PixWin is a fast Python API for retrieving RGB values of a pixel on Windows. It uses Python C extensions and ctypes to access GetPixel() within the Win32 API.
pip install git+https://github.com/winstxnhdw/PixWinfrom pixwin import PixWin
def loop(pixwin: PixWin):
while True:
print(pixwin.get_pixel(420, 69)) # e.g. (42, 21, 13)
print(pixwin.get_red_value(420, 69)) # e.g. 42
print(pixwin.get_blue_value(420, 69)) # e.g. 21
print(pixwin.get_green_value(420, 69)) # e.g. 13

main()Similar to PixWin, PyScreeze retrieves pixel values via the Win32 API. PixWin is ~15000x faster than PyScreeze.
