Method and system for conducting drawing on touch screen to achieve writing brush effect

Abstract

The invention discloses a method and system for conducting drawing on a touch screen to achieve the writing brush effect. The method includes the steps that a track that a user moves brush marks on the touch screen is acquired, and information of sampling points is acquired; interpolating points between every two adjacent sampling points are calculated; according to the information of the sampling points, the moving speed of brush marks between every two adjacent sampling points is calculated; according to the moving speed of the brush marks, the scaling of brush mark bit maps between every two adjacent sampling points is determined; according to the scaling, original brush bit maps are scaled and then drawn to the corresponding sampling points and the corresponding interpolating points, and then writing brush marks between every two adjacent sampling points are acquired. By the utilization of the method and system, the writing brush marks drawn on the touch screen can be smooth and continuous, and then the good handwriting effect is displayed.

Description

technical field [0001] The invention relates to the technical field of handwriting input, in particular to a method and system for drawing brush effects on a touch screen. Background technique [0002] The writing brush is a unique writing tool in China, which has lofty value in the history of Chinese culture and art. Its strokes are rich in expression and difficult to control, which is difficult for any other writing tools to achieve. In today's digital era, people began to imagine that the rich expressiveness of the brush can be brought to the digital field, and while inheriting this great art, it has also been further developed. [0003] In the prior art, the method of simulating writing with a brush mainly uses hardware to obtain input data, and corrects these data through software algorithms to achieve the effect of writing with a brush and achieve the purpose of simulating real brush actions. In these implementation methods, hardware equipment dedicated to writing wi...

AI Technical Summary

Problems solved by technology

In these implementation methods, hardware devices dedicated to writing with a brush are required, and the cost of the devices is high.

Moreover, due to the soft tip of the brush, the degree of lifting and pressing of the pen during writing, the change of the direction of the pen, etc., will all have an impact on the change of the writing. When the touch pen moves on the screen of the device, the device will notify the corresponding processing software of the current position, pressure, time, slope rate and other information of the touch pen in the form of touch events. The limitations of the ability and event notification mechanism make the handwriting display effect poor and cannot better reflect the calligraphy art of the brush
