| 摘 要： | 分析了连续位图图像几何交换的理论基础，并在此基础上时地图拼幅，点阵字符的无级处理等方面做了一些尝试。所提出的仿射变换方法，较好地满足了连续图像几何交换的精度，保持了拓扑不变性，并保证了无级交换时时原图的高度仿真。此外，还给出了利用此方法进行实验的部分结果。

| Abstract: | This article analyses the theory of continuous bitmap image's geometrical transformation,and makes attempts in cartographic jointure, dot character's stepless transformation on the basis of it. Affinity presented in the article achieves the continuous image's geometrical transformation with required precision, keeps topology constentness, and assures high emulation at stepless transformation.MOreover, it gives some practical results by using this method. |
