MaskFromRGBCMYBW+

Example

JSON Example

{
  "class_type": "MaskFromRGBCMYBW+",
  "inputs": {
    "image": [
      "node_id",
      0
    ],
    "threshold_r": 0.15,
    "threshold_g": 0.15,
    "threshold_b": 0.15
  }
}

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
image	IMAGE	required	-	-
threshold_r	FLOAT	required	min: 0, max: 1, step: 0.01	0.15
threshold_g	FLOAT	required	min: 0, max: 1, step: 0.01	0.15
threshold_b	FLOAT	required	min: 0, max: 1, step: 0.01	0.15

Outputs

Index	Name	Type	Is List	Connection Reference
0	red	MASK	No	["{node_id}", 0]
1	green	MASK	No	["{node_id}", 1]
2	blue	MASK	No	["{node_id}", 2]
3	cyan	MASK	No	["{node_id}", 3]
4	magenta	MASK	No	["{node_id}", 4]
5	yellow	MASK	No	["{node_id}", 5]
6	black	MASK	No	["{node_id}", 6]
7	white	MASK	No	["{node_id}", 7]

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 MaskFromRGBCMYBW+ node in your workflow, and output_index is the index from the table above.

Example

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

• red (MASK): ["5", 0]
• green (MASK): ["5", 1]
• blue (MASK): ["5", 2]
