Configure Barcode Settings (Code93ExtendedOptions)

Use the Code93ExtendedOptions class to configure code 93 extended barcode settings.

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

C#

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

var code93ExtOptions = new Code93ExtendedOptions();
code93ExtOptions.ShowText = true;
code93ExtOptions.Padding = new Padding(5);
code93ExtOptions.BorderWidth = 1;
code93ExtOptions.CalculateChecksum = true;

using var code93ExtOptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_code93_extended.png"), FileMode.Create, FileAccess.Write);
using var code93ExtOptionsGenerator = new BarcodeGenerator(code93ExtOptions);

code93ExtOptionsGenerator.Export("Code93 ext: abcXYZ!?", code93ExtOptionsStream, DXImageFormat.Png);

VB.NET

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

Dim code93ExtOptions As New Code93ExtendedOptions()
code93ExtOptions.ShowText = True
code93ExtOptions.Padding = New Padding(5)
code93ExtOptions.BorderWidth = 1
code93ExtOptions.CalculateChecksum = True

Using code93ExtOptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_code93_extended.png"), FileMode.Create, FileAccess.Write)
  Using code93ExtOptionsGenerator As New BarcodeGenerator(code93ExtOptions)
    code93ExtOptionsGenerator.Export("Code93 ext: abcXYZ!?", code93ExtOptionsStream, DXImageFormat.Png)
  End Using
End Using

Configure Barcode Settings (Fluent API)

Use the Code93ExtendedOptionsBuilder class to configure code 93 extended barcode settings with Fluent API.

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

C#

using System.Drawing;

var code93ExtOptions = code93ExtOptionsBuilder.Create()
    .WithShowText(true)
    .WithPadding(5)
    .WithBorderWidth(1)
    .WithCalculateChecksum(true)
    .Build();

using var code93ExtOptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_code93_extended.png"), FileMode.Create, FileAccess.Write);
using var code93ExtOptionsGenerator = new BarcodeGenerator(code93ExtOptions);

code93ExtOptionsGenerator.Export("Code93 ext: abcXYZ!?", code93ExtOptionsStream, DXImageFormat.Png);

VB.NET

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

Dim code93ExtOptions = code93ExtOptionsBuilder.Create() _
    .WithShowText(True) _
    .WithPadding(5) _
    .WithBorderWidth(1) _
    .WithCalculateChecksum(True) _
    .Build()

Using code93ExtOptionsStream = New FileStream(Path.Combine(outDir, "barcode_symbology_code93_extended.png"), FileMode.Create, FileAccess.Write)
  Using code93ExtOptionsGenerator = New BarcodeGenerator(code93ExtOptions)
    code93ExtOptionsGenerator.Export("Code93 ext: abcXYZ!?", code93ExtOptionsStream, DXImageFormat.Png)
  End Using
End Using
