PDFScanner Automation I recently purchased PDFScanner to convert a bunch of scans into searchable, smaller-sized PDFs. I specifically picked PDFScanner because of its AppleScript automation (see "Features" section on PDFScanner's website).



However, when I put together the above script using the built-in commands as documented in PDFScanner's AppleScript library and tried to run it, I got the following error:



At this point, I'm stuck. I've contacted the developer. He said this exact same scripts works for him and that I should try to delete and reinstall PDFScanner, which I did to no avail. Can anybody figure out what the problem is?



Here's the complete script:

on run {input, parameters}

    tell application "PDFScanner"
        deskew input
        rasterize input
        ocr input
    end tell

    return input
end run
As it turns out, the cause of the problem was trivial. I simply used the wrong type of (formatted) quotation marks in tell application "PDFScanner". After removing the formatting, everything worked like a charm. This workflow saved me quite some time:



on run {input}

    tell application "PDFScanner"
        repeat with PDF in input
            deskew PDF
            rasterize PDF
            ocr PDF to PDF
        end repeat
    end tell

    return input
end run
