Abstract

A technique for editing is disclosed. The technique includes generating a path definition for a path, generating a plurality of subpath definitions of subpaths of the path based on an intersection of the path, associating the subpath definitions with the path definition, modifying the intersection of the path using an editing tool, and generating a plurality of modified subpath definitions of subpaths of the path based on the modified intersection of the path.

Claims

1. A method of editing, including:

generating a path definition for a path;

generating a plurality of subpath definitions of subpaths of the path based on an intersection of the path;

associating the subpath definitions with the path definition;

modifying the intersection of the path using an editing tool; and

generating a plurality of modified subpath definitions of subpaths of the path based on the modified intersection of the path.

2. A method as recited in claim 1, wherein modifying the intersection includes modifying the path definition.

3. A method as recited in claim 1, wherein modifying the intersection includes modifying another path definition.

4. A method as recited in claim 1, wherein modifying the intersection includes adding a new path definition.

5. A method as recited in claim 1, wherein modifying the intersection includes deleting another path definition.

6. A method as recited in claim 1, wherein modifying the intersection includes moving the path.

7. A method as recited in claim 1, wherein the intersection of the path is with itself.

8. A method as recited in claim 1, further including replacing the set of subpath definitions with the set of modified subpath definitions.

9. A method as recited in claim 1, wherein the subpath definitions include region attributes for each side of the subpaths.

10. A method as recited in claim 1, wherein the subpath definitions include region attributes for each side of the subpaths and further including deriving modified subpath region attributes for the modified subpaths based on the subpath region attributes.

11. A method as recited in claim 1, wherein the subpath definitions include subpath attributes.

12. A method as recited in claim 1, wherein the subpath definitions include subpath attributes and further including deriving modified subpath attributes for the modified subpaths based on the subpath attributes.

13. A method as recited in claim 1, wherein the subpath definitions include region attributes for each side of the subpaths and further including arbitrarily selecting modified subpath region attributes for the modified subpaths.

14. A method as recited in claim 1, wherein the subpath definitions include region attributes for regions on each side of the subpaths and further including merging two regions into a merged region, and deriving an attribute of the merged region based on the region attributes.

15. A method as recited in claim 1, wherein the subpath definitions include region attributes for regions on each side of the subpaths and further including:

merging two or more regions into a merged region;

determining for each region attribute the total area of the regions having that attribute;

determining the region attribute associated with the greatest total area; and

assigning to the merged region the region attribute associated with the greatest total area.

16. A method as recited in claim 1, wherein the modified subpath definitions include modified subpath attributes, and further including:

merging two or more subpaths into a merged subpath;

determining for each subpath attribute the total length of the subpaths having that attribute;

determining the subpath attribute associated with the greatest total length; and

assigning to the merged subpath the subpath attribute associated with the greatest total length.

17. A method as recited in claim 1, wherein the subpath definitions include region attributes for each side of the subpaths and further including deriving modified subpath region attributes for the modified subpaths based on the subpath region attributes, and reassigning at least one of the modified subpath region attributes.

18. A method as recited in claim 1, further including associating the modified subpath definitions with the path definition.

19. A method as recited in claim 1, further including marking the path definition as deleted.

20. A method as recited in claim 1, further including inserting a new path definition wherein the subpaths of the new path have the same attributes as one or more existing regions.

21. A method as recited in claim 1, further including determining a modified intersection by analyzing a portion of the drawing affected by the modification.

22. A method as recited in claim 1, wherein associating includes storing.

23. A system for editing, including:

a processor configured to;

generate a path definition for a path;

generate a plurality of subpath definitions of subpaths of the path based on an intersection of the path;

associate the subpath definitions with the path definition;

modify the intersection of the path using an editing tool; and

generate a plurality of modified subpath definitions of subpaths of the path based on the modified intersection of the path; and

a memory coupled with the processor, wherein the memory provides the processor with instructions.

24. A system as recited in claim 23, wherein the subpath definitions include region attributes for each side of the subpaths and wherein the processor is further configured to derive modified subpath region attributes for the modified subpaths based on the subpath region attributes.

25. A system as recited in claim 23, wherein the subpath definitions include subpath attributes and wherein the processor is further configured to derive modified subpath attributes for the modified subpaths based on the subpath attributes.

26. A system as recited in claim 23, wherein the processor is further configured to associate the modified subpath definitions with the path definition.

27. A computer program product for editing, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

generating a path definition for a path;

generating a plurality of subpath definitions of subpaths of the path based on an intersection of the path;

associating the subpath definitions with the path definition;

modifying the intersection of the path using an editing tool; and

generating a plurality of modified subpath definitions of subpaths of the path based on the modified intersection of the path.

28. A method of editing, including:

drawing a path;

modifying the path to include a plurality of subpaths; and

modifying the plurality of subpaths with a single edit action to the path.

29. A system for editing, including:

a processor configured to;

draw a path;

modify the path to include a plurality of subpaths; and

modify the plurality of subpaths with a single edit action to the path; and

a memory coupled with the processor, wherein the memory provides the processor with instructions.

30. A computer program product for editing, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

drawing a path;

modifying the path to include a plurality of subpaths; and

modifying the plurality of subpaths with a single edit action to the path.
