Configure Barcode Settings (QRGS1Options)

Use the QRGS1Options class to configure QR GS1 barcode settings.

The following code snippet creates a QR Code GS1 barcode and specifies its settings:

C#

using DevExpress.Docs.Barcode;
using DevExpress.Drawing;
using System.Drawing;

using var fileStream = new FileStream("logo.png", FileMode.Open);

var qrGs1Options = new QRCodeGS1Options();
qrGs1Options.ErrorCorrectionLevel = QRCodeErrorCorrectionLevel.H;
qrGs1Options.CompactionMode = QRCodeCompactionMode.Auto;
qrGs1Options.IncludeQuietZone = true;
qrOptions.Logo = DXImage.FromStream(fileStream);
qrGs1Options.Version = QRCodeVersion.Version20;
qrGs1Options.BackColor = Color.LightGray;
qrGs1Options.ShowText = false;
qrGs1Options.ModuleSize = 50;
qrGs1Options.Padding = new Padding(5);
qrGs1Options.BorderWidth = 1;
qrGs1Options.BorderColor = Color.Blue;

using var qrGs1OptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_qr_gs1_code.png"),
    FileMode.Create, FileAccess.Write);
using var qrGs1OptionsGenerator = new BarcodeGenerator(qrGs1Options);
qrGs1OptionsGenerator.Export("(01)09521234543213(8200)https://www.devexpress.com", qrGs1OptionsStream, DXImageFormat.Png);

VB.NET

Imports DevExpress.Docs.Barcode
Imports DevExpress.Drawing
Imports System.Drawing
Imports System.IO

Using fileStream As New FileStream("logo.png", FileMode.Open)
    qrGs1Options.Logo = DXImage.FromStream(fileStream)
End Using

Dim qrGs1Options As New QRCodeGS1Options()
qrGs1Options.ErrorCorrectionLevel = QRCodeErrorCorrectionLevel.H
qrGs1Options.CompactionMode = QRCodeCompactionMode.Auto
qrGs1Options.IncludeQuietZone = True
qrGs1Options.Version = QRCodeVersion.Version20
qrGs1Options.BackColor = Color.LightGray
qrGs1Options.ShowText = False
qrGs1Options.ModuleSize = 50
qrGs1Options.Padding = New Padding(5)
qrGs1Options.BorderWidth = 1
qrGs1Options.BorderColor = Color.Blue

Using qrGs1OptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_qr_gs1_code.png"),
    FileMode.Create, FileAccess.Write)
    Using qrGs1OptionsGenerator As New BarcodeGenerator(qrGs1Options)
        qrGs1OptionsGenerator.Export("(01)09521234543213(8200)https://www.devexpress.com", qrGs1OptionsStream, DXImageFormat.Png)
    End Using
End Using

Configure Barcode Settings (Fluent API)

Use the QRGS1OptionsBuilder class to configure QR GS1 barcode settings with Fluent API.

The following code snippet creates a QR Code GS1 barcode and specifies its settings:

C#

using DevExpress.Docs.Barcode;
using DevExpress.Drawing;
using System.Drawing;

var qrgs1code = QRCodeGS1OptionsBuilder.Create()
    .WithErrorCorrectionLevel(QRCodeErrorCorrectionLevel.M)
    .WithCompactionMode(QRCodeCompactionMode.Auto)
    .WithIncludeQuietZone(true)
    .WithLogo(DXImage.FromStream(new FileStream("logo.png", FileMode.Open)))
    .WithVersion(QRCodeVersion.Version20)
    .WithBackColor(Color.LightGray)
    .WithShowText(false)
    .WithPadding(5)
    .WithBorderWidth(1)
    .WithBorderColor(Color.Blue)
    .Build();

var filePath = Path.GetFullPath("qrgs1_code.png");

using var stream = new FileStream(filePath, FileMode.Create);
using var generator = new BarcodeGenerator(qrgs1code);
generator.Export("(01)09521234543213(8200)https://www.devexpress.com", stream, DXImageFormat.Png);

VB.NET

Imports DevExpress.Docs.Barcode
Imports DevExpress.Drawing
Imports System.Drawing
Imports System.IO

Dim qrgs1code = QRCodeGS1OptionsBuilder.Create() _
    .WithErrorCorrectionLevel(QRCodeErrorCorrectionLevel.M) _
    .WithCompactionMode(QRCodeCompactionMode.Auto) _
    .WithIncludeQuietZone(True) _
    .WithLogo(DXImage.FromStream(New FileStream("logo.png", FileMode.Open))) _
    .WithVersion(QRCodeVersion.Version20) _
    .WithBackColor(Color.LightGray) _
    .WithShowText(False) _
    .WithPadding(5) _
    .WithBorderWidth(1) _
    .WithBorderColor(Color.Blue) _
    .Build()

Dim filePath = Path.GetFullPath("qrgs1_code.png")

Using stream As New FileStream(filePath, FileMode.Create)
    Using generator As New BarcodeGenerator(qrgs1code)
        generator.Export("(01)09521234543213(8200)https://www.devexpress.com", stream, DXImageFormat.Png)
    End Using
End Using
