Hi,

I am getting

rebuild failed: value was either too large or too small for an int32.; original message: value was either too large or too small for an int32.

While tring to read the pdf file using

ITextSharp

Pdfreader in C# MVC.

Below is my code,

PdfReader pdfReader = new PdfReader(fileName);

Help to solve this issue. I am only getting this issue for specific documents. But I am able to load the same document in Adobe Arcobat Document.

The message is quite clear. You are trying to put a value into an int field that is too large. You need to use your debugger to find out where this occurs in your code, and correct it.

What version of iTextSharp are you using? Does it work with other PDFs? What size is the file in question (disc space and pages)?

Since you are only getting it with "specific documents", it's obvious there is "something" in THOSE documents that ITextSharp cannot handle.

Expecting the community to solve this particular problem given the available information is impossible.

You need to figure out yourself what is "different" about these documents (from the ones that "work").

(Or, change the int32 to an int64 and deal with the consequences of that).

.... I thinkx the problem is actually thrown in the iTextSharp package, that error seems to match the GIT source code

throw new invalidPdfException(MessageLocalization.GetComposedMessage("rebuild.failed...");

You'll need to report this as a bug on the GitHub repo. You'll need to provide them with a copy of a document that triggers the bug, and the sample code to reproduce it.
