/crop/auto-resize-align

Auto resize and align in Crop.photo, seamlessly resize and align your products within the frame while replacing the background with given color or background image.
This feature guarantees a polished appearance for a diverse range of products, including shoes, beverages, and home decor, enhancing the overall visual presentation.
Maintaining a consistent eye level significantly improves the browsing experience across various aspect ratios on your online storefront. The Auto Resize & Align API ensures precise alignment and sizing of the focal object, typically a product.

Example 1:
To resize the input image to a 2000x3000 dimension and automatically align the product in the center with uniform 8% margins around it, use the API as follows:

Body Params application/json

image_url

string <url>

required

Specifies the URL of the image. The URL should be a direct link to the image file, allowing the system to retrieve and process the image as needed.

The URL must be publicly accessible to ensure the system can retrieve the image without authentication barriers.

Supported image formats include .png, .jpg, .jpeg and .webp, etc. Ensure the URL points directly to a compatible image file.

Use a reliable hosting service to prevent issues with image availability or loading times.

This property is essential for operations that require an image as input, facilitating the integration of external images into the workflow.

Example:

https://acme.s3.aws.com/image.png

background

string

{#hex_code} - Allows setting the background to any custom color by providing a hex color code. For example, #FF5733 for a vibrant orange background.

{image_url} - Uses an image as the background by specifying its URL. Ensure the URL is accessible and the image format is compatible with your requirements.

none - Keep original background. Note: this option is not supported in all the APIs. Please read the documentation and try the APIs before using them in productions.
Note: Please note that the option none is only supported in the body-parts API and not in the auto-resize-align API.
