Erode
Shrink bright pixels and expand darker pixels.
Erode
Method #
This node iteratively expands darker pixels in an image, eroding away at the bright areas and darkening the overall image. Useful for shrinking a mask which doesn’t fit tightly around the subject.
Parameters
These properties control the core behaviours of the node.
Parameter Details Blend Amount Changes the opacity of the new effect over the original image.
Iterations (Effect Size) How many times the erode function is run.
Mode Which directions the image is eroded in.
- Horizontal + Vertical : Both horizontal and vertical are eroded.
- Horizontal : Only horizontal is eroded.
- Vertical : Only vertical is eroded.
- Cross : Both diagonals are eroded.
Inputs
These properties control the core behaviours of the node.
| Parameter | Details |

| Blend Amount | Changes the opacity of the new effect over the original image. |
| Iterations (Effect Size) | How many times the erode function is run. |
| Mode | Which directions the image is eroded in.

| Name | Description | Typical Input |
|---|---|---|
| Active | Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance. | Envelope Modifier |
