{{SVGRef}}

La primitive de filtre [SVG](/fr/docs/Web/SVG) **`<feComposite>`** effectue la combinaison de deux images en entrée, pixel par pixel, en utilisant une des opérations de composition de Porter-Duff: `over`_,_ `in`_,_ `atop`_,_ `out`_,_ `xor`, et `lighter`. Il est également possible d'appliquer une opération de type `arithmetic` (avec un résultat borné entre \[0..1]).

L'opération `arithmetic` est utile pour combiner le résultat de {{SVGElement("feDiffuseLighting")}} et {{SVGElement("feSpecularLighting")}} avec des textures. Si l'opération `arithmetic` est choisie, chaque pixel est calculé à l'aide de la formule suivante:

```plain
result = k1*i1*i2 + k2*i1 + k3*i2 + k4
```

où

- `i1` et `i2` indiquent les valeurs des pixels correspondant aux images en entrée, {{SVGAttr("in")}} et {{SVGAttr("in2")}} respectivement
- `k1, k2, k3` et `k4` indiquent les valeurs des attributs du même nom
