using DevExpress.BarCodes;
using DevExpress.Drawing;
using DevExpress.XtraPrinting.BarCode;
using System.Diagnostics;
using System.Drawing;
using System.Text;
// Create a QR code.
BarCode barCode = new BarCode();
barCode.Symbology = Symbology.QRCode;
barCode.CodeText = "https://www.devexpress.com";
barCode.BackColor = Color.White;
barCode.ForeColor = Color.Black;
barCode.RotationAngle = 0;
barCode.CodeBinaryData = Encoding.Default.GetBytes(barCode.CodeText);
barCode.Options.QRCode.CompactionMode = DevExpress.BarCodes.QRCodeCompactionMode.Byte;
barCode.Options.QRCode.ErrorLevel = QRCodeErrorLevel.Q;
barCode.Options.QRCode.ShowCodeText = false;
barCode.DpiX = 72;
barCode.DpiY = 72;
barCode.Module = 2f;
//Specify the frame settings.
RectangleQRFrameOptions frameOpt = new RectangleQRFrameOptions() {
FrameWidth = 4,
FrameColor = System.Drawing.Color.DarkRed,
Text = "Scan me",
TextAlignment = QRFrameTextAlignment.Baseline,
TextPosition = QRFrameTextPosition.Top,
CornerRadius = 5
};
barCode.Options.QRCode.FrameOptions = frameOpt;
// Save the barcode as an image.
barCode.Save("BarCodeImage.png", DXImageFormat.Png);
// Open the image in the default viewer.
Process.Start(new ProcessStartInfo("BarCodeImage.png") { UseShellExecute = true });
The resulting frame looks as follows:
