FAQ

1. What is the strategy for the Image Cropping product?

Image Cropping can automatically identify the main subject in the picture. It then crops the image to the input target size while preserving as much of the subject as possible.

2. Will cropping damage the main part of the product?

Cropping might damage the main subject when the picture contains multiple subjects or when the target aspect ratio significantly differs from the original image's aspect ratio.

3. Can the cropping specify the area or content to be retained?

No. Cropping is based on the identified complete main subject. It is not possible to specify retaining certain local areas or content.

4. What should I do if an error occurs?

Please refer to the "Errors" section of the API reference for possible causes and recommended solutions.
