Method for describing and reproducing on-line vector diagram modeling process

Abstract

The invention discloses a method for describing and reproducing an on-line vector diagram modeling process. The description of the modeling process is high-fidelity, on one hand, the extracted operation with modeling semantics can reflect the connotation of all or most of low-level events, and on the other hand, the redundant operation is required to be filtered; the reproduction of the modeling process is adaptive, on one hand, since an on-line application is updated continuously, the reproduction of the modeling process can adapt the changes to enhance the robustness and the practicability of the application, and on the other hand, the reproduction of the modeling process can be conveniently modified and multiplexed. The description is abstract description for graphic operation, and the requirement on bandwidth is low; the method has certain adaptation to change of a webpage version and can meet the requirement on timeliness of version evolution; the reproduced operation is actual operation for an actual model, and a user can very easily modify and extend the model to achieve multiple purposes; the implementation modes comprise an embedded mode and an extended mode, and the universality is high.

Description

technical field [0001] The invention relates to vector diagram modeling, in particular to a description and reproduction method of an online vector diagram modeling process. Background technique [0002] Vector graphics draw graphics according to geometric characteristics. Vectors can be a point or a line. Vector graphics can only be generated by software, and the internal space of the file is small, because this type of image file contains independent separate images, which can be freely and freely Restricted regrouping. Its feature is that the image will not be distorted after being enlarged, and it has nothing to do with the resolution. It is suitable for graphic design, text design, some logo design, layout design, etc. [0003] Scalable Vector Graphics (SVG) is a graphic format for describing two-dimensional vector graphics based on Extensible Markup Language (a subset of Standard General Markup Language). It was developed by the World Wide Web Consortium and is an op...

AI Technical Summary

Problems solved by technology

[0009] (1) Large storage space: The size of ordinary format video generally ranges from several hundred MB to several GB, which is not conducive to transmission due to bandwidth, speed and other restrictions in the existing network environment;

[0010] (2) The clarity cannot be guaranteed: using compression technology to reduce the video file size will result in a decrease in resolution, and the video clarity cannot be guaranteed;

[0011] (3) Lack of timeliness: After the video is recorded, the online website may be updated at any time, causing the video to lose timeliness, thus increasing the cost of production and maintenance;

[0012] (4) Lack of scalability: video recording is only a reproduction of the scene, it does not allow users to perform subsequent expansions, and does not support users' changes to the real model, so it lacks scalability

[0014] (1) Lack of support for graphics features: CoScripter only supports the reproduction of the processing process of page forms (such as text boxes, buttons, etc.), but cannot support the operation of vector graphics, because graphics operations involve more underlying events and operation semantics more complicated;

[0015] (2) Lack of adaptation to page changes: the webpage is likely to be continuously upgraded, and the described page operations should also have certain adaptability to webpage changes

CoScripter does not currently address the situation where the page keeps changing
