    self.font = cfg.font; self.scale = cfg.scale; self.spacing = cfg.spacing
    self.text = cfg.text
    self.key_color = cfg.key_color; self.calc_draw_color = cfg.calc_draw_color

    self.newSize = tuple(int(sz*cfg.scale) for sz in size)
    self.refreshLayout()

    if len(self.text) == 0: return
    self.layout = solveItemLayout(self.newSize, self.font.getsize(self.text[0]), self.scale, self.spacing)

  def runOn(self, image):
    areas = solveItemColors(image, self.layout)
    newImage = Image.new(image.mode, self.newSize, self.key_color)
    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
