In Chinese culture,people have high requirements for the appearance of Chinese characters.With the development of computer hardware and software technology,various types of touch writing products have emerged at the historic moment.However,most of the Chinese characters written on the touch writing products currently on the market use linear link trace points,which are single and unsightly.People want to incorporate handwriting into touch writing products,so optimizing a single handwriting in this type of product has become a new market demand,and the beautification and rendering technology of computer handwriting has also received more and more attention.The method studied in this paper is to collect and recognize the track point information input by the handwriter on the touch screen to form the outline of the handwriting stroke with width information,and maximize the effect of restoring the shape of the handwriter's own font,so as to enable the handwriting input of users without basic calligraphy.It can also show fonts that are both beautiful and in different shapes.The method of realization is that on the existing touch all-in-one machine,based on the data of the contact movement speed at each instant when writing,the inclination angle of the handwriting and the real-time pressure of the contact,a trapezoidal model of the stroke is constructed between the two points,and the handwriting is designed on this model Generate an algorithm to track the contact trajectory of the pen and form a handwriting stroke outline with width information in real time,which not only retains the morphological characteristics of the handwriting font written by the writer himself,but also can beautify its shape,so that the handwriting input of users without basic calligraphy It can also show a writing effect that is both beautiful and individual.The method proposed in this paper solves the problem of single handwriting in the traditional touch screen,and the handwriting written on the touch screen isbeautiful and diverse.In response to the relevant key contents introduced above,the key work and main innovations made in this article are as follows.(1)For the first time,collect the speed,angle,pressure and other data of the contact movement in real time for the first time,add the factor that determines the width of the stroke presentation,calculate the width of the stroke presentation based on these data,and solve the problem The font handwriting brought by the slowness presents the problem that the width change is not obvious,and a more beautiful handwriting with a writing effect is obtained.(2)Designed a handwriting generation algorithm.By studying the stroke model,the method of simulating the writing related to the stroke model based on geometric modeling is summarized.After focusing on the character of regular script in traditional Chinese writing,a trapezoid model based on geometric modeling strokes was constructed,and a handwriting generation algorithm was designed based on this.Finally,script writing is generated.Through experiments,it is proved that the method of presenting the touch trajectory based on the brushstroke trapezoidal model as writing can achieve the effect of writing,and different users can present the writing with their own writing style.The method of presenting the touch trajectory based on the brush-trapezoidal model presented as writing in this paper has a good reference for other computer calligraphy algorithms.This subject is an exploration study with practical application value.
