A method and system for realizing original handwriting

Abstract

The invention discloses a method and a system for implementing original handwriting. The method for implementing the original handwriting includes acquiring track coordinates of the handwriting in real time; computing the movement speed of the original handwriting according to horizontal coordinate position parameters and vertical coordinate position parameters which are acquired in real time; determining the widths of drawn tracks according to a preset pen type and acquired pressure parameters, using corresponding drawing points as starting points, filling track patterns with the corresponding widths in cross directions of forward directions of the tracks, dynamically adjusting the quantities of grids at the edges of the patterns according to the computed movement speed when the edges of the track patterns are drawn, and performing anti-aliasing processing on the edges of the track patterns according to the quantities of the grids at the edges of the track patterns. According to the technical scheme, the method and the system have the advantages that the quantities of the grids which are used for smoothly changing the edges of the track patterns are dynamically adjusted according to a handwriting movement speed characteristic of the original handwriting, so that the smoothness, the accuracy and the fluency of the track patterns are effectively balanced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of computer graphics processing, in particular to a method and system for realizing handwritten original handwriting. Background technique [0002] Due to the widespread use of touchpads in smart terminals, handwriting input has gradually become the mainstream input of smart terminals. Handwriting input imitates the process of writing on paper with a pen. Use your fingers or an electromagnetic pen to write on the touchpad, and you can get the expected writing symbols on the electronic device. The information transmitted from the touchpad to the main processor is a series of coordinate sequences. The process of the main processor drawing the input coordinate sequence into the writing symbols expected by the user is usually called original handwriting. [0003] In the original handwriting application, the coordinates passed from the touchpad to the host generally consist of three parameters x, y and p. x and y determi...

AI Technical Summary

Problems solved by technology

The more grids are reserved for smoothing, the greater the distance between the touchpad contact position and the current drawing position of the original handwriting track will make the user feel that the writing is lagging behind and affect the fluency of the original handwriting writing.

To sum up, the existing anti-aliasing processing cannot well balance the relationship between the smoothness, correctness and fluency of trajectory patterns
