Configure Barcode Settings (Code93Options)

Use the Code93Options class to configure code 93 barcode settings.

The following code snippet creates an Code 93 barcode and customizes its options:

C#

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

var code93Options = new Code93Options();
code93Options.ShowText = true;
code93Options.Padding = new Padding(5);
code93Options.BorderWidth = 1;
code93Options.CalculateChecksum = true;

using var code93OptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_code93.png"), FileMode.Create, FileAccess.Write);
using var code93OptionsGenerator = new BarcodeGenerator(code93Options);

code93OptionsGenerator.Export("CODE93-123", code93OptionsStream, DXImageFormat.Png);

VB.NET

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

Dim code93Options As New Code93Options()
code93Options.ShowText = True
code93Options.Padding = New Padding(5)
code93Options.BorderWidth = 1
code93Options.CalculateChecksum = True

Using code93OptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_code93.png"), FileMode.Create, FileAccess.Write)
  Using code93OptionsGenerator As New BarcodeGenerator(code93Options)
    code93OptionsGenerator.Export("CODE93-123", code93OptionsStream, DXImageFormat.Png)
  End Using
End Using

Configure Barcode Settings (Fluent API)

Use the Code93OptionsBuilder class to configure code 93 barcode settings with Fluent API.

The following code snippet creates an Code 93 barcode and customizes its options:

C#

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

var code93Options = Code93OptionsBuilder.Create()
    .WithShowText(true)
    .WithPadding(5)
    .WithBorderWidth(1)
    .WithCalculateChecksum(true)
    .Build();

using var code93OptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_code93.png"), FileMode.Create, FileAccess.Write);
using var code93OptionsGenerator = new BarcodeGenerator(code93Options);

code93OptionsGenerator.Export("CODE93-123", code93OptionsStream, DXImageFormat.Png);

VB.NET

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

Dim code93Options = code93OptionsBuilder.Create() _
    .WithShowText(True) _
    .WithPadding(5) _
    .WithBorderWidth(1) _
    .WithCalculateChecksum(True) _
    .Build()

Using code93OptionsStream = New FileStream(Path.Combine(outDir, "barcode_symbology_code93.png"), FileMode.Create, FileAccess.Write)
  Using code93OptionsGenerator = New BarcodeGenerator(code93Options)
    code93OptionsGenerator.Export("CODE93-123", code93OptionsStream, DXImageFormat.Png)
  End Using
End Using
