Inputs
| Input | Type | Required | Default | Meaning |
|---|---|---|---|---|
| in | Image | Required | — | See the overview for the node's documented behavior. |
Properties
| Property | Type | Default | Animatable | Range / options | Effect |
|---|---|---|---|---|---|
| Mode | Enum | Sobel | Not declared | Sobel · Prewitt · Laplacian | Selects the mode behavior; each option changes the operation described in the overview. |
| Strength | Scalar | 1 | Yes | Hard 0..4 · UI range: soft | Animatable control; changing it over time varies the node response. |
| Output | Enum | Magnitude | Not declared | Magnitude · Direction · Binary | Selects the output behavior; each option changes the operation described in the overview. |
Outputs
| Output | Type | Meaning |
|---|---|---|
| out | Image | The production node output described by the overview. |
Usage
In practice
- Use Edge Detect when the graph needs Detects internal image gradients with Sobel, Prewitt, or Laplacian kernels.
- 3×3 edge processor with selectable kernel and output interpretation; source alpha is preserved.
- Place it after the image or mask it should process, and check its alpha and edge behavior before using the result in a tiled graph.
Notes / limitations
- No step is declared for Strength.
