把算术运算和几何运算紧密结合起来，形成新颖的平面图形表达方法。
It makes a close combination of arithmetic and geometric operations, forming a new way of expression of plane figures.
这个概念是通过几何运算的操作来实现的，两个元素的旋转，就像是两个积木体一样容易堆放和处理。
This conceptual setup is materialized by a geometrical operation, the rotation of two elements, as if it were two construction toy blocks that are stacked and handled easily.
几何运算要求对图像进行灰度值插值，双线性算法可产生令人满意的效果，但是程序较复杂，运行时间较长。
Interpolation on gray images is needed in the course of geometric operation. Bilinear interpolation algorithm is effective, but its program is complex and the running time is longer.
