Outpaints image based on prompt.

Example

JSON Example

{
  "class_type": "FluxProExpandNode",
  "inputs": {
    "image": [
      "node_id",
      0
    ],
    "prompt": "",
    "prompt_upsampling": false,
    "top": 0,
    "bottom": 0,
    "left": 0,
    "right": 0,
    "guidance": 60,
    "steps": 50,
    "seed": 0
  }
}

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

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 FluxProExpandNode 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]
