Barcodes provide a quick and efficient way to encode data in a machine-readable format. Extracting barcodes from PDF files can be essential for automated data processing in industries like logistics, healthcare, and retail. In this blog post, we will explore how to extract barcodes from PDF documents using Java.
Why Extract Barcodes from PDFs?
There are various reasons why you might want to extract barcodes from PDF documents, including:
Automated Data Collection: Extracting barcodes from shipping labels, invoices, or product sheets can automate data entry processes.
Efficient Document Management: Barcodes embedded in PDFs can contain metadata like serial numbers or product codes, making document organization more efficient.
Integration with Enterprise Systems: Extracting barcodes can allow businesses to integrate their PDF documents with inventory, asset management, or logistics systems.
Read Barcodes in PDF - Java API Configuration
For reading barcodes in the PDF documents, you need to install Conholdate.Total for Java in your environment. Simply download the JAR file or use the below Maven configurations in the pom.xml file:
<dependency>
<groupId>com.conholdate</groupId>
<artifactId>conholdate-total</artifactId>
<version>24.6</version>
<type>pom</type>
</dependency>
Extract Barcode from PDF Documents in Java
The steps below show how to extract barcodes from PDF documents using Java:
- Parser Class Initialization: We create an instance of the Parser class to load the PDF file containing barcodes.
- Check Barcode Support: The getFeatures() method is called to check if the PDF document supports barcode extraction. If not, a message is displayed, and the process terminates.
- Extract Barcodes: If the document supports barcode extraction, we use the getBarcodes() method to extract the barcode information from the document.
- Iterate and Print: We iterate through each extracted barcode and print the page index and the barcode value.
The sample code below demonstrates how to extract barcodes from PDF files in Java:
Free Evaluation License
You may request a free temporary license to extract all barcode types and formats without any restrictions.
