PdfProcessing: Handle import of documents with invalid offsets of the objects inside the cross-reference table

The current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, we may implement a mechanism for importing documents with invalid offsets for the objects inside the table.

Hi Travis,

One of the other posts mentioned saving the file with a third-party application as a workaround. That is the only possible solution at this point.

I just noticed that our developers started investigating this. I can't promise anything but hopefully, they will be able to fix it for the next service pack.

Let me know if you have additional questions.

Thank for the update. You mention a workaround, but to my knowledge, none exists. The Telerik Reporting engine creates a PDF output of the report that the Telerik PDF Processing library cannot handle. If there is a workaround, I'm all ears. But as it stands, my only option appears to be limited to finding another reporting library that can produce PDFs that can be merged together, as the ability to merge several of their PDFs into a single document is a must have for my client and is non-negotiable with them.

Hi,

I offer my sincerest apologies on behalf of the entire team for the trouble this issue has caused!
I understand workarounds that need to be applied often are time and energy-consuming. Our team is devoted to providing the best experience to our users, which includes fixing bugs and implementing features that affect the most clients. We do our best to fix all bugs, yet some receive less attention than others, which is why they can sometimes be delayed, such as this one. As much as I'd like to share an ETA on its resolution, currently, none is available, so I would not want to mislead you. Once we resolve this issue, we will immediately update the public feedback page to notify you and other clients.

Once more, please accept our apologies for this delay.

Regards,
Dimitar

I have recently run across an issue that is caused by this same underlying issue. In my case, I save the report contents to a PDF and then later, users attempt to "combine" those PDFs together into a single file using the PDF Processing library supplied by Telerik and some of the data from the original PDFs with the problem is missing in the compiled PDF.

This has recently become a necessity for our project - we have looked at alternatives like pdf2txt, which can extract the text to a readable format, but this would come at a significant cost and we are not prepared to do that unless necessary.

The PDF documents we are trying to open, all open fine in Sumatra PDF and Acrobat, and if saved from those applications, it is then readable, but this is not a workaround we will try and force our users to perform.

Hello Divya,

Thank you for your feedback. This task is not scheduled for implementation during the current release and, at this point, I cannot say when it might be available. Please, make sure to continue following this item so you can receive notifications about status changes on it.
