AutoIt - How to read pdf document properties - pdf

Question

I'm trying to read PDF' page size eg.height X weight. Page size can be found in
File -> Properties -> Page Size
I used the code below to fetch the property value:
$path = FileOpenDialog("Select a file to read attributes",#ScriptDir,"All (*.*)")
$prop = _GetExtProperty($path,-1)
_ArrayDisplay($prop,"Property Array")
Func _GetExtProperty($sPath, $iProp)
Local $iExist, $sFile, $sDir, $oShellApp, $oDir, $oFile, $aProperty, $sProperty
$iExist = FileExists($sPath)
If $iExist = 0 Then
SetError(1)
Return 0
Else
$sFile = StringTrimLeft($sPath, StringInStr($sPath, "\", 0, -1))
$sDir = StringTrimRight($sPath, (StringLen($sPath) - StringInStr($sPath, "\", 0, -1)))
$oShellApp = ObjCreate ("shell.application")
$oDir = $oShellApp.NameSpace ($sDir)
$oFile = $oDir.Parsename ($sFile)
If $iProp = -1 Then
Local $aProperty[35]
For $i = 0 To 34
$aProperty[$i] = $oDir.GetDetailsOf ($oFile, $i)
Next
Return $aProperty
Else
$sProperty = $oDir.GetDetailsOf ($oFile, $iProp)
If $sProperty = "" Then
Return 0
Else
Return $sProperty
EndIf
EndIf
EndIf
EndFunc ;==>_GetExtProperty
By using above code i managed to get file size in MB, Created date , Modified date, Location and so on, but not Page Size. Appreciated, if anyone could advice how I can get page size. Any reference, advice or sample code is highly appreciated.

Nearly the same, but maybe it helps.
