Abstract
Methods, systems, and devices are described herein for rendering variable opacity ink strokes on a touchscreen device. In one aspect, a method for rendering variable opacity ink strokes includes receiving a touch input including a stroke associated with variable opacity on a touchscreen of a device. The stroke may be converted to at least one Bezier curve. The at least one Bezier curve may be smoothed and dividing into a plurality of segments, wherein the plurality of segments includes arc segments, line segments, or a combination thereof. A plurality of stamps may be generated corresponding to the plurality of segments. The plurality of stamps may be rendered on the touchscreen of the device to represent the stroke.
