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 |

| Thanks Ingo! I will surely try this. Also is it recommended to use the 5.22 library? |

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 |

Thanks, I have HasPageBox is fine. About the other issue with corrupt pdf file. I get the below error: there was an error processing a page. There was a problem reading this document (110) And LoadFromFile returns 1. |

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 |

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.
http://www.recoverypdf.com - pdf recovery has features allowing to
solve out problems with corrupted or lost pdf documents.
