# Outpaint Image

`POST /painting/outpaint`

## Request

- Base URL: `https://genai-api.picsart.io/v1`
- URL: `https://genai-api.picsart.io/v1/painting/outpaint`
- Auth: API key in header `X-Picsart-API-Key`

The **Outpainting** service enables outpainting (image2image), allowing users to extend or replace specific parts of an image. This is a reversed form of the Inpainting service (drawing outside of the mask, not inside).
It supports two operational modes:
  * Single Image Mode: Upload one RGBA image. The API enhances the outer area with content based on the prompt parameter.
  * Mask Mode: Provide an RGBA image along with a mask of the same size. The API applies this mask to paint beyond the masked region, using content determined by the prompt parameter.

## Request body `multipart/form-data`

- object
  - `image` string, binary: Source image file (binary). (If this parameter is present, the other image source parameters must be empty.)
  - `image_url` string, uri: Source image URL. (If this parameter is present, the other image source parameters must be empty.)
  - `image_id` string: Deprecated. Source image ID of an image previously uploaded to Picsart or result image ID from a different API. (If this parameter is present, the other image source parameters must be empty.)
  - `mask_image` string, binary: Source mask file (binary). (If this parameter is present, the other mask source parameters must be empty.)
  - `mask_image_url` string, uri: Source mask URL. (If this parameter is present, the other mask source parameters must be empty.)
  - `mask_image_id` string: Deprecated. Source mask ID of an mask previously uploaded to Picsart or result mask ID from a different API. (If this parameter is present, the other mask source parameters must be empty.)
  - `prompt` string, required: The prompt.
  - `count` integer: The number of images to generate.
  - `format` 'JPG' | 'PNG' | 'WEBP': Optionally select one of the image formats (JPG is default). Options are as follows: * JPG * PNG * WEBP
  - `mode` 'sync' | 'async': Deprecated. The mode parameter is now deprecated. To control synchronous vs asynchronous execution, use the standard HTTP Prefer header (RFC 7240). If both mode and Prefer are provided, Prefer takes precedence. For migration guidance and examples, see the [Sync and Async Execution guide](https://docs.picsart.io/docs/sync-async-execution). Use this query parameter to establish the processing mode. Acceptable values are sync, async and auto (sync is default): * sync: issues a synchronous request, response is given when the result is ready. * async: forces an asynchronous request, the response, which is instantaneous, contains a "transaction_id" which is used to poll for the result. * REMOVED - auto: the processing mode decision is made by the service, which depends upon the expected processing time.

## Response `200`

Success.
