Get property from pdf files

[KatoXY]

Hi,

I have huge numbers of pdf files. All of them have set property such like Author, Subject, Keywords.

Is any way to get this informations?

I mean about _WordDocPropertyGet function which works with pdf files.

[water]

There is an available to retrieve extended properties of a file.

Generally this script working with files but it doesn't read properties from pdf.

I take one from Dell page: http://support.dell.com/support/edocs/systems/op990/en/ts/ts_en.pdf

Normally it has Title and Author but script doesn' read it.

Melba23:

I don't understand this topic. Probably I couldn't use this function.

I checked in Windows 7 x64, AutoitScript 3.3.6.1

If you search for properties that aren't visible for Windows then you have to open the document and retrieve the data.

How to access this data depends on the program you have installed as PDF reader (Adobe Acrobat Reader, Foxit ...).

What do you use?

[KatoXY]

Adobe Acrobat Reader X

Ver 10.0.1.434

[water]

you can find a somehow "brute" method by reading the file and searching for the keyword. I don't know how fast this emthod is i you have a lot of documents.

[water]

Or you can try the Adobe COM interface as described

[water]

Here is an example script to retrieve title, Author, Keywords, Subject, Creator, Producer, CreationDate:

expandcollapse popup

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc")    ; Initialize a COM error handler
$sFilePath = "C:tempTest.pdf"
$oApp = ObjCreate("AcroExch.App")   ; start Adobe Acrobat
$oDoc = ObjCreate("AcroExch.AVDoc")  ; connect to Ac Viewer
If $oDoc.Open($sFilePath, "") Then   ; open the file
    $oPDDoc = $oDoc.GetPDDoc
    $sAuthor = $oPDDoc.GetInfo("Author")
    $sTitle =  $oPDDoc.GetInfo("Title")
    $sKeywords = $oPDDoc.GetInfo("Keywords")
    $sSubject = $oPDDoc.GetInfo("Subject")
    $sCreator = $oPDDoc.GetInfo("Creator")
    $sProducer = $oPDDoc.GetInfo("Producer")
    $sCreationDate = $oPDDoc.GetInfo("CreationDate")
    MsgBox(64, "PDF Info", "Author: " & $sAuthor & @CRLF & _
        "Title: " & $sTitle & @CRLF & _
        "Subject: " & $sSubject & @CRLF & _
        "Keywords: " & $sKeywords & @CRLF & _
        "Creator: " & $sCreator & @CRLF & _
        "Producer: " & $sProducer & @CRLF & _
        "CreationDate: " & $sCreationDate)
EndIf
$oApp.exit() ; close process
; release objects
$oDoc = 0
$oApp = 0
$oPDDoc = 0

; This is my custom defined error handler
Func MyErrFunc()

  Msgbox(0,"AutoItCOM Test","We intercepted a COM Error !"    & @CRLF  & @CRLF & _
             "err.description is: " & @TAB & $oMyError.description  & @CRLF & _
             "err.windescription:"   & @TAB & $oMyError.windescription & @CRLF & _
             "err.number is: "       & @TAB & hex($oMyError.number,8)  & @CRLF & _
             "err.lastdllerror is: "   & @TAB & $oMyError.lastdllerror   & @CRLF & _
             "err.scriptline is: "   & @TAB & $oMyError.scriptline   & @CRLF & _
             "err.source is: "       & @TAB & $oMyError.source       & @CRLF & _
             "err.helpfile is: "       & @TAB & $oMyError.helpfile     & @CRLF & _
             "err.helpcontext is: " & @TAB & $oMyError.helpcontext _
            )

Endfunc

A good reference for Acrobat X.

Mmmh,

the product : "Adobe Acrobat Reader X Ver 10.0.1.434" doesn't exists.

You may have; "Adobe Acrobat x ... the $$$ product or just the free "Adobe Reader X .."

I would asume you have Reader only.

With that you don't can use the ActiveX components like "$oApp = ObjCreate("AcroExch.App")", which is stated in the third post from @water.

The "brute" method, also remarked by @water, my work and is maybe good enough.

Otherwise I would take pdfTk.exe or perhabs http://www.becyhome.de/download_eng.htm#becypdfmetaedit

which also can be used as command line tool and has a batch option.

Oops

I didn't know that Adobe Acrobat was still installed on my new machine. I told our IT department to uninstall Adobe Acrobat some months ago - but they didn't do it.

So as the script was working fine I assumed the Adobe Reader had a COM interface as well.

[ReFran]

Let Adobe Acobat on the maschine.

For most quick task you still can use older versions (5-7,8,9).

For merge, split, bookmarks .. I use mostly pdftk or mbtPdsAsm.

The Reader has a small interface for use it embedded (like for IE,..), but there are only some few properties, which can be influenced (zoom, pageview, ..).

best regards, Reinhard
