iTextSharp is a powerful and versatile library for creating and manipulating PDF documents in .NET applications. If you’re new to iTextSharp, this beginner’s guide will help you get started with the basics and provide you with some useful tips and tricks along the way.
To begin using iTextSharp, you’ll first need to download and install the library. You can find the latest version of iTextSharp on the official Website, along with the necessary documentation and examples. Once you’ve downloaded the library, you can add IT to your project by referencing the iTextSharp assembly.
After adding the iTextSharp assembly to your project, you’re ready to start creating PDF documents. The first step is to create an instance of the Document class, which represents the PDF document you want to create. You can specify the dimensions of the document by passing a Rectangle object to the Document constructor.
Once you have created the Document object, you can open IT using the Open() method. This method takes a Stream object as a parameter, which will be used to write the contents of the PDF document. You can use a FileStream object to write the document to a file, or a MemoryStream object if you want to store the document in memory.
With the document open, you can start adding content to IT. iTextSharp provides a wide range of classes and methods for creating text, images, tables, and other elements in a PDF document. For example, you can use the Paragraph class to create paragraphs of text, and the Image class to add images to the document.
Once you have finished adding content to the document, you need to close IT using the Close() method. This method will finalize the document and write its contents to the underlying Stream object. After closing the document, you can save IT to a file or send IT to the client browser for download.
iTextSharp also provides various options for customizing the appearance of the PDF document. You can set the page size and margins, specify the font and size of the text, and control many other aspects of the document’s layout and design. The library supports a wide range of fonts, including TrueType, Type 1, and OpenType fonts.
In addition to creating new documents, iTextSharp can also be used to manipulate existing PDF documents. You can open an existing document using the PdfReader class, which provides methods for reading the contents of a PDF file. You can then modify the document by adding, updating, or deleting pages, annotations, form fields, and other elements.
iTextSharp also supports other advanced features, such as digital signatures, encryption, and form filling. You can use the library to sign PDF documents with digital certificates, encrypt them to protect sensitive information, and fill out interactive form fields programmatically.
