Outpaints image based on prompt. This node expands an image by adding pixels to the top, bottom, left, and right sides while generating new content that matches the provided text description.

Inputs

Parameter	Data Type	Required	Range	Description
`image`	IMAGE	Yes	-	The input image to be expanded
`prompt`	STRING	No	-	Prompt for the image generation (default: "")
`prompt_upsampling`	BOOLEAN	No	-	Whether to perform upsampling on the prompt. If active, automatically modifies the prompt for more creative generation, but results are nondeterministic (same seed will not produce exactly the same result). (default: False)
`top`	INT	No	0-2048	Number of pixels to expand at the top of the image (default: 0)
`bottom`	INT	No	0-2048	Number of pixels to expand at the bottom of the image (default: 0)
`left`	INT	No	0-2048	Number of pixels to expand at the left of the image (default: 0)
`right`	INT	No	0-2048	Number of pixels to expand at the right of the image (default: 0)
`guidance`	FLOAT	No	1.5-100	Guidance strength for the image generation process (default: 60)
`steps`	INT	No	15-50	Number of steps for the image generation process (default: 50)
`seed`	INT	No	0-18446744073709551615	The random seed used for creating the noise. (default: 0)
