Selenium Webdriver，屏幕截图为numpy数组(Python) [英] Selenium Webdriver, screenshot as numpy array (Python)

问题描述

是否可以使用Selenium Webdriver截屏并将其转换为numpy数组而不是保存它?我需要在openCV中使用它.

Is there a way to take a screenshot with selenium webdriver and convert in to a numpy array instead of saving it? I need to use it with openCV.

注意:我不想保存图像并再次打开它

Note: I don't want to save the image and open it again

推荐答案

我确定有一种更有效的方法，但这对我有用:

I'm sure there is a more efficient way of doing this, but this is what worked for me:

from selenium import webdriver
from PIL import Image
import StringIO
import numpy as np

browser = webdriver.Firefox()
browser.get('https://www.google.ca/?gws_rd=ssl')

data = browser.get_screenshot_as_png()

img = Image.open(StringIO.StringIO(data))

numpy_array = np.asarray(img)
