 Topic: Corrupt pdf and Crop markPosted: 08 Jan 09 at 3:49AM |

Hello,
I have two questions: #1. Identify corrupt pdf There are certain files which can not be read by the pdf file and it throws 110 error. Is there a way we can identify that the file is corrupt. In this case the file size is not 0 kb. #2. How can I identify if there are crop marks available in the PDF file, before I can process the crop mark. Please suggest |

Hi!
Your questions seems to me as if you're NOT using QuickPDF from iSED but any other pdf-library? If not: Which version of QuickPDF you are using? Cheers, Ingo |

Please try the last version 5.22 from the library section.
And see if your probs still exist. Cheers, Ingo |

Actually these are not the problems. I want to know if there are any options to check if there are pdf crop marks on a pdf before I remove them. Just to reduce the overhead of the application.
Other question is: If there is a PDF which is corrupt, how can I identify that pdf is corrupt? |

Hi!
Crop: Use the function "HasPageBox". If the returning value is "2" then it's a crop box. Corrupt: Use the function "LoadFromFile". If the returning value is "1" then the pdf could be load successfully - which means that the file is okay. Cheers, Ingo |

It's the latest version as dll - Try it.
Normally newer versions have less bugs and more functions... Please read in the library section ;-) Cheers, Ingo |

Hi!
Who raises these messages? "there was an error processing a page. There was a problem reading this document (110)" It's not QuickPDF. Why not reading the pdf page by page... getting some data from the pages... and if there's an error -> That's it. Perhaps the errors are always from the same pdf-engine (check creator and producer) the check will be much faster. Cheers, Ingo Edited by Ingo - 09 Jan 09 at 7:13AM |

Yes, the dll do not raise this error.
When I open the PDF on a pdf reader manually i get this error. however the LoadFromFile method returns 1 i.e success. |

There is
a program which is able to help in this complicated situation. It owns many
other facilities such as restoring data after power failures, virus attacks.
pdf recovery has features allowing to
solve out problems with corrupted or lost pdf documents.
