Scan Barcodes using IronBarcode

Utilizing the IronBarcode Library simplifies the process of barcode scanning, allowing for the effortless creation of a customized barcode reader. With minimal effort required, developers can easily implement barcode scanning functionality into their applications. This seamless integration enhances user experience and streamlines workflows.

Let's proceed by scanning the following barcode.

Steps to create Barcode Scanner API for WEB Application: Figure 3 - Barcode Image

The following code will input the above barcode image and return its value.

using IronBarCode;
using System;
var resultFromFile = BarcodeReader.Read("myBarcode.jpeg"); 
foreach (var result in resultFromFile)
{
    Console.WriteLine($"Barcode Value = {result}"); 
}
using IronBarCode;
using System;
var resultFromFile = BarcodeReader.Read("myBarcode.jpeg"); 
foreach (var result in resultFromFile)
{
    Console.WriteLine($"Barcode Value = {result}"); 
}
Imports IronBarCode
Imports System
Private resultFromFile = BarcodeReader.Read("myBarcode.jpeg")
For Each result In resultFromFile
	Console.WriteLine($"Barcode Value = {result}")
Next result
VB   C#

In the above code, the BarcodeReader.Read() method scans barcodes to read the barcode information from an image file named "myBarcode.jpeg". The result is stored in the variable "resultFromFile", which is then iterated over using a for each loop.

The value is printed to the console using the Console for each barcode detected in the image. This code demonstrates a straightforward approach for scanning barcode data from an image file using the IronBarcode library in a C# environment. In this way, we can add reliable scanning capabilities to our Web Application with just a few lines of code.

Scanning barcodes from an Invoice/ PDF

Scanning barcodes from an invoice or PDF document is a straightforward process with the IronBarcode Library. By leveraging its capabilities, developers can efficiently extract barcode information from these documents, enabling seamless integration into their applications. This functionality enhances data processing efficiency and facilitates tasks such as inventory management, invoice processing, and document organization.

Let's proceed by scanning the following barcode.

The following code will take the provided invoice PDF as input, detect all barcodes present within it, and return their values.

using IronBarCode;
using System;
static void Main(string[] args)
{
    var barcodes = BarcodeReader.Read("invoice.pdf");
    for(int i = 0; i < barcodes.Count; i++)
    {
        Console.WriteLine($"Barcode  {i+1} = {barcodes[i]}");
    }
}
using IronBarCode;
using System;
static void Main(string[] args)
{
    var barcodes = BarcodeReader.Read("invoice.pdf");
    for(int i = 0; i < barcodes.Count; i++)
    {
        Console.WriteLine($"Barcode  {i+1} = {barcodes[i]}");
    }
}
Imports IronBarCode
Imports System
Shared Sub Main(ByVal args() As String)
	Dim barcodes = BarcodeReader.Read("invoice.pdf")
	For i As Integer = 0 To barcodes.Count - 1
		Console.WriteLine($"Barcode  {i+1} = {barcodes(i)}")
	Next i
End Sub
VB   C#

The above code snippet utilizes the IronBarcode library to extract barcode data from an invoice PDF. It reads the PDF file, detects all barcodes within it, and then iterates through each barcode found. For each barcode detected, it prints out its value along with its corresponding index in the list of barcodes. This process enables efficient retrieval of barcode information from the PDF for further processing or analysis.

Creating Barcode

To create a barcode using IronBarcode in a .NET project, developers can utilize the library's versatile functionality. Developers can generate various types of barcodes, including QR codes, Code 128, UPC-A, and more with just a few lines of code.

The following code will create a barcode, resize it, and save it as a PNG file.

var barcode = BarcodeWriter.CreateBarcode("1122000399485533466", BarcodeEncoding.Code128);
barcode.ResizeTo(600, 400);
barcode.SaveAsPng("barcode.png");
var barcode = BarcodeWriter.CreateBarcode("1122000399485533466", BarcodeEncoding.Code128);
barcode.ResizeTo(600, 400);
barcode.SaveAsPng("barcode.png");
Dim barcode = BarcodeWriter.CreateBarcode("1122000399485533466", BarcodeEncoding.Code128)
barcode.ResizeTo(600, 400)
barcode.SaveAsPng("barcode.png")
VB   C#

The above code snippet demonstrates how to create a barcode using IronBarcode in a .NET project. In this example, a barcode is generated using the BarcodeWriter.CreateBarcode() function with the data "1122000399485533466" encoded in the Code 128 format.

The generated barcode is then resized to dimensions of 600x400 pixels to suit specific requirements. Finally, the barcode is saved as a PNG image file named "barcode.png", ready for use in various applications such as product labeling, inventory management, and document processing.
