Separate Masks

KJNodes/maskingOutput Node

SeparateMasks

Separates a mask into multiple masks based on the size of the connected components.

Example

JSON Example

{
  "class_type": "SeparateMasks",
  "inputs": {
    "mask": [
      "node_id",
      0
    ],
    "size_threshold_width": 256,
    "size_threshold_height": 256,
    "mode": "convex_polygons",
    "max_poly_points": 8
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
mask	MASK	required	-	-
size_threshold_width	INT	required	min: 0, max: 4096, step: 1	256
size_threshold_height	INT	required	min: 0, max: 4096, step: 1	256
mode	ENUM 3 options convex_polygons area box	required	-	-
max_poly_points	INT	required	min: 3, max: 32, step: 1	8

Outputs

Index	Name	Type	Is List	Connection Reference
0	mask	MASK	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this SeparateMasks node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• mask (MASK): ["5", 0]
