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.

I also noted that iText looked to be a little more complex, and I was correct. However, iTextSharp does not suffer some of the performance drawbacks inherent to PdfBox, at least on the.

As I observed in my previous post, PdfBox. While I found it very cool to be able to run Java code in a. NET context, there was a serious performance hit, most notably the first time the PdfBox library was called, and the massive IKVM library spun up what amounts to a.

Needless to say, iTextSharp does not suffer this limitation. One of the most common tasks we need to do is extract pages from one Pdf into a new file. My simplified understanding of how this works is as follows: The PdfReader instance contains the content of the source PDF file. The Document class, once initialized with the PdfReader instance and a new output FileStream , essentially becomes a container into which pages extracted from the source file represented in the PdfReader class will be copied.

The result is then output to the Filestream , and saved to disk at the location specified by the destination file name. You can download the iTextSharp source code and binaries as a single package from Files page at the iTextSharp project site.

Extract the files from the. Next, set a reference in your project to the itextsharp. You will need to browse to the folder where you stashed the extracted contents of the iTextSharp download. Add the following using statements at the top of the file:. If we want to be able to a range of contiguous pages, we might add another method defining a start and end point:. What if we want non-contiguous pages from the source document?

Well, we might override the above method with one which accepts an array of ints representing the desired pages:. Obviously, the example s above are a simplistic first exploration of what appears to be a powerful library.

I believe this is as much to do with the nature of the PDF file format, and possibly the structure of lower-level libraries upon which iTextSharp is built. That said, there is without a doubt much to be discerned by exploring the iTextSharp source code.

Additionally, there are a number of resources to assist the erstwhile developer in using this library:. Lastly, there is a book authored by one of the primary contributors to the iText project, Bruno Lowagie:.

In this article i will show you how to merge multiple pdfs into one using ITextSharp below is the two approach one is to pass your input files path, output file path will be created if not exist and another is pass direct input stream, output stream and it will write the merge files into output stream. ITextSharp provides a rich library for PDFs operation, below is the method named MergePDFs it takes two argument first is the output file path absolute path and second it the input file path which is a params type parameter it means you can pass multiple input file path into it.

NET platform. Following on from my last Farm Solution, I have extended the solution by adding another button that when clicked, it looks up the document library and grabs all pdf files. Looping through each file, copies each pdf to a memory stream, once it have completely looped through each file, it then saves the file back to the SharePoint library. The advantage of using ITextSharp dll, is that you could create a provider hosted SharePoint App, and therefore create this merge functionality in Office First thing we need to do is add the itextsharp to the Visual Studio project.
