Set Aspect Ratio

A barcode’s aspect ratio is the width:height ratio. We can control how tall or wide a barcode is by controlling its aspect ratio.

Setting Aspect Ratio

An aspect ratio of 3:2 means that the barcode is 1.5 or 3/2 times wider than it is tall. In other words, the width of the barcode is 1.5 times larger than the height. Below is a Pdf417 barcode with an aspect ration of 1.5

An aspect ratio of 2 means that the barcode’s width is twice its height. Below is a Pdf417 barcode with an aspect ratio of 2.

The code below shows how to set the aspect ratio in Java.

Java

 public class MyAttributes

{

    public static BarCodeAttributes Create(String text, String symbology)

    {

        BarCodeAttributes b = new BarCodeAttributes();

        b.setCodeText(text);

        b.setSymbology(symbology);

        // Set Aspect Ratio to 3:2 or 1.5

        b.setPDF417AspectRatio(1.5f);

        return b;

    }

}
