  title: Adobe Creative Cloud Firefly Generative Expand
  summary: Upload an image then expand it beyond its original boundaries with AI-generated content.
  description: >-
    Generative expand (outpainting) with Adobe Firefly. The workflow uploads a
    source image to Firefly temporary storage to obtain an upload ID, then
    calls the expand endpoint with the target dimensions and an optional prompt
    so the canvas grows and the new edges are filled with content that
    seamlessly extends the scene. Every step spells out its request inline,
    including the bearer token and x-api-key, so the flow can be read and run
    without opening the underlying OpenAPI description.
