Color To Mask

KJNodes/masking

ColorToMask

Converts chosen RGB value to a mask. With batch inputs, the **per_batch** controls the number of images processed at once.

Example

JSON Example

{
  "class_type": "ColorToMask",
  "inputs": {
    "images": [
      "node_id",
      0
    ],
    "invert": false,
    "red": 0,
    "green": 0,
    "blue": 0,
    "threshold": 10,
    "per_batch": 16
  }
}

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
images	IMAGE	required	-	-
invert	BOOLEAN	required	-	false
red	INT	required	min: 0, max: 255, step: 1	0
green	INT	required	min: 0, max: 255, step: 1	0
blue	INT	required	min: 0, max: 255, step: 1	0
threshold	INT	required	min: 0, max: 255, step: 1	10
per_batch	INT	required	min: 1, max: 4096, step: 1	16

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 ColorToMask 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]
