Abstract
A method includes displaying a drawing aid in a sketch area on a touch-sensitive display, and receiving one or more drawing inputs. In response to receiving the one or more drawing inputs, the device displays marks based on the drawing inputs that are constrained based on the drawing aid. While displaying the drawing aid in the sketch area, the device detects a touch gesture at a location corresponding to a location of the drawing aid. In response to detecting the touch gesture: if the touch gesture is a pinch gesture, the device ceases to display the drawing aid in the sketch area; and if the touch gesture is a rotational gesture, the device rotates the drawing aid relative to the sketch area in accordance with the movement of at least one contact in the touch gesture while maintaining display of the drawing aid in the sketch area.
