How to validate PDF?

[Iczer]

Is there  reliable way to validate pdf file beside do it by manually opening it in some reader and inspecting it by eyes?

I tried to use popler dll, but in most cases it open even crippled files...

Have you tried using File Signature for PDF ?

I am not sure if this method is 100% reliable, but I would verify it as follows:

; The initial 8 bytes of a PDF-File usually indicates its version :
; %PDF-1.X or %PDF-2.X (where X is a number)
; Valid version indicators :
; %PDF-1.0, %PDF-1.1, %PDF-1.2, %PDF-1.3, %PDF-1.4, %PDF-1.5, %PDF-1.6, %PDF-1.7 and %PDF-1.8 , meanwhile also %PDF-2.x
#include <WinAPIFiles.au3>
Local $sFilePath = @ScriptDir & '\Test.pdf'
Local $sFileRead
Local $hFileOpen = FileOpen($sFilePath, BitOR($FO_READ, $FO_BINARY))
If $hFileOpen = -1 Then
    MsgBox(0, "", "An error occurred when reading the file.")
    Exit
EndIf

$sFileRead = FileRead($hFileOpen, 8)
If StringRegExp(BinaryToString($sFileRead),'(?i)^\%PDF-\d\.\d') Then
    MsgBox(0, "", "PDF-File detected")
Else
    MsgBox(0, "", "No PDF-File detected")
EndIf
FileClose($hFileOpen)

What you mean... validate .

If you need to validate exact layout for something like mailers, then not that I know of.

 

If you just need to validate some specific text was included in the PDF, then yes there are some apps I've used in the past that will pull out the text that you can then verify with AutoIt code.
