What is iText? (C# and Java PDF Library Alternatives Using IronPDF)

The iText PDF library is a Java and .NET library for creating and manipulating PDF files. iText 7 is the advanced version of iText 5 and iTextSharp. It is a simpler, more performant, and extensible library that meets the growing challenges of today's PDF document processes and document needs, one add-on at a time.

iText Group NV

The iText 7 Core is an open-source PDF library that you can incorporate into your own applications for creating interactive forms. It is a rethinking of the successful engine used in iText 5 with a modular code structure that allows for future enhancements and expansion as well as easier scripting.

Features of the iText software library

The iText library has multiple features for business users:

  1. Create, read, and manipulate PDF documents
  2. Add digital signatures to PDF documents
  3. Fill out and flatten interactive PDF forms
  4. Add tags to PDF documents
  5. Create maps and books
  6. Add bookmarks, page numbers, watermarks, and other features to existing PDF documents
  7. It supports PDF documents in compliance with:
    • PDF specifications including PDF 2.0 (ISO 32000-2)
    • PDF/A (ISO 19005; PDF/A-1a/b, PDF/A-2a/b/u, PDF/A-3a/b/u)

About iText

iText is a technology company in the digital documents space. The company’s flagship product is an open-source Java library and .NET library for creating and manipulating PDF documents in Java and .NET (C#).

Creating PDF documents using iText 7

Let's take a look at a hello world source code example of generating iText PDF documents.

// Import iText7 libraries
using iText.Kernel.Pdf;
using iText.Layout;
using iText.Layout.Element;

// Create a writer instance with the destination file path
var writer = new PdfWriter("destination.pdf");

// Create a PdfDocument instance which uses the writer
var pdf = new PdfDocument(writer);

// Create a Document instance for high-level manipulation
var document = new Document(pdf);

// Add a paragraph with "Hello World!" text
document.Add(new Paragraph("Hello World!"));

// Close the document to ensure changes are saved
document.Close();
// Import iText7 libraries
using iText.Kernel.Pdf;
using iText.Layout;
using iText.Layout.Element;

// Create a writer instance with the destination file path
var writer = new PdfWriter("destination.pdf");

// Create a PdfDocument instance which uses the writer
var pdf = new PdfDocument(writer);

// Create a Document instance for high-level manipulation
var document = new Document(pdf);

// Add a paragraph with "Hello World!" text
document.Add(new Paragraph("Hello World!"));

// Close the document to ensure changes are saved
document.Close();

Explanation:

  • PdfWriter: This object is responsible for writing the PDF file. It acts on a file path and writes the structures required for a valid PDF document.
  • PdfDocument: Communicates with the PdfWriter and manages the content and data structure in accordance with PDF standards.
  • Document: Provides high-level abstraction to handle content addition. It allows adding various PDF components like paragraphs, tables, etc.
  • Paragraph: Represents a text area to be inserted into the document.
  • The Close() method is crucial as it ensures all content is flushed and the file is correctly completed.

Limitations

iText 7 is paid and has limited functionalities. They do not provide all the functionalities in a single package. We need to use different libraries for different purposes. For instance:

PDF creation and PDF generation are supported by iText 7 while HTML to PDF Conversion is supported by pdfHTML. On the other side, PDF which includes removing sensitive data from PDF is supported by pdfSweep.

Data extraction such as extraction of images, tables, and text from PDF documents is provided by the pdf2Data library. RUPS supports PDF debugging to manipulate PDF documents.

Similarly, other features have libraries to support them, which are part of the iText 7 Suite. So, it is very difficult for the developer to manage so many DLLs.

Its commercial license is also very expensive. They have not mentioned the price on their iText 7 license and pricing page. We need to contact their sales department for the quotation, which will cost us time.

Let's suppose, if we are working on generating PDF documents, and at the same time we need to extract images, tables, or text from the existing PDF. In this case, we need to buy iText 7 Suite as well as iText pdf2Data which will cost us more.
