摘　　要：针对具有IFS码的分形图给出了一种通用的绘图方法,以绘任意具有IFS码的分形图为目标,实现了分形图与绘图区域的映射关系。首先定义分形图绘图区域,其次计算分形图横向和纵向距离的最大值,接着计算分形图在绘图区域的伸缩比例因子,最后将分形图上的点映射到绘图区域而实现绘图。本方法的关键技术是建立了分形图上的点与绘图区域上的点之间的映射关系。测试表明,该方法能绘任意具有IFS码的分形图,为分形图的绘制提供了一种通用方法。This paper presents a general drawing method for fractal graphs that can be iterated with IFS.This method draws any fractal graph with IFS code and realizes the mapping relationship between fractal graph and drawing region.First,the drawing area of the fractal graph is defined.Secondly,the maximum transverse and longitudinal distances of the fractal graph are calculated.Then,the scaling factor of the fractal graph in the drawing area is calculated.Finally,the points on the fractal graph are mapped to the drawing region to realize drawing.The key technique of this method is to establish the mapping relationship between the points on the fractal graph and the points on the drawing area.Tests show that this method can draw any fractal graph with IFS code.The design of this method provides a general method for drawing fractal graphs.
