The bias attribute shifts the range of the filter. After applying the kernelMatrix of the <feConvolveMatrix> element to the input image to yield a number and applied the divisor attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.

Usage notes

Value <number>
Default value 0
Animatable Yes

One application of bias is when it is desirable to have 0.5 gray value be the zero response of the filter.
