Class AssumedObjectData

Namespace: Aspose.Imaging.Masking.Options
Assembly: Aspose.Imaging.dll (25.4.0)

The assumed object’s data. Includes object’s type and area.

public class AssumedObjectData

Inheritance

objectAssumedObjectData

Inherited Members

object.GetType(), object.MemberwiseClone(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()

Examples

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.

Saving image masking result with feathering based on image size and re-using masking options for the new masking iteration. 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. After getting initial masking result, applied background/foreground strokes are modified and another masking iteration is performed.

Saving image masking result with feathering based on image size, modifying obtained default strokes and using it for the new masking iteration. 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. After getting initial masking result, applied background/foreground strokes are modified and another masking iteration is performed using new GraphCutMaskingOptions instance.

Saving image masking result with feathering based on image size and re-using masking options for the new masking iteration. 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. After getting initial masking result, applied background/foreground strokes are modified and another masking iteration is performed.

Saving image masking result with feathering based on image size, modifying obtained default strokes and using it for the new masking iteration. 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. After getting initial masking result, applied background/foreground strokes are modified and another masking iteration is performed using new GraphCutMaskingOptions instance.
