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> <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>

<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 the number of entries in the value list, the filter primitive acts as a pass through filter.
