摘　　要：SVG是W3C组织制定的一套基于XML的可扩展矢量图形语言描述规范,可以用来描述矢量图形、图像、文本等图形对象。为了在Web上显示图形并对图元进行操作,提出了一个支持SVG的矢量图形编辑系统的数据模型。该模型采用面向对象的方法来描述,主要包括类结构、图元描述模型和SVG解析模型。实践证明,根据这个模型能够设计出高效率的独立于具体应用的图形编辑系统,为生成SVG图形文件提供一个可视化环境。SVG (scalable vector graphics) is an XML-based scalable vector graphics specification developed by W3C. SVG can describe such several objects such as vector graphics, images, texts, and the like. In order to display graphics on web and operate graphic elements, a data description model of vector graphics editing system based on SVG is put forward. The model described by object-oriented methods mainly includes class structures, graphic elements description and SVG parsing. The editor based on the data description model is independent of practical application systems and can provide a visual environment for creating SVG files efficiently and conveniently.
