NET web application, you will have to rely on one of the many third party components that are available. Google will help you to find one that fits your budget, as well as a range of open-source free components.
One of the free components is iTextSharpwhich is a port of a well known Java utility, iText. The main problem with iTextSharp is that it lacks documentation. There are some basic tutorials available, but most programmers have to resort to trying to wrestle with the documentation provided for the Java version – iText – to get going with the component, or you may want to purchase the book iText In Action.
However, this only provides guidance in Java. Many of the code samples are transferable to C without a lot of modification, but if you are relatively new to Cssve may frequently become frustrated with undocumented or inexplicable differences in classes and method names between the two versions. So, as part of a series of How To articles, here’s how to get started using iTextSharp with code samples in C. First thing to do is to install the Nuget package.
ASP.NET : How to Generate PDF from HTML with iTextSharp
The dll will be copied to your Bin directory, and is now available to the web site or project. Note that this link takes you to an older version of iTextSharp 4. The reason for that is that version 5 is available under a different licence that requires you to either asxp all of the source code of your application available as open source, or to purchase a commercial licence to use iTextSharp in itextsharrp projects.
Version 4 does not apply those restrictions. All of the articles I have written about iTextSharp are based on version 4. I have also added a folder called PDFs in which I plan itexthsarp store my generated files. To avoid typing full references to the dll, it is best to add a couple of using statements to the default ones in your code-behind:. You will awpx want to reference System. IOas you will be creating, opening and closing files, and classes in this namespace are required.
The principal object within iTextSharp is the Document object.
You need to create an instance of this to be able to work with otextsharp PDF in memory. So, the first thing to do is to instantiate one:. This creates a PDF document object in memory with the default settings. The size of the document by default is A4 which measures mm x mm, or 8. Margins are set at half an inch all round.
The next thing to do is to commit the document to disk. PdfWriter class is required for this:. Now to begin actually working with the document, open it, and add asppx new paragraph, then close it:. If you refresh the PDFs folder in your web site, you will see that a new item – Iyextsharp. It may be, however, that you don’t want to always create a PDF with the default size and margins, so iTextSharp provides ways for you to customise these settings.
There are 2 further constructors to the Document object:. Rectangle pageSize, floatfloatfloatfloat. If you sqve to apply a custom size that isn’t available within the PageSize class, you define your own Rectangle object, set its properties and pass that into the constructor as an argument:. Add new Paragraph “This is a custom size”.
In this case, a PDF document was created with the width being points, and the height set at points. There are 72 points to an inch, so this particular document isn’t very large. It’s in fact 1. You will probably find that as well as iTextSharp. The second constructor which takes a Rectangle itexrsharp and a series of 4 float values allows you to set your custom margins through the floats.
Again, these values are measured in points. The default half inch margins are 36 points. If you use the PageSize class constructor, or a Rectangle directly, you can also set the background colour of the document.
It used to be that aave you wanted to prepare a PDF for printing by a professional lithographic printer, you had to ensure that all colours were CMYK, but with greater adoption of digital printing by printing companies, RGB is becoming more acceptable.
Certainly, for display on the web, RGB is preferred. To set the background colour, we use the BackgroundColor property of the Rectangle object:.
This article has introduced iTextSharp, and should have provided a starting point. Subsequent articles examine a range of functionality and features offered by this rather natty component.
