由于图像是复合的(每一位面分别表现并且图像是合成的)，因此我们可以除以每一位面，这样增加的最大值将小于255。
Since the image is a composite (i. e. each plane is represented separately and the images are combined), we can divide each of the planes, so that the maximum value of the additions is less than 255.
这样就允许我们通过使用集合操作来从匿名类或具有值约束的类来创建复合类。
This allows the use of set operations to build up complex classes from anonymous classes or classes with value restrictions.
