User interface for path distortion and stroke width editing
View Patent ↗A technique for modifying a stretch of path is disclosed. The technique includes receiving an indication of a drag gesture associated with a designated point on a path, identifying the first path corner or endpoint on either side of the designated point as limit points, defining a smooth stretch of the path as a portion of the path between the limit points, and modifying the smooth stretch of the path based on the drag gesture without modifying portions outside of the smooth stretch.
1. A system, comprising:
a processor configured to:
receive an indication of a drag gesture associated with a designated point on a path;
identify the first path corner or endpoint on each side of the designated point as limit points;
define a smooth stretch of the path as a portion of the path between the limit points; and
modify the smooth stretch of the path based on the drag gesture without modifying portions outside of the smooth stretch; and
a memory coupled to the processor and configured to provide the processor with instructions.
2. A system as recited in claim 1 , wherein the designated point is an unselected point.
3. A system as recited in claim 1 , wherein the designated point is on an unselected portion of the path.
4. A system as recited in claim 1 , wherein the drag gesture includes holding a mouse button down and dragging the mouse.
5. A system as recited in claim 1 , wherein the designated point is a point on the path within a selection tolerance of a mouse down point associated with the drag gesture.
6. A system as recited in claim 1 , wherein modify includes path modification.
7. A system as recited in claim 1 , wherein modify includes width modification.
8. A system as recited in claim 1 , wherein modify includes variable width modification.
9. A system as recited in claim 1 , wherein a corner is geometrically defined.
10. A system as recited in claim 1 , wherein a corner is defined based on an angle between tangents to points on either side of a given point.
11. A system as recited in claim 1 , wherein a corner is user defined.
12. A system as recited in claim 1 , wherein a modifier key is used in conjunction with the drag gesture.
13. A computer implemented method, comprising:
receiving an indication of a drag gesture associated with a designated point on a path;
identifying the first path corner or endpoint on either side of the designated point as limit points;
defining a smooth stretch of the path as a portion of the path between the limit points; and
modifying the smooth stretch of the path based on the drag gesture without modifying portions outside of the smooth stretch.
14. A method as recited in claim 13 , wherein defining a smooth stretch of the path is performed using a processor.
15. A method as recited in claim 13 , wherein the designated point is an unselected point.
16. A method as recited in claim 13 , wherein modifying includes path modification.
17. A method as recited in claim 13 , wherein modifying includes width modification.
18. A method as recited in claim 13 , wherein modifying includes variable width modification.
19. A method as recited in claim 13 , wherein a corner is geometrically defined.
20. A computer program product, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:
receiving an indication of a drag gesture associated with a designated point on a path;
identifying the first path corner or endpoint on either side of the designated point as limit points;
defining a smooth stretch of the path as a portion of the path between the limit points; and
modifying the smooth stretch of the path based on the drag gesture without modifying portions outside of the smooth stretch.
