Split Image Channels

KJNodes/image

SplitImageChannels

Splits image channels into images where the selected channel is repeated for all channels, and the alpha as a mask.

Example

JSON Example

{
  "class_type": "SplitImageChannels",
  "inputs": {
    "image": [
      "node_id",
      0
    ]
  }
}

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	-	-

Outputs

Index	Name	Type	Is List	Connection Reference
0	red	IMAGE	No	["{node_id}", 0]
1	green	IMAGE	No	["{node_id}", 1]
2	blue	IMAGE	No	["{node_id}", 2]
3	mask	MASK	No	["{node_id}", 3]

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 SplitImageChannels 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 (IMAGE): ["5", 0]
• green (IMAGE): ["5", 1]
• blue (IMAGE): ["5", 2]
