Create PDF files in Java : i. Text Tutorial. We have already learned about reading and writing excel files in java using apache POI library. In this tutorial, I am writing various code examples to create PDF files using i. Text library. These code examples are categorized into multiple sections based on the work they do OR functionality they achieve. With each example, I have attached a snapshot of PDF file so that you can visualize what exactly code is generating in PDF file. I have tried to put as many examples as I found useful to put here to help you all. If you think I am missing some more usecases, feel free to suggest me in comments area, I will add their examples in future. Table of Contents. Overview of i. Text library. Commonly used classesi.

Also, the structure of i. Text allows you to generate any of the above- mentioned types of documents with the same code. Isn’t it great feature, right? The i. Text library contains classes to generate PDF text in various fonts, generate tables in PDF document, add watermarks to pages, and so on. There are many more features available with i.

In this application, I will create a PDF file with a single statement in content. Example contain adding images from file system as well as URLs. Also, I have added code to position the images within document. Example contains the usage of Fonts as well as chapter and sections as well. Here writer. set. Encryption() is used to set password to generated PDF. We need to add bouncy castle jars generating for password protected PDFs. I have added these jars in sourcecode of examples for this post. Following are several permission values: Pdf. Writer. ALLOW. For example Pdf. Writer. ALLOW. In this example, I will read an PDF file and add some random content to it’s all pages. This will be needed when you want to stream the PDF file in a client- server environment. Leave a comment if something is not clear to you OR you would like to add any other example into this list.
