"Do you want to save changes" always poping when closing home made PDF

Jun 19, 2012 1:08 AM

Hi,

 

I create a pdf by myself in one of my application (only external lib used is zlib for deflate streams)

I tried to follow the PDF references.

 

It's a simple PDF file with a few pages, some text & lines to underline (deflated or not same problem), and 3 fonts, a xref.

 

The PDF is showing perfectly in the Reader X 10.1.1 but when i try to close the window it always asks me :

"Do you want to save changes before closing".

 

All save options are disabled in the preferences of the reader.

 

Is there anything to do in the reader to avoid this ?

Is there anything to do in the PDF itself to avoid this ?

Or maybe the PDF is not completly correct ? Which is possible even if i tried to follow the specs in the official reference document, there are alot of chances that i may have done something wrong.

    Yes. Adobe Reader corrects the errors and you get the prompt when you close the document.

    I first tried the version without the deflated stream (so everything uncompressed) against the online repair tool to check/analyse it @ https://www.pdf-tools.com/osa/repair.aspx

    And it says no error found, but the reader still want to save it when closing so i still had no clue at this point.

     

    Fortunately, i finally found what was wrong with my generated PDF.

     

    In my xref table, each object reference was not end by a full EOL, i only did put a newline char.

    Now i have "carriage return" "newline" which is the full EOL and the reader is happy and close the file silently.

    As suspected i did not follow correctly the specs on xref table

     

    Now i'll go and figure what i did wrong with the deflate filter

     

    Thanks for your help.
