This filter primitive performs the combination of two input images pixel-wise in image space using one of the Porter-Duff compositing operations: over
, in
, atop
, out
, xor
and lighter
. Additionally, a component-wise arithmetic
operation (with the result clamped between [0..1]) can be applied.
The arithmetic
operation is useful for combining the output from the <feDiffuseLighting>
and <feSpecularLighting>
filters with texture data. If the arithmetic
operation is chosen, each result pixel is computed using the following formula:
result = k1*i1*i2 + k2*i1 + k3*i2 + k4
where:
i1
andi2
indicate the corresponding pixel channel values of the input image, which map toin
andin2
respectivelyk1, k2, k3
andk4
indicate the values of the attributes with the same name
