  • width and height: The dimensions of the output image in pixels (default is 1024x1024).
  • outputCount: The number of images to generate in a single request, with a maximum of 4.
  • Additional parameters like guidanceScale, promptStrength, and refinementStyle can be adjusted to fine-tune the results.

Expected Output

The output of this action will be a set of generated images, each represented as a URI, showcasing the transformed line illustrations based on your input specifications.
