The Research Of Graphic Service Based On Scalable Vector Graphics

In recent years, distributed computing technology developed rapidly. The international software giants and the W3C have done much massive research on it. But, deciding from the digital standard and present application situation, we finded that we couldn't load multimedia information in WEB Service. How to load multimedia information in WEB Service was anxious in many applications. Seeking one appropriate graph expression way to be reasonable and not affect the current WEB Service application standard was quite practical and necessary.The W3C had formulated a network graph format----SVG in 1999. We may use code to construct a SVG graph dynamically to provide a "new" graph in time. The Web service could contain the SVG information by some appropriate way. After the client received the SVG information, they may use the DOM interface to do more editions conveniently or use it directly. Obviously this solving style would solve many problems when the Web service supply graph using the tradition way. In this article we mainly solved the following several aspects of the problem:(1) Through analyzing the characteristic, the realization way, the foundation agreement about the Web service, we talked about the scope of the Web service.(2) Through analyzing the form and the using way about the SVG, this article gave a suggestion how to use code to dynamically construct a SVG graph based on the XML technology.(3) This article solved how to contain the SVG information in the Web service and not have the influence to the present Web service application.(4) This article talked about how the client called the Web service which had contained the SVG information, and how the client processed the SVG information.(5) This article gave a suggestion how to do compression procession on the SVG when we wanted to transfer it in the Web Service efficiently.This paper's research was valuable for someone who wanted to construct a SVG dynamically, especially who wanted to load a graph in his Web service to provide a real time and alternative graph service. This paper's solving method was practicality and usable for this use.
