Length Out of Intersection property

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

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

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

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