public class AssumedObjectData
extends Object

Code example:

Saving image masking result with feathering based on image size. Image masking is performed using auto calculated default strokes. Additionally the data of the two assumed objects is also specified in the AssumedObjects property of the AutoMaskingGraphCutOptions.
