| 摘 要： | GDI+是Windows中的图形接口,本文通过利用GDI+中的圆弧方法、路径填充以及变换矩阵对象等方法设计了多种全曲轴量化图形组合形式的生成算法,实现了地学信息数据快速生成全曲轴量化统计图形的功能.这样的全曲轴图形形式活泼多样、表现力强,是有效表达复杂地学信息的一种可视化方法.

| Abstract: | GDI+,the graphic interface of Windows,provides some actions such as DrawArc,FillPath and Matrix Translate,which can hel Pus drawing geographic quantitative graphs of full curving axis coordinate system.In the paper,these arcs' shape was easy controlled,and the grid of full curving axis coordinate system and filled bars were a chieved easily.At the same time,it designed algorithm to draw combined forms of full curving axis coordinate system quantitative graphs,which could make data of geo-information into quantitative graphs of full curving axis coordinate system immediately. |
