 Topic: Repairing PDF filesPosted: 02 Jul 12 at 1:50PM |

We are receiving PDF files from external vendors, which are being processed and transferred to an archiving solution. A small percentage of these files are corrupted, and I would like to repair them before transferring them to the archive.
I have tried to process the files using LoadFromFile followed by SaveToFile, and then tested for the returncode from SaveToFile.
It seems that this handles some of the problems, but I would like to hear if there are better ways to repair the files.
I was thinking whether I should use "RenderToFile", but the PDF format is not supported !!

Comment:
LoadFromFile() returns 1 on these files.

Hi!
Result 1 means okay. If the RenderToFile-functionalty is okay for you you should use it. What does "format is not supported" mean? You can render the pages to images and resample them later to a new pdf. If it's not necessary to have any form fields on the pdf available this could be a (slow) solution. I think the bigger poblem is to determine the corrupt pdf? Cheers and welcome here, Ingo Edited by Ingo - 02 Jul 12 at 2:51PM |

You should send some of the corrupted files to us and we may be able to add some extra processing code to handle the corrupted PDF's.
If you create a support ticket you will then be able to send us a few sample files. http://www.quickpdflibrary.com/support/support-query.php
Unfortunately corrupted PDF's are more common than they should be which make everyone's life difficult. |

I am trying to set the Field Values of the following PDF using Debenu.
But it always Crashes. My code works fine for other PDFs. I am using the Android Version of the Quick Pdf Library. However if I open the PDF in Acrobat Reader before using it with the function, it asks me if I would like save the changes(Even though I make no changes). If I click yes, the pdf size is reduces and it stops crashing.

Ludwig. You've already made a post regarding this issue.
Additionally it's not good to post a new prob at the end of a thread from 2012 :( |
