GPSWP:城市供水管网图形处理系统

GPSWP-The Graphic Process System of Water Supply Pipe Network for City

本文设计了一个城市供水管网图形处理系统——GPSWP,着重论述了系统结构的建立和实现方法。在IBM-PC机上初步实现了城市街道图、供水管网图的输入与输出以及图形库的管理等主要功能,具有半自动的尺寸标注与矢量汉字标注功能。针对图纸的拼接问题,提出了延伸式拼接算法,并在系统上予以实现。

A disposal system-GPSWP has been designed in this paper, which isused to design water supply pipe network for city. The establishment of systematic structure and its way of realization have been mainly expounded here. The major functions initially completed on computer IBM-AT include the input and output of urban-street drawing and water-supply pipe net drawing and the management of graphic base. It also has the function of semi-automatic measurement mark and vec tor Chinese character mark. To solve the problem of graph-combination, the exte nding combination algorithm has also been put forward and realized based on the system.
