About Image Outpaint

Expands a source image from `image_url` by setting `expand_left`, `expand_right`, `expand_top` and `expand_bottom`, each 0 to 700 pixels. Only the added margins are filled in. `zoom_out_percentage` (0 to 90, default 20) shrinks the original within the frame first, and an optional `prompt` of up to 500 characters guides the new content. It returns 1 to 4 images in png, jpeg, jpg or webp.

Parameters

Send either the canonical name or the native name, not both. Canonical names
