Abstract:
1. A method for implementing an original handwriting trace, characterized in that it includes implementation of an intersection point between two intersected strokes by: a step of determining a stroke width, in which a handwriting trace is sampled continuously and adjacent sampling points are determined according to the sampling time order, with the former one of the adjacent sampling points is determined as a starting sampling point and the latter one of the adjacent sampling points is determined as an ending sampling point; and pressure values and position information of the respective sampling points are detected, and actual stroke widths at the sampling points are determined according to the respective pressure values; a step of setting a main line, in which a line from the starting sampling point to the ending sampling point is used as a central line of the stroke between the two adjacent sampling points, the position information of and a longitudinal stroke width at each point on the central line are obtained, and one of the central lines of the two intersected strokes is set as the main line in the x-axis direction; a step of determining, in which filling gray values for pixels corresponding to the intersection point between the two intersected strokes are calculated, according to the position information of and the longitudinal stroke width at each point on the central lines of the two intersected strokes, as well as slopes of the central lines of the two intersected strokes and orientation of the two intersected strokes; and a step of displaying, in which the corresponding pixels are filled according to the filling gray values and displayed.
