Taking full page screenshot with a Chrome extension

Question

Is there away to capture a screenshot of the full page, including what is below the fold, in a Chrome Extension?

The captureVisibleTab seems to be limited to what is

On Macs, while not a Chrome extension, you can use the following AppleScript to automate the process found here:

https://zapier.com/blog/full-page-screenshots-in-chrome/

tell application "Google Chrome" to activate
  tell application "System Events"
  keystroke "i" using {option down, command down}
  delay 0.3
  keystroke "p" using {shift down, command down}
  delay 0.3
  keystroke "Full"
  delay 0.5
  key code 76
end tell

Open ScriptEditor and paste that script in. Save it as a file wherever you need it locally. When you run it by pressing play in ScriptEditor, it will automatically save a full screenshot of the active tab to your Downloads folder.
