【摘要】 SVG (Scalable Vector Graphics,可升级矢量图像)是由国际WWW委员会(W3C )组织为适应Internet Web应用的飞速发展需要而制定的一套基于XML语言的可缩放矢量图形语言描述规范。SVG可在网页上显示出高质量的图形,集矢量图形与XML优点于一身,既有矢量图形的图形文件简洁,图像品质高,可无级缩放等优点,又继承了XML的跨平台性和可扩展性。SVG克服了现有的基于象素的Web上的图形的缺点并且很好的融合了传统Web的标准,同时弥补了Web图形在动态性和交互式能力方面的不足。随着SVG逐渐成为网络中矢量图形的业界标准,SVG的应用领域也不断扩展。本文设计并实现了基于Web的跨平台的水电站系统软件。论文详细阐述了SVG及网络服务器开发技术。分析了和比较了几种Web应用软件体系结构,并将基于SVG的三层软件体系结构作为本文指导思想,通过软件编程实现了系统各部分功能模块。最后介绍了系统的运行环境,并详细阐述了实现系统的关键技术问题。该系统具有浏览速度快、页面无闪烁、交互性强、易于移植和扩展等多种优点,能够较好地解决实际问题。系统采用SVG,XML以及DOM等W3C标准和JSP技术,因此解决方案可以推广应用到各种操作系统平台以及相关的需求中,因而具有广阔的发展前景。
【Abstract】 Scalable Vector Graphics (SVG) is a W3C-recommended standard for Web graphics.It is a language for describing two-dimensional vector Graphics in XML. SVG-based images can dramatically improve graphics on the Web. It has the merits of both vector Graphics and XML. SVG graphics compact size and can scale nicely to arbitrary resolutions.Since SVG is XML-based, it is independent of platform and it is expansibility. A new XML technology, called Scalable Vector Graphics (SVG) is becoming industry standard in vector graphics. It brings the fast and high-resolution vector graphics that we currently enjoy in the print world to the Web. SVG overcomes the shortcomings of existing pixel-based Web graphics and integrate seamlessly with traditional Web standards complement with dynamic and interactive capabilities to forge the future of Web graphics.The design and implementation of Web-based cross-platform Hydropower station system is introduced in this thesis.The thesis expounds particularly the SVG, and such key technology as Web Server development technology and serval web applied software architectures are analyzed and compared.The three-tier structure based on SVG is then selected and the source code of each function model is developed.Finally, the running environment of this system is disposed and expounds particularly the key technology of this implementation.This system has many kinds of advantages and can solve the practical problem commendably.Because the solution adopts standard technology of W3C and JSP, and can be applied to various kinds of relevant operation system platform and demands, it has wide development prospects.
