Type Description

The Module property cannot be set to a value less than or equal to 0.

Note that if the Module property is set to a very small value, a bar code image may be unreadable by a scanner.

The code sample below creates a QR code and displays it in a PictureBox.

using System;
using System.Text;
using DevExpress.BarCodes;
using DevExpress.Drawing;
using DevExpress.Drawing.Extensions;

private void button1_Click(object sender, EventArgs e)
    this.pictureBox1.Image = null;

    BarCode barCode = new BarCode();
    barCode.Symbology = Symbology.QRCode;
    barCode.BackColor = Color.White;
    barCode.ForeColor = Color.Black;
    barCode.RotationAngle = 0;
    barCode.CodeBinaryData = Encoding.Default.GetBytes("");
    barCode.Options.QRCode.CompactionMode = QRCodeCompactionMode.Byte;
    barCode.Options.QRCode.ErrorLevel = QRCodeErrorLevel.Q;
    barCode.Options.QRCode.ShowCodeText = true;
    barCode.DpiX = 72;
    barCode.DpiY = 72;
    barCode.Module = 2f;

    this.pictureBox1.Image = barCode.BarCodeImage.ConvertToGdiPlusImage();
