示例1: julia
int Computation::julia(int xpt , int ypt , double xmin , double xmax , double ymin , double ymax , float conx , float cony)
{
MetaData m;
int color;
int h;
double minx = xmin;
double maxx = xmax;
double miny = ymin;
double maxy = ymax;
double pixCorx = (maxx - minx) / m.getWidth();
double pixCory = (maxy - miny) / m.getHeight();
long double x = xpt * pixCorx + minx;
long double y = maxy - ypt * pixCory; //converting from pixels to points
long double xnew = 0;
long double ynew= 0;
for(h = 1 ; h <= iterations + 1; h++)
