A single ant cannot do much on its own, but the colony as a whole solves complex problems such as building a sophisticated nest, maintaining it and filling it with food.
Compared with the normal algorithms, the new one is efficient in algorithm, simple in realization for scan filling of simple connected area and also applicable to the filling of the complex area.
对比传统单连通区域扫描线填充法，新方法算法效率高，实现简单，对复杂区域的填充同样适用。
