Generate Custom Inpainted Images

The "Generate Custom Inpainted Images" action allows developers to create inpainted images by specifying various parameters to control the output. This action is particularly useful for modifying existing images or generating new ones based on textual prompts.

Purpose

This action solves the challenge of creating high-quality, customized images through a simple input mechanism, enabling developers to focus on their creative vision rather than the technical details of image processing.

Input Requirements

To utilize this action, you need to provide several inputs:

  • Prompt: A textual description guiding the image generation.
  • Mask: A URI pointing to an image mask for inpainting.
  • Image: URI of the input image for modification.
  • Dimensions: Width and height settings, if custom aspect ratios are used.
  • Additional Parameters: Options like guidance scale, output quality, and the number of outputs.

For example, a typical input might look like this:

{
  "prompt": "linnea character turn around with three different poses, kawaii, cute, blue hair, young girl",
  "extraLora": "aramintak/linnea-flux-beta/versions/7d86be5fa7e383f1b1e867ebd01d650159b8881cc0e0eb4e67b82161eba9fd08",
  "loraScale": 0.4,
  "numOutputs": 4,
  "outputFormat": "webp",
  "guidanceScale": 3.5,
  "outputQuality": 90,
  "extraLoraScale": 0.9,
  "inferenceModel": "dev",
  "promptStrength": 0.8,
  "imageAspectRatio": "16:9",
  "numInferenceSteps": 28
}

Expected Output

The output will be a series of image URLs, each representing a generated inpainted image based on the provided parameters. For instance:

  • https://assets.cognitiveactions.com/invocations/945b2879-7018-4e86-988a-ed242fa3f5be/7b66b012-547a-490d-b18b-9e56a5d5b463.webp
  • https://assets.cognitiveactions.com/invocations/945b2879-7018-4e86-988a-ed242fa3f5be/f013ad3f-eef3-49ed-a8ec-953351010ec9.webp

Use Cases for this Action

  • Artistic Projects: Ideal for artists looking to bring their concepts to life with minimal effort.
  • Game Development: Quickly generate diverse character assets or backgrounds based on specific design prompts.
  • Advertising: Create tailored visuals for campaigns that resonate with target audiences by adjusting prompts and styles dynamically.
