Abstract
Methods, systems, and devices are described herein for rendering and blending variable opacity ink strokes on a touchscreen device. In one aspect, blending variable opacity ink strokes may include receiving a touch input including a stroke associated with variable opacity, and converting the stroke to a plurality of segments, including arc segments, line segments, or a combination thereof. Next, a plurality of stamps corresponding to the plurality segments may be generated and combined with a static texture and a varying texture. The plurality of stamps may be rendered on the touchscreen of the device to represent the stroke. In another aspect, the received stroke may at least partially overlap other visual data. In this case, the stamps associated with the stroke may be blended with the other visual data using source-over blending The blended plurality of stamps may be rendered on the touchscreen of the device to represent the stroke.
