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 computer-implemented 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 on the graphical user interface;

responsive to detecting the input to the shape, moving the shape, a child shape, and the buffer region according to a hierarchy of connected shapes, the child shape being connected to the shape and moving in accordance with constraints imposed by the shape until the child shape has been moved outside a snapping range;

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

displaying, on the graphical user interface, a subset of the set of drawing data that is located within the buffer region at a predetermined distance from the edge of the shape.

2. The computer-implemented method of claim 1, further comprising:

displaying a modifier key for the shape on the graphical user interface;

receiving an input to the modifier key; and

responsive to receiving the input to the modifier key, snapping the shape to one of a plurality of predetermined angles.

3. The computer-implemented method of claim 1, wherein the shape includes one or more drag points enabling manipulation of the shape responsive to detecting input at one or more of the drag points.

4. The computer-implemented method of claim 1, further comprising:

displaying a toggle switch on the graphical user interface;

detecting an input to the toggle switch; and

responsive to detecting the input to the toggle switch;

displaying a grid in the graphical user interface; and

constraining movement of the shape to defined increments along one or more axes of the displayed grid.

5. The computer-implemented method of claim 1, further comprising displaying the child shape and visually distinguishing the shape from the child shape.

6. The computer-implemented method of claim 1, further comprising:

detecting an input to the child shape, the input to the child shape initiating movement of the child shape; and

moving the child shape according to the input to the child shape without moving the shape.

7. The computer-implemented method of claim 1, further comprising:

detecting a touch input to the shape on the graphical user interface, the detected touch input to the shape initiating movement of the shape;

prior to release of the touch input;

moving the shape according to the touch input;

displaying, in a first visual depiction, a current position of the shape; and

displaying, in a second visual depiction, a subsequent position of the shape resulting from one or more constraints applied to the current position of the shape; and

upon release of the touch input, displaying the shape at the subsequent position resulting from the one or more constraints applied to the current position.

8. A system, comprising:

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

one or more processors to implement a computer application configured to;

detect an input to the shape on the graphical user interface;

move the shape, a child shape, and the buffer region according to a hierarchy of connected shapes in response to detecting the input to the shape, the child shape being connected to the shape and moving in accordance with constraints imposed by the shape until the child shape has been moved outside a snapping range;

receive a set of drawing inputs located within the buffer region and outside the buffer region; and

display a subset of the set of drawing inputs that are located within the buffer region at a predetermined distance from the edge of the shape on the graphical user interface.

9. The system of claim 8, wherein the system further includes a touch enabled input device, and the computer application is further configured to receive the set of drawing inputs from the touch enabled input device.

10. The system of claim 8, wherein the computer application is further configured to:

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

rotate the hierarchy of connected shapes on the graphical user interface responsive to the touch input.

11. The system of claim 8, wherein the display device is configured to display one or more moveable vanishing points for perspective drawing on the graphical user interface.

12. The system of claim 8, wherein:

the computer application is further configured to determine a second subset of the set of drawing inputs located at a distance from the edge of the shape that exceeds the predetermined distance; and

the display device is configured to display the second subset of the set of drawing inputs within the predetermined distance from the edge of the shape.

13. The system of claim 8, wherein the computer application is further configured to detect an input initiating movement of the child shape and move the child shape according to the input to the child shape without moving the shape.

14. In a digital medium environment in which a computing device provides a user interface for displaying drawing inputs, a non-transitory computer-readable storage medium storing instructions that are executable by the computing device to perform operations comprising:

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

detecting an input to the shape on the graphical user interface;

responsive to detecting the input to the shape, moving the shape, a child shape, and the buffer region according to a hierarchy of connected shapes, the child shape being connected to the shape and moving in accordance with constraints imposed by the shape until the child shape has been moved outside a snapping range;

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

displaying a subset of the set of drawing data that is located within the buffer region at a predetermined distance from the edge of the shape on the graphical user interface.

15. A non-transitory computer-readable storage medium as described in claim 14, the operations further comprising:
