 77%, 41% 83%, 41% 90%, 43% 93%, 50% 92%, 56% 93%, 60% 88%, 59% 81%, 60% 75%, 60% 68%, 60% 61%, 59% 55%, 59% 48%, 59% 42%, 59% 35%, 59% 29%, 58% 23%, 54% 19%);
}

#bottleMask{
  background-color: #FFFFFF;
  clip-path: polygon(45% 19%, 41% 22%, 41% 29%, 41% 36%, 41% 43%, 41% 50%, 41% 57%, 41% 63%, 41% 70%, 41% 77%, 41% 83%, 41% 90%, 43% 93%, 50% 92%, 56% 93%, 60% 88%, 59% 81%, 60% 75%, 60% 68%, 60% 61%, 59% 55%, 59% 48%, 59% 42%, 59% 35%, 59% 29%, 58% 23%, 54% 19%);
