Problems solved by technology

[0003] Moreover, in the existing method of simulating the shape of a brush on a touch screen, the pen-shaped lines formed by sequentially connecting touch points in a straight line often have obvious and abrupt turning points at the joints, which do not conform to the actual drawing effect of the brush and are realistic. degree is not high

Abstract

The invention provides a chirography drawing method and a chirography drawing device. The chirography drawing method comprises the following steps that: when chirography drawing is carried out on a touch screen, obtaining and storing the coordinate value of each touch point on the chirography; after two initial touch points are obtained and before the last touch point is obtained, when one touch point is obtained, solving a pen type connection equation between the current touch point and a previous touch point adjacent to the current touch point; according to a preset abscissa calculation formula and the pen type connection equation, calculating the coordinate value of each connection point in the connection point inserted between the current touch point and the previous touch point; and carrying out line connection on the current touch point, the previous touch point and each connection point. Through the technical scheme, each touch point in a chirography drawing process can be smoothly connected, so that a formed line junction does not have an obvious abrupt turn, chirography drawing fidelity is improved, and user experience is improved.

Description

Technical field [0001] The invention relates to the technical field of computer graphics processing, in particular to a handwriting drawing method and a handwriting drawing device. Background technique [0002] At present, with the continuous development of touch screen technology, most existing smart terminals use touch screens. The user can interact with the smart terminal through the touch screen to conveniently complete the operation of the smart terminal. In addition, various applications for smart terminals have also been widely developed. Take the application that can draw on the smart terminal (APP for short) as an example. The user can download and install the drawing APP from the application provider. When you need to use the painting APP, you can open the painting APP to enter the operation interface. On the operation interface, the user can operate on the touch screen with fingers to draw various patterns or write letters. [0003] Moreover, in the existing method of ...
