PDF barcode is mainly used in commodity transaction which, to a large extent, increases efficiency and escapes human errors. The most frequently case we use barcode is that when we go shopping in the supermarket, the operator only needs to scan the barcodes, the price of the goods will automatically show. Obviously, all the information has been input in the customer data table system. Through barcode, people can easily find the details of a good in a short time. Since barcode is so wonderful, let me share a solution to draw barcode in PDF document.
Spire.PDF for WPF enables users to easily draw barcode in PDF document with C#, VB.NET for WPF. Before you start, please freely Download Spire.PDF (Spire.Office) and install it with .NET Framework 2.0 (or above) together on your system. The detail procedure can be shown below.
Step 1: Create a new project
- Create a new project in WPF Application
- Add a button in MainWindow and set the button Content property to be "Run".
- Add Spire.Pdf.Wpf.dll and System.Drawing as references. After adding the namespaces, you can view the below codes.
[C#]
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Graphics;
using Spire.Pdf.Barcode;
namespace PDFWPFbarcode
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
}
}
}
[VB.NET]
Imports System.Drawing Imports Spire.Pdf Imports Spire.Pdf.Graphics Imports Spire.Pdf.Barcode Namespace PDFWPFbarcode ''' ''' Interaction logic for MainWindow.xaml ''' Public Partial Class MainWindow Inherits Window Public Sub New() InitializeComponent() End Sub Private Sub button1_Click(sender As Object, e As RoutedEventArgs) End Sub End Class End Namespace
Step 2: Draw barcodes in PDF document
Create a PDF document, set its margin and add one page in it
[C#]
//Create a pdf document.
PdfDocument doc = new PdfDocument();
//margin
PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
PdfMargins margin = new PdfMargins();
margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Bottom = margin.Top;
margin.Left = unitCvtr.ConvertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Right = margin.Left;
PdfSection section = doc.Sections.Add();
section.PageSettings.Margins = margin;
section.PageSettings.Size = PdfPageSize.A4;
// Create one page
PdfPageBase page = section.Pages.Add();
float y = 10;
PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("Arial", 12f, System.Drawing.FontStyle.Bold), true);
[VB.NET]
'Create a pdf document.
Dim doc As New PdfDocument()
'margin
Dim unitCvtr As New PdfUnitConvertor()
Dim margin As New PdfMargins()
margin.Top = unitCvtr.ConvertUnits(2.54F, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point)
margin.Bottom = margin.Top
margin.Left = unitCvtr.ConvertUnits(3.17F, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point)
margin.Right = margin.Left
Dim section As PdfSection = doc.Sections.Add()
section.PageSettings.Margins = margin
section.PageSettings.Size = PdfPageSize.A4
' Create one page
Dim page As PdfPageBase = section.Pages.Add()
Dim y As Single = 40
Dim font1 As New PdfTrueTypeFont(New Font("Arial", 12F, System.Drawing.FontStyle.Bold), True)
