摘　　要：随着科学技术的进步,计算机广泛应用到各个领域和行业,二维基本图形是计算机图形学表示复杂图形的基础,利用高效率的二维图形变换方法尤为重要。基于二维图形的基本变换规则提出新方法,对基本图形的平移变换、比例变换、旋转变换等做出改进,主要论述简单二维基本图形的变换,例如三角形、矩形和圆形,尽可能统一到"基本圆"中进行处理和变换。With the progress of science and technology, computer is widely applied to various fields and industries. 2D graphics is the basis of com- puter graphics in representing complex graphics. Using efficient 2D graphics transformation method is particular important. Based on the 2D graphics transformation rules, proposes a new method to make improvement on basic graphics transformation, such as translation, scale and rotation, in which states the transformation of 2D graphics, like triangle, rectangle and circle and unified as far as possible to the ba- sic circle in processing and transformation.
