| Abstract: | The concinnity and efficiency of electronic map visualization are all along the aim of designers and users.Nowadays GDI is adapted to painting figures in the most of electronic map developing.But it has restricted the visualization of electronic map on account of its localization.As the upgrade edition of GDI, GDI is more powerful than GDI in many aspects.Based on the characteristics of GDI , the paper introduces the application of GDI in electronic map visualization in detail.Through practicing, it is proved that GDI has many merits in advancing of painting efficiency, improving of displaying effect and displaying transmutative textp. |
