Abstract

Methods for classifying, anchoring, and transforming ink are disclosed. Ink drawings and ink annotations are captured and stored with additional information that allows the various described methods to associate the ink with one or more displayed elements. During reformatting or re-flowing a displayed document, the ink may be properly displayed as originally intended.

Claims

1. A computer-implemented method for adding electronic ink to displayed information on a system having a display, said method comprising the steps of:

classifying said electronic ink based on a shape of said electronic ink;

associating said classified electronic ink with at least one object of said displayed information;

wherein said classifying step includes the step of determining said electronic ink'"'"'s distance to other annotations.

2. The method according to claim 1, wherein said associating step further includes the step of:

anchoring said electronic ink to a file position of said at least one object.

3. The method of claim 1, wherein said step of classifying including classifying said electronic ink as a chain of strokes and said associating step includes associating a center of said chain of strokes with said at least one object.

4. A computer-implemented method for adding electronic ink to displayed information on a system having a display, said method comprising the steps of:

classifying said electronic ink based on a shape of said electronic ink;

associating said classified electronic ink with at least one object of said displayed information;

wherein said classifying step includes the step of determining the ratio of said electronic ink height to width.

5. The method according to claim 4, wherein said associating step further includes the step of:

anchoring said electronic ink to said at least one object by adding a link to said displayed information.

6. The method according to claim 4, wherein said classifying step classifies said ink as text marks.

7. The method according to claim 4, wherein said classifying step classifies said ink as in-line paragraphs and sketches.

8. The method according to claim 4, wherein said classifying step classifies said ink as margin notes.

9. The method according to claim 4, wherein said classifying step classifies said ink as a connector.

10. A computer-implemented method for adding electronic ink to displayed information on a system having a display, said method comprising the steps of:

classifying said electronic ink;

associating said electronic ink with at least one object of said displayed information, wherein the relationship of said electronic ink to said at least one object is maintained despite re-flowing of said displayed information by a layout engine.

11. The method according to claim 10, wherein said classifying step classifies said ink as in-line words in which said at least one object is within a flow of text.

12. A computer readable medium having a program stored thereon, said program implementing a method for adding electronic ink to displayed information on a system having a display, said program comprising the steps of:

classifying said electronic ink based on shape of the electronic ink;

associating said classified electronic ink with at least one object of said displayed information;

wherein said classifying step includes the step of determining its distance to other annotations.

13. The computer readable medium according to claim 12, wherein said classifying step classifies said electronic ink as one of embedded ink and overlaid ink.

14. The computer readable medium according to claim 12, wherein said associating step further includes the step of:

anchoring said electronic ink to said at least one object by adding a link to said displayed information.

15. A computer readable medium having a program stored thereon, said program implementing a method for adding electronic ink to displayed information on a system having a display, said program comprising the steps of:

classifying said electronic ink based on shape of the electronic ink;

associating said classified electronic ink with at least one object of said displayed information;

wherein said classifying step includes the step of determining the ratio of said electronic ink height to width.

16. The computer readable medium according to claim 15, wherein said associating step further includes the step of:

anchoring said electronic ink to a file position of said at least one object.

17. The computer readable medium according to claim 15, wherein said associating step further includes the step of:

anchoring said electronic ink to said at least one object by adding a link at or near said object pointing to said electronic ink.

18. The computer readable medium according to claim 15, wherein the relationship of said electronic ink to said at least one object is maintained despite re-flowing of said displayed information by a layout engine.

19. The computer readable medium according to claim 15, wherein said classifying step classifies said ink as in-line words in which said at least one object is within a flow of text.

20. The computer readable medium according to claim 15, wherein said classifying step classifies said ink as text marks.

21. The computer readable medium according to claim 15, wherein said classifying step classifies said ink as in-line paragraphs and sketches.

22. The computer readable medium according to claim 15, wherein said classifying step classifies said ink as margin notes.

23. The computer readable medium according to claim 15, wherein said classifying step classifies said ink as a connector.
