NET Page. NET platform. It is implemented as an assembly. It must be noted that the assembly is coded and compiled using the. NET Framework 1. You might want to migrate to the version 2.

NET Framework. With a some more research on PDF merging. I was able to create a class that will make use of the ITextSharp assembly and perform as the merge pdf operation as needed.

Create ;. SetPageSize reader. GetPageSizeWithRotation 1 ; document. NewPage ;. SetLocalDestination filename ; document. AddTemplate page, 0, -1f, 1f, 0, 0, reader. GetPageSizeWithRotation i.

The code is pretty much self decribed. If there is any question, i can always be contacted via this post. PutNextEntry entry ; pdfFileContents. GetInstance document, outputStream ;. IsNullOrEmpty file. FileName : new PdfReader file.

Content ;. GetPageRotation i ;. I have tried merging the pdfs to letter size. The first was merged exactly to letter size. Can you please let me know how to merge pdfs to letter size irrespective of their size and content. Thanks in advance. I am trying to merge 2 pdf file and result will be a new pdf.

But content of 1st pdf file copy on second pdf file and content of second pdf file get removed. Praveen Kumar E-Bix software Pvt. I think you will need to determine the size and then do the merging. This looks very good… although pages with degrees rotation appear up-side-down, any solution to this? AddTemplate page, 0, -1f, 1f, 0, 0, rdr.

AddTemplate page, 0, 1f, -1f, 0, rdr. But now fixing one problem ends up with another problem… the PDF that is generated is 3 times larger than merging the files using Adobe Reader. Any solution or reasons why?

I was able to get this code to work this morning. Thanks very much. First of all, great tool!! Doc1 page 1 — Portrait Doc1 page 2 — Portrait Doc2 page 1 — Portrait Doc2 page 2 — Landscape Doc2 page 3 — Landscape Doc2 page 4 — Landscape Doc2 page 5 — Portrait Doc3 page 1 — Portrait When I merge these, the 3 pages that are landscape, end up with the page oriented as portrait, but the contents oriented as landscape.

This causes the text to get cut off on the pages that should have been landscape. I can force the text to orient correctly so printing would be correct , but that means that all of teh pages are portrait, just with rotated text, which is lousy for reading on the screen.

Any suggestions??? The thing is that the module will take the first page as screen orientation. That is:. If Doc2 — Page 1 is Portrait, it will be portrait all throughout. I you want to to be Landscape the first page should be Landscape. This is really just a tweak. Did you use the latest version of ITextReader available? If yes, then the code in this post needs to be modified to account for the page orientation differently.

It is not a big deal to use something that is well intended for developpers to use and ofcourse that it cost money. Anyone here knows other free pdf resources that can be used for pdf documents merging?

Merge pdf files using C#

I recently posted about using PdfBox. This time, I take a quick look at iTextSharp , another library for working with Pdf documents from within the. NET framework. This does come with a cost, however. The Pdf file format itself is complex; therefore, programming libraries which seek to provide a flexible interface for working with Pdf files become complex by default. I noted in my previous post on PdfBox that PdfBox was a little easier for me to get up and running with, at least for rather basic tasks such as splitting and merging existing Pdf files.

The advantage of using ITextSharp dll, is that you could create a provider hosted SharePoint App, and therefore create this merge functionality in Office
