    areas = solveItemColors(image, self.layout)

    drawTextMontage(newImage, areas, cycle(self.text), self.font, self.calc_draw_color)
    return newImage

#Python #code 总的弄了一个 Montage 和 runOn，目的是复用 refershLayout 可提供的信息
runOn 的逻辑很简单，就是新建一个 mode 一样的 image，然后求颜色、作画。

calc_draw_color 也被合并到 cfg 动态对象里去了

草，原来绘制和矩阵处理天生不兼容 #CV #Python #visualize
反正我是熟悉 n m y x i j 那一套
可以把 for (i=0; i<n; i++) 套到 绘制程序里

我们只需要往 i, n 扩展一个 j, m 就可以处理项目和 y, x 不匹配的情况
然后矩阵处理又是另一种情况，没有 w,h 什么的

重写了一部分，还没起床就不折腾了…… 搞不清 bisect 和这个程序是做什么的就在乱写，差点把 find_entry() -> int（

重写的部分当然比较激进，常量是动态计算的，然后用了 k, e, ek 这些简写法(差点用成 k, for k1in...) posEqEntry 也是不常规的名字（没办法了）

不过我重写的控制流还好，把
while True:
x = xs[i]
if p1(x):
if p2(x): return v1
else: i += 1
else: break
return v2
简化了（其实只需要分析下 i in range(0,len(xs)) 就知道）
但是没有删全局变量（毕竟我不了解问题，或许可以作参数顺序/提升至class ）

补充：写错了？
