The Avapose Java 2D Barcode reader is 100% written in Java and support JDK 1.4.2 and above. The barcode recognition library is the best Java two-dimensional barcode image reading component in the market. We provide full functionality to read most popular 2D/two-dimensional barcode QR Code, PDF417 and Data Matrix barcode.
This 2D barcode reader library for Java is able to decode two-dimensional barcodes from scanned documents, stream or image files such as BMP, JPG, PNG, TIFF, GIF and Java AWT image objects in your Java applications.
Add barcode decoder API to Java projects to read 2D barcodes
It is really easy to scan and read two-dimensional barcodes in images by using the Avapose 2D/two-dimensional barcode recognition Java toolkit. The below steps is a brief guide to use the Java 2D barcode reader SDK.
  1. Download the 2D barcode reading Java component package from the following download link
  2. Unzip the Java 2D barcode reader package and copy the 2D barcode reader jar file to your Java project classpath
  3. Use the below sample code to tell the Java 2D barcode reader class where the two-dimensional barcode image file is and what the 2D barcode type is

    String[] datas = File("C:/barcode.jpg"), BarcodeReader.QRCODE);
  4. Pass the 2D barcode image file and two-dimensional barcode type to the Java 2D/two-dimensional barcode reader, which will return the barcode data value
Avapose offers detailed User Guide for developers to use the 2D/two-dimensional Barcode recognition SDK in Java developmental environments to scan and read 2D/two-dimensional barcode image in Java projects. Please check out the
