1. A method for controlling stroke rendering on a touch screen, the method comprising:
receiving indicia of pressure on a touch screen from a touch applied to the touch screen, where the pressure indicia represents an amount of force applied to the touch screen as the touch moves across a surface of the touch screen; iteratively computing, as the touch moves across the touch screen, a dot size as a summation of a minimum dot size and a pressure-based dot size increase, the pressure-based dot size increase corresponding to a difference between a current pressure indicia and a minimum pressure multiplied by a ratio of a maximum dot size to a maximum pressure; and rendering a newly created stroke on the touch screen along a path of the touch across the touch screen using the dot size computed during an immediately preceding iteration, wherein as the stroke is formed, the pressure indicia is computed and the stroke width is dynamically adjusted as the pressure indicia changes. |
