Parameters

Besides url:

Code

delay   = 0,     # wait this long before shots (setTimeout param)
force   = False, # overwrite if shot exists
format  = 'png', # or jpeg
height  = 900,   # height or chrome window when fetching the URL
into    = 'img', # directory to put the screenshot into, relative to page
port    = 9922,  # port of chrome remote interface
width   = 1440,  # width of chrome window

Can run on CI/CD

The headless mode of the browser makes it possible to have the screenshooter be running on CI/CD as well, i.e. without a graphical environment. Then you may git ignore the img/http* images or set the force flag.
