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
pixels	IMAGE	required	-	-
upscale_factor	FLOAT	required	min: 1, max: 10000, step: 0.1	1.5
steps	INT	required	min: 1, max: 10000, step: 1	3
temp_prefix	STRING	required	-	""

Outputs

Index	Name	Type	Is List	Connection Reference
0	image	IMAGE	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 IterativeImageUpscale 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]
