Abstract

The present application provides a method and device for displaying handwriting. The method includes: collecting touch points in real time during the sliding process of the touch component on the touch screen; The allocated radius builds a circle; if there are already collected touch points, determine the outer common tangent between the currently collected touch point and the circle to which its adjacent touch points belong, and determine the closed area composed of the outer common tangent and the two circles Render and display the handwriting between two touch points. By assigning a radius to the touch point and constructing a circle, and constructing the shape of the stroke in segments, that is, for every two adjacent touch points, the rendering displays a closed area composed of a common tangent and two circles, since each segment is a simple and It is easy to draw closed-area graphics, so the implementation complexity is relatively low, and the entire implementation process does not depend on the hardware support of the pressure sensor or speed sensor on the device, and is applicable to any device with a touch screen.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a handwriting display method and device. Background technique [0002] With the rapid development of electronic technology, people rely more and more on various electronic devices. They often need to input information by handwriting on electronic devices, and even use electronic devices to realize the display of stroke effects of various pen types (such as pencils, pens, brushes, etc.) , especially the realization of brush stroke effect. [0003] In order to realize the stroke effect of the brush on the electronic device, some current technologies determine the width of the handwriting according to the touch pressure detected by the sensor, or determine the width of the handwriting according to the sliding speed detected by the sensor, so as to achieve the stroke effect. However, these methods all need to rely on the hardware support of the electronic device. If the ...
