The following code snippet creates the Intelligent Mail barcode and customizes its options:

C#

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

var imOptions = new IntelligentMailOptions();
imOptions.BackColor = Color.LightGray;
imOptions.ShowText = false;
imOptions.Padding = new Padding(5);
imOptions.BorderWidth = 1;
imOptions.BorderColor = Color.Blue;

using var imOptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_intelligent_mail.png"), FileMode.Create, FileAccess.Write);
using var imOptionsGenerator = new BarcodeGenerator(imOptions);
imOptionsGenerator.Export("92123912345678123456", imOptionsStream, DXImageFormat.Png);

VB.NET

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

Dim imOptions As New IntelligentMailOptions()
imOptions.BackColor = Color.LightGray
imOptions.ShowText = False
imOptions.Padding = New Padding(5)
imOptions.BorderWidth = 1
imOptions.BorderColor = Color.Blue

Using imOptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_intelligent_mail.png"), FileMode.Create, FileAccess.Write)
    Using imOptionsGenerator As New BarcodeGenerator(imOptions)
        imOptionsGenerator.Export("92123912345678123456", imOptionsStream, DXImageFormat.Png)
    End Using
End Using

Configure Barcode Settings (Fluent API)

Use the IntelligentMailOptionsBuilder class to configure Intelligent Mail barcode settings with Fluent API.

The following code snippet creates the Intelligent Mail barcode and customizes its options:

var mailCodeOptions = IntelligentMailOptionsBuilder.Create()
    .WithBackColor(Color.LightGray)
    .WithShowText(false)
    .WithPadding(5)
    .WithBorderWidth(1)
    .WithBorderColor(Color.Blue)
    .Build();

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

using var stream = new FileStream(filePath, FileMode.Create);
using var generator = new BarcodeGenerator(mailCodeOptions);
generator.Export("92123912345678123456", stream, DXImageFormat.Png);

VB.NET

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

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

        Using stream As New FileStream(filePath, FileMode.Create)
            Using generator As New BarcodeGenerator(mailCodeOptions)
                generator.Export("92123912345678123456", stream, DXImageFormat.Png)
            End Using
