kernelMatrix - SVG: Scalable Vector Graphics 编辑

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

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 attribute.

Only one element is using this attribute: <feConvolveMatrix>

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>

Usage notes

<list of numbers>

The list of <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.
