Other than Selenium, this example also requires the PIL Imaging library. Sometimes this is put in as one of the standard libraries and sometimes it's not, but if you don't have it you can install it with pip install Pillow
from selenium import webdriver
from PIL import Image
from io import BytesIO
fox = webdriver.Firefox()
fox.get('http://stackoverflow.com/')
# now that we have the preliminary stuff out of the way time to get that image :D
element = fox.find_element_by_id('hlogo') # find part of the page you want image of
location = element.location
size = element.size
png = fox.get_screenshot_as_png() # saves screenshot of entire page
fox.quit()
im = Image.open(BytesIO(png)) # uses PIL library to open image in memory
left = location['x']
top = location['y']
right = location['x'] + size['width']
bottom = location['y'] + size['height']
im = im.crop((left, top, right, bottom)) # defines crop points
im.save('screenshot.png') # saves new cropped image
and finally the output is... the Stackoverflow logo!!!
Now of course this would be overkill for just grabbing a static image but if your want to grab something that requires Javascript to get to this could be a viable solution.
