基于Tkinter利用python实现颜色空间转换程序

主要基于colorsys实现，例子是从hls转换到rgb，假设要换颜色空间非常easy仅仅须要改动一个函数

用到了Scale和Canvas组件

代码例如以下：

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()

执行效果例如以下图：
