Prerequisites

To get started, you will need a valid Cognitive Actions API key and a basic understanding of making API calls.

Generate Image with Inpainting

The "Generate Image with Inpainting" action allows developers to create images by filling in gaps or altering existing visuals based on a text prompt. This action is particularly useful for tasks that require customization or enhancement of images, enabling a high degree of control over the final output.

Input Requirements

The input for this action consists of various parameters, including:

  • Mask: A URI pointing to the input mask for inpainting mode, where black areas remain unchanged and white areas are inpainted.
  • Seed: An optional integer seed for random image generation.
  • Image: A URI of the input image that serves as the base for inpainting.
  • Width and Height: Dimensions of the output image, defaulting to 1024 pixels.
  • Prompt: A text string guiding the image generation process.
  • LoRA Scale: A scale factor for adjusting the model, ranging from 0 to 1.
  • Refine Style: Determines the refinement approach, with options like "no_refiner" or "expert_ensemble_refiner".
  • Guidance Scale: A number indicating the intensity of guidance in image generation.
  • Output Image Count: Specifies how many images to generate (up to 4).

Expected Output

The expected output is an array of generated image URLs, which can be directly accessed and utilized in your projects. For example:

[
  "https://assets.cognitiveactions.com/invocations/72c3dacc-d4cd-4241-a0d2-925514b337d1/6956e221-b3d9-457d-8987-d4282792800e.png",
