Notice

  • The URL of the result image is valid for 1 hour. Please download the image file promptly.

  • You need to mark the area to be removed before starting the auto-removal. Mask Image and Rectangles are available for masking unwanted areas. For a Mask Image, the image size is the same as the source image. The removal area is white, and the rest of the area is black (as shown below). Please note that the removed area should not be larger than 50% of the source image. See the details in API Reference.
