计算机图形学的课程设计，边界填充和种子扫描算法-computer graphics curriculum design, and filled with seeds border scanning algorithm

种子填充算法,先把种子像素如栈,再逐点扫描该点左右边界之间的像素,并置成新的像素,即完成一条扫描线的转换,然后再取上下扫描线并重复上面的过程,即完成填充.-seed filling algorithm, the first seed pixels as stack, then scan the point-by-point about the border between the pixels, home and a new image, namely, the completion of a
