If you already have an electronic image of the barcode in tech phone/admin phone and want to decipher it as English text data, a barcode scanner might not be the best tool. Additionally, barcode scanners are limited to reading only 1-D barcodes which have restricted storage capacity, domain status, supported formats and can only be used with the Windows RT Class library. Nowadays, 2-D barcodes (also called QR codes) are more common and can store significantly more information like updated date.
A barcode scanning application can run on Windows, MacOS, or Linux without relying on any third-party tools or APIs since it is supported by .NET.
Creating and scanning barcodes has become essential for many businesses to avoid spam. Two popular tools for creating barcodes are the open source ZXing project decode and IronBarcode. In this article, we'll explore the features and benefits of each of these tools and compare them.
ZXing is a popular open-source library for generating and decoding 1D and 2D barcodes.
It also supports multiple programming languages, including Java, C++, and .NET.
The ZXing Decoder Online is a web-based tool that enables users to scan and decode barcode and QR code images. Additionally, users can create QR codes for any information, which is usually in the form of a URL or text that they want to encode.
To use the ZXing online decoder, follow these steps:
Visit the ZXing Decoder Online website.
Once you have selected the image, click the "Submit" button.
The library is easy to use and can be integrated into web applications, mobile apps, and desktop applications.
ZXing has been widely adopted and has a large community of developers contributing to its development and providing support.
The library collects device information such as the device model and OS version, which can be considered a potential security risk.
Additionally, some have raised concerns over the ownership and control of the library, as it is not maintained by an independent organization.
Overall, ZXing is a powerful and versatile library for barcode generation and decoding, with widespread adoption and community support.
To generate a QR code using ZXing, for example, developers only need to write a few lines of code:
using ZXing;
using ZXing.QrCode;
// Create a BarcodeWriter instance to generate QR codes
BarcodeWriter writer = new BarcodeWriter
{
Format = BarcodeFormat.QR_CODE // Set format to QR_CODE
};
// Generate a QR code with the text "Hello, ZXing!"
Bitmap qrCode = writer.Write("Hello, ZXing!");
using ZXing;
using ZXing.QrCode;
// Create a BarcodeWriter instance to generate QR codes
BarcodeWriter writer = new BarcodeWriter
{
Format = BarcodeFormat.QR_CODE // Set format to QR_CODE
};
// Generate a QR code with the text "Hello, ZXing!"
Bitmap qrCode = writer.Write("Hello, ZXing!");
Imports ZXing
Imports ZXing.QrCode
' Create a BarcodeWriter instance to generate QR codes
Private writer As New BarcodeWriter With {.Format = BarcodeFormat.QR_CODE}
' Generate a QR code with the text "Hello, ZXing!"
Private qrCode As Bitmap = writer.Write("Hello, ZXing!")
To decode a QR code using the ZXing project, developers can use the following code:
using ZXing;
using ZXing.QrCode;
// Create a BarcodeReader instance for decoding QR codes
BarcodeReader reader = new BarcodeReader();
// Decode the QR code from a bitmap image
Result result = reader.Decode(qrCode);
// Extract the text from the decoded QR code
string text = result.Text;
using ZXing;
using ZXing.QrCode;
// Create a BarcodeReader instance for decoding QR codes
BarcodeReader reader = new BarcodeReader();
// Decode the QR code from a bitmap image
Result result = reader.Decode(qrCode);
// Extract the text from the decoded QR code
string text = result.Text;
Imports ZXing
Imports ZXing.QrCode
' Create a BarcodeReader instance for decoding QR codes
Private reader As New BarcodeReader()
' Decode the QR code from a bitmap image
Private result As Result = reader.Decode(qrCode)
' Extract the text from the decoded QR code
Private text As String = result.Text
IronBarcode is a powerful barcode generation and scanning library for .NET developers, created by Iron Software.
IronBarcode provides an easy-to-use API that allows developers to generate and scan various barcode types, including QR codes, Data Matrix codes, and UPC-A barcodes.
The IronBarcode library was created by Iron Software as a way to extend the functionality of the ZXing.NET library.
It adds new features and functionality, such as the ability to generate 2D barcodes, PDF417 barcodes and the ability to read barcodes directly from image files.
Here's an example of how to generate a QR code using IronBarcode:
using IronBarCode;
// Generate a QR code with the text "Hello, IronBarcode!"
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
// Save the generated QR code as a PNG image
barcode.SaveAsImage("qrcode.png");
using IronBarCode;
// Generate a QR code with the text "Hello, IronBarcode!"
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
// Save the generated QR code as a PNG image
barcode.SaveAsImage("qrcode.png");
Imports IronBarCode
' Generate a QR code with the text "Hello, IronBarcode!"
Private barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode)
' Save the generated QR code as a PNG image
barcode.SaveAsImage("qrcode.png")
To scan a barcode using IronBarcode, you can use the following code:
using IronBarCode;
// Read the QR code from the image file "qrcode.png"
var barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode);
// Extract the text from the decoded QR code
string text = barcode.Text;
using IronBarCode;
// Read the QR code from the image file "qrcode.png"
var barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode);
// Extract the text from the decoded QR code
string text = barcode.Text;
Imports IronBarCode
' Read the QR code from the image file "qrcode.png"
Private barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode)
' Extract the text from the decoded QR code
Private text As String = barcode.Text
IronBarcode supports a wide range of barcode types, including 2D Barcode, UPC-A, UPC-E, EAN-8, EAN-13, Code39, Code128, PDF417, and many more.
It builds on the strengths of the ZXing.NET library, providing faster, more accurate barcode scanning and generation while also adding new features and functionality.
Here are some steps on how to use IronBarcode:
To use IronBarcode in your .NET project, you first need to install the IronBarcode library using NuGet. You can do this by running the following command in the NuGet Package Manager Console:
Install-Package BarCode
To generate a barcode using IronBarcode, you can use the BarcodeWriter class.
using IronBarCode;
// Generate a QR code with the text "Hello, IronBarcode!"
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
// Save the generated QR code as an image file
barcode.SaveAsImage("qrcode.png");
using IronBarCode;
// Generate a QR code with the text "Hello, IronBarcode!"
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
// Save the generated QR code as an image file
barcode.SaveAsImage("qrcode.png");
Imports IronBarCode
' Generate a QR code with the text "Hello, IronBarcode!"
Private barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode)
' Save the generated QR code as an image file
barcode.SaveAsImage("qrcode.png")
This code creates a QR code with the text "Hello, IronBarcode!" and saves it as an image file named "qrcode.png".
To scan a barcode using IronBarcode, you can use the BarcodeReader
class.
using IronBarCode;
// Read the QR code from the image file "qrcode.png"
var barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode);
// Extract the text from the decoded QR code
string text = barcode.Text;
using IronBarCode;
// Read the QR code from the image file "qrcode.png"
var barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode);
// Extract the text from the decoded QR code
string text = barcode.Text;
Imports IronBarCode
' Read the QR code from the image file "qrcode.png"
Private barcode = BarcodeReader.ReadBarcode("qrcode.png", BarcodeEncoding.QRCode)
' Extract the text from the decoded QR code
Private text As String = barcode.Text
This code reads the QR code from the image file "qrcode.png" and returns the text that was encoded in the barcode.
IronBarcode provides a range of customization options that allow you to control the appearance and behavior of the generated barcode scanning implementation.
Here's an example of how to customize a QR code using IronBarcode for barcode scanning implementation:
using IronBarCode;
// Customize a QR code
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
barcode.ResizeTo(400, 400); // Resize the barcode
barcode.SetMargins(20); // Set margins around the barcode
barcode.SetForegroundColor(Color.Black); // Set the foreground color
barcode.SetBackgroundColor(Color.White); // Set the background color
barcode.AddCaptionAbove("Scan me with your smartphone!"); // Add a caption above the barcode
barcode.AddImageLogo("logo.png", 80, 80); // Add a logo to the barcode
barcode.SaveAsImage("qrcode.png"); // Save the customized barcode as an image
using IronBarCode;
// Customize a QR code
var barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode);
barcode.ResizeTo(400, 400); // Resize the barcode
barcode.SetMargins(20); // Set margins around the barcode
barcode.SetForegroundColor(Color.Black); // Set the foreground color
barcode.SetBackgroundColor(Color.White); // Set the background color
barcode.AddCaptionAbove("Scan me with your smartphone!"); // Add a caption above the barcode
barcode.AddImageLogo("logo.png", 80, 80); // Add a logo to the barcode
barcode.SaveAsImage("qrcode.png"); // Save the customized barcode as an image
Imports IronBarCode
' Customize a QR code
Private barcode = BarcodeWriter.CreateBarcode("Hello, IronBarcode!", BarcodeWriterEncoding.QRCode)
barcode.ResizeTo(400, 400) ' Resize the barcode
barcode.SetMargins(20) ' Set margins around the barcode
barcode.SetForegroundColor(Color.Black) ' Set the foreground color
barcode.SetBackgroundColor(Color.White) ' Set the background color
barcode.AddCaptionAbove("Scan me with your smartphone!") ' Add a caption above the barcode
barcode.AddImageLogo("logo.png", 80, 80) ' Add a logo to the barcode
barcode.SaveAsImage("qrcode.png") ' Save the customized barcode as an image
This code generates a QR code with the text "Hello, IronBarcode!" and customizes it by resizing it to 400x400 pixels, adding 20-pixel margins, setting the foreground color to black and the background color to white, adding a caption above the barcode, and adding a logo image.
IronBarcode is built on top of the open-source ZXing library, but it extends its capabilities to support a wider range of barcode types, including QR codes, Code 128, Code 39, EAN-13, EAN-8, UPC-A, and many more.
Here are some of the things that IronBarcode can do:
IronBarcode can easily generate barcodes of various types and styles, including linear and 2D barcodes, with customizable features such as colors, text, and image overlays. The following code snippet generates a QR Code:
var barcode = IronBarCode.BarcodeWriter.CreateBarcode("Hello World!", IronBarCode.BarcodeWriterEncoding.QRCode);
barcode.SaveAsJpeg("QRCode.jpg");
var barcode = IronBarCode.BarcodeWriter.CreateBarcode("Hello World!", IronBarCode.BarcodeWriterEncoding.QRCode);
barcode.SaveAsJpeg("QRCode.jpg");
Dim barcode = IronBarCode.BarcodeWriter.CreateBarcode("Hello World!", IronBarCode.BarcodeWriterEncoding.QRCode)
barcode.SaveAsJpeg("QRCode.jpg")
IronBarcode also provides a powerful barcode scanner that can read barcodes from images, PDFs, and live camera streams. The following code reads a QR Code from an image file:
var barcode = IronBarCode.BarcodeReader.Read("QRCode.jpg", IronBarCode.BarcodeReaderEncoding.QRCode);
Console.WriteLine(barcode.Text);
var barcode = IronBarCode.BarcodeReader.Read("QRCode.jpg", IronBarCode.BarcodeReaderEncoding.QRCode);
Console.WriteLine(barcode.Text);
Dim barcode = IronBarCode.BarcodeReader.Read("QRCode.jpg", IronBarCode.BarcodeReaderEncoding.QRCode)
Console.WriteLine(barcode.Text)
IronBarcode can also validate barcodes to ensure that they are valid and can be scanned by other barcode readers. The following code snippet validates a Code 128 barcode:
var barcode = IronBarCode.BarcodeReader.Read("Code128.jpg", IronBarCode.BarcodeReaderEncoding.Code128);
// Check if the barcode is valid
if (barcode.IsValid)
{
Console.WriteLine("Barcode is valid.");
}
else
{
Console.WriteLine("Barcode is invalid.");
}
var barcode = IronBarCode.BarcodeReader.Read("Code128.jpg", IronBarCode.BarcodeReaderEncoding.Code128);
// Check if the barcode is valid
if (barcode.IsValid)
{
Console.WriteLine("Barcode is valid.");
}
else
{
Console.WriteLine("Barcode is invalid.");
}
Dim barcode = IronBarCode.BarcodeReader.Read("Code128.jpg", IronBarCode.BarcodeReaderEncoding.Code128)
' Check if the barcode is valid
If barcode.IsValid Then
Console.WriteLine("Barcode is valid.")
Else
Console.WriteLine("Barcode is invalid.")
End If
IronBarcode can convert barcodes from one format to another, such as converting a Code 39 barcode to a QR Code. The following code snippet converts a Code 39 barcode to a QR Code:
var barcode = IronBarCode.BarcodeReader.Read("Code39.jpg", IronBarCode.BarcodeReaderEncoding.Code39);
var qrCode = IronBarCode.BarcodeWriter.CreateBarcode(barcode.Text, IronBarCode.BarcodeWriterEncoding.QRCode);
qrCode.SaveAsJpeg("QRCode.jpg");
var barcode = IronBarCode.BarcodeReader.Read("Code39.jpg", IronBarCode.BarcodeReaderEncoding.Code39);
var qrCode = IronBarCode.BarcodeWriter.CreateBarcode(barcode.Text, IronBarCode.BarcodeWriterEncoding.QRCode);
qrCode.SaveAsJpeg("QRCode.jpg");
Dim barcode = IronBarCode.BarcodeReader.Read("Code39.jpg", IronBarCode.BarcodeReaderEncoding.Code39)
Dim qrCode = IronBarCode.BarcodeWriter.CreateBarcode(barcode.Text, IronBarCode.BarcodeWriterEncoding.QRCode)
qrCode.SaveAsJpeg("QRCode.jpg")
