hello, I'm new in the list but we've been using iTextSharp for a while. I developed a windows service that batch sign with Timestamp lots of PDFs (hot folder like). Since last week, all OK. Now I'm experiencing problems runing the service in Windows 2008 x64.
Here is the process: 1 - User can opt to add an image to the footer and determine where to put the Signature Appearance. 2 - when the PDF is copyed to Input Folder, an Event (FileSystemWatcher) put that file at Queue. 3 - One available thread of the service open that PDF, insert the Image and SAP 4 - the service then sign and put the timestamp at the signature. 5 - the service saves that new PDF signed at output folder. The Problem: We are using windows 2008 x64 to get higher performance. The service runs OK on this system. This week we realized that once we copy signed pdfs to any desktop (via ciffs or RDP) it get corrupted and the signature is marked as invalid. More info: Searching the web and debuging everything we noted this 1 - When i sign at desktop and copy to server, the file opens at the server. If i copy that file back to desktop, it get corrupted. 2 - When i sign at server, it opens ok at server. If i copy to desktop it get corrupted. 3 - Looking inside de corrupted PDF we can see bytes after the original %%EOF. It seems to be some parts of the original file replicated at the end... 4 - One file signed with the same routine don't get corrupted at transfer. I could not realise why... Follows links to example PDF: The pdf signed - http://www.imprensaoficial.com.br/itext/signed.pdf The PDF corrupted after transfer - http://www.imprensaoficial.com.br/itext/corrupted.pdf The original one - http://www.imprensaoficial.com.br/itext/original.pdf It would be great if someone can give a hit about the cause, i don't know where to look anymore. thanks a lot. -- Lucas Matis --------------- "O segredo da genialidade é carregar o espírito da infância na maturidade."
