除了硒以外，此示例还需要PIL映像库。有时将其作为标准库之一放入，有时却不作为，但如果没有，则可以使用
pip install Pillow
from selenium import webdriverfrom PIL import Imagefrom io import BytesIOfox = webdriver.Firefox()fox.get('http://stackoverflow.com/')# now that we have the preliminary stuff out of the way time to get that image :Delement = fox.find_element_by_id('hlogo') # find part of the page you want image oflocation = element.locationsize = element.sizepng = fox.get_screenshot_as_png() # saves screenshot of entire pagefox.quit()im = Image.open(BytesIO(png)) # uses PIL library to open image in memoryleft = location['x']top = location['y']right = location['x'] + size['width']bottom = location['y'] + size['height']im = im.crop((left, top, right, bottom)) # defines crop pointsim.save('screenshot.png') # saves new cropped image最后输出是… Stackoverflow徽标！！！
当然，现在仅获取静态图像将是过大的选择，但是如果您想要获取需要Javascript才能实现的功能，那可能是一个可行的解决方案。
