Hi everyone, I'm trying to use Automator to batch process PDF files. I have hundreds of academic journal article PDFs whose page sizes vary from 5x7 inches to A4 format (8.27 x 11.69 inches). I want to scale all the PDFs to US Letter size (8.5 x 11.0 inches) such that smaller originals remain 100% scale but are centered on the larger page and larger originals are scaled down to fit the page. Manually opening a PDF in Preview.app, scaling it to US Letter paper, and using the Save as PDF option is producing the desired output for me. I captured my workflow using the Watch Me Do action in Automator, then adjusted it into the following AppleScript. -- a Get Specified Finder Items action to specify the input PDFs precedes this script on run {input, parameters} repeat with filePath in input -- Open the file in Preview tell application "Preview" open filePath activate end tell -- Give Preview some time to open the file delay 2.0 -- Press ⌘P set timeoutSeconds to 0.25 set uiScript to "keystroke \"p\" using command down" my doWithTimeout(uiScript, timeoutSeconds) -- Click the “Scale to Fit:” radio button. delay 2.0 set timeoutSeconds to 2.0 set uiScript to "click radio button \"Scale to Fit:\" of radio group 1 of group 1 of group 2 of scroll area 2 of splitter group 1 of sheet 1 of window 1 of application process \"Preview\"" my doWithTimeout(uiScript, timeoutSeconds) -- Click the “<fill in title>” menu button. delay 4.0 set timeoutSeconds to 2.000000 set uiScript to "click menu button 1 of group 2 of splitter group 1 of sheet 1 of window 1 of application process \"Preview\"" my doWithTimeout( uiScript, timeoutSeconds ) -- Save as PDF… delay 2.0 set timeoutSeconds to 2.0 set uiScript to "click menu item 2 of menu 1 of splitter group 1 of sheet 1 of window 1 of application process \"Preview\"" my doWithTimeout(uiScript, timeoutSeconds) -- Click the “Save” button. delay 8.0 set timeoutSeconds to 2.0 set uiScript to "click UI Element \"Save\" of sheet 1 of sheet 1 of window 1 of application process \"Preview\"" my doWithTimeout(uiScript, timeoutSeconds) -- Press ⌘W to close the file delay 0.25 set timeoutSeconds to 2.0 set uiScript to "keystroke \"w\" using command down" my doWithTimeout(uiScript, timeoutSeconds) end repeat return input end run on doWithTimeout(uiScript, timeoutSeconds) set endDate to (current date) + timeoutSeconds repeat try run script "tell application \"System Events\" " & uiScript & " end tell" exit repeat on error errorMessage if ((current date) > endDate) then error "Can not " & uiScript end if end try end repeat end doWithTimeout My problem arises at the Save as PDF step. When this action runs, I see the PDF menu pop open: but the Save as PDF... menu item doesn't get clicked. Instead, I get an error: Can anyone advise on how to overcome this error?
