Abstract
A method and apparatus for editing a scanned image. The present invention provides for editing of a scanned image in terms of interpretations of graphical objects contained therein. A graphical object can represent a letter, word, line of text, graphic or any other portion of the document image selected by the user. An interpretation embodies a predetermined relationship between graphical objects as well as editing operations that can be performed on the graphical objects. Interpretations belong to one of two classes. A first class, set interpretation, treats graphical objects as an unordered set lying within a document plane. Editing operations in a set interpretation allow a graphical object to be manipulated within in the document plane without disturbing the spatial orientation of other graphical objects. A second class, sequence interpretation, is like a set interpretation except that the set of graphical objects are ordered. An editing operation in a sequence interpretation will typically affect the spatial orientation of other graphical objects in the set of graphical objects. A particular type of sequence interpretation, called text interpretation, allows for manipulation of sets of graphical objects as if they were text.
