Edit

Outpaint

The Outpaint service inserts additional content in an image to fill in the space in any direction. Compared to other automated or manual attempts to expand the content in an image, the Outpaint service should minimize artifacts and signs that the original image has been edited.

How to use

Please invoke this endpoint with a POST request.

The headers of the request must include an API key in the authorization field. The body of the request must be multipart/form-data, and the accept header should be set to one of the following:

image/* to receive the image in the format specified by the output_format parameter.
application/json to receive the image encoded as base64 in a JSON response.

The body of the request must include:

image

Along with at least one outpaint direction:

left
right
up
down

Note: for best quality use outpaint direction values smaller or equal to your source image dimensions.

Each of these parameters should be set to a number between 0 and 2000, representing the number of pixels to outpaint in that direction.

Optionally, the body of the request may also include:

prompt
seed
output_format
creativity
style_preset

Note: for more details about these parameters please see the request schema below.

Authorizations

authorization

string

header

required

Use your Stability API key to authentication requests to this App.

Headers

authorization

string

required

Your Stability API key, used to authenticate your requests. Although you may have multiple keys in your account, you should use the same key for all requests to this API.

Minimum string length: 1

content-type

string

required

The content type of the request body. Do not manually specify this header; your HTTP client library will automatically include the appropriate boundary parameter.

Minimum string length: 1

Example:

"multipart/form-data"

enum<string>

default:image/*

Specify image/* to receive the bytes of the image directly. Otherwise specify application/json to receive the image as base64 encoded JSON.

Available options:

image/*,

application/json

stability-client-id

string

The name of your application, used to help us communicate app-specific debugging or moderation issues to you.

Maximum string length: 256

Example:

"my-awesome-app"

stability-client-user-id

string

A unique identifier for your end user. Used to help us communicate user-specific debugging or moderation issues to you. Feel free to obfuscate this value to protect user privacy.

Maximum string length: 256

Example:

"DiscordUser#9999"

stability-client-version

string

The version of your application, used to help us communicate version-specific debugging or moderation issues to you.

Maximum string length: 256

Example:

"1.2.1"

Body

multipart/form-data

image

file

required

The image you wish to outpaint.

Supported Formats:

jpeg
png
webp

Validation Rules:

Every side must be at least 64 pixels
Total pixel count must be between 4,096 and 9,437,184 pixels
The aspect ratio must be between 1:2.5 and 2.5:1

left

integer

default:0

The number of pixels to outpaint on the left side of the image. At least one outpainting direction must be supplied with a non-zero value.

Required range: 0 <= x <= 2000

right

integer

default:0

The number of pixels to outpaint on the right side of the image. At least one outpainting direction must be supplied with a non-zero value.

Required range: 0 <= x <= 2000

integer

default:0

The number of pixels to outpaint on the top of the image. At least one outpainting direction must be supplied with a non-zero value.

Required range: 0 <= x <= 2000

down

integer

default:0

The number of pixels to outpaint on the bottom of the image. At least one outpainting direction must be supplied with a non-zero value.

Required range: 0 <= x <= 2000

creativity

number

default:0.5

Controls the likelihood of creating additional details not heavily conditioned by the init image.

Required range: 0.2 <= x <= 0.5

prompt

string

What you wish to see in the output image. A strong, descriptive prompt that clearly defines elements, colors, and subjects will lead to better results.

To control the weight of a given word use the format (word:weight), where word is the word you'd like to control the weight of and weight is a value between 0 and 1. For example: The sky was a crisp (blue:0.3) and (green:0.8) would convey a sky that was blue and green, but more green than blue.

Maximum string length: 10000

seed

number

default:0

A specific value that is used to guide the 'randomness' of the generation. (Omit this parameter or pass 0 to use a random seed.)

Required range: 0 <= x <= 4294967294

output_format

enum<string>

default:png

Dictates the content-type of the generated image.

Available options:

png,

jpeg,

webp

style_preset

enum<string>

Guides the image model towards a particular style.

Available options:

enhance,

anime,

photographic,

digital-art,

comic-book,
