[iText-questions] FDFs and magic numbers

[Perez Carmona, David]

Hi all,

 

I expose my needs:

 

I create an XFDF file in order to fill in an AcroForm (a PDF that contains a form).

Here is an excerpt of such a file

 

<xfdf>
<f href=""/'>http://sgc00112:20620/formulario-hacienda.pdf"/>
<ids modified="A2E29BF6ADD8D44F94310FC0BA724266" original="80326FA4D068AE1326F44DF5FF152FA1"/>
 <fields>

     .....

 </fields>

</xdfd>

 

 

I've discovered that the two magic numbers modified and original, are inside the PDF (I can see them with any text/binary editor near the end of the file), but I don't know how to get them from a PdfReader

 

Please can someone give me some orientation?

 

Thanks in advance.

 

David
