I would like to build an AppleScript Application that when run will do the following:

  1. Open up Safari and navigate to a specific URL, or a line delimited file, or CSV. This is not required but would make generating multiple screenshots of different pages a lot quicker.

  2. Resize the Safari window to one of a number of sizes

  3. Take a screenshot of the Safari window with the filename being the url along with the screen size

I only got a partial solution, which works apart from a few small issues.

First of all, you can not store the URL in the filename (due to slashes and special characters) so you'd need to specify the Website name.

But more importantly, so far the CSV import is not implemented. Is CSV really a hard requirement, or could you get the list of URLs in a different format? If not, please update your question with exemplary lines of your CSV file. I'll work on it and update my answer as soon as possible.

on open_url(theUrl, theUrlName, x0, y0, xSize, ySize)
    tell application "Safari"
        open location theUrl
        activate

        set bounds of window 1 to {x0, y0, xSize, ySize}
        set windowID to id of window 1
        set the_state to missing value

        repeat until the_state is "complete"
            set the_state to (do JavaScript "document.readyState" in document 1)
            delay 0.3
        end repeat

        set theFolder to POSIX path of (path to desktop as string)
        set shellCommand to "/usr/sbin/screencapture -l " & windowID & " " & quoted form of (theFolder & "Screen Shot " & theUrlName & " " & xSize & "x" & ySize & ".png")
        do shell script shellCommand

    end tell
end open_url


set resolutionList to {{640, 480}, {1024, 768}}
set siteList to {{"http://www.apple.com", "Apple"}, {"http://www.google.com", "Google"}}

repeat with resolution in resolutionList
    set xSize to item 1 of resolution
    set ySize to item 2 of resolution
    repeat with theSite in siteList
        set theUrl to item 1 of theSite
        set theUrlName to item 2 of theSite
        open_url(theUrl, theUrlName, 0, 0, xSize, ySize)
    end repeat
end repeat

  • that is perfect thank you. Just one minor thing, the screenshots are taken too quickly before the page is loaded. I have increased the delay. Also, is there a way to tell Safari to Mimick it so that it thinks it is an iPhone or iPad? – Mike Feb 11 '15 at 14:23
  • Yeah, the delay part is tricky. I've tried to reside to JavaScript's readystate, but this is many times finished before the browser rendered the page completely. To change the User-Agent, you could try the AppleScript posted here (Note: I didn't test it): – Asmus Feb 11 '15 at 15:18

It's better to check if the page has finished loading before doing a screenshot. Taking Asmus' original partial answer code something along the lines of...

delay 10

tell application "Safari"
    do JavaScript "document.readyState == 'complete'" in window 1's current tab
end tell
set loaded to result
if loaded is true then
    set shellCommand to "/usr/sbin/screencapture -l " & windowID & " " & quoted form of (theFolder & "Screen Shot " & theUrlName & " " & xSize & "x" & ySize & ".png")
    do shell script shellCommand
end if

...will take charge of it.
