使用ctypes模块实现提取当前屏幕某一坐标RGB

from ctypes import *  # 获取屏幕上某个坐标的颜色
import time
 
def getRgb(x, y):
    gdi32 = windll.gdi32
    user32 = windll.user32
    hdc = user32.GetDC(None)  # 获取颜色值
    pixel = gdi32.GetPixel(hdc, x, y)  # 提取RGB值
    r = pixel & 0x0000ff
    g = (pixel & 0x00ff00) >> 8
    b = pixel >> 16
    rgb = [r, g, b]
    return rgb
 
 
start = time.time()
print(getRgb(x=2, y=3))  # 写xy坐标，他将提取这一像素点的RGB，以列表形式返回
end = time.time()
t = end - start   # 计算调用一次的时间
print(t)

-End-
