kernelMatrix attribute defines the list of numbers that make up the kernel matrix for the <feConvolveMatrix> 元素。

Values are separated by space characters and/or a comma. The number of entries in the list must equal to <orderX> by <orderY> as defined in the order 属性。

You can use this attribute with the following SVG elements:

• <feConvolveMatrix>

范例

html, body, svg {
  height: 100%;
}

								

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <filter id="convolveMatrix1" x="0" y="0" width="100%" height="100%">
    <feConvolveMatrix kernelMatrix="1 1 0 0 0 0 0 0 -1"/>
  </filter>
  <filter id="convolveMatrix2" x="0" y="0" width="100%" height="100%">
    <feConvolveMatrix kernelMatrix="-1 0 0 0 0 0 0 0 1"/>
  </filter>
  <image xlink:href="//developer.mozilla.org/files/6457/mdn_logo_only_color.png" width="200" height="200"
      style="filter:url(#convolveMatrix1);"/>
  <image xlink:href="//developer.mozilla.org/files/6457/mdn_logo_only_color.png" width="200" height="200"
      style="filter:url(#convolveMatrix2); transform:translateX(220px);"/>
</svg>

								

用法注意事项

<list of numbers>

列表 <number> s that make up the kernel matrix for the convolution. Values are separated by space characters and/or a comma. The number of entries in the list must equal <orderX> times <orderY> .

If the result of orderX * orderY is not equal to the number of entries in the value list, the filter primitive acts as a pass through filter.
