基于图案填充的直、斜格网绘制及图廓的自动生成

在分析我国矿图普遍采用自由分幅的优点与难点的基础上,提出了一种基于图案填充的直、斜格同绘制与图廓自动生成的新算法,该方法既考虑到格网方向,也解决了注记位置、方向、均匀性、合理性等的计算机自动识别问题,并且可针对不同比例尺图形,绘出相应格网和自动进行图廓注记。

The Algorithm Researching of the Drawing of Inclined & Square Net by Patter Hatching and the Automatic Forming of Map-Outline

On the base of analyzing the advantage and weakness of using freely dividing map area in China,this paper provides a easy & efficiency patter hatching method in drawing net.and at the same time.the map-outline is automatically forming. It not only considers of the net direction,but also solves the problem of computer automatically recognzing the label position.direction,interval and reasonableness.The algorithm is also suitable for different scales.
