Rotate Barcode Image

Aspose.BarCode for JasperReports allows developers to rotate the barcode image by calling the setRotationAngle() method of the BarCodeAttributes class. The effects of some rotation angles are demonstrated in the figure below.

The barcode below is rotated 180 degrees. It is the output of the sample code shown below.

Barcode rotated 180 degrees

Programming Sample

Java

public class MyAttributes

{

    public static BarCodeAttributes Create(String text, String symbology)

    {

        BarCodeAttributes b = new BarCodeAttributes();

        b.setCodeText(text);

        b.setSymbology(symbology);

        //Roate clockwise for 180 degree (upside down)

        b.setRotationAngle(180);

        return b;

    }

}
