Abstract

A graphical user interface displays a shape. Further, a buffer region that is adjacent to an edge of the shape is displayed at the graphical user interface. In addition, a set of drawing data located within the buffer region is received from a user input device. A first subset of the drawing data that is located in the buffer region at a predetermined distance from the edge and a second subset of the drawing data in the buffer region that is located at a distance from the edge that exceeds the predetermined distance are determined with a processor. Further, the first subset of drawing data is displayed. In addition, the second subset of drawing data is prevented from being displayed at the distance. The process also displays the second subset of drawing data at the predetermined distance.

Claims

1. A non-transitory computer useable storage memory having executable program instructions stored thereon that, responsive to execution by a computing device, cause the computing device to:

display a shape and a buffer region adjacent to an edge of the shape on a graphical user interface;

receive, from an input device, a set of freeform drawing data located within the displayed buffer region;

detecting an edge touching subset of the freeform drawing data, the edge touching subset including freeform drawing data that is touching an edge of the shape and, responsive to said detecting, providing a visual indication that the edge touching subset of the freeform drawing data is touching the shape;

determine a first subset of the freeform drawing data located within a predetermined distance from the edge of the shape;

determine a second subset of the freeform drawing data located at a distance from the edge of the shape that exceeds the predetermined distance;

display the first subset of the freeform drawing data;

prevent the second subset of the freeform drawing data from being displayed at the distance from the edge of the shape that exceeds the predetermined distance;

display the second subset of the freeform drawing data repositioned within the predetermined distance; and

move the shape according to a hierarchy of connected shapes, the shape being a root shape connected to a child shape and the root shape dictates a movement behavior of the child shape.

2. The non-transitory computer useable storage memory of claim 1, wherein the input device is a touch enabled device.

3. The non-transitory computer useable storage memory of claim 2, wherein the program instructions are further executable by the computing device to move the shape responsive to detection of a touch input.

4. The non-transitory computer useable storage memory of claim 3, wherein the program instructions are further executable by the computing device to rotate the shape responsive to detection of a second touch input.

5. The non-transitory computer useable storage memory of claim 1, wherein the shape has one or more drag points enabling manipulation of the shape responsive to detection of an input at one or more of the drag points.

6. The non-transitory computer useable storage memory of claim 1, wherein the program instructions are further executable by the computing device to:

display a modifier key on the graphical user interface; and

responsive to detection of an input to the modifier key, snap the shape to an angle.

7. The non-transitory computer useable storage memory of claim 1, wherein the program instructions are further executable by the computing device to display one or more moveable vanishing points of the shape for perspective drawing.

8. The computer useable storage memory of claim 1, wherein the program instructions are further executable by the computing device to display a drawing support tool on the graphical user interface.

9. A method comprising:

displaying a shape and a buffer region that is adjacent to an edge of the shape on a graphical user interface;

detecting an input to the shape;

responsive to detecting the input to the shape, displaying one or more snapping locations within the buffer region;

receiving a set of drawing data located within the buffer region;

determining a first subset of the drawing data located within a predetermined distance from the edge of the shape;

determining a second subset of the drawing data located at a distance from the edge of the shape that exceeds the predetermined distance;

displaying the first subset of the drawing data;

preventing the second subset of the drawing data from being displayed at the distance from the edge of the shape that exceeds the predetermined distance;

displaying the second subset of the drawing data at one of the one or more displayed snapping locations within the predetermined distance; and

moving the shape according to a hierarchy of connected shapes, the shape being a root shape connected to a child shape and the root shape dictating a movement behavior of the child shape.

10. The method of claim 9, wherein the set of drawing data is received from an input device that is a touch enabled device.

11. The method of claim 10, further comprising:

detecting a touch input to the shape on the graphical user interface; and

moving the shape responsive to said detecting the touch input.

12. The method of claim 11, further comprising:

detecting an additional touch input to the shape on the graphical user interface; and

rotating the shape responsive to said detecting the additional touch input.

13. The method of claim 9, wherein the shape has a plurality of drag points enabling manipulation of the shape responsive to detecting input at one or more of the plurality of drag points.

14. The method of claim 9, further comprising:

displaying, at the graphical user interface, a modifier key; and

responsive to detecting input at the modifier key, snapping the shape to an angle.

15. The method of claim 9, further comprising displaying one or more moveable vanishing points for perspective drawing.

16. The method of claim 9, further comprising displaying a drawing support tool.

17. A system comprising:

a memory configured to maintain drawing data;

a display device configured to display a shape and a buffer region adjacent to an edge of the shape on a graphical user interface, the shape including a separate user interface on its surface displaying one or more selectable preset shapes; and

one or more processors to implement an edge detection module that is configured to;

receive, at the separate user interface, a selection of one of the one or more preset shapes;

responsive to receiving said selection, change the displayed shape to the selected one of the one or more preset shapes;

receive a set of the drawing data located within the buffer region;

determine a first subset of the drawing data located within a predetermined distance from the edge of the preset shape;

determine a second subset of the drawing data located at a distance that exceeds the predetermined distance;

initiate a display of the first subset of the drawing data;

prevent the second subset of the drawing data from being displayed at the distance that exceeds the predetermined distance;

initiate a display of the second subset of the drawing data repositioned within the predetermined distance; and

move the preset shape according to a hierarchy of connected shapes, the preset shape being a root shape connected to a child shape and the root shape dictates a movement behavior of the child shape.

18. The system of claim 17, wherein the edge detection module is configured to said receive the set of the drawing data via an input device that is a touch enabled device.

19. The system of claim 18, wherein the edge detection module is configured to move the shape responsive to detection of a touch input to the shape.

20. The system of claim 19, wherein the edge detection module is configured to rotate the shape responsive to detection of an additional touch input to the shape.
