如何获取桌面上像素的颜色？(Linux)

from PIL import Image
import PIL.ImageOps

def get_pixel_color(x, y):
    # 获取屏幕尺寸
    screen_width, screen_height = autopy.screen.size()

    # 检查坐标是否在屏幕范围内
    if x < 0 or x > screen_width or y < 0 or y > screen_height:
        return None

    # 截取屏幕截图
    im = autopy.bitmap.capture_screen()

    # 获取像素颜色
    pixel_color = im.get_color(x, y)

    return pixel_color

# 获取桌面左上角像素的颜色
x, y = 0, 0
color = get_pixel_color(x, y)
print(f"The pixel color at ({x}, {y}) is {color}")
