如何将颜色RBG转为10进制

如何将 颜色RBG转为10进制

这是一个颜色生成器flash，拿出来跟大家分享一下
下面是这段代码：
var _loc4 = 7;
//每个色块间的间隔
inc = 51;
//以下这三个初始数据（inc，inc2,inc3)也许和颜色的RPG之有关，但详细的不清楚，哪位大侠可以解释下吗
inc2 = 13056;
//
inc3 = 3342336;
//
i = 0;
this.createEmptyMovieClip("container", this.getNextHighestDepth());
while (i<216)
{
       bb = i%6;
       gg = int(i/6)%6;
       rr = int(i/36);
       trace("bb="+bb+" gg="+gg+" rr="+rr);
       var _loc3 = container.attachMovie("colorOrigin", "comc"+i, i);
       newc = new Color(_loc3);
       c = rr*inc3+gg*inc2+bb*inc;//
       trace("c="+c);
       newc.setRGB(c);
       xinc = int(i%108/6);
       yinc = int(i/108)*6+i%6;
       trace("xinc="+xinc+" yinc="+yinc);
       _loc3._y = 15+xinc*_loc4;
       _loc3._x = yinc*_loc4;
       trace("_loc3._y="+_loc3._y+" _loc3._x="+_loc3._x);
       ++i;
}
