Vector graph storage method used for handwriting signing system

Abstract

The invention discloses a vector graph storage method used for a handwriting signing system, and includes the steps of: obtaining vector points collected by a signer in touching of a screen; storing the collected plurality of vector points as a vector line, and generating a vector line location information; generating signing information in one-to-one correspondence with the vector line location information, and storing the vector line location information and the signing information in a vector graph JSON format; and uploading stored vector graph data to a server of the signing system. The method adopts a lightweight data exchange mode to describe vector graph information, greatly improves the speed of data analysis of a machine and network transmission speed, and also facilitates reading and compiling of ordinary people.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a vector graphics storage method used in a handwritten signature approval system. Background technique [0002] Paperless office systems are becoming more and more popular in governments and enterprises, and an important subsystem of paperless office systems is the workflow system. For better user experience, many workflow systems now add Added handwritten signature and approval function. [0003] Most of the existing handwritten approval systems use bitmaps for storage, and there are the following defects in using this method for graphics storage: 1. There is a problem that the file is too large during transmission. 2. It cannot be expanded according to business needs, and the correlation between documents and the workflow of the signing and approval system is poor. 3. It is impossible to directly trace the signer through the bitmap, and it must be supported by a thir...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing handwritten approval systems use bitmaps for storage. Using this method for graphics storage has the following defects: 1. There is a problem that the file is too large during transmission

2. It cannot be expanded according to business needs, and the correlation between documents and the workflow of the signing and approval system is poor

3. It is impossible to directly trace the signer through the bitmap, and it must be supported by a third-party tool

4. When zooming in, there will be a problem that the picture becomes blurred

[0007] 2. The next approver cannot modify the content of the handwritten approval of the previous one or more approvers, and the content of the approval can also control whether the next approver is visible or not

At the same time, professional software must be used to store and display, and these vector graphics storage and display technologies are not suitable for the special needs and needs of the handwritten approval system

[0017] To sum up, the existing technology lacks a vector graphics storage and editing method that meets the business requirements of the handwritten approval system, and the generated storage files are generally relatively large, which is not suitable for the business scenario of handwritten approval
