Kling Image Generation Node generates images from text prompts with the option to use a reference image for guidance. It creates one or more images based on your text description and reference settings, then returns the generated images as output.

Inputs

Parameter	Data Type	Required	Range	Description
`prompt`	STRING	Yes	-	Positive text prompt
`negative_prompt`	STRING	Yes	-	Negative text prompt
`image_type`	COMBO	Yes	Options from KlingImageGenImageReferenceType (extracted from source code)	Image reference type selection
`image_fidelity`	FLOAT	Yes	0.0 - 1.0	Reference intensity for user-uploaded images (default: 0.5)
`human_fidelity`	FLOAT	Yes	0.0 - 1.0	Subject reference similarity (default: 0.45)
`model_name`	COMBO	Yes	”kling-v1” (and other options from KlingImageGenModelName)	Model selection for image generation (default: “kling-v1”)
`aspect_ratio`	COMBO	Yes	”16:9” (and other options from KlingImageGenAspectRatio)	Aspect ratio for generated images (default: “16:9”)
`n`	INT	Yes	1 - 9	Number of generated images (default: 1)
`image`	IMAGE	No	-	Optional reference image
