Abstract

Techniques for assigning a subpath attribute to a subpath in a drawing are disclosed. One technique includes editing the drawing to define a current path having a current subpath, matching a previous vertex in a previous path with a current vertex in the current path, and assigning a current subpath attribute to the current subpath based on the vertex match. Another technique includes editing the drawing to define a current path having a current subpath, comparing the current subpath with a previous subpath having a previous subpath attribute, and assigning a previous subpath attribute to the current subpath based on the comparison.

Claims

1. A method of assigning a subpath attribute to a subpath in a drawing, including:

editing the drawing to combine a set of two or more previous subpaths into a current subpath, wherein each previous subpath is associated with a previous subpath attribute;

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

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

assigning to the current subpath the previous subpath attribute associated with the greatest total length; and

displaying the edited drawing.

2. A method as recited in claim 1, wherein at least one of the previous subpath attributes includes a color.

3. A method as recited in claim 1, wherein editing includes removing a path.

4. A method as recited in claim 1, wherein editing includes moving a path.

5. A method as recited in claim 1, wherein editing includes removing a path that intersects the set of two or more previous subpaths.

6. A method as recited in claim 1, wherein editing includes removing a path that separates the current subpath into the set of two or more previous subpaths.

7. A method as recited in claim 1, wherein editing includes merging the set of two or more previous subpaths into the current subpath.

8. A method as recited in claim 1, wherein editing includes merging the set of two or more previous subpaths into the current subpath in response to removing a path.

10. A method as recited in claim 8, wherein the previous subpath attribute includes a color.

11. A method as recited in claim 8, wherein editing includes adding a path.

12. A method as recited in claim 8, wherein editing includes moving a path.

13. A method as recited in claim 8, wherein editing includes adding a path that intersects with the previous subpath.

14. A method as recited in claim 8, wherein editing includes adding a path that divides the previous subpath into the two or more current subpaths.

15. A method as recited in claim 8, wherein editing includes dividing the previous subpath into the two or more current subpaths.

9. A method of assigning a subpath attribute to a current subpath in a drawing, including:

editing the drawing to divide a previous subpath into two or more current subpaths, wherein the previous subpath has a previous subpath attribute;

assigning the previous subpath attribute to each of the current subpaths; and

displaying the edited drawing.

16. A system for assigning a subpath attribute to a subpath in a drawing, including:

a processor configured to;

edit the drawing to combine a set of two or more previous subpaths into a current subpath, wherein each previous subpath is associated with a previous subpath attribute;

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

determine the previous subpath attribute associated with the greatest total length;

assign to the current subpath the previous subpath attribute associated with the greatest total length; and

display the edited drawing; and

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

17. A computer program product for assigning a subpath attribute to a subpath in a drawing, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

editing the drawing to combine a set of two or more previous subpaths into a current subpath, wherein each previous subpath is associated with a previous subpath attribute;

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

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

assigning to the current subpath the previous subpath attribute associated with the greatest total length; and

displaying the edited drawing.

18. A system for assigning a subpath attribute to a current subpath in a drawing, including:

a processor configured to;

edit the drawing to divide a previous subpath into two or more current subpaths, wherein the previous subpath has a previous subpath attribute;

assign the previous subpath attribute to each of the current subpaths; and

display the edited drawing.

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

19. A computer program product for assigning a subpath attribute to a current subpath in a drawing, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

editing the drawing to divide a previous subpath into two or more current subpaths, wherein the previous subpath has a previous subpath attribute;

assigning the previous subpath attribute to each of the current subpaths; and

displaying the edited drawing.
