摘要
提出了一种基于SVG文件格式的图元对象描述模型 ,该模型采用面向对象的方法描述图元的几何形状、应用属性以及与外界的交互功能 ,利用图元属性的继承与重载等机制减小描述图元信息的数据量 .给出了该模型在电力系统中应用的一个具体实例 ,实践表明该模型能够有效地减轻网络传输的负担、减少用户界面的响应时间 .
The disadvantages of some common graphic element description methods are analyzed and a graphic element object description model based on SVG is presented. Object-oriented methods are used in the model to define the grometric shapes, properties, events of graphic element, the inheritance and everloading of the properties are used to minimize the quantity of description. Finally, an example is given of an application using this model in an electric power system. It is proved that the network overload could be decreased and the response time of user interface could be reduced effectively in the model.
