摘要
在作者绣花ＣＡＤ项目中，要对点阵图形进行小角度的旋转操作。针对传统的象素线性插值法的时间和运算量太大的缺点，该文根据本系统的具体特征提出了一个快速算法可以大大降低系统计算的复杂度和计算时间。
In the project Embroidering CAD' programmed by our laboratory, we have to do some small-angle rotation operation on lattice graphics. According to the property of the system, this paper advance a fast algorithm which can reduce the complexity and save the time of the system calculation greatly, so as to eliminate the disadvantage that the traditional Pixel Linear Interpolate Algorithm spend too much time and calculation.
