"ImageGrab.grab() 方法太慢"

Question

So i need to get a bunch of screenshots every second, like 5. I am using it to program a bot for a game. However imagegrab method takes like 0.3 seconds, which is terribly slow for me. Even after specifying the bbox values it still takes like 0.3 seconds. I think should mention that I am on a mac. Is there a better way for me

I even tried the os.system("screencapture filename.png") which has a runtime of 0.15-0.2 seconds which is nice but I want to go faster.

Answer 1

Another solution is to use Python MSS<\/a> .

from mss import mss
from PIL import Image

def capture_screenshot():
    # Capture entire screen
    with mss() as sct:
        monitor = sct.monitors[1]
        sct_img = sct.grab(monitor)
        # Convert to PIL/Pillow Image
        return Image.frombytes('RGB', sct_img.size, sct_img.bgra, 'raw', 'BGRX')

img = capture_screenshot()
img.show()

Answer 2

Question : what could preform better than ImageGrab.grab() on a Mac<\/h1>

I did a test between mss, pil, and pyscreenshot and measured the average time it took to take a various sized image grabs and reported the time in milliseconds.

Answer 3

So how I got it working for me is by using

os.system("screencapture -R0,0,100,100 filename.png")
im = Image.open("filename.png")
