Configure Barcode Settings (EAN128Options)

Use the EAN128Options class to configure EAN-128 barcode settings.

The following code snippet creates an EAN128 barcode and customizes its options:

C#

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

var code128Options = new Code128Options();
code128Options.ShowText = true;
code128Options.Charset = Code128CharacterSet.CharsetB;
code128Options.AddLeadingZero = true;
code128Options.Padding = new Padding(5);
code128Options.BorderWidth = 1;
code128Options.FNC1Substitute = "<FNC1>";
code128Options.FNC2Substitute = "<FNC2>";
code128Options.FNC3Substitute = "<FNC3>";

using var code128OptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_code128.png"), FileMode.Create, FileAccess.Write);
using var code128OptionsGenerator = new BarcodeGenerator(code128Options);
code128OptionsGenerator.Export("<FNC1>12345<FNC2>67<FNC3>89", code128OptionsStream, DXImageFormat.Png);

VB.NET

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

Dim code128Options As New Code128Options()
code128Options.ShowText = True
code128Options.Charset = Code128CharacterSet.CharsetB
code128Options.AddLeadingZero = True
code128Options.Padding = New Padding(5)
code128Options.BorderWidth = 1
code128Options.FNC1Substitute = "<FNC1>"
code128Options.FNC2Substitute = "<FNC2>"
code128Options.FNC3Substitute = "<FNC3>"

Using code128OptionsStream As New FileStream(Path.Combine(outDir, "barcode_symbology_code128.png"), FileMode.Create, FileAccess.Write)
  Using code128OptionsGenerator As New BarcodeGenerator(code128Options)
    code128OptionsGenerator.Export("<FNC1>12345<FNC2>67<FNC3>89", code128OptionsStream, DXImageFormat.Png)
  End Using
End Using

Configure Barcode Settings (Fluent API)

Use the EAN128OptionsBuilder class to configure EAN-128 barcode settings with Fluent API.

The following code snippet creates an EAN128 barcode and customizes its options:

C#

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

var ean128Options = EAN128OptionsBuilder.Create()
    .WithShowText(false)
    .WithPadding(5)
    .WithBorderWidth(1)
    .Build();

using var ean128OptionsStream = new FileStream(Path.Combine(outDir, "barcode_symbology_ean128.png"), FileMode.Create, FileAccess.Write);
using var ean128OptionsGenerator = new BarcodeGenerator(ean128Options);

ean128OptionsGenerator.Export("(01)09521234543213(10)ABC123", ean128OptionsStream, DXImageFormat.Png);

VB.NET

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

Dim ean128Options = EAN128OptionsBuilder.Create() _
    .WithShowText(False) _
    .WithPadding(5) _
    .WithBorderWidth(1) _
    .Build()

Using ean128OptionsStream = New FileStream(Path.Combine(outDir, "barcode_symbology_ean128.png"), FileMode.Create, FileAccess.Write)
  Using ean128OptionsGenerator = New BarcodeGenerator(ean128Options)
    ean128OptionsGenerator.Export("(01)09521234543213(10)ABC123", ean128OptionsStream, DXImageFormat.Png)
  End Using
End Using
