The more data placed into a barcode, the larger it will become. To decrease the size, you could decrease the font size. To learn more about QR Code, view the QR Code FAQ.


Example of the java encoder class for the QR Code Font and Encoder. The code in bold are the properties that can be modified in your project.



import java.io.*;
import com.idautomation.fontencoder.qrcode.*;
class QRCodeBarcodeExample
{
public static void main ( String [] args )
{
String dataToEncode = "QRCode Test";
QRCodeEncoder qre= new QRCodeEncoder();
String DataToEncode = "IDAutomation Inc.";
boolean ApplyTilde = false;
int EncodingMode = 0;
int Version = 0;
int ErrorCorrectionLevel = 0;

System.out.println( qre.FontEncode(DataToEncode, ApplyTilde, EncodingMode,
Version, ErrorCorrectionLevel) );
}
}
