| 摘 要： | 介绍利用栈这一特殊的数据结构来计算屏幕上某一区域面积的方法．通过判断某一像素点是否在该区域中，若在则将其压栈，然后判断该像素点的相邻点是否也在该区域中，若某一像素点的相邻点均已处理过，则将其出栈，由累计压栈次数便可统计出该区域的面积．

| Abstract: | The paper mainly introduces a method to calculate the area of a certain region on a screen by stack, one of special data structure. It can be decided whether a pixel is in the region. If it is, it can be made push stack. Then it may be decided whether the consecutive point of the pixel is also in the region. If the consecutive point of certain pixel has already been processed, it can be made pop stack. The total number of the push stack can help calculate the area of the region. |
