The problem don't come with this %%EOF. This is a linearized pdf. A pdf can contain more than one %%EOF in 2 cases : linearisation and incremental save. The real problem come with startxref 0. That QuickPdf can not handle at the momment.

Zarko, Delbeke, and Ingo (plus readers),

We're working on providing a solution for this problem to include in an upcoming version (7.13) of Quick PDF Library.

Today, the production version of 7.12 will be released.

And thanks all.

Cheers, -Karl

Delbeke,
 
I am aware of the function result value ... my question was initially related to "why" does it fail to load - since AReader can open it.
 
The answer was provided by Ingo.

Hi zarko
 
In fact it does indicate you that the file can' be laoded.
Here is a sample writen in vb6
 
    On Error Resume Next
    lRet = m_oDoc.LoadFromFile(Value)
    On Error GoTo 0
    If lRet = 0 Then
        MsgBox "File can not be opened", vbCritical
        Exit Sub
    End If

Ingo,
 
Thanks for the info.
 
I do not have any idea what this EOF is doing there :(
 
p.s.
Need to process a bunch of PDFs in my application and this file failed to load.
 
What is important here is that this file IS corrupted - the fact that AdobeReader can read it .. who cares .. for me it would be enough to report as "cannot open file".

Hi Zarko!

I've looked inside with PSPad (you can use any other editor as well).
The first content you can see below.
I've deleted the string "%%EOF", made a new save and then QuickPDF had no problem to read/load the file! It's a distiller document initially created with Word. Where this E(nd)O(f)F(ile) comes from... i don't know? A real accident ;-)
A 100 mb adobe reader installation can handle this - for the 2 mb of QuickPDF it's not so easy i fear.

Cheers, Ingo

Of course, these would be kind ;)
 
But not easy to implement I think. A easyer way should be a return value more significant, actualy 0, all is correct and 1, load has fail.

Hi,
 
How about some kind of descriptive (error) message to why the LoadFromFile has failed?

Hi Zarko
 
The most frenquetly corrupted pdf are corrupted in the cross reférence (generaly at the end of the file). When Acrobat reader find this kind of corruption, he corrects the problem with a complete reconstruction of cross reference.
 
I suppose QuickPdf library will do it in a near future.
 
Cheers

Ingo,
 
Thanks for the offer.
 
I "know" that the file is corrupted .. I just am not sure why it loads with Acrobat Reader with no problems .. plus it would be great if when LoadFromFile fails .. a more descriptive error is provided.
 
p.s.
PDF sent to your email..

Yes, Zarko Gajic from delphi.about.com :)
