The third way of creating zones is by reading zones from a file (called a zone file) that contains the attributes of previously saved zones. An application can save the current zone definitions to a zone file any time with the ImGearRecZoneCollection.SaveToFile Method. The application can load them from a zone file with the LoadFromFile Method.

When a zone file is loaded, any previous zones on the image are removed.

If the application calls the ImGearRecPage.Recognize Method on an image with an empty zone list, the page-layout decomposition method is called automatically.
