In this quick tutorial, we’ll focus on creating PDF documents from scratch based on the iText and PdfBox libraries.
First, we need to include the following Maven dependencies in our project: The latest version of the libraries can be found here: iText and PdfBox. It’s important to know that iText is available under the open-source AGPL license, as well as a commercial license. If we purchase a commercial license, we can keep our source code to ourselves, allowin...
iText and PdfBox are both Java libraries that we use for the creation and manipulation of pdf files. Although the final output of the libraries is the same, they operate in a different manner. Let’s take a closer look at each of them.
4.1. Insert Text in Pdf
Let’s look at how we insert a new file with “Hello World” text into a pdf file: Creating a pdf with the use of the iText library is based on manipulating objects implementing the Elements interface in Document (in version 5.5.10 there are 45 of those implementations). The smallest element we can add to the document and use is Chunk, which is basically a string with the applied font. Additionally, we can combine Chunks with other elements, like Paragraphs, Section,etc., resulting in nice looki...
4.2. Inserting Image
The iText library provides an easy way to add an image to the document. We simply need to create an Image instance and add it to the Document:
4.3. Inserting Table
We may face a problem if we want to add a table to our pdf. Luckily, iText provides this functionality out-of-the-box. First, we need to create a PdfTable object and provide a number of columns for our table in the constructor. Then we can simply add new cells by calling the addCellmethod on the newly created table object. iText will create table rows as long as all the necessary cells are defined. This means that once we create a table with three columns, and add eight cells to it, only two...
5.1. Insert Text in Pdf
In contrast to iText, the PdfBox library provides an API based on stream manipulation. There are no classes like Chunk/Paragraph, etc. The PDDocument class is an in-memory Pdf representation, where the user writes data by manipulating PDPageContentStreamclass. Let’s take a look at the code example:
5.2. Inserting Image
Inserting images is also straightforward. We need to load a file and create a PDImageXObject, subsequently drawing it on the document (need to provide exact x, y coordinates):
5.3. Inserting a Table
Unfortunately, PdfBoxdoesn’t provide any out-of-the-box methods that allow us to create tables. What we can do in this situation is draw it manually, literally drawing each line until our drawing resembles our desired table.
