imagekit = ImageKit(
    private_key='your_private_key',
    public_key='your_public_key',
    url_endpoint='your_url_endpoint'
)

Change log

This document presents a list of changes that break the existing functionality of previous versions. We try to minimize these disruptions, but they are sometimes unavoidable, especially in significant updates. Therefore, versions are marked semantically and tagged as major upgrades whenever such breaking changes occur.

Breaking History:

Changes from 3.2.0 -> 4.0.0 are listed below

1. Overlay syntax update

• In version 4.0.0, we've removed the old overlay syntax parameters for transformations, such as oi, ot, obg, and more. These parameters are deprecated and will start returning errors when used in URLs. Please migrate to the new layers syntax that supports overlay nesting, provides better positional control, and allows more transformations at the layer level. You can start with examples to learn quickly.
• You can migrate to the new layers syntax using the raw transformation parameter.

Changes from 2.2.8 -> 3.0.0 are listed below

1. Throw an Error:

What changed

• Before the upgrade, an error dict was coming in the return object of any function call. Now, SDK throws an exception in case of an error.

Who is affected?

• This affects any development in your software that calls APIs from ImageKit IO and handles errors based on what's returned.

How should I update my code?

• To avoid failures in an application, you could handle errors as documented here

Usage

You can use this Python SDK for three different kinds of methods:

• URL Generation
• File Upload
• File Management
• Utility Functions

URL Generation

1. Using Image path and endpoint (hostname)

This method allows you to create a URL using the relative file path where the image exists and the URL endpoint(url_endpoint) you want to use to access the image. You can refer to the documentation here to read more about URL endpoints in ImageKit and the section about image origins to understand about paths with different kinds of origins.

The file can be an image, video, or any other static file supported by ImageKit.

imagekit_url = imagekit.url({
    "path": "/default-image.jpg",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [{
        "height": "300",
        "width": "400",
        "raw": "ar-4-3,q-40"
    }],
})

Sample Result URL -

https://ik.imagekit.io/your_imagekit_id/endpoint/tr:h-300,w-400,ar-4-3,q-40/default-image.jpg

2. Using full image URL

This method allows you to add transformation parameters to an absolute URL using the src parameter. This method should be used if you have the complete image URL stored in your database.

image_url = imagekit.url({
    "src": "https://ik.imagekit.io/your_imagekit_id/endpoint/default-image.jpg",
    "transformation": [{
        "height": "300",
        "width": "400",
        "raw": "ar-4-3,q-40"
    }]
})

Sample Result URL -

https://ik.imagekit.io/your_imagekit_id/endpoint/default-image.jpg?tr=h-300%2Cw-400%2Car-4-3%2Cq-40

The .url() method accepts the following parameters.

Option	Description
url_endpoint	Optional. The prepended base URL before the path of the image. If not specified, the URL Endpoint specified during SDK initialization gets used. For example, https://ik.imagekit.io/your_imagekit_id/endpoint/
path	Conditional. A path at which the image exists. For example, /path/to/image.jpg. Specify a path or src parameter for URL generation.
src	Conditional. Complete URL of an image already mapped to ImageKit. For example, https://ik.imagekit.io/your_imagekit_id/endpoint/path/to/image.jpg. Specify a path or src parameter for URL generation.
transformation	Optional. Specify an array of objects with name and the value in key-value pair to apply transformation params in the URL. Append different steps of a chained transformation as different objects of the array. This document includes a complete list of supported transformations in the SDK with some examples. If one uses an unspecified transformation name, it gets applied as it is in the URL.
transformation_position	Optional. The default value is path, which places the transformation string as a path parameter in the URL. One can also specify it as a query, which adds the transformation string as the query parameter tr in the URL. Suppose one uses the src parameter to create the URL. In that case, the transformation string is always a query parameter.
query_parameters	Optional. These are the other query parameters that one wants to add to the final URL. These can be any query parameters and are not necessarily related to ImageKit. Especially useful if one wants to add some versioning parameter to their URLs.
signed	Optional. Boolean. The default is false. If set to true, the SDK generates a signed image URL adding the image signature to the image URL. One can only use this if they create the URL with the url_endpoint and path parameters, not the src parameter.
expire_seconds	Optional. Integer. Used along with the signed parameter to specify the time in seconds from now when the URL should expire. If specified, the URL contains the expiry timestamp, and the image signature is modified accordingly.

Examples of generating URLs

1. Chained Transformations as a query parameter

image_url = imagekit.url({
    "path": "/default-image.jpg",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [
        {
            "height": "300",
            "width": "400"
        },
        {
            "rotation": 90
        }
    ],
    "transformation_position": "query"
})

Sample Result URL -

https://ik.imagekit.io/your_imagekit_id/endpoint/default-image.jpg?tr=h-300%2Cw-400%3Art-90

2. Sharpening, contrast transform and progressive JPG image

Add transformations like Sharpening to the URL with or without any other value. To use such transforms without specifying a value, set it as "-" in the transformation object. Otherwise, use the value that one wants to add to this transformation.

image_url = imagekit.url({
    "src": "https://ik.imagekit.io/your_imagekit_id/endpoint/default-image.jpg",
    "transformation": [{
        "format": "jpg",
        "progressive": "true",
        "effect_sharpen": "-",
        "effect_contrast": "1"
    }]
})

Sample Result URL -

# Note that because the `src` parameter is in effect, the transformation string gets added as a query parameter `tr`

https://ik.imagekit.io/your_imagekit_id/endpoint/default-image.jpg?tr=f-jpg%2Cpr-true%2Ce-sharpen%2Ce-contrast-1

3. Signed URL that expires in 300 seconds with the default URL endpoint and other query parameters

image_url = imagekit.url({
    "path": "/default-image.jpg",
    "query_parameters": {
        "p1": "123",
        "p2": "345"
    },
    "transformation": [{
        "height": "300",
        "width": "400"
    }],
    "signed": True,
    "expire_seconds": 300
})

Sample Result URL -

https://ik.imagekit.io/your_imagekit_id/tr:h-300,w-400/default-image.jpg?p1=123&p2=345&ik-t=1658899345&ik-s=8f03aca28432d4e87f697a48143efb4497bbed9e

4. Adding overlays

ImageKit.io enables you to apply overlays to images and videos using the raw parameter with the concept of layers. The raw parameter facilitates incorporating transformations directly in the URL. A layer is a distinct type of transformation that allows you to define an asset to serve as an overlay, along with its positioning and additional transformations.

Text as overlays

You can add any text string over a base video or image using a text layer (l-text).

For example:

image_url = imagekit.url({
    "path": "/default-image",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [{
        "height": "300",
        "width": "400",
        "raw": "l-text,i-Imagekit,fs-50,l-end"
    }],
})

Sample Result URL

https://ik.imagekit.io/your_imagekit_id/tr:h-300,w-400,l-text,i-Imagekit,fs-50,l-end/default-image.jpg

Image as overlays

You can add an image over a base video or image using an image layer (l-image).

For example:

image_url = imagekit.url({
    "path": "/default-image",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [{
        "height": "300",
        "width": "400",
        "raw": "l-image,i-default-image.jpg,w-100,b-10_CDDC39,l-end"
    }],
})

Sample Result URL

https://ik.imagekit.io/your_imagekit_id/tr:h-300,w-400,l-image,i-default-image.jpg,w-100,b-10_CDDC39,l-end/default-image.jpg

Solid color blocks as overlays

You can add solid color blocks over a base video or image using an image layer (l-image).

For example:

image_url = imagekit.url({
    "path": "/img/sample-video",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [{
        "height": "300",
        "width": "400",
        "raw": "l-image,i-ik_canvas,bg-FF0000,w-300,h-100,l-end"
    }],
})

Sample Result URL

https://ik.imagekit.io/your_imagekit_id/tr:h-300,w-400,l-image,i-ik_canvas,bg-FF0000,w-300,h-100,l-end/img/sample-video.mp4

5. Arithmetic expressions in transformations

ImageKit allows use of arithmetic expressions in certain dimension and position-related parameters, making media transformations more flexible and dynamic.

For example:

image_url = imagekit.url({
    "path": "/default-image.jpg",
    "url_endpoint": "https://ik.imagekit.io/your_imagekit_id/endpoint/",
    "transformation": [{
        "height": "ih_div_2",
        "width": "iw_div_4",
        "border": "cw_mul_0.05_yellow"
    }],
})

Sample Result URL

https://ik.imagekit.io/your_imagekit_id/default-image.jpg?tr=w-iw_div_4,h-ih_div_2,b-cw_mul_0.05_yellow

List of transformations

The complete list of transformations supported and their usage in ImageKit is available here. The SDK gives a name to each transformation parameter, making the code simpler, more straightforward, and readable. If a transformation is supported in ImageKit, though it cannot be found in the table below, then use the transformation code from ImageKit docs as the name when using the URL function.

If you want to generate transformations in your application and add them to the URL as it is, use the raw parameter.

Supported Transformation Name	Translates to parameter
height	h
width	w
aspect_ratio	ar
quality	q
crop	c
crop_mode	cm
x	x
y	y
focus	fo
format	f
radius	r
background	bg
border	b
rotation	rt
blur	bl
named	n
progressive	pr
lossless	lo
trim	t
metadata	md
color_profile	cp
default_image	di
dpr	dpr
effect_sharpen	e-sharpen
effect_usm	e-usm
effect_contrast	e-contrast
effect_gray	e-grayscale
effect_shadow	e-shadow
effect_gradient	e-gradient
original	orig
raw	replaced by the parameter value

File Upload

The SDK provides a simple interface using the .upload_file() method to upload files to the ImageKit Media library. It accepts all the parameters supported by the ImageKit Upload API.

The upload_file() method requires at least the file as (URL/Base64/Binary) and the file_name parameter to upload a file. The method returns a dict data in case of success, or it will throw a custom exception in case of failure. Use the options parameter to pass other parameters supported by the ImageKit Upload API. Use the same parameter name as specified in the upload API documentation.

Simple usage

from imagekitio.models.UploadFileRequestOptions import UploadFileRequestOptions

extensions = [
    {
        'name': 'remove-bg',
        'options': {
            'add_shadow': True,
            'bg_color': 'pink'
        }
    },
    {
        'name': 'google-auto-tagging',
        'minConfidence': 80,
        'maxTags': 10
    }
]

transformation = {
    'pre': 'l-text,i-Imagekit,fs-50,l-end', 
    'post': [
        {
            'type': 'transformation', 
            'value': 'w-100'
        }
    ]
}

options = UploadFileRequestOptions(
    use_unique_file_name=False,
    tags=['abc', 'def'],
    folder='/testing-python-folder/',
    is_private_file=False,
    custom_coordinates='10,10,20,20',
    response_fields=['tags', 'custom_coordinates', 'is_private_file',
                     'embedded_metadata', 'custom_metadata'],
    extensions=extensions,
    webhook_url='https://webhook.site/c78d617f-33bc-40d9-9e61-608999721e2e',
    overwrite_file=True,
    overwrite_ai_tags=False,
    overwrite_tags=False,
    overwrite_custom_metadata=True,
    custom_metadata={'testss': 12},
    transformation=transformation,
    checks="'request.folder' : '/testing-python-folder'", # To run server side checks before uploading files. Notice the quotes around request.folder and /testing-python-folder.
    is_published=True
)

result = imagekit.upload_file(file='<url|base_64|binary>', # required
                              file_name='my_file_name.jpg', # required
                              options=options)

# Final Result
print(result)

# Raw Response
print(result.response_metadata.raw)

# print that uploaded file's ID
print(result.file_id)

If the upload succeeds, the result will be the UploadFileResult class.

If the upload fails, the custom exception will be thrown with:

• response_help for any kind of help
• response_metadata with raw, http_status_code and headers
• message can be called to get the error message received from ImageKit's servers.

File Management

The SDK provides a simple interface for all the media APIs mentioned here to manage your files. This also returns result.

1. List & Search Files

Accepts an object specifying the parameters used to list and search files. All parameters specified in the documentation here can be passed with the correct values to get the results.

Applying Filters

    file_type='all',
    limit=5,
    skip=0,
    tags='Software, Developer, Engineer',
)

result = imagekit.list_files(options=options)

# Final Result
print(result)

# Raw Response
print(result.response_metadata.raw)

# print the first file's ID
print(result.list[0].file_id)

Advance Search

In addition, you can fine-tune your query by specifying various filters by generating a query string in a Lucene-like syntax and providing this generated string as the value of the search_query.

from imagekitio.models.ListAndSearchFileRequestOptions import ListAndSearchFileRequestOptions

options = ListAndSearchFileRequestOptions(
    search_query="createdAt >= '2d' OR size < '2mb' OR format='png'",
)

result = imagekit.list_files(options=options)

Utility functions

We have included the following commonly used utility functions in this package.

Authentication parameter generation

Suppose one wants to implement client-side file upload. In that case, one will need a token, expiry timestamp, and a valid signature for that upload. The SDK provides a simple method that one can use in their code to generate these authentication parameters.

Note: Any client-side code should never expose The Private API Key. One must always generate these authentications parameters on the server-side

authentication

authentication_parameters = imagekit.get_authentication_parameters(token, expire)

Returns

{
    "token": "unique_token",
    "expire": "valid_expiry_timestamp",
    "signature": "generated_signature"
}

Both the token and expire parameters are optional. If not specified, the SDK uses the UUID to generate a random token and internally generates a valid expiry timestamp. The token and expire used to generate signature is part of a response returned by the server.

Distance calculation between two pHash values

Perceptual hashing allows you to construct a has value that uniquely identifies an input image based on the contents of an image. imagekit.io metadata API returns the pHash value of an image in the response. You can use this value to find a duplicate or similar image by calculating the distance between the two images.

This SDK exposes the phash_distance function to calculate the distance between two pHash values. It accepts two pHash hexadecimal strings and returns a numeric value indicative of the difference between the two images.

def calculate_distance():
    # fetch metadata of two uploaded image files
    ...
    # extract pHash strings from both: say 'first_hash' and 'second_hash'
    ...
    # calculate the distance between them:

    distance = imagekit.phash_distance(first_hash, second_hash)
    return distance

Distance calculation examples

imagekit.phash_distance('f06830ca9f1e3e90', 'f06830ca9f1e3e90')
# output: 0 (same image)

imagekit.phash_distance('2d5ad3936d2e015b', '2d6ed293db36a4fb')
# output: 17 (similar images)

imagekit.phash_distance('a4a65595ac94518b', '7838873e791f8400')
# output: 37 (dissimilar images)

HTTP response metadata of Internal API

HTTP response metadata of the internal API call can be accessed using the _response_metadata on the Result object. Example:

result = imagekit.upload_file(
    file="<url|base_64|binary>",
    file_name="my_file_name.jpg",
)

# Final Result
print(result)
print(result.response_metadata.raw)
print(result.response_metadata.http_status_code)
print(result.response_metadata.headers)

Handling errors

Catch and respond to invalid data, internal problems, and more.

ImageKit Python SDK raises exceptions for many reasons, such as not found, invalid parameters, authentication, and internal server errors. Therefore, we recommend writing code that gracefully handles all possible API exceptions.

Example:

from imagekitio.exceptions.BadRequestException import BadRequestException
from imagekitio.exceptions.UnauthorizedException import UnauthorizedException
from imagekitio.exceptions.ForbiddenException import ForbiddenException
from imagekitio.exceptions.TooManyRequestsException import TooManyRequestsException
from imagekitio.exceptions.InternalServerException import InternalServerException
from imagekitio.exceptions.PartialSuccessException import PartialSuccessException
from imagekitio.exceptions.NotFoundException import NotFoundException
from imagekitio.exceptions.UnknownException import UnknownException

try:

    # Use ImageKit's SDK to make requests...
    print('Run image kit api')
except BadRequestException, e:
    # Missing or Invalid parameters were supplied to Imagekit.io's API
    print('Status is: ' + e.response_metadata.http_status_code)
    print('Message is: ' + e.message)
    print('Headers are: ' + e.response_metadata.headers)
    print('Raw body is: ' + e.response_metadata.raw)
except UnauthorizedException, e:
    print(e)
except ForbiddenException, e:
    # No valid API key was provided.
    print(e)
except TooManyRequestsException, e:
    # Can be for the following reasons:
    # ImageKit could not authenticate your account with the keys provided.
    # An expired key (public or private) was used with the request.
    # The account is disabled.
    # If you use the upload API, the total storage limit (or upload limit) is exceeded.
    print(e)
except InternalServerException, e:
    # Too many requests made to the API too quickly
    print(e)
except PartialSuccessException, e:
    # Something went wrong with ImageKit.io API.
    print(e)
except NotFoundException, e:
    # Error cases on partial success.
    print(e)
except UnknownException, e:
    # If any of the field or parameter is not found in the data
    print(e)

# Something else happened, which can be unrelated to ImageKit; the reason will be indicated in the message field

To integrate ImageKit Samples in the Python, the code samples covered here are hosted on GitHub - https://github.com/imagekit-samples/quickstart/tree/master/python.

Open the python/sample.py file and replace placeholder credentials with actual values. You can get the value of URL-endpoint from your ImageKit dashboard. API keys can be obtained from the developer section in your ImageKit dashboard.

In the python/sample.py file, set the following parameters for authentication:

from imagekitio import ImageKit
imagekit = ImageKit(
    private_key='your private_key',
    public_key='your public_key',
    url_endpoint = 'your url_endpoint'
)

To install dependencies that are in the python/requirements.txt file, can fire this command to install them:

pip install -r python/requirements.txt

Now run python/sample.py. If you are using CLI Tool (Terminal/Command prompt), open the project in CLI and execute it.

# if not installed already
pip install imagekitio

# if installing local sdk
pip install -e <path_to_local_sdk>

# to run sample.py file
