The mapper is used by this container when converting display, container and image coordinates. For more information, refer to AnnContainerMapper.
If you set the value of this property to null, then this container will use an object created from AnnContainerMapper.CreateDefault instead. Therefore, you will always get a valid object when querying the value of this property.
