A Comparison Between IronBarcode & QrCoder C#

IronBarcode

IronBarcode is a library created and maintained by Iron Software that enables C# software engineers to read and write barcodes and QR codes in .NET applications and websites. It is available on NuGet for all .NET Frameworks and .NET Core Frameworks. IronBarcode requires only one line of code to read or write barcodes.

QrCoder

QRCoder is a simple C# library that allows you to create QR codes. It has no dependencies on other libraries and is available on NuGet in .NET Framework and .NET Core PCL versions.

Both libraries should have the following main features:

• Scan QR code
• Scan barcode
• Generate QR code
• Generate barcode

We will implement all of these features from both libraries and compare their performance.

First, let's install both libraries in our Visual Studio project. Since both libraries have their own NuGet packages, we will install them via the NuGet Package Manager Console.

Install IronBarcode

To install IronBarcode, type the following command in the Package Manager Console:

Install-Package BarCode

This will install the IronBarcode library in our project.

Now, we will generate our first QR code using both libraries.

Generate QR codes using IronBarcode

The following code will generate a QR code.

using System;
using System.Diagnostics;
using IronBarCode;

class Program
{
    static void Main()
    {
        // Create a stopwatch to measure the execution time
        Stopwatch stopwatch = new Stopwatch();
        stopwatch.Start();

        // Generate a QR code
        var qrCode = QRCodeWriter.CreateQrCode("Iron Barcode Vs QrCoder");

        // Save the generated QR code as a PNG file
        qrCode.SaveAsPng(@"D:\Barcode Images\QrCodeByIronBarcode.png");

        // Stop the stopwatch and output the execution time
        stopwatch.Stop();
        Console.WriteLine($"Execution Time: {stopwatch.ElapsedMilliseconds} ms");
    }
}

using System;
using System.Diagnostics;
using IronBarCode;

class Program
{
    static void Main()
    {
        // Create a stopwatch to measure the execution time
        Stopwatch stopwatch = new Stopwatch();
        stopwatch.Start();

        // Generate a QR code
        var qrCode = QRCodeWriter.CreateQrCode("Iron Barcode Vs QrCoder");

        // Save the generated QR code as a PNG file
        qrCode.SaveAsPng(@"D:\Barcode Images\QrCodeByIronBarcode.png");

        // Stop the stopwatch and output the execution time
        stopwatch.Stop();
        Console.WriteLine($"Execution Time: {stopwatch.ElapsedMilliseconds} ms");
    }
}

Imports System
Imports System.Diagnostics
Imports IronBarCode

Friend Class Program
	Shared Sub Main()
		' Create a stopwatch to measure the execution time
		Dim stopwatch As New Stopwatch()
		stopwatch.Start()

		' Generate a QR code
		Dim qrCode = QRCodeWriter.CreateQrCode("Iron Barcode Vs QrCoder")

		' Save the generated QR code as a PNG file
		qrCode.SaveAsPng("D:\Barcode Images\QrCodeByIronBarcode.png")

		' Stop the stopwatch and output the execution time
		stopwatch.Stop()
		Console.WriteLine($"Execution Time: {stopwatch.ElapsedMilliseconds} ms")
	End Sub
End Class

The Stopwatch instance is created to measure the execution time of the program to analyze the efficiency of the library.

Create a QR code with QRCoder

The following sample code will generate a QR code using QrCoder.

using System;
using System.Drawing;
using QRCoder;

class Program
{
    static void Main()
    {
        // Initialize the QRCodeGenerator
        QRCodeGenerator qrGenerator = new QRCodeGenerator();

        // Generate QRCodeData with specified error correction level
        QRCodeData qrCodeData = qrGenerator.CreateQrCode("Iron Barcode Vs QrCoder", QRCodeGenerator.ECCLevel.Q);

        // Create QRCode object
        QRCode qrCode = new QRCode(qrCodeData);

        // Convert QRCode to Bitmap
        Bitmap qrCodeImage = qrCode.GetGraphic(20);

        // Save the QR code as a PNG file
        qrCodeImage.Save(@"D:\Barcode Images\QrCodeByQrCoder.png");
    }
}

using System;
using System.Drawing;
using QRCoder;

class Program
{
    static void Main()
    {
        // Initialize the QRCodeGenerator
        QRCodeGenerator qrGenerator = new QRCodeGenerator();

        // Generate QRCodeData with specified error correction level
        QRCodeData qrCodeData = qrGenerator.CreateQrCode("Iron Barcode Vs QrCoder", QRCodeGenerator.ECCLevel.Q);

        // Create QRCode object
        QRCode qrCode = new QRCode(qrCodeData);

        // Convert QRCode to Bitmap
        Bitmap qrCodeImage = qrCode.GetGraphic(20);

        // Save the QR code as a PNG file
        qrCodeImage.Save(@"D:\Barcode Images\QrCodeByQrCoder.png");
    }
}

Imports System
Imports System.Drawing
Imports QRCoder

Friend Class Program
	Shared Sub Main()
		' Initialize the QRCodeGenerator
		Dim qrGenerator As New QRCodeGenerator()

		' Generate QRCodeData with specified error correction level
		Dim qrCodeData As QRCodeData = qrGenerator.CreateQrCode("Iron Barcode Vs QrCoder", QRCodeGenerator.ECCLevel.Q)

		' Create QRCode object
		Dim qrCode As New QRCode(qrCodeData)

		' Convert QRCode to Bitmap
		Dim qrCodeImage As Bitmap = qrCode.GetGraphic(20)

		' Save the QR code as a PNG file
		qrCodeImage.Save("D:\Barcode Images\QrCodeByQrCoder.png")
	End Sub
End Class

QrCoder does not provide a built-in function to save the QR code as an image. However, we can save it by parsing the QrCoder into a Bitmap object. We can then save the QR code using the save function provided by Bitmap.

Generate a barcode using QrCoder

It's worth noting that the QrCoder library does not provide the functionality to create barcodes. Therefore, if you need to create barcodes, IronBarcode is the better option.

With regards to QR code scanning, let's see which library is the best option.

Read a QR Code using IronBarcode

The following code will read a QR code using IronBarcode.

using System;
using IronBarCode;

class Program
{
    static void Main()
    {
        // Read QR code from an image file
        BarcodeResults results = BarcodeReader.Read(@"D:\Barcode Images\QrcodeByIronBarcode.png");

        // Check if any QR codes are found
        if (results != null)
        {
            // Loop through each result and print extracted text
            foreach (BarcodeResult result in results)
            {
                Console.WriteLine("Extracted text from QR Code is: " + result.Text);
            }
        }
    }
}

using System;
using IronBarCode;

class Program
{
    static void Main()
    {
        // Read QR code from an image file
        BarcodeResults results = BarcodeReader.Read(@"D:\Barcode Images\QrcodeByIronBarcode.png");

        // Check if any QR codes are found
        if (results != null)
        {
            // Loop through each result and print extracted text
            foreach (BarcodeResult result in results)
            {
                Console.WriteLine("Extracted text from QR Code is: " + result.Text);
            }
        }
    }
}

Imports System
Imports IronBarCode

Friend Class Program
	Shared Sub Main()
		' Read QR code from an image file
		Dim results As BarcodeResults = BarcodeReader.Read("D:\Barcode Images\QrcodeByIronBarcode.png")

		' Check if any QR codes are found
		If results IsNot Nothing Then
			' Loop through each result and print extracted text
			For Each result As BarcodeResult In results
				Console.WriteLine("Extracted text from QR Code is: " & result.Text)
			Next result
		End If
	End Sub
End Class

IronBarcode returns an Enumerable as a result of reading QR codes. We need to loop through the Enumerable to retrieve each result. This feature is beneficial for reading QR codes from a document or from an image that has more than one QR code.

The time it takes IronBarcode to read/scan all QR codes from a document

It takes 3136 ms or 3.1 seconds using IronBarcode.

Read a QR Code using QrCoder

The QrCoder Library does not provide the functionality for reading or scanning a QR Code.

        BarcodeResults results = BarcodeReader.Read(@"D:\Barcode Images\BarcodeByIronBarcode.png");

        // Check if any barcodes are found
        if (results != null)
        {
            // Loop through each result and print extracted text
            foreach (BarcodeResult result in results)
            {
                Console.WriteLine("Text Extracted from Barcode is: " + result.Text);
            }
        }
    }
}

using System;
using IronBarCode;

class Program
{
    static void Main()
    {
        // Read barcode from an image file
        BarcodeResults results = BarcodeReader.Read(@"D:\Barcode Images\BarcodeByIronBarcode.png");

        // Check if any barcodes are found
        if (results != null)
        {
            // Loop through each result and print extracted text
            foreach (BarcodeResult result in results)
            {
                Console.WriteLine("Text Extracted from Barcode is: " + result.Text);
            }
        }
    }
}

			' Loop through each result and print extracted text
			For Each result As BarcodeResult In results
				Console.WriteLine("Text Extracted from Barcode is: " & result.Text)
			Next result
		End If
	End Sub
End Class

IronBarcode returns Enumerable as a result of reading barcodes. We need to loop through it to get each result. It is beneficial for reading Barcode from a document or image which have more than one barcode.

The output generated by the above code is as:

Read a Barcode using QrCoder

QrCoder Library does not provide the functionality of reading or scanning QR Code.

Now, Let's discuss the license options of both libraries.

Licensing

Licensing for IronBarcode

IronBarcode is free for development. However, It requires a license for deployment outside of the visual studio development environment. License price range from $liteLicense to $unlimitedLicense (USD). You can get a discount if you purchase the complete Iron Suite.

Check out IronBarcode's [licensing page](/csharp/barcode/licensing/) for more information about available licenses.

When to use QrCoder

If we only need the functionality of generating QR codes, QRCoder is the best option to use as it is free to use and doesn't require any payment or subscription fees.

When to use IronBarcode

IronBarcode is a great option when we require functionalities beyond generating QR codes, such as:

• Reading single or multiple barcodes and QR codes from images or PDFs.
• Image correction for skewing, orientation, noise, low resolution, contrast, etc.
• Creating barcodes and applying them to images or PDF documents.
• Embedding barcodes into HTML documents.
• Styling barcodes and adding annotation text.
• QR code writing that allows adding logos, colors, and advanced QR alignment.

Conclusion

IronBarcode for .NET allows developers to read and write barcodes and QR codes in their .NET applications using just one line of code. The library supports most barcode and QR code standards, including 39/93/128, UPC A/E, EAN 8/13, and QR, among others. The library automatically pre-processes barcode images and offers correction for rotation, noise, distortion, and skewing to improve speed and accuracy. IronBarcode is compatible with 32- and 64-bit systems, all .NET languages, and a variety of platforms, including desktop, console, cloud, and mobile and web applications. It also allows developers to write barcodes and QR codes for PDF, JPG, TIFF, GIF, BMP, PNG, and HTML documents, and modify text color, size, rotation, and quality. The library is secure and does not use web services or send data across the internet. IronBarcode is available for a free trial and offers three licensing options, including a Lite version for individual use, a Professional package for teams of up to 10 developers, and an Unlimited package for companies.

QRCoder is a C# .NET library that generates QR codes based on ISO/IEC 18004 without dependencies on other libraries. It offers several QR code rendering classes, including QRCode, ArtQRCode, AsciiQRCode, and others. However, not all renderers are available on all target frameworks, and the .NET Standard/.NET >=5.0 versions have some constraints. QRCoder is free and does not require licensing.

IronBarcode is more versatile than QrCoder since it offers support for all .NET Framework versions, has a wider range of features, and provides SaaS and OEM Redistribution coverage. IronBarcode also provides comprehensive documentation and 24/7 support, while QRCoder does not. IronBarcode has a licensing fee, but it is reasonable considering the features and support it offers.

IronBarcode is a library developed by Iron Software, which also offers other useful libraries, including IronPDF, IronXL, IronOCR, and IronWebScraper. Purchase the complete Iron Suite to get all five products at a remarkable discount.

In summary, IronBarcode is best suited for those who need to work with both barcodes and QR codes and want to create a barcode generator, QR code generator, barcode reader, and QR code reader. On the other hand, QRCoder is suitable for those who only need to create a QR code generator.
