摘　　要：提出一种外轮廓等距线填充扫描的生成算法。讨论了填充扫描线生成的关键技术,包括偏移矢量的计算方法、无效环的剔除方法、多边形之间的布尔运算以及外轮廓等距填充扫描线生成算法。提出的方法不仅简单,且易于编程实现。应用表明,算法十分稳定可靠。A scanning algorithm of outer contour＇s equidistant line was presented, and the key technologies of scanning line were discussed in detail. These technologies include computing method of offsetting vector and eliminating method of invalid loop, Boolean operation of between polygons and scanning algorithm of outer contours equidistant line. The proposed algorithm is simple and easy to program and applications show the algorithm is steady and reliable.
