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<br />(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"<br />(and other options from KlingImageGenModelName)                | Model selection for image generation (default: "kling-v1")  |
| `aspect_ratio`    | COMBO     | Yes      | "16:9"<br />(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                                    |

**Parameter Constraints:**

* The `image` parameter is optional, but when provided, the kling-v1 model does not support reference images
* Prompt and negative prompt have maximum length limitations (MAX\_PROMPT\_LENGTH\_IMAGE\_GEN)
* When no reference image is provided, the `image_type` parameter is automatically set to None

## Outputs

| Output Name | Data Type | Description                                      |
| ----------- | --------- | ------------------------------------------------ |
| `output`    | IMAGE     | Generated image(s) based on the input parameters |
