PDF417 (Portable Data File) is a stacked linear two-dimensional barcode. It is used in different fields, including transport, postal, identification card, and inventory management.

For more information on this symbology, refer to its Official Standard.

Add the Bar Code to a Report

1. Drag the XRBarCode item from the DX.24.1: Report Controls tab and drop it onto the report.

   

2. Set the XRBarCode control’s Symbology property to PDF417 (an object of the PDF417Generator type).

   

3. Specify common barcode properties and properties specific to PDF417.

Specific Properties

• XRBarCode.AutoModule/BarCodeControl.AutoModule

  Gets or sets whether the Module property value should be calculated automatically based on the barcode size.

• Columns

  Gets or sets the number of bar code columns, which allows control of the logic width of the bar code.

• CompactionMode

  Gets or sets whether text or binary mode should be used to encode the barcode’s data.

• ErrorCorrectionLevel

  Gets or sets the amount of redundancy built into the bar code’s coding, to compensate for calculation errors.

• Rows

  Gets or sets the number of bar code rows, which allows control of the logic height of the bar code.

• TruncateSymbol

  Gets or sets whether the special end-symbol should be appended to the bar code.

• YToXRatio

  Gets or sets the height-to-width ratio of a logical unit’s graphic representation.

Runtime Example

The following code creates the PDF417 barcode and specifies its properties.

The code example below shows how to create a report with the PDF417 barcode:

C#

using DevExpress.XtraPrinting.BarCode;
using DevExpress.XtraReports.UI;
//...

var barCode = CreatePDF417BarCode("012345678");

var report = new XtraReport() {
    Bands = {
        new DetailBand() {
            Controls = { barCode }
        }
    }
};

VB.NET

Imports DevExpress.XtraPrinting.BarCode
Imports DevExpress.XtraReports.UI
'...

Private barCode = CreatePDF417BarCode("012345678")

Dim report As New XtraReport()
Dim band = New DetailBand()
band.Controls.Add(barCode)
