Writing note data storage method and device, terminal and storage medium

Abstract

The invention discloses a writing note data storage method and device, a terminal and a storage medium. The method comprises the following steps of receiving a writing operation of a user on a canvas;displaying a corresponding writing handwriting on the canvas according to the writing operation; and when a storage operation used for storing the writing handwriting on the canvas is detected, generating a writing handwriting file according to the canvas and the writing handwriting, so that when the writing handwriting file is opened, the corresponding writing handwriting is displayed and the writing handwriting file is transmitted, wherein the writing handwriting file comprises at least two levels, different data blocks in each level are separated by a special character, and special characters of different levels are different. According to the method and the device, the data amount of the generated writing handwriting file can be reduced on the premise of keeping the edibility of handwriting data, so that the required storage space is reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a writing note data storage method, device, terminal and storage medium. Background technique [0002] The popularity of touch screens has greatly improved human-computer interaction, especially human-computer writing. Based on touch screen technology, users can freely draw, paint, and write on the touch screen, and the corresponding handwriting will be generated on the touch screen, and after the user finishes writing, the handwriting can also be saved for future use. Modifying, disseminating or reproducing the user's writing or drawing process at one time, which is very helpful for the reproduction and description of creation.
