Method for generating stroke and processing device for generating stroke

Abstract

The invention discloses a method for generating a stroke and a processing device for generating stroke, and belongs to the technical field of electronic handwriting. The method comprises the followingsteps: obtaining and storing a coordinate value of each touch point and the number n of the touch points; and when n is greater than or equal to 4, calculating the width values of the last four touchpoints, drawing a contour line according to the coordinate values and the width values of the last four touch points, and filling a blank area surrounded by the contour line according to a preset color to obtain a pen point. The processing device for generating the stroke comprises an acquisition module, a calibration module, a calculation module and a processing module, the calculation module and the acquisition module are connected with the calibration module, and the calculation module and the drawing module are connected with the processing module. The invention aims to overcome the defect that in the prior art, the electronic handwriting is lack of the pen point, the pen point of the handwriting can be generated, and the generated pen point can have a better simulated writing effect.

Description

technical field [0001] The invention relates to the technical field of electronic handwriting, and more specifically, to a method and a processing device for generating strokes. Background technique [0002] Along with popularizing of computer equipment, utilizing computer equipment to carry out character input has become a part of people's daily life. In the field of interactive smart panels, handwriting function, as one of the more and more important functions of interactive smart panels, has been widely used in people's work and study, which greatly improves people's work and study effects; users can Drawing and writing operations are performed by touching or writing tools on the operation interface of the electronic device. For example, in a teaching scenario, a teacher can write in handwriting on the current interactive smart tablet, and students can watch the handwriting written by the teacher through the interactive smart tablet. [0003] At present, the traditional...

Problems solved by technology

The method includes: acquiring a touch point; the touch point is a plurality of points triggered by handwriting events on the interactive smart flat touch screen; calculating the width of the touch point, and the skeleton line of the handwriting corresponding to the touch point; determining the outline of the handwriting; the outline is based on The width of the touch point is calculated; get the inflection point in the contour line, and generate the Bezier curve corresponding to the inflection point as the smoothed contour line; the direction of the Bezier curve is determined by the direction of the skeleton line; draw according to the smoothed contour line Handwriting; although this scheme can generate strokes, the disadvantage of this scheme is that the calculation amount is large and the calculation method is relatively complicated
