Preview Bridge (Image)

ImpactPack/UtilOutput Node

PreviewBridge

This is a feature that allows you to edit and send a Mask over a image. If the block is set to 'is_empty_mask', the execution is stopped when the mask is empty.

Example

JSON Example

{
  "class_type": "PreviewBridge",
  "inputs": {
    "images": [
      "node_id",
      0
    ],
    "image": "https://example.com/input-image.png"
  }
}

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	-	-
image	STRINGURL: Image	required	-	""
block?	BOOLEAN	optional	-	false
restore_mask?	ENUM 3 options never always if_same_size	optional	-	-

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 PreviewBridge 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]
