A reflow tool employs layout information from an ink analyzer to determine a relationship between different units of electronic ink, such as words. The reflow tool then collects this relationship information into an ink relationship data structure for later use. When the reflow area containing the electronic ink is resized, or when an edit space is inserted into or deleted from the electronic ink, the reflow tool uses the relationship information from the data structure to intelligently segment the electronic ink for reflow. In this manner, the reflow tool ensures that units of electronic ink, such as words, which are associated with larger groupings of electronic ink, such as paragraphs, are not segmented from those larger groupings to which they belong.
