A method for implementing dual-canvas mapping

Abstract

The invention discloses a double canvas mapping implementation method, and belongs to the technical field of handwriting display. An implementation device particularly comprises a handwriting capture device, a processing device, a caching device, a timing device and a display device. The implementation method includes the steps: performing a sliding operation on an upper display page by a user and capturing and processing a handwriting reserved by the sliding operation by the handwriting capture device; displaying the handwriting on the upper display page and transmitting the handwriting to the processing device by the handwriting capture device; exchanging the positions of a first display page and a second display page after finishing one sliding operation by the user; converting the handwriting into a background map and transmitting the background map to the upper display page to serve as the background of the upper display page by the processing device; backing up the background map and transmitting the background map to the caching device; and returning to the step a. The double canvas mapping implementation method has the advantages that a simple and clear handwriting environment is constantly kept on a handwriting interface, the processing procedure is accelerated, and the user obtains smooth operation experience.

Description

technical field [0001] The invention relates to the technical field of handwriting display, in particular to a dual-canvas mapping implementation method. Background technique [0002] With the continuous development of handwriting touch screen technology, people are more inclined to use electronic digital products with a handwriting touch screen. In these products, the function of capturing and displaying handwriting in real time can be realized. [0003] However, in the traditional handwriting capture implementation method, usually only one handwriting layer is used, and the handwriting left by the completed sliding operation and the handwriting left by the ongoing operation are displayed and saved in one layer, and the interface appears very Messy, at the same time, it will cause the processing time to be too long, resulting in shortcomings such as unsmooth handwriting. Contents of the invention [0004] According to the defects existing in the prior art, a method for i...
