In this how-to tutorial, we describe the step-by-step procedure to add Barcode signature to PDF in Java. Further, it provides a sample code that demonstrates the implementation of how to add Barcode in PDF using Java capability. Here are the detailed instructions along with the working example for signing documents with a Barcode signature.

Steps to Add Barcode Signature to PDF in Java

1. Install GroupDocs.Signature for Java from the Maven repository in the Java project to sign PDF with Barcode signature
2. Add essential classes for the implementation to add Barcode to PDF
3. Create an instance of the Signature class and pass the input PDF to its constructor
4. Initialize BarcodeSignOptions class and pass the input string to the constructor
5. Call the Sign method of the Signature class, pass the output PDF file name and BarcodeSignOptions object to it

We have listed the points that allow users to easily create Barcode for PDF file using Java and use it for signing the documents. This feature can be developed by installing the required library from the Maven repository and importing the essential classes. In the next step, create instances of the Signature and BarcodeSignOptions class for loading the input PDF document and defining parameters for the Barcode signature. Finally, you can add Barcode signatures to the PDF file by calling the Sign method.

Code to Add Barcode Signature to PDF in Java

We have developed the above sample code to demonstrate the Java add Barcode to PDF capability. As you can see, we have created the Barcode signature and added it to the PDF document by writing three-four lines of the code and consuming a few API calls. Moreover, this sample code can be run on any operating system including MS Windows, Linux, and Mac OS.

We have discussed the detailed procedure on how to create a Barcode for a PDF and how to add Barcode code to PDF document. Recently, we published article on how to use Java to sign PDF with Image Signature, have a look at How to Add Image Signature to PDF in Java post for more information.
