Creation and manipulation of hand drawn objects with automatic grouping |
摘要 |
A graphical drawing includes maintaining recently drawn strokes in a wet state after the strokes are drawn, causing strokes in a wet state to transition to a dry state based on passage of time, proximity of other recently drawn strokes, and/or explicit user input directing that at least some wet strokes be transitioned to the dry state, and grouping strokes in the dry state for future user manipulation based at least in part on how the strokes transitioned from the wet state to the dry state. Wet ink strokes may transition from the wet state to the dry state in response to not adding any new wet ink strokes for a predetermined amount of time. The predetermined amount of time may be twelve hundred milliseconds. |

1. A method of drawing on a touch screen input of a device, comprising:
maintaining recently drawn strokes in a wet state after the strokes are drawn on the touch screen input of the device; causing strokes in a wet state to transition to a dry state based on at least one of: passage of time, proximity of other recently drawn strokes, and explicit user input directing that at least some wet strokes be transitioned to the dry state; grouping strokes in the dry state for future user manipulation based at least in part on how the strokes transitioned from the wet state to the dry state; and causing strokes in the dry state to transition back to the wet state, wherein drawing operations do not effect ink in the wet state that was transitioned from the dry state. |
