Configure Barcode Settings (MicroQRCodeOptions)

Use the MicroQRCodeOptions class to configure Micro QR Code barcode settings.

The following code snippet creates the Micro QR Code barcode and specifies its settings:

C#

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

var microQrOptions = new MicroQRCodeOptions();
microQrOptions.CompactionMode = MicroQRCodeCompactionMode.Byte;
microQrOptions.ErrorCorrectionLevel = MicroQRCodeErrorCorrectionLevel.Auto;
microQrOptions.BackColor = Color.LightGray;
microQrOptions.ShowText = false;
microQrOptions.Padding = new Padding(5);
microQrOptions.BorderWidth = 1;
microQrOptions.BorderColor = Color.Blue;

using var microQrOptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_micro_qr_code.png"), FileMode.Create, FileAccess.Write);
using var microQrOptionsGenerator = new BarcodeGenerator(microQrOptions);
microQrOptionsGenerator.Export("HELLO123", microQrOptionsStream, DXImageFormat.Png);

VB.NET

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

Dim microQrOptions As New MicroQRCodeOptions()
microQrOptions.CompactionMode = MicroQRCodeCompactionMode.Byte
microQrOptions.ErrorCorrectionLevel = MicroQRCodeErrorCorrectionLevel.Auto
microQrOptions.BackColor = Color.LightGray
microQrOptions.ShowText = False
microQrOptions.Padding = New Padding(5)
microQrOptions.BorderWidth = 1
microQrOptions.BorderColor = Color.Blue

Using microQrOptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_micro_qr_code.png"), FileMode.Create, FileAccess.Write)
    Using microQrOptionsGenerator As New BarcodeGenerator(microQrOptions)
        microQrOptionsGenerator.Export("HELLO123", microQrOptionsStream, DXImageFormat.Png)
    End Using
End Using

Configure Barcode Settings (Fluent API)

Use the MicroQRCodeOptionsBuilder class to configure Micro QR Code barcode settings with Fluent API.

The following code snippet creates the Micro QR Code barcode and specifies its settings:

C#

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

var microQRCode = MicroQRCodeOptionsBuilder.Create()
    .WithCompactionMode(MicroQRCodeCompactionMode.Byte)
    .WithErrorCorrectionLevel(MicroQRCodeErrorCorrectionLevel.Auto)
    .WithBackColor(Color.LightGray)
    .WithShowText(false)
    .WithPadding(5)
    .WithBorderWidth(1)
    .WithBorderColor(Color.Blue)
    .Build();

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

using var stream = new FileStream(filePath, FileMode.Create);
using var generator = new BarcodeGenerator(microQRCode);
generator.Export("HELLO123", stream, DXImageFormat.Png);

VB.NET

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

Module Module1
    Sub Main()
        Dim microQRCode = MicroQRCodeOptionsBuilder.Create() _
            .WithCompactionMode(MicroQRCodeCompactionMode.Byte) _
            .WithErrorCorrectionLevel(MicroQRCodeErrorCorrectionLevel.Auto) _
            .WithBackColor(Color.LightGray) _
            .WithShowText(False) _
            .WithPadding(5) _
            .WithBorderWidth(1) _
            .WithBorderColor(Color.Blue) _
            .Build()

        Dim filePath As String = Path.GetFullPath("microQr_barcode.png")

        Using stream As New FileStream(filePath, FileMode.Create)
            Using generator As New BarcodeGenerator(microQRCode)
                generator.Export("HELLO123", stream, DXImageFormat.Png)
            End Using
        End Using
    End Sub
End Module
