Help required for Updating pdf Document



Hi,

        We are facing problem while Updating existing PDF document.
Actually requirement is  => we are having one PDF file, which gets updated frequently, and on each update we are appending (image or text) at the end of file.

        As per the IText API I think it is not directly possible to update existing pdf document so I have created new pdf document and copied the original pdf content to the new document and then added the new content. It's working fine but problem with this method is every time it is adding new content on new pdf page instant of continuing from the blank space in previous page.

I have attached the source Code (ModifyExistingPDF.java) and corresponding PDF files.
Input.pdf    => This is Taken as original document to which we want to append same content.
Output.pdf  => This is generated output file (Problem the new content doesn’t start from second page it is appended from next new page i.e. third page)
Any suggestion in the method, which I have adopted, or any other way to achieve the expected result is welcomed.

   

Thanks & Regards,
Sandeep
