Abstract:
1. A computer-implemented method comprising: receiving a first user input selecting a path of a paint stroke rendered on a display; defining, by a data processing apparatus, an anchor point on the paint stroke path based on the first user input; rendering, by the data processing apparatus, a characteristic adjustment control adjacent to the anchor point, the characteristic adjustment control including a first drag point handle aligned along an axis that passes through the characteristic adjustment control and forms an angle with the paint stroke path, the first drag point handle including a sub-handle, wherein the first drag point handle and the sub-handle are configured to adjust characteristics of the paint stroke in response to user input; receiving, by the data processing apparatus, a second user input via the characteristic adjustment control, the second user input including an input to the sub-handle; and adjusting, by the data processing apparatus, a characteristic of the paint stroke at the anchor point based on the second user input.
