思路：单调递减栈，找「上一个比当前价格大的元素索引」。正序遍历，弹出所有 ≤ 当前价格的索引；跨度 = 当前索引 - 栈顶索引（栈空则为 当前索引 + 1）。
Knowing this, we can modify the N-Convex algorithm covered earlier such that the candidate weights are given by the barycentric coordinates of the input pixel after being projected onto a triangle whose vertices are given by three surrounding colours, abandoning the IDW method altogether1. This results in a fast and exact minimisation of , with the final dither being closer in quality to that of Knoll’s Algorithm.，更多细节参见Line官方版本下载

The async iterator based approach provides a natural bridge between this alternative approach and Web streams. When coming from a ReadableStream to this new approach, simply passing the readable in as input works as expected when the ReadableStream is set up to yield bytes:，这一点在搜狗输入法下载中也有详细论述
