I recently posted about using PdfBox.
This time, I take a quick look at iTextSharpqppend library for working with Pdf documents from within the. 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 itexstharp to do is extract pages from one Pdf into a new file.
My simplified understanding of how this works is as follows: The Document class, once initialized with the PdfReader instance and a new output FileStreamessentially becomes a container into which pages extracted itextzharp the source file represented in the PdfReader class will be copied. The result is then output to the Filestreamand 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. The complete example code for this post is available at my Github Repo. 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?
iTextSharp – append to existing pdf
Well, we might override the above method with one which accepts an itextsbarp of ints representing the desired pages:. Obviously, the example s above are a simplistic first exploration of what appears itsxtsharp 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:.
