The in2 attribute identifies the second input for the given filter primitive. It works exactly like the in attribute.
Three elements use this attribute: <feBlend>, <feComposite> and <feDisplacementMap>.
feBlend
For <feBlend>, in2 defines the second input image to the blending operation.
| Value | SourceGraphic | SourceAlpha | BackgroundImage | BackgroundAlpha | FillPaint | StrokePaint | <filter-primitive-reference> |
|---|---|
| Default value | SourceGraphic for first filter primitive, otherwise result of previous filter primitive |
| Animatable | Yes |
feComposite
For <feComposite>, in2 defines the second input image to the compositing operation.
| Value | SourceGraphic | SourceAlpha | BackgroundImage | BackgroundAlpha | FillPaint | StrokePaint | <filter-primitive-reference> |
|---|---|
| Default value | SourceGraphic for first filter primitive, otherwise result of previous filter primitive |
| Animatable | Yes |
feDisplacementMap
For <feDisplacementMap>, in2 defines the second input image, which is used to displace the pixels in the image defined in the in attribute.
| Value | SourceGraphic | SourceAlpha | BackgroundImage | BackgroundAlpha | FillPaint | StrokePaint | <filter-primitive-reference> |
|---|---|
| Default value | SourceGraphic for first filter primitive, otherwise result of previous filter primitive |
| Animatable | Yes |
