Apache PDFBox is an open source pure-Java library that can be used to create, render, print, split, merge, alter, verify and extract text and meta-data of PDF files.
This example covers the following topics
- Create a PDF document
- Add document properties such as Author, Title, Creation Date, Page Size, etc.
- Add Label Text with various font size and style
- Add Paragraph Text
- Draw lines and rectangle to create design layouts
- Insert an Image such as Company Logo
