Abstract

The invention discloses a handwriting data caching method, device, equipment and storage medium, and relates to the technical field of smart panels. The method includes: generating handwriting according to a touch action on a display interface, and acquiring the handwriting on the display interface; according to the writing state of the handwriting, Generate handwriting data, the handwriting data includes process data and result data, the result data saves the final display state of the handwriting; send the handwriting data to the writing buffer in sequence. Adopting the above method can solve the technical problem that the server side simultaneously caches and parses the handwriting data in the prior art, which increases the complexity and instability of the system logic, and realizes the synchronization of the handwriting content of the newly connected client in a simple and effective manner.

Description

technical field [0001] The embodiment of the present invention relates to the field of multimedia technologies, and in particular to a handwriting data caching method, device, device and storage medium. Background technique [0002] In the existing synchronous writing whiteboard system, it includes at least two display terminals and a server. When the user writes in the display terminal A, the display terminal A records all the coordinate points written by the user and uploads the newly generated coordinate points in real time. To the server, the server transfers the newly generated coordinate points to another display terminal B, and the display terminal B then restores and draws according to the transferred coordinate points, so as to realize the synchronous display of the content written by the user remotely on another terminal. [0003] In the application of the synchronous writing whiteboard system, in order to restore and display the handwriting data before logout afte...
