Barcode Generation and Recognition Tutorial
This tutorial explains how to use Aspose.BarCode for Java to generate a PDF417 barcode image and then read a barcode from this image.
In the task considered in this tutorial, we use Eclipse as the IDE, which is free and could be downloaded at: http://www.eclipse.org/downloads/
Start Eclipse and create a new Java project
Creating a new Java project
Call the project Demo and click Finish
We will configure the library later.
Naming the project
Right-click on the project we have just created and select required properties
Setting project properties
Click on the Java Build Path item and select the Libraries tab
Click Add external Jars
In the opened file dialog, locate Aspose.BarCode.jar and Servlet-api.jar. They are available in the lib directory of the download package of Aspose.BarCode for Java
Right-click on the Demo project and select New and then Class at Package Explorer.
Creating a new class
Let this new class be an Applet and name it “Test”
Setting properties for the new class
- Add the code to generate a PDF417 barcode:
- Right-click on this class in the package explorer and select Run As and Java Applet
- Save the image to a file. Continuing the sample above, add this code to save the generated barcode image to a file:
Continuing the sample above, we can add the code to read a barcode from an image:
The evaluation version of Aspose.BarCode for Java allows decoding only Code 39 barcodes without limitations. To test the reading speed and accuracy for other symbologies, please use the demo JAR provided in the download package.
