Splitting and Merging PDF Files in C# Using i. Text. Sharp. Splitting and merging PDF files in C# using the i. Text. Sharp library. I recently posted about using Pdf.

Some Navigation Aids: What is i. Text. Sharp? i. Text. Sharp is a direct . Basic PDF Creation Using iTextSharp - Part I. By Micke Blomquist on Mar 11, 2011.

Im looking to create a script that will merge multiple PDF's into 1 final PDF. I have seen that iTextSharp might be able to do this. Any one got any pointers where to start or even better any examples? This article, by Scott Mitchell, shows how to programmatically create PDF documents using ASP.NET and the free, open source iTextSharp library. How to Merge PDF C# and merge PDF VB.NET.

As the project’s summary page on Source. Forge states, i. Text “ . 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 Pdf. Box that Pdf. Box 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 i. Text looked to be a little more complex, and I was correct. However, i. Text. Sharp does not suffer some of the performance drawbacks inherent to Pdf. Box, at least on the . As I observed in my previous post, Pdf. Box. net is NOT a direct port of the Pdf. Box Java library, but instead is a Java library running within . IKVM. 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 Pdf. Box library was called, and the massive IKVM library spun up what amounts to a . Net implementation of the Java Virtual Machine, within which the Java code of the Pdf. Box library is then executed. Needless to say, i. Text. Sharp 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. We’ll take a look at some relatively basic sample code which does just that, and get a feel for using the i. Text. Sharp programming model. In the following code sample, the primary i. Text. Sharp classes we will be using are the Pdf. Reader, Document, Pdf. Copy, and Pdf. Imported. Page classes. My simplified understanding of how this works is as follows: The Pdf. Reader instance contains the content of the source PDF file. The Document class, once initialized with the Pdf. Reader instance and a new output File. Stream, essentially becomes a container into which pages extracted from the source file represented in the Pdf. Reader class will be copied. Note that the Document class represents the Pdf content as HTML, which will be used to construct a properly formatted Pdf file. 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 i. Text. Sharp source code and binaries as a single package from Files page at the i. Text. Sharp project site. Just click on the “Download itextsharp- all- 5. Extract the files from the .

Add the following using statements at the top of the file: using i. Text. Sharp. text. Text. Sharp. text. Text. Tools. . If we want to be able to a range of contiguous pages, we might add another method defining a start and end point: publicvoid Extract. Pages(string source. Pdf. Path, string output. Pdf. Path. int start. Page, int end. Page). Well, we might override the above method with one which accepts an array of ints representing the desired pages: publicvoid Extract. Pages(string source. Pdf. Path. string output. Pdf. Path, int. What I notice about i. Text in general is that, unlike some API’s, the path to achieving your desired result is often not intuitive. 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 i. Text. Sharp is built. That said, there is without a doubt much to be discerned by exploring the i. Text. Sharp 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 i. Text project, Bruno Lowagie: Code. Project. John on Google. Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
