Code to be executed - Java


// Create an instane of the BarcodeGenerator class
BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code39);

// Specify the code text
generator.setCodeText("");

// Specify the X-dimension 
// the smallest width of the unit of BarCode bars or spaces
generator.getParameters().getBarcode().getXDimension().setMillimeters(2);

// Set codetext position
generator.getParameters().getBarcode().getCodeTextParameters().setLocation(CodeLocation.Below);

// Generate image
generator.generateBarCodeImage();
