In this tutorial, we will explore the utilization of a widely-used annotation library to add replacement annotation in PDF using Java. We will provide a comprehensive, step-by-step guide that covers the installation of the annotation library and includes a code example. The replacement annotation stands out among various annotation types as it allows users to replace specific content within a PDF with alternative text. Below are the detailed steps to insert replacement annotation to PDF in Java.
Steps to Add Replacement Annotation in PDF using Java
- Install GroupDocs.Annotation for Java using Maven repository to insert the replacement annotation into PDF
- Add the necessary classes for adding the replacement annotation
- Instantiate an object of the Annotator class by passing the PDF file path as an argument to its constructor
- Instantiate a ReplacementAnnotation object and set its properties according to your requirements, such as position and page number
- Call the Annotator.add method, passing the ReplacementAnnotation object as an argument
- Use the Annotator.save method to save the resulting PDF file to disk
By following the aforementioned steps, the task to create replacement annotation in PDF using Java becomes simple. These instructions are compatible with popular operating systems such as Linux, Windows, and macOS, as long as Java is installed. The advantage of annotation library is that there is no need of additional software installation. The code example below illustrates how to insert a replacement annotation into a PDF.
