img.save(saveas)
editorstring='""%s" "%s"'% (ImageEditorPath,saveas) 
os.system(editorstring)

回答1:

you can try to use time.sleep(seconds) to let your program delay for a while.

taking a screenshot with selenium webdriver bindings for python:

#!/usr/bin/env python
from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenshot.png')
browser.quit()
