Is it possible to get the color of a particular pixel on the screen with it's X and Y coordinates?
提问by rectangletangle
I would like to get the color of a particular pixel in Python using its X Y coordinates, is this possible?
我想使用 Python 的 XY 坐标获取特定像素的颜色，这可能吗？
This is in Windows, if it makes a difference.
这是在 Windows 中，如果它有所不同的话。

See http://rosettacode.org/wiki/Color_of_a_screen_pixelunder the heading for python
请参阅Python 标题下的http://rosettacode.org/wiki/Color_of_a_screen_pixel
they give:
他们给：
def get_pixel_colour(i_x, i_y):
import win32gui
i_desktop_window_id = win32gui.GetDesktopWindow()
i_desktop_window_dc = win32gui.GetWindowDC(i_desktop_window_id)
long_colour = win32gui.GetPixel(i_desktop_window_dc, i_x, i_y)
i_colour = int(long_colour)
return (i_colour & 0xff), ((i_colour >> 8) & 0xff), ((i_colour >> 16) & 0xff)
print get_pixel_colour(0, 0)
which uses Python Extensions for Windowswhich is available for python 2.3 to 3.1 at http://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/
它使用适用于 Windows 的 Python 扩展，可用于http://sourceforge.net/projects/pywin32/files/pywin32/Build%20214/ 上的python 2.3 到 3.1
