Length of Argument Features Out of Intersection property

This property is defined for the same feature types as Intersection Length of Argument Features property, i.e. for intersection of area, text and image feature with area, text, image and line argument features.

The value of this property for area, text or image argument feature is defined as total length of all argument feature's boundaries with the exception of those segments which are located within the tested feature.

For a line argument feature the property's value is defined as the length of that part of argument which does not belong to the inner region of the tested feature.

In other words, the length of an argument feature out of intersection is always equal to the total length of the argument feature minus the length of its intersection with the tested feature.
