Abstract

The invention relates to a handwriting rendering method, a device, an interactive intelligent tablet computer and a storage medium, which are applied to the interactive intelligent tablet computer. The method comprises the following steps of: acquiring a touch point; the touch point is a plurality of points triggered by a handwriting event on an interactive intelligent tablet touch screen; calculating a width of the touch point and a skeleton line of the handwriting corresponding to the touch point; determining the outline of the handwriting; calculating the contour line according to the widthof the touch point; obtaining an inflection point in the contour line and generating a Bezier curve corresponding to the inflection point as a smoothed contour line; determining the direction of theBezier curve by the direction of the skeleton line; drawing the handwriting according to the smooth contour. The embodiment of the invention solves the problem that the edge of the drawn handwriting is relatively stiff, and improves the handwriting effect based on an interactive intelligent tablet computer.

Description

technical field [0001] The invention relates to the technical field of interactive smart panels, in particular to a handwriting drawing method and device on an interactive smart panel, an interactive smart panel and a storage medium. Background technique [0002] In the field of interactive smart panels, handwriting function, as one of the more and more important functions of interactive smart panels, has been widely used in people's work and study, which greatly improves people's work and study effects. For example, in a teaching scenario, a teacher can write in handwriting on the current interactive smart tablet, and students can watch the handwriting written by the teacher through the interactive smart tablet. [0003] The handwriting function can be realized through the software and related hardware in the interactive smart tablet. After the touch screen detects the handwriting event, the touch screen hardware collects the touch information and sends it to the system in ...
