AI Uncrop

AI Uncrop reconstructs the missing parts of the main subject using only the visible portion.

If the edges of the main subject are clipped, they are seamlessly extended to restore the full form.

To uncrop an image, set the argument uncrop.mode to the value ai.auto and removeBackground to true:

(original image)	(uncropped image)

AI Uncrop works automatically:

• there’s no need to specify new dimensions or which edges to uncrop

• when no edges are cropped, the main subject will not be modified (i.e. AI Uncrop will be a no-op)

AI Uncrop is different from AI Expand: AI Uncrop focuses specifically on the main subject of the image.

If you want to give it a try, here's the code to reproduce the example above:

curl --request POST \
  --url https://image-api.photoroom.com/v2/edit \
  --header 'Content-Type: multipart/form-data' \
  --header 'x-api-key: YOUR_API_KEY_HERE' \
  --form imageFile=@/path/to/image.png \
  --form uncrop.mode=ai.auto \
  --form removeBackground=true

removeBackground may not be set to false: AI Uncrop always has to be combined with background removal.

The API will later start enforcing this.

Additional Parameters

uncrop.seed

If you make several calls to the Image Editing API with the same image, you will notice that it will generate a different uncropped subject every time.

In order to reduce the randomness, you can set a fixed value for the seed that the API's random generator will use. The value of the argument uncrop.seed can be any positive integer.

If you provide a value for uncrop.seed, then the API should produce similar-looking subject uncroppings for the same image.
