# This script gathers all the pages of a manual and merges them into a PDF.
# You'll need to play a bit with inspect-element in order to figure out the format the correct url,
# but it should be easy to adapt it to any manual.
# This script is specifically for https://www.manua.ls/audi/q3-2018/manual.
# Their url format is https://www.manua.ls/viewer/{manual-id}/{page-number}/bg{page-number-hex}.png

thanks, ill mess with that

this is great. i made two changes:

viewer_div = driver.find_element(By.CLASS_NAME, "viewer-page")
doing it this way removes the viewer UI (the arrows still show. i know selenium can hide elements, but this is good enough for what i need)
and
options.add_argument("--headless")
the other headless method works for chrome but not FF.
