JSON Example

{
  "class_type": "PorterDuffImageComposite",
  "inputs": {
    "source": [
      "node_id",
      0
    ],
    "source_alpha": [
      "node_id",
      0
    ],
    "destination": [
      "node_id",
      0
    ],
    "destination_alpha": [
      "node_id",
      0
    ],
    "mode": "DST"
  }
}

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
source	IMAGE	required	-	-
source_alpha	MASK	required	-	-
destination	IMAGE	required	-	-
destination_alpha	MASK	required	-	-
mode	COMBO	required	-	"DST"

Outputs

Index	Name	Type	Is List	Connection Reference
0	IMAGE	IMAGE	No	["{node_id}", 0]
1	MASK	MASK	No	["{node_id}", 1]

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

Example

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

• IMAGE (IMAGE): ["5", 0]
• MASK (MASK): ["5", 1]
