python实现颜色空间转换程序(Tkinter)

from Tkinter import * 
import colorsys 
#操作后的响应函数 
def update(* args): 
  'color' 
  r,g,b = colorsys.hls_to_rgb(h.get() / 255.0, l.get() / 255.0, s.get() / 255.0) 
  r,g,b = r * 255, g * 255, b * 255 
  rgb.configure(text = 'RGB:(%d, %d, %d)' % (r, g, b)) 
  c.configure(bg = '#%02X%02X%02X' %(r, g, b)) 
 
root = Tk() 
hue = Label(root, text = 'Hue') 
hue.grid(row = 0, column = 0) 
 
light = Label(root, text = 'Lightness') 
light.grid(row = 0, column = 1) 
 
sat = Label(root, text = 'Saturation') 
sat.grid(row = 0, column = 2) 
#初始化颜色为rgb的000，也就是纯黑色 
rgb = Label(root, text = 'RGB(0, 0, 0)') 
rgb.grid(row = 0, column = 3) 
 
 
h = Scale(root, from_ = 255, to = 0, command = update) 
h.grid(row = 1, column = 0) 
 
l = Scale(root, from_ = 255, to = 0, command = update) 
l.grid(row = 1, column = 1) 
 
s = Scale(root, from_ = 255, to = 0, command = update) 
s.grid(row = 1, column = 2) 
 
c = Canvas(root, width = 100, height = 100, bg = 'Black') 
c.grid(row = 1, column = 3) 
 
root.mainloop()
